' -According to thepresentinventioii, an instrument'is provided giving the advantages of freeing a living artery, yet drastically reducing operating time.

Therefore, it is an object of this invention to provide an instrument usable in treatment of arteriosclerotic occlusive disease.

Another object of this invention is to remove an obstruction in an artery without extensive suturing.

A further object of this invention is to materially reduce operating time in the treatment of such cases.

Yet another object of this invention is to provide an instrument having-a short tubular cutting portion on the end of a flexible handle which may be inserted within an artery for removing an occlusion therein.

These and other objects will become apparent from the followingdetailed description taken in connection with the accompanying drawing in which:

Fig. 1 is a perspective view of the surgical instrument of this invention,

Fig. 2 is an enlarged fragmentary sectional view illustrating the forward cutting portion of the instrument,

Fig. 3 is an enlarged sectional view illustratingia' po'rtion of the artery prepared for removal ofthe occlusion by theinstrument of this invention,

' Fig.4 is a fragmentary perspect ve view of the v ment used in its initial stage in freeing the interio'r of an from 'withinan artery, and Fig. 6 is an elevational view, partially broken away,

of a modified form of flexible handle for the instrumen Fig. 5 is an enlarged-sectional view showing the instrument of this inventionduring its removal of an occlusion 7 ',It 1 s. important in the next phase of the operation to start the cleavage planeproperly between the thickened intima., and,the surrounding media. "Thus, vas seen in 131g 3, beveledcut.liljis-rnade in loosening intima 11 from the interior of ,artery 12 at the. location of short longitudinal incision 13. prevents subsequent dissection of the distal intimal edge when blood flow is reestablished. After this beveled incision has been accomplished'carefully around the entire inner circumference of the artery, instrument 1 is threaded on intima 11 in the manner illustrated in Fig. 4. The intima is received by the interior of tubular member 3 with cutting face 4 at the forward edge toward the occluded section of the artery. as best seen in Fig. 5 which frees the thickened intima from the arterial wall. Tubular section 3 is gently forced forwardly by handle 2 extending through incision 13 into the artery a distance suflicient to free the entire obstruction portion. The substantially inclination of the cutting face has been found to give optimum results in advancing .the cleavage plane. Other angular relationshipswmay be used successfully if not as effectively.

When the occluding portion has been freed by the instrument'of this invention, it may be pulled fromthe artery through-incision 13, following which the instrument also is removed and the necessary sutures are made.

It can be seen from the foregoing, therefore, that. it

is possible by the use of the instrument of this invention to' remove a lengthy obstruction from within an artery whilemaking only a small incision in the wall of the that operating time is greatly reduced and that improved results are obtained. q

The instrument of this invention maybe made in various sizes so that arteries of different diameters may be successfully operated upon. Preferably a number of instruments of graduated sizes are supplied in a surgical kit so that whatever the size of the vessel encountered a properly, dimensioned instrument will be available. The outer diameter of the tubular section may vary considerably from around .110 inch to nearly one-half inch 2,944,552" Patented July 12,1960

given a slight twist as illustrated. Helically wrapped around the exterior ofportion 14 is an additional'wirelS entirely covering the central portion throughout its length. This provides a strong, flexible handle which has some rigidity in the axial direction, but which also will retain a curvature impartedto it.

Theins trumentxis comparatively simple'to construct and use, and'with the front cuttingedge inclined forwardly at approximately 70 as described above, an eflective. cleavage of the thickened intima is obtained.
