FREDERICK J. WALLACE I ATTORNEY.

Patented Aug. 18, 1953 N E S PATENT OFFICE CATHETER Frederick .1. Wallace, New York, Y.,:assignor to 'American'cystoscope Markets, Inc., New York, N. a-corpor'ation of New York Application October 26, 1949, "Serial'No. 123,7 41

4-'-Clalms.

This invention relates to surgical drains and more .part'icularlyto catheters adapted to be advantageously employed .in various urologicaljprocedures.

It is a principal object of the invention to provide a catheter having improved characteristics.

The invention has for another object .the .provision of .an indwelling catheter that may be readily. introduced into a body cavity, maintained in the cavity for an extended period of time Without accidental dislodgment, and subsequently removed.

A further object of theinvention is to provide an indwelling type of catheter which is capable of performing its intended functions .in an efficient and trouble-free manner.

To the end that the foregoing objects may be attained, a catheter constructed in accordance with this inventionpreferably comprises a tubular member closed atits forward end. and havinga drainage opening at its rearward .end. The tubular member is formed with a plurality of circumferentially spaced longitudinal slots adjacent the forward end. The entire tubular member is preferably flexible and distortable,-and is fabricatedso that the portions thereof defining the longitudinal slotsnormally project axially outwardly beyond adjacent portions.

The catheter is provided witha flexible means within the tubular member and anchored to the closed end. This means is adapted to retract the closed end of the tubular member with .respect to the other end to thereby flextheprojecting portions further outwardly. The catheter also includes means adapted to releasa'bly maintain the closed end of the'tubular member in retracted position.

'While the catheter of this invention may be made of any one of a variety of .materials, including rubber and certain synthetic resins, I recommend that the catheter 'be made from thermoplastic polyethylene.

It has heretofore generally been the practice to make indwelling catheters .of rubber. Experienc'e has'demonstrated that indwellingrubber catheters, when usedior long term drainage of "thebladdenoften become encrusted with deposits of urinary salts. Withdrawal of such catheters, after deposition or crystallization of urinary salts on their outer suriac'esfmaybe extremely-painful and may at times'require'an open operation before they can be-removed. Moreover, deposition of urinary salts reduced the lumen or drainage channel 'offthe catheter, thereby preventing adequate elimination of urine.

I "find that catheters constructed in accord-- ance with this invention and made of polyethylene may be readily inserted 'intoa body cavity, such as the bladder, retained in desired position in the bladder for an extended period of time, then readily removed without undue pain or injury to the patient.

Among the principal advantages of using polyethylene instead of conventional materials in catheters is that polyethylene catheters are nonirritating and non-toxic and donotsuppor-t the deposition and crystallization of urinary salts thereon. Further, polyethylene is smooth, chemically inert, and resistant to acids and alkalis; possesses requisite flexibility when extruded or molded into thin'tubes'; andhas a low water absorption factor, all of whichcharacteristics contribute material-1y to the value of polyethylene as a suitable catheter-material.

The enumeratedobjects, as well as other objects, together with'the advantages attainable by the practice of this'i-nvention, will be readily apparent to-persons skilled in the art upon reference to the *following detailed description, taken "in conjunction with the annexed drawing, which respectively describe and illustratea catheter constructed in-accordance with-the inventi'on.

-In the drawing:

Figure '1 is a--vi'ew in elevation of -a=-catheter emb odying the invention, partly'broken away and partly in central longitudinal cross section;

Figure "2 isa view taken along line '2-2 of Figure 1;

Figure Beorrespondsto Figure 1 and illustrates the parts of the catheter in another relative position;

Figure 4 is awiew inend=elevationas seen from the'rig'ht of Figure 3;

Figure '5 is a -view -.ta'-ken 'along -1ine'5 5 of Figured and Figure "6 is a view taken along line --'6'-6 ot Figure 3.

Referring to -the drawing, wherein like reference numerals denote corresponding parts throughout the-several views, .numeral I) generally indicates=a surgical drain tube or catheter, that 1 may be considered as being in the category of '-a Pezzar type 'catheter, and-comprises a tubular:mem-ber [2 close'd and rounded'at its forward end M to facilitate introductioninto-a body passage. The tubular member is open at its rearward end H; -for v drainage purposes, and is provided with a slot l8 that-mergeswith the rearward extremity. The tubular member irrcludes a plurality of outwardly projecting portions 2 0 Anchored within closed end 14 is a plug 24* having a central bore 26 and a recess 28.

ethylene, extends through-centralv bore 26 and has a head 32 that is positioned in plug recess 28 (Figure 5).

the member at the proper location.

For the purpose of outlining the manner of using the catheter, it is first assumed that the parts are in the relative position shown in Figure 1. A stylet (not shown) is inserted in tubular member [2 and its forward end is brought to bear against the rearward end of plug 24. The stylet is moved forwardly with respect to the tubular member, causing portions 29 to be extended due to their flexiblity, and the catheter and stylet are inserted in a body passage to the desired location, such as into the bladder. The stylet is then removed, allowing the parts of the catheter to return to the position shown in Figure 1.

To ensure retention of the catheter in the bladder, the rearward end of tubular member I2 is gripped in one hand and flexible member 30 is moved rearwardly with the other hand. This causes retraction of closed end I4 with respect to the other end of the tubular member and effects further outward projection of portions 20 until they assume the position shown in Figure 3. The parts of the tubular member are retained in the position shown in Figure 3 by bringing the portion of flexible member 30 immediately forward of enlarged part 34 in registry with slot I8 so that enlarged part 34 bears against the outer surface of tubular member 12.

When the parts are in the position shown in Figure 3, portions 3 6 of the tubular member constitute lateral wings that prevent accidental removal of the catheter from the bladder; and adequate drainage is obtained through openings 38, the interior of the tubular member, and open rearward end l6.

To withdraw the catheter from the bladder, flexible member 30 is placed out of registry with slot I8, allowing closed end 14 to be protracted from the position shown in Figure 3 to that of Figure 1. The catheter may then be removed or, if desired, a stylet may be inserted in tubular member l2 and actuated to further protract forward end M with respect to the remainder of the tubular member before removal.

Thus it will be seen that the construction herein shown and described is well adapted to accomplish the objects of the present invention. It will be understood, however, that the invention may beembodied otherwise than here shown, and that in the form illustrated certain obvious changes in construction may be made, Therefore, I do not wish to be limited precisely to the construction herein shown except as may be re quired by the appended claims considered with reference to the prior art.

I claim: 7 I 1. In a catheter, a tubular member closed at its Flexible member 30 has an enlarged part 34 that may be obtained by knotting A flexible member 3!], also preferably made of polyforward end and having a drainage opening at its rearward end, said tubular member having a plurality of circumferentially spaced longitudinal slots formed therein adjacent the forward end, the portions of the tubular member intermediate the extremities of the slots being flexible and distortable and projecting outwardly beyond adjacent portions, means within the tubular member for retracting the forward end thereof with respect to the rearward end to flex said portions further outwardly, said means comprising a flexible member anchored at one end to the forward end of the tubular member, and means carried by the flexible member and adapted to engage the tubular member for releasably retaining the forward end of the tubular member in retracted 7 position.
