System and method for assessing detrusor instability
First Claim
1. A method for diagnosing detrusor instability comprising the steps of:
- using an insert member having a channel therethrough positioned distal of the urethral sphincter, creating a substantially fluid tight seal to substantially block fluid flow into or out of the urethral canal other than through the channel;
infusing fluid from a fluid source through the channel in the insert member and into the urethral canal at a location distal of the urethral sphincter;
measuring a pressure within the urethral canal at a location distal of the urethral sphincter as the fluid is being infused therein,wherein the infusing step further includes infusing fluid until the urethral sphincter opens, and thereafter until at least one detrusor contraction occurs.

Abstract
A method is provided for diagnosing detrusor instability. The method includes using an insert member having a channel therethrough positioned distal of the urethral sphincter, creating a substantially fluid tight seal to substantially block fluid flow into or out of the urethral canal other than through the channel, infusing fluid from a fluid source through the channel in the insert member and into the urethral canal at a location distal of the urethral sphincter, and measuring a pressure within the urethral canal at a location distal of the urethral sphincter as the fluid is being infused therein. The infusing step further involves infusing fluid until the urethral sphincter opens, and thereafter until at least one detrusor contraction occurs.

10. A method for diagnosing detrusor instability comprising the steps of:
-
coupling a test module to a control device, the test module including a tubing assembly having a first fluid conduit between a first fluid inlet and a first fluid outlet, and an insert member coupled to the first fluid outlet and having a channel therethrough in communication with the first fluid conduit so that fluid flowing through the first fluid conduit can flow through the insert member; coupling the first fluid inlet to a fluid source; inserting the insert member at least partially into a patient'"'"'s urethral canal at a location distal of the urethral sphincter so as to substantially block fluid flow into or out of the urethral canal other than through the insert member channel; infusing fluid from the fluid source into the urethral canal through the first fluid conduit and insert member; and measuring the pressure within the urethral canal at a location distal of the urethral sphincter as the fluid is being infused therein, wherein, the infusing step further includes infusing fluid into the urethral canal until the urethral sphincter opens, and thereafter until at least one detrusor muscle contraction occurs. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method for diagnosing detrusor instability comprising the steps of:
-
inserting an insert member having a channel therethrough at least partially into a patients urethral canal at a location distal of the urethral sphincter, the insert member being dimensioned to substantially block fluid flow into and out of the urethral canal other than through the insert member channel; infusing fluid from a fluid source through the insert member channel and into the urethral canal at a location distal of the patient'"'"'s urethral sphincter at a rate of approximately 40-120 mL/min; measuring pressure within the urethral canal at a location distal of the urethral sphincter as fluid is being infused therein; and providing data correlating to the measured pressure to a processor; wherein the infusing step further includes infusing fluid until the urethral sphincter opens, and thereafter until at least one detrusor contraction occurs. - View Dependent Claims (17, 18, 19)
