Abstract
Abstract A suprapubic catheter is inserted into a bladder in a safe, efficient and simple manner by first inserting a hollow, curved and rigid tubing member transurethrally into a bladder. The tubing member has a catheter therewithin onto which a cutting point is attached, and is constructed in such a manner as to permit the cutting point to, when pushed through the distal end thereof, pierce the anterior wall of the bladder after it has been externally palpated for placement. The cutting point, then emerging from the bladder, can be grasped externally and the catheter can be pulled through the tubing member and into the bladder to a premarked point thereon and may be separated from the main body of the catheter and connection made to a conventional drainage and collection assembly. The tubing member is then withdrawn backwardly leaving the catheter tube safely within the bladder in the proper position. A stylet may be employed to remove the catheter when drainage is to be terminated.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
143 words
A method of placement for a suprapubic catheter comprising: inserting the distal end of a rigid, hollow tubing member having an opening at both ends thereof through the urethra and into the bladder, said distal end being curved; locating the opening on said distal end against the anterior wall of the bladder in the suprapubic region thereof; pushing a cutting point through said tubing member and through said opening on said distal end so as to pierce the anterior wall of the bladder and abdomen in the suprapubic region and through the outer surface of the skin, said cutting point having a catheter attached thereto; pulling said cutting point outwardly away from said tubing member leaving a portion of said catheter within the bladder; and withdrawing said tubing member backwardly from said bladder leaving said catheter at the desired position within said bladder.
Claim 2
Independent Claim
143 words
A method of placement for a suprapubic catheter comprising: inserting the distal end of a rigid, hollow tubing member having an opening at both ends thereof through the urethra and into the bladder, said distal end being curved; locating the opening on said distal end against the anterior wall of the bladder in the suprapubic region thereof; pushing a cutting point through said tubing member and through said opening on said distal end so as to pierce the anterior wall of the bladder and abdomen in the suprapubic region and through the outer surface of the skin, said cutting point having a catheter attached thereto; pulling said cutting point outwardly away from said tubing member leaving a portion of said catheter within the bladder; and withdrawing said tubing member backwardly from said bladder leaving said catheter at the desired position within said bladder.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said bladder is externally palpated prior to locating said opening on said distal end against the anterior wall of said bladder.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein said catheter is withdrawn from the bladder to a predetermined mark on said catheter.
Claim 5
Dependent Claim
27 words
The method of claim 1 wherein said catheter tube has a coiled configuration on the end thereof, and said coiled configuration has a plurality of openings thereon.
Claim 6
Dependent Claim
32 words
The method of claim 1 wherein said cutting point is pushed through said distal end of said tubing member by means of a rigid plunger in telescopic relationship with said tubing member.
Claim 7
Dependent Claim
32 words
The method of claim 5 wherein said plunger is hollow and open at at least one end thereof, and said catheter is contained therein prior to insertion into the bladder and abdomen.
Claim 8
Independent Claim
115 words
A device for inserting a suprapubic catheter comprising: a rigid, hollow, tubing member having a curved distal end portion thereon, said tubing member having an opening at both ends thereof; a rigid, hollow, metal plunger tube open at at least one end thereof, in which a catheter tube may fit within, is disposed telescopically within said tubing member for pushing a cutting point disposed within said tube outwardly through said distal end portion, said plunger tube has a ringed configuration on the proximal end thereof for holding and guiding said plunging means and for convolutely Storing said catheter tube therearound prior to insertion into a bladder, said cutting point having said catheter tube attached thereto.
Claim 9
Independent Claim
115 words
A device for inserting a suprapubic catheter comprising: a rigid, hollow, tubing member having a curved distal end portion thereon, said tubing member having an opening at both ends thereof; a rigid, hollow, metal plunger tube open at at least one end thereof, in which a catheter tube may fit within, is disposed telescopically within said tubing member for pushing a cutting point disposed within said tube outwardly through said distal end portion, said plunger tube has a ringed configuration on the proximal end thereof for holding and guiding said plunging means and for convolutely Storing said catheter tube therearound prior to insertion into a bladder, said cutting point having said catheter tube attached thereto.
Claim 10
Dependent Claim
14 words
The device of claim 7 wherein said plunger tube is open at both ends.
Claim 11
Dependent Claim
17 words
The device of claim 8 wherein said plunger tube and said tubing member are of a metal.
Claim 12
Dependent Claim
19 words
The device of claim 8 wherein said plunging means and said tubing member are of a reinforced plastic material.
Claim 13
Dependent Claim
27 words
The device of claim 10 wherein said tubing member has a pair of flanging rings on the proximal end thereof for holding and guiding said tubing member.
Claim 14
Dependent Claim
32 words
The device of claim 7 wherein said catheter tube has a coiled configuration on the end thereof for retaining said tube intracystically, and said coiled configuration has a plurality of openings thereon.
Claim 15
Dependent Claim
23 words
The device of claim 12 wherein said catheter tube is marked to show the proper level for positioning said tube within the bladder.
Claim 16
Dependent Claim
36 words
The device of claim 13 wherein said mark on said tube is a shouldered portion that also serves as an engaging means for enabling said plunger tube to push said catheter out of said tubing member.
Claim 17
Dependent Claim
15 words
The device of claim 13 wherein said cutting point is a beveled, three-sided, electropolished needle.
Claim 18
Independent Claim
138 words
A device for inserting a suprapubic catheter comprising: a rigid, hollow, metal tubing member having a curved distal end portion thereon, said tubing member having an opening at both ends thereof, and having a pair of flanging rings on the proximal end thereof; and, a rigid, hollow, metal plunger tube, being open at at least one end thereof, and having a ringed configuration on the proximal end thereof, disposed telescopically within said tubing member for pushing a cutting point disposed within said tubing member outwardly through said distal end portion thereof, said cutting point being a beveled, three-sided, electropolished needle and having a catheter tube attached thereto, said tube having a coiled configuration on the end thereof and a plurality of openings thereon, and said tube has a mark thereon for properly positioning said tube within the bladder.
Claim 19
Independent Claim
138 words
