Abstract

LEAKPROOF HEMOSTASIS VALVE WITH SINGLE VALVE MEMBER

ABSTRACT OF THE DISCLOSURE

A hemostasis valve in which the valve member is a tubular, resilient gasket which may be compressed with variable pressure to provide a variable pressure seal to an elongated member extending through the tubular bore of the gasket. The gasket gore also defines at least one resilient, annular rib whereby the elongated member passing through the tubular gasket bore may be subjected at all times to at least a relatively low pressure seal from the resilient, annular rib, irrespective of the pressure of the variable pressure seal. Additionally, the pressure on the gasket may be applied and released by means of a pressure member positioned against the gasket. Means are provided permitting longitudinal motion, but preventing rotational motion, of the pressure member. A rotatable cap is provided, with facing, mating spiral track means carried on both the inner face of the rotatable cap and outer face of the pressure member, to cause pressurizing advancement of the pressure member against the tubular gasket by rotation of the cap in one direction, and release of such pressurizing advancement by rotation of the cap in the other direction.

Description

BACKGROUMD OF THE INVENTION
The present invention relates to lea]cprooE hemo-stasis valves.
In Bales, et al, U.S~ Patent No. 4,726,374, a hemo-stasis valve which is improved over other prior artversions is disclosed. Hemostasis valves are currently on catheters for perfcrming percutaneous transluminal coronary angioplasty (PTCA), as well as angiographic procedures, for example, where x-ray contrast fluid is inserted into the coronary artery.
In PTCA, stenotic regions of coronary blood vessels are dilated by advancing a dilation catheter through blood vessels into the stenotic region. The dilatation catheter advances over a guide wire, which guide wire moves forward, followed by the catheter, followed by another advance of the guide wire, etc. The guide wire-dilatation catheter system may be introduced through a guiding catheter to fa,cilitate its placement.
To prevent the leakage of blood out of the proximal end of the catheter, a hemostasis valve is provided at the proximal end, to prevent seepage of blood between the guide wire and the catheter. Besides the desiyn shown in the above-cited patent, numerous other types of hemostasis valves are known. See for example Stevens, 25 U.S. Patent No. 4,000,739. Another design of hemostasis valve is the Tuohy-Borst type, making use of an adjust-able, compressive sleeve which is axially compressed ~.~9~
2a about the guide wire that it seals by means of a two-piece, screw threaded housing. Other designs may use an "O" ring and a ~-~9~

topered 028t ln~ead of a ~leeve.
Msny desi~ns require tl8htening of the ~alve ~hen high pres~ure ~-r~g contr~t fluid or the like i~ run through the catheter. Ho~ever, ~ith ~uch high pressure sealing, ~he guide vire cannot be sdvanced in efective ~anner, so the ~al~e, BUCh S8 B Tuohy-bor6t ~lv~, ~u~t be loosened 80 thBt the operator can "feel" any resistance encountered by the orwsrd sdYancement of thP ~ulde wire, durin~ the oper~tion of ad~ncing the guide vire through blo~d ~e~els.
The degree of loosen~n~ of the ~alve can be critical. If excessively loosened, low pressure le&kage ~y occur. If loosened too lietle, the guide ~ire cannot be effecti~ely ad~anced. Accordingl~, lt turns out that for the ~06t effecti~e perfor~ance of PTCA ~nd an~iogr~phy procedures, a hemostasis ~alYe ~hich i8 highly controllable i8 needed, 60 that the guide ~ire can be easil~ ~dv~nced, ~hile low pressure leakage i6 prevented on an e~sy, reliable bQsis, without the Deed for gre~t skill and experience in operation of the vnlve.
Thus ~ he~ostasi6 YalYe should be provided with reliable sealing against lo~ pressure leakaee ~round ~ guide ~lre or the like. At the same time, an ad~ustable ~eal should al60 be pro~ided whlch ~y be adjusted ~o seal ~gai~st high pressures. Accordingly, the ~djustable seal ~ay be spplied or released as desired, but, preferabl~ ~t lesst a lo~ pressure seal ~a~ be constantly present to stop leakage upon release of the high pres~ure seal. Thus, ~anipulation of the high pressure ~e~l is less critical, and requires less skill in order to avoid leakage.
Also, the surgeon who is manipulating a typical catheter for entering coronary blood vessels, for exam-ple, is overburdened with respect to things to hold and manipulate during this process. The hemostasis valve described above provides improved efficiency of adjust-ment of the adjustable valve, to relieve the burden on the surgeon.
While the invention of the cited U.S. patent No.
~,726,374 provides improved efficiency of adjustment, it does so by the addition of a second sealing site, spaced from a first adjustable, compressible sleeve valve which is provided to give the variable pressure sealing. It is of course a complexity of manufacture to provide a second sealing site, requiring a second sleeve or gasket.
By this invention, improved efficiency of adjust-ment of the hemostasis valve of this invention can be provided through the use of a single, compressible tubular sleeve or gasket. In this gasket, high pressure sealing may be applied, or released, to alternatively permit the application of high pressure x-ray contrast fluid or the like, and also to permit advancement of catheters and guide wires without blood leakage through the application of a low pressure seal which remains, ~ven when the high pressure seal is released. Despite this, the advantage remains that only a single 4a resil.ient, tubular gasket is present to provide bokh of these functions.
Additionally by this invention, an improved struc-ture for application and release o* the adjustable, high pressurizable seal is provided.
DE5CRIPTION OF_THE_I E TION
In accordance with the presenk invention, there ls provided a guide~wire dilatation catheter system, which comprises a dilatation catheter for receiving a guide-wire, a guide-wire and a hemosta~is valve connected to the proximal end of the catheter. The hemostasis valve comprises a housing having a first bore extending through the housing, the housing bore de~ining an enlarged chamber portion which has an open outer end and which carries and retains a single, unitary tubular, resilient gasket having a second bore defined by a wall in generally coaxial relation with the first bore. The wall defining the second bore is adapted for variable compression about the guide-wire substantially through-out the entire length of the second bore.
Rotatable handle means are provided for rotating in one direction to pressurize the gasket to cause con-striction of the second bore and for rotating in the opposite direction to release the pressure on the gasket to permit e~pansion of the second bore, whereby guide-means passing through the second bore may be subjected to a variable pressure seal.
The second bore has a substantially uniform diameter throughout its length except that it has at least one resilient, annular rib extending radially inwardly, whereby the guide-wire passing through the 5a tubular gasket bore may be subjected at all times to at least a relatively low pre~sure seal from the resilient, annular rib irrespective o~ the pressure applied by the variable pressure seal.
~he tubular, resilient gasket may define a generally conical inner end. The corresponding inner end of the enlarged cha~ber portion may al~o be of a similar, ~.ts~ )O~

3enerallJ conicsl ~h~pe. The bore6 of the gasket ~nd hou~lng extend re~pecti~ely throu~h the spexes of the oon~cal ~hape~
of their inner en~s, ~o facilitate re~i~tr~tiDn of the bores as ehe gssket is tompressed, ~pecificslly exially compressed.
Typically, the resilient, annular rib is located ~djacent the ~enerslly conic~l inner end o the ga~ket.
However, the rib may be located at other positisns along the bore of fiaid tubular gssket. ~dditionally, 8 plurality of resilient ~nulBr ribB ~ be proYided ~ithi~ the bore of the . 10 ~ket if de~ired~
The housing typirally defines a br~nch tube for fluid flow therethrough, the brsnch tube being spnced from one tubulsr hou6ing end by the tubular g~sket.
Additionall7 or alternntl~el~, the he~o6ta~i~ val~e of thi~ in~ention may carry ~ particulurl~ ~d~ant~geous s~stem for co~pres6ing ~ tubular, resilient 8aaket for pro~iding 8 vnriable presfiure seal ag~ins~ an elon~ated oe~ber 6uch as ~ catheter end/or ~t~let positioned vithin the housin8 -The hou6ing defines ~ fir~t bore extendin~

This tubular, resilient ~asket ~Ry be of the t~pe pre~iously described 9 or ~ay be a gasket of the type used in the prior nr~. if desired.
A pressure ~e~ber i6 also carried in the enl~rged ~9~o~

cha~ber portion ~t an out~srd pD6ition fr~ salt ~a6ket. The pressure member defines 9 thlrd bore po~itioned in ~enerall~
coaxlsl relation with the fir6t ~nd ~econd bores. Means ~re proYided for permitting longitudinal ~otion but preYentinæ
rotational motion by the pressure ~ember.
A rotstable C8p iB pro~ided, closin~ the open 9 outer end of the enlarged chamber portion, the cap definin8 an aperture for access to the bores. F~cing, mating spiral tr~ck seans are carried on the inner fsce of the rotatsble cap ~nd the outer face of the pressure ~ember, to e~u~e pressurizing ad~ancement of the pressure ~ember a~ainst the tubular gesket b~ rotation of the C8p in one direetion, and release of ~uch pre~surizing sdv~ncement b~ rot~tion of the cap in the other directlon.

Luer lock connecter 14 c~rries ~ rotatable threaded out 16 vhich i~ carried by flange~ 18 on the bod~ of hou~ing 20 o ~he he~o~t~ slve. O-rin~ 22 ~a~ be pro~ided for sesling purpo~es, ~hile projecting tubular portion 24 of housing 20 communicates ~ith bore of cstheter 12.
Housing 20 define~ a first bore 26 of Y0riable di~eter extendin~ therethrough. Housing bore 26 define~ a~
enl~rged chamber portion 28 which has an Dpen, ou~er end as ~ho~n and ~hioh ree~ins a tubular, resilient gafiket 30 haYing a second bore 32 posl~ioned in genernlly coaxiel relation ~ith fir~t bore 26~
Rotn~able handle ~eans 34 are provided for rotating in one direction to longitudinally pressurize Basket 30, to cause constriction of second bore 32. Thus, ~ngiopl~st~
catheter 36, or sny other elongated me~ber extending through the bore defined ~.hrough hemostasis valve 10 msy be radi~lly compress~d within bore 32 of gasket 30 a~ ~hovn, for example, in Figl 2B. Catheter 36 is deleted from Figs. 2-3 for purposes of clear disclosure.
Handle 34 ~a~ be rota~ed in the opposlte direction to release pressure on ~asket 30, to permit expansion of .2 ~

~econd bore 32 as ~ho~n ln ~8- 2~. Thus, ~ny cstheter or other elongated ~ember residin8 in the bore 3~ which pa~se6 through hemostasi~ valve 10 ~ay be 6ubjected to a radiall~
compressl~e seal of variable pre~sure.
Tubular side arm 38 of vslve 10 defines a bore 40 ~hich communicates in branching relationship with bore 26 of housing 20. ~hus, 1uids such ~s x-ray contrast fluid may be - spplied throu~h side ~rm 38 to the bore of c~theter 12 in a P~CA procedure or the like, vhile ~slve 10 ls ln the configuration shown in Fig. 2B, ~o th~t hi~hly compressed 2s6ket 30 prevents leakege of contrast fluid around catheter 36 outwardly through the distsl end 42 of hemo6tasis val~e 10. However, when ~nd if it is dee~ed ad~isable to adYnnce cstheter 36, ~hich ~ay contain ~ flexible ~tglet or the like, the pressure on gasket 30 ~8y be released as 6hown in Fig. 2A
~o permit ~uch cd~ancement of the catheter throuRh ~ores 32 and 26.
In ~ccordance ~ith thi~ lnvention, to prevent backflow of blood or the like while odvancing ~ ~ember such as catheter 36, 8asket 30 defines st least one resilient, ~nnular, resilient rib 44 pro~ecting into the bore 32 of gasket 30. As the result of this, ~hen an elongated member such as catheter 36 extends through tubular gasket bore 32, and typicall~ through the entire l~ngth of ~slve 10, the elongated member ~ay be sub~ected ~t all ti~es to at least a relstively low pressure seal from resi~ient, annulnr rib 44, irrespecti~e of any added pressure applied by the variable pressure sesl ~hich is controlled by the position of hsndle 34. Thus, the le~k~e of blood or the like rearv~rdl~ out ~f proxi~al end 42 ~ay be preYented, BO th~t the 6urgeon does not need ~o vorr~ ~bout it a6 he proceeds ~leh hi6 PTCA
surgic~l procedure or ~ny other desired procedure.
If desired, added ~ealing rings correspondin~ to annuler rib 44 ~8y be pl~ced within bore 32 of g~sket 30.
Gasket 30 may define ~ ~ener~lly conical inner end 46. The corresponding inner end 4B of enlarged ch&mber 28, in Yhich gssket 30 resides, ~ay also be of si~ r, ge~erall~
conical sh~pe. Thls facilitatefi the registra~on of the constricted portion 50 of housing 20 ~ith bore 3? 8s g~sket 30 is axislly compressed.
Turning to the 6ystem by vhich gasket 20 ~ay be compressed or relea6ed from compression 88 de~ired, pre~sure member 52 i5 also csrried in enlerged chamber portion 28 ~t an outward or proximal position from Basket 30. Pressure ~ember 52 defines ~ third bore 54 positloned in generally coaxifll relation with first ~nd 6econd bores 26, 32.
Further~ore, pressure ~e~ber 52 resides in hou~ing 20 in a ~anner permitting its longitudinsl ~otion but preventin~ itB
rotationsl moeion. This i~ accompli~hed 88 sho~D in Fl~ 3 by providing ~ polygonal configurstion to the peripherg of pressure ~ember 52~ nnd a corresponding poly~on~l configuration to that section 56 of the bore of housing 20 in which pressure member 52 resides. Section 56 msy terminate at its distal or lnner end at annulsr step 60, and m&y extend eO the outer end of housiD~ 20. Projecting inner portion 57 of hsndle ~ember 34, on which spir~l track 66 is found, i8 Of ~all enough di~meter 80 ac not to be re~trlcted fro~
rotation by the pol~onal bore.
Thus 9 pres6ure ~ember 52 can be ~dv~nced ~nd retracted to longieudinally compress gssket 30, but it cannot rotate.
Handle ~ember 34 defines ~ rotstcble c~p, closing the open outer end of the enlarged chamber portion 28 of housing 20. C8p 34 defines an sperture 62 for ~ccess to bcres 54, 32, and 26. CBP 36 oay be eonvention~ a~t~ched by onap fit ~e~ns ~ ~ho~n in Fi~s. 2A and 2B.
Facin~, mating spir~l track ~e~ns 66, 68 sre respeetivel~ c&rried on the inner face of rot~t~ble cap 34 and the outer face of pressure 0e~ber 52, 80 that spiral track me~ns 66, 6B obut each other. As handle ~ember 34 is rotat~d9 8ince handle member 34 i8 offi~ed br a snsp-fit connection so that it cannot ~ove Axi~lly, pressure ~ember 52 i8 forced to ~oYe axially either in an ~dY~ncing direction, to pre6surize gasket 30, or ~ retracting direction to release such pressure. Thus control of the ~lvln~ ~ressure of gasket 30 i8 MChieVed. ~180, the presence of ot lenst one annular 6esling rib provides a cer~ain leYel of continuous, low pressure sealing for a catheter 36 ~hich extends through bore 32 in any rotational position of handle 34.
Thus~ by this inYention, a ~ingle, tubulflr g~sket provides both variable pressure sealing vith ~i~ultaneous, continuous, low pressure sealing, irrespective of the ad~ustment oE the vsriable pressure ae~l. This i8 accompli~hed b~ a novel means for i~position and release of l.Zg~OO~
