Urodynamic catheter and methods of fabrication and use |
摘要 |
A urodynamic catheter incorporating at least one balloon adjacent a distal end thereof and associated with a pressure lumen extending to a proximal end to be placed external to the body of a patient and usable with a transducer housing including a pressure transducer and a mechanism for alternatively venting an air column defined by the assembled pressure lumen and transducer housing to the ambient environment and closing the air column and charging it with air while reducing volume of the air column. One embodiment includes two, separately-chargeable balloons and a bladder fill tube, another embodiment includes a single balloon and a fill tube, and yet another embodiment, suitable for use as a reference catheter to measure abdominal pressure, includes only a single balloon and omits the fill tube. A novel catheter architecture and assembly technique are also disclosed, as are methods of using the inventive catheter.
