Abstract
Abstract An instrument having a curved distal portion insertable through the urethra into the bladder to bring the distal end of the instrument into engagement with the anterior wall of the bladder in register with the suprapubic area of the abdominal wall. After inflating the bladder with a suitable fluid through a longitudinal passage in the instrument and a lateral opening in the curved distal portion thereof, an incision is made through the abdominal wall and the anterior wall of the bladder in register with the distal end of the instrument, which then emerges outwardly through the incision. The distal end of the instrument is provided with a recessed catheter engaging means engageable with a tip portion of a retention catheter and adapted to insert the tip portion of the catheter into the bladder through the incision. Thereafter, the instrument is disengaged from the catheter within the bladder and is then withdrawn from the bladder and the urethra, leaving a portion of the catheter within the bladder. The catheter is then inflated to retain it within the bladder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
An instrument for inserting a suprapubic catheter, said instrument having a curved distal portion terminating in a distal end insertable through the urethra into the bladder and through an incision in the anterior wall of the bladder and the overlying suprapubic area of the abdominal wall to the exterior of the body, said instrument having a longitudinal passage therein from its proximal end toward its distal end and having a lateral opening therein adjacent and communicating with the distal end of said passage, said instrument having catheter engaging means at its distal end engageable with a tip portion of a retention catheter for inserting such tip portion of the catheter through the incision into the bladder, said catheter engaging means being disengageable from the catheter within the bladder, said catheter engaging means being recessed to receive therein at least a part of the tip portion of the catheter, said instrument being a tube from its proximal end to its distal end and being provided with a closure at its distal end, and said tube being closed at a point spaced from the distal end of said instrument and between the distal end of said instrument and said lateral opening.
Claim 2
Dependent Claim
199 words
An instrument for inserting a suprapubic catheter, said instrument having a curved distal portion terminating in a distal end insertable through the urethra into the bladder and through an incision in the anterior wall of the bladder and the overlying suprapubic area of the abdominal wall to the exterior of the body, said instrument having a longitudinal passage therein from its proximal end toward its distal end and having a lateral opening therein adjacent and communicating with the distal end of said passage, said instrument having catheter engaging means at its distal end engageable with a tip portion of a retention catheter for inserting such tip portion of the catheter through the incision into the bladder, said catheter engaging means being disengageable from the catheter within the bladder, said catheter engaging means being recessed to receive therein at least a part of the tip portion of the catheter, said instrument being a tube from its proximal end to its distal end and being provided with a closure at its distal end, and said tube being closed at a point spaced from the distal end of said instrument and between the distal end of said instrument and said lateral opening.
Claim 3
Dependent Claim
276 words
An instrument for inserting a suprapubic catheter, said instrument having a curved distal portion terminating in a distal end insertable through the urethra into the bladder and through an incision in the anterior wall of the blAdder and the overlying suprapubic area of the abdominal wall to the exterior of the body, said instrument having a longitudinal passage therein from its proximal end toward its distal end and having a lateral opening therein adjacent and communicating with the distal end of said passage, said instrument having catheter engaging means at its distal end engageable with a tip portion of a retention catheter for inserting such tip portion of the catheter through the incision into the bladder, said catheter engaging means being disengageable from the catheter within the bladder, said catheter engaging means being recessed to receive therein at least a part of the tip portion of the catheter, said catheter engaging means comprising a hook insertable into a lateral opening in the tip of the catheter, said hook being inclined laterally outwardly and rearwardly toward the proximal end of said instrument, and having its tip spaced laterally from the instrument, so that it can be disengaged from the tip of the catheter within the bladder by a slight movement of said instrument relative to the catheter tip, said catheter engaging means including a longitudinally extending channel into which said hook projects laterally and rearwardly, and a sloping cam surface at the rearward or proximal end of said channel which is engageable by the tip of the catheter in response to a slight movement of said instrument to assist in disengaging said hook from the catheter tip.
Claim 4
Dependent Claim
276 words
An instrument for inserting a suprapubic catheter, said instrument having a curved distal portion terminating in a distal end insertable through the urethra into the bladder and through an incision in the anterior wall of the blAdder and the overlying suprapubic area of the abdominal wall to the exterior of the body, said instrument having a longitudinal passage therein from its proximal end toward its distal end and having a lateral opening therein adjacent and communicating with the distal end of said passage, said instrument having catheter engaging means at its distal end engageable with a tip portion of a retention catheter for inserting such tip portion of the catheter through the incision into the bladder, said catheter engaging means being disengageable from the catheter within the bladder, said catheter engaging means being recessed to receive therein at least a part of the tip portion of the catheter, said catheter engaging means comprising a hook insertable into a lateral opening in the tip of the catheter, said hook being inclined laterally outwardly and rearwardly toward the proximal end of said instrument, and having its tip spaced laterally from the instrument, so that it can be disengaged from the tip of the catheter within the bladder by a slight movement of said instrument relative to the catheter tip, said catheter engaging means including a longitudinally extending channel into which said hook projects laterally and rearwardly, and a sloping cam surface at the rearward or proximal end of said channel which is engageable by the tip of the catheter in response to a slight movement of said instrument to assist in disengaging said hook from the catheter tip.
Claim 5
Dependent Claim
175 words
An instrument for inserting a suprapubic catheter, said instrument having a curved distal portion terminating in a distal end insertable through the urethra into the bladder and through an incision in the anterior wall of the bladder and the overlying suprapubic area of the abdominal wall to the exterior of the body, said instrument having a longitudinal passage therein from its proximal end toward its distal end and having a lateral opening therein adjacent and communicating with the distal end of said passage, said instrument having catheter engaging means at its distal end engageable with a tip portion of a retention catheter for inserting such tip portion of the catheter through the incision into the bladder, said catheter engaging means being disengageable from the catheter within the bladder, said catheter engaging means comprising means for receiving therein and gripping a part of an inflatable portion of the catheter when same is partly inflated, and said receiving and gripping means comprising a socket having an inwardly extending protrusion engageable with the inflatable portion of the catheter.
