Patent ID: 11490844

Abstract:
A catheter for measuring pressure in the urinary tract of a patient includes a catheter body having a proximal and distal end. A plurality of lumens is formed in the catheter body, and an adaptor is coupled to the proximal end of the catheter body. The adaptor includes a port for each lumen. A first pressure sensor, typically including a balloon, is fluidically coupled to a first lumen and is configured and positioned to measure pressure in a urethra of the patient. A second pressure sensor, also typically including a balloon, is fluidically coupled to a second lumen and is configured and positioned on the catheter body to measure pressure in a bladder of the patient. An expandable retention member, which may be coupled to a third lumen, is positioned on the catheter body between the first and second expandable pressure sensors so that the catheter body may be retained at a selected location in the urinary tract to properly position the fluid pressure sensors in the bladder and urethra, respectively.
