System and method for assessing urinary function
First Claim
1. A system for assessing urinary function comprising:
- a processor;
a tubing assembly forming a first fluid conduit between a first fluid inlet and a first fluid outlet;
an insert member having a channel therethrough and coupled to the first fluid outlet so that fluid flowing through the first fluid conduit may flow through the insert member, the insert member being dimensioned for at least partial insertion into a patient'"'"'s urethral canal distal of the patient'"'"'s urethral sphincter, and being dimensioned so that, when inserted, it substantially blocks fluid flow into or out of the urethral canal other than through the insert member channel;
a fluid delivery device electrically coupled to and controlled by the processor, and coupled to the first fluid conduit for pumping fluid therethrough; and
a detection system for detecting resistance of the urethral sphincter as fluid is infused therein.

Abstract
A system and method for assessing urinary function is provided. The system includes a processor, a tubing assembly forming a first fluid conduit between a first fluid inlet and a first fluid outlet, and an insert member having a channel therethrough and coupled to the first fluid outlet so that fluid flowing through the first fluid conduit may flow through the insert member. The insert member is dimensioned for at least partial insertion into a patient'"'"'s urethral canal distal of the patient'"'"'s urethral sphincter, and dimensioned so that, when inserted, it substantially blocks fluid flow into or out of the urethral canal other than through the insert member channel. The system further includes a fluid delivery device electrically coupled to and controlled by the processor, and coupled to the first fluid conduit for pumping fluid therethrough, and a pressure detection system for detecting pressure within the urethral canal distal of the urethral sphincter and providing information correlating to the detected pressure to the processor. The method includes coupling the test module to the control device, inserting the insert member into a patient, infusing fluid through the insert member until the urethral sphincter opens, and measuring pressure within the urethral canal as fluid is infused therein. Also provided is a test module for coupling to a control device to form a system for assessing urinary function.
