Abstract
Abstract A method of and an instrument for inserting a suprapubic catheter. The instrument comprises a tube having a curved distal portion insertable through the urethra into the bladder to bring the distal end of the tube in engagement with the wall of the bladder in register with the suprapubic area of the abdominal wall. After inflating the bladder with a suitable fluid through the tube and a lateral opening in the curved distal portion thereof, an incision is made through the abdominal wall and the wall of the bladder in register with the distal end of the instrument, which then emerges outwardly through the incision.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A method of inserting a suprapubic catheter, characterized by the use of an instrument having a curved distal portion terminating in a tubular distal end provided with a removable closure, and including the steps of: a. inserting the distal end of the instrument through the urethra into the bladder and into engagement with the anterior wall of the bladder in register with the suprapubic area of the abdominal wall; b. making an incision through the abdominal wall and the anterior wall of the bladder in register with the distal end of the instrument; c. displacing the distal end of the instrument outwardly through the incision; d. removing the closure from the distal end of the instrument; e. inserting a portion of the catheter into the distal end of the instrument; f. displacing the distal end of the instrument and a portion of the catheter into the bladder through the incision; and g. withdrawing the instrument from the bladder and the urethra, leaving a portion of the catheter within the bladder.
Claim 2
Independent Claim
170 words
A method of inserting a suprapubic catheter, characterized by the use of an instrument having a curved distal portion terminating in a tubular distal end provided with a removable closure, and including the steps of: a. inserting the distal end of the instrument through the urethra into the bladder and into engagement with the anterior wall of the bladder in register with the suprapubic area of the abdominal wall; b. making an incision through the abdominal wall and the anterior wall of the bladder in register with the distal end of the instrument; c. displacing the distal end of the instrument outwardly through the incision; d. removing the closure from the distal end of the instrument; e. inserting a portion of the catheter into the distal end of the instrument; f. displacing the distal end of the instrument and a portion of the catheter into the bladder through the incision; and g. withdrawing the instrument from the bladder and the urethra, leaving a portion of the catheter within the bladder.
Claim 3
Dependent Claim
48 words
A method as set forth in claim 1 wherein the instrument is a tube provided with a lateral opening therein adjacent its distal end, and including the additional step of inflating the bladder with a fluid through the tube and the lateral opening prior to making the incision.
Claim 4
Dependent Claim
40 words
A method as defined in claim 1 including the additional step of inserting a catheter probe into the catheter prior to displacing the distal end of the instrument and said part of the catheter into the bladder through the incision.
Claim 5
Dependent Claim
26 words
A method according to claim 1 wherein the catheter is a Foley catheter, and including the additional step of inflating the Foley catheter within the bladder.
Claim 6
Independent Claim
187 words
A method of inserting a suprapubic catheter into the bladder, characterized by the use of an instrument having a curved distal portion terminating in a distal end, and including the steps of: a. inserting the distal end of the instrument through the urethra into the bladder and into engagement with the anterior wall of the bladder in register with the suprapubic area of the abdominal wall; b. making an incision through the abdominal wall and the anterior wall of the bladder in register with the distal end of the instrument; c. displacing the distal end of the instrument outwardly through the incision; d. connecting a portion of the catheter to the distal end of the instrument; e. displacing the distal end of the instrument and a part of the catheter into the bladder through the incision; f. disengaging the distal end of the instrument from said portion of the catheter entirely within the bladder, without displacing any element of the catheter from the bladder into the urethra; and g. withdrawing the instrument from the bladder and the urethra, leaving said part of the catheter within the bladder.
Claim 7
Independent Claim
187 words
A method of inserting a suprapubic catheter into the bladder, characterized by the use of an instrument having a curved distal portion terminating in a distal end, and including the steps of: a. inserting the distal end of the instrument through the urethra into the bladder and into engagement with the anterior wall of the bladder in register with the suprapubic area of the abdominal wall; b. making an incision through the abdominal wall and the anterior wall of the bladder in register with the distal end of the instrument; c. displacing the distal end of the instrument outwardly through the incision; d. connecting a portion of the catheter to the distal end of the instrument; e. displacing the distal end of the instrument and a part of the catheter into the bladder through the incision; f. disengaging the distal end of the instrument from said portion of the catheter entirely within the bladder, without displacing any element of the catheter from the bladder into the urethra; and g. withdrawing the instrument from the bladder and the urethra, leaving said part of the catheter within the bladder.
