- AimftiJ'unet, 1951, serial 1510.229343 4 claims. (ci. 12tlg-349) This invention relates to animprovedinstrument for :supplying r'n'e'dicinalI substances to and thedrainng of fluid from .theprostate glandand the area surrounding said gland. A. 'l The primary object'of this invention vide a means for supplyingfmedicinal substances under pressure to and retaining the same in contact with vthe prostate gland and area surrounding the same. The device is designed for instilling medicinal substances into ducts and through the ducts of the prostate gland for any desired period of time, while preventing the medicinal substances from passing into the bladder. The device will also dilate the urethral wall so that there will be a dilation of the ducts leading off into the prostate gland and the seminal vesicles, thus facilitating the passage of the medicinal liquid into these'areas andthe passage of pus or like matterfrom these areas. The device can also be used to provide gentle pressure on the prostate gland from the interior of the urethra to assist inthe removal of fluids or like matter from the prostate gland and to be used in connection with prostatic massage for that purpose.

Another important object of this invention isl to provide a device of the character described which includes inflatable means which can seal off a particular area of the urethra so that medicinal substances can be delivered under pressure to the sealed off area or a vacuum may be applied to the device for the removal of fluid only from the sealed off area.

A further object of this'invention is to provide a device of the character vdescribed which is simple in construction, easy to use and very efficient for its intended purposes. i

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings,

' wherein:

Figure 1 is a longitudinal sectional view through the device; l g

Figure 2 is an enlarged fragmentary longitudinal sectional view of that portion of the device having the inflatable means;

Figure 3 is a sectional view taken substantially on the plane of section line 3-3 of Figure 2;

Figure 4 is a sectional view taken substantially on the plane of section line 4--4 of Figure 2; land Figure 5 is a sectional view taken` substantially on the plane of section line .5 5 of Figure 1.

Specific reference is now made to the drawings.` IVA-n the several views in the accompanying drawings and infthe following specification ref- -erence -`characters indicate corresponding elevments throughout. f v

y The'present device comprises an elongated cannula I0 of the usual flexible material, thedistal end bengrrounded as at ,I2 whereastheopposite end is `forked or bifurcated to provide two furcations I4 and IE. Extending lengthwise through the cannula and through the furcation I4'is a] f conduit or passage I8 of relatively small diameter adapted to convey air or other gases under pressure, the conduit terminating adjacent the distal end of the cannula.

In the vicinity of the distal end of the cannula, f

- thesame is provided with a pair of longitudinally spaced annular grooves 20 and 22 which communicate with the conduit I8 by means of ports 24 and 26. An elastic band 28, fabricated of suitable rubber or plastic, and which is substantially channel vin cross section, as shown 'in the drawings, is cemented vor otherwise fixedly secured within each groove in such a manner that nor.

` the penis in the urethra until the grooves 24 and 26 reach the region to be treated. The furcation I4 is then attached by a suitable adapter to a source of air or gas under pressure whereupon the bands lor sleeves 28 are inflated to assume the positions shown in dotted lines in Figure 1. This seals olf a desired area between the grooves and the furcation I6 mayithen be attached to a source of medicinal fluid for delivery of the same through the conduit 34 to the delivery opening 36 between thegrooves. The medicinal fluid may From the foregoing, the construction and opery ation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modications and equivalents may be resorted to, falling within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. An instrument for treating the prostate gland, seminal vesicles and the male posterior f urethra comprising an elongated cannularhaving a rounded somewhat blunt distal closed end adapted for unhampered insertion in the patients urethra and a bifurcated trailingv end, a rst conduit extending longitudinally-.through said cannula and one of the furcations and terminating at one end adjacent to said distal end,`-saidv conduit being adapted to receive and conduct gas under pressure, longitudinally spaced resiliently inflatable sleeves carried by said cannula and communicating with said conduit, saidsleeves being expandable under gas pressure to .enlarge the effective diameter of said cannula at .two longitudinally spaced positions, and a second medicinal fluid-conveying conduit extending longitudinally through said cannula and the other furcation, said second conduit terminating at one end in a discharge opening located midway between said spaced inflatable sleeves.

2. The combination of claim 1 wherein said iniiatable sleeves are characterized by a pair of longitudinally spaced annular grooves adjacent the distal end of said cannula, a port communi- .eating each of said grooves with said rst conduit, and an elastic endless band secured in each of said grooves.

3. The combination of claim 2 wherein said 4bands l .flush with the outer surface of said cannula when deated.

4. The combination of claim 3 wherein the diameter of said first conduit is substantially smaller than that of said second conduit.
