INFLATABLE RETENTION CATHETER Filed April 10. 1958 'IIIIIIII. VIII INVENTOR. FRANK J, KEOUGH BY I JMMWJVM ATTORNEY United States Patent INFLATABLE RETENTION CATHETER Frank J. Keougli, Pawtucket, RI.
Application April 10, 1958, Serial No. 727,690
'5.Claims. (Cl. 1-28349) This invention relates to catheters, and more particularly'to inflatable retention catheters which are employed in various urological procedures, such as drainage of the bladder.
A primary object of this invention is to provide a retention type catheter with improved'features of construction to increase the efliciency of the catheter and reduce pain and discomfort to the patient.
Another o'bjectofthe :present invention is to provide an inflatable retention catheter which may be readily introduced into a body cavity, be maintained in the cavity for an extended period of time without fear of clogging or accidental dislodgement and be subsequently removed fromth'e body cavity, without :undue pain or discomfort to the patient.
In urological procedures, such as artificial drainage of the bladder by means of the catheter, the surgeon frequently encounters scar tissue. This scar tissue .is less resilient than normal tissue and therefore provides resistance to the proper acceptance of a'icatheter, resulting in faulty drainage.
The membranes through which the catheter .passes are delicate and sensitive to the acceptance of :foreign bodies such a's-c'atheters.
'It therefore behooves the manufacturers of catheters to provide -a catheter of the smallest possible diameter for easy insertion and to lessen the :degree of resistance and consequent irritation to the body'mem'branes while providing a catheter which can be :expanded uniformly and to a maximumdiameterto insure'proper drainage.
In "the past inflatable catheters were provided with a single fluid passageway to inflate'the retaining bulb. The catheters themselves were semi-rigid and were provided in varying sizes to accommodate the passageway through which they passed. The single fluid passageway had no effect on expanding the catheter body it merelystraightened the 'body. The result was thatthe body of the catheter very closely approximated the diameter of the passageway through which it passed. If the single passageway became clogged the patient not infrequently died. The catheter could not accommodatescarntissue through circumferential expansion. The catheter was painful to the patient because a large diameter body'was necessary to 'fill out the passageway.
The present invention obviates thesedifliculties by providing a new and novel construction.
Referring to the drawings in which similar characters of reference indicate corresponding'parts in all the figures:
2,912,981 7 'Paiftented Nov. 17, 1953 ICC meral 10 and comprises an extremely thin walled elongated, flexible .
tubularmember12, that is fabricated from a suitable material such as natural or artificial rubber or molded or extruded plastic material or dipped tubing or a combination of a polyvinyl resin such as copolymer of vinyl chloride and vinyl acetate orpolyethylene-coated with latex either by spraying or dipping. The flexible
tubular member12 is substantially concentric or circular intransverse.cross section. A concentricaxial
longitudinal passageway14 defines a drainagechannel or lumen.
Tubular member12 .is closed and rounded atitsforward
end16 to facilitate insertion into a body cavity and .is open at its
rearward end18. Adjacent theforward eud '16 of
tubular member12 is a plurality of
openings20 for permitting body fluids, such as urine in the bladder, to flow into
passageway14 when the catheter :10 is in position.
.Aplurality of elongated
fluted grooves21 areprovided in the butside diameter of flexible
tubular member12.
Grooves21 may be either parallel or spiral shaped. .A second-extremely thin walled elongated, flexible tubular member 11 is provided and .is fabricated from vthe same material used to make flexible
tubular member12. Flexible tubular member 11 is shorter in length than the length of
grooves21. Member :11 is positioned over flexible
tubular member12 in telescopic relationshipwith grooves '21 extending beyond either end of member 1 1. Member 11 and member 12'are hermetically sealed together.
A distension-duct collar generally indicated at 13 is hermetically sealed on oneendto flexible tubularmember 1-2 as at 15 and is hermetically sealed on theother en'd to flexible tubular member 11 .as at .17. A :
cavity19 is provided between said ends with a'conduit 24 forming an integral part of
collar13. Conduit-24 is incommunication with
cavity19 and
grooves21. v
:Rearward-of
openings20 is an inflatable bag .26 hermetically sealed on opposite ends to flexible tubular member 11 and flexible tubular member-12, respectively.
Inflatable bag :26 ispreferably fabricated-of rubber which has great and sensitive'expansible qualities.
Grooves21 establish-communication betweenconduit 24 and the interior of
bag26.
For the purpose of outlining the manner of using catheterltl, it is first assumed that the partsare in the relative position shown in Figure 4, and that the rear end of-conduit 2'4 isopen to theatmosphere.
Bag26 is manually Figure 2 is a "horizontal cross sectional view taken collapsed .and .deflated and arranged so that it -'lies su'b stantially parallel to the outside diameter of flexible tubular member 11.
Catheter10 may be greased as with Vaseline, mineral oil or other membrane lubricant. Closed
end16 of flexible
tubular member12 is theninserted in the urethra and the catheter is advanced through the'urethra until the forward portion of the tubular member-and all of
bag26 have been introduced'into the bladder and lie forwardly of its vesical orifice. A suflicient amount of air or other fluid may next be introduced into "
bag26 by
wayof conduit24,
cavity19 and'
grooves21;to' partially inflate
bag26.
Catheter10 is then retracted through the urethra until the end of
bag26 away from
end16 of
member12 bears against the anterior and posterior lips of the vesical orifice to properly position the catheter. Additional air-or fluid under pressure *is' supplied to
bag26 by way of
conduit24, cavity 19'and grooves '21 until -
bag26 is fully inflated, as shown in Figures 1 and 2. The"free end of
conduit24 is closed by a suitable plug or :the like to prevent e'scapeo'f air or fluid from
bag26 and consequent deflation of the same.
With
bag26 located and inflated as described, the same ensures retention of the catheter in the bladder. In other words,
bag26 prevents accidental dislodgment or removal of the catheter from the bladder, and the bladder is drained by way of
openings20 and axial
longitudinal passageway14.
To remove the catheter from the bladder, the rear end of
conduit24 is opened to the atmosphere, permitting discharge of air of fluid from
bag26, and resulting in collapse of
bag26. Catheter is then slowly retracted and completely withdrawn from the bladder and the urethra.
It has been found that fabricating flexible
tubular members11 and 12 from plastic material permits the walls of
members11 and 12 to be extremely thin thereby permitting greater drainage for a given diameter of
tubular members11 and 12. Conversely, a much smaller set of
tubular members11 and 12 may be employed to allow the insertion of
catheter10 into scar tissue and otherwise damaged urethra or a urethra of very small size. The plastic is impervious to urinary salts and is chemically inert and acid resistant.
Molded or extruded plastic tubular member may be fabricated in substantially concentric cross sectional area, thus insuring perfect drainage by eliminating leakage around a catheter which is out of round in cross sectional diameter. Catheters with a single inflating duct or
groove21 had a wall which projected into the
drainage passageway14 which reduced the effective drainage area. The single duct could clog. The likelihood of a plurality of ducts or grooves clogging is greatly minimized. A clogged duct could mean death to a patient. The plurality of ducts or
grooves21 insures a uniform and expanded tubular member 11 which in turn insures leak proof engagement with the urethra.
10 may be dipped or sprayed with a very thin filament of latex for certain types of drainage use.
Having shown and described preferred embodiments of the present invention, by way of example, it should be realized that structural changes could be made and other examples given without departing from either the spirit or scope of this invention.
