Abstract: A catheter system is disclosed including an elongated catheter, an elongated balloon carrier and a disposable balloon formed from an expandable and resilent biocompatible material. The balloon has a lumen disposed between a proximal end and a distal end thereof. The proximal end of the carrier and the distal end of the catheter are configured to permit the distal end of the catheter to matingly engage the proximal end of the carrier. The outer diameter of the balloon carrier and the outer diameter of the balloon are configured such that the diameter of the carrier and the diameter of the balloon permit the balloon first to be slideably mounted onto the balloon carrier and second to be slideably moved from the carrier onto the catheter when the proximal end of the carrier is matingly or otherwise suitably engaged with the distal end of the catheter.

Abstract: An open circuit gravity-assisted uroflowmeter has a urine collector having a generally open inlet in fluid communication with a sensing passage located at a lower elevation than the inlet, the sensing passage intersecting a magnetic field and having electrodes for detecting a flow-dependent voltage induced by the passage of urine through the magnetic field. Preferred embodiments of the uroflowmeter may have low pressure drop, rapid response and simple construction.

Abstract: In general, the invention is directed to a balloon catheter system for intra-luminal or intra-cavity pressure measurements. In accordance with the invention, the balloon catheter system provides a closed fluid charging mechanism to charge and discharge a balloon mounted on the catheter. More particularly, the charging mechanism may include a closed reservoir, a passage, and an actuator that acts to drive fluid out of the reservoir and through the passage. A lumen within a catheter may transport fluid from the passage to charge the balloon. The pressure monitoring catheter system may take pressure measurements when the balloon is charged. Discharging the balloon may include withdrawing the actuator from the charging mechanism, which fills the reservoir with fluid from the balloon. In addition, a seal member may be used in the pressure monitoring catheter system to provide a more sealed environment for holding and transporting fluid.

Abstract: A disposable balloon catheter and corresponding catheter system are disclosed. In one embodiment, the catheter system comprises several components, such as: (a) an elongated catheter comprising a first outer diameter, a first proximal end and a first distal end; (b) an elongated balloon carrier having a second proximal end, a second distal end and a second outer diameter, the second proximal end of the carrier and the first distal end of the catheter being configured to permit the first distal end of the catheter to matingly engage the second proximal end of the carrier, the second outer diameter of the balloon carrier being similar to the first outer diameter of the catheter; and (c) a disposable balloon formed from an expandable and resilient biocompatible material, the balloon having a lumen disposed between a third proximal end and a third distal end thereof, the lumen having at least a third inside diameter.
