Abstract: An apparatus for monitoring a nerve includes a Foley type catheter having an exterior surface, and first and second pairs of ring electrodes formed on the exterior surface of the Foley catheter. Each of the first and second pairs of ring electrodes is configured to perform at least one of stimulating the nerve and recording nerve activity.

Abstract: One or more markers or sensors are positioned in the vasculature of a patient to facilitate determining the location, configuration, and/or orientation of a vessel or certain aspects thereof (e.g., a branch vessel), determining the location, configuration and/or orientation of a endovascular devices prior to and during prosthesis deployment as well as the relative position of portions of the vasculature and devices, generating an image of a virtual model of a portion of one or more vessels (e.g., branch vessels) or devices, and/or formation of one or more openings in a tubular prosthesis in situ to allow branch vessel perfusion when the prosthesis is placed over one or more branch vessels in a patient (e.g., when an aortic abdominal artery stent-graft is fixed to the aorta superior to the renal artery ostia).

Abstract: A method of diagnosing and treating a patient having erectile dysfunction by placement of a stent or paving material within a stenosed region of a pelvic vessel. The diagnosing of the patient's condition includes determining if a treatable stenosis exists within a pelvic vessel and if proper blood flow is otherwise occurring within the penile arteries.

Abstract: The invention provides a system and method for treating a vascular condition. The system comprises a guide catheter that includes a central lumen. A stent delivery device that includes a delivery catheter and a stent disposed on the delivery catheter is slidably received in the central lumen. A stop interface retains a portion of the delivery catheter within the central lumen while still allowing positioning of the stent beyond a distal end of the guide catheter. In use, the guide catheter with the retained stent delivery device is introduced into a vessel. The stent carried on the stent delivery device is expanded after being positioned at a location beyond a distal end of the guide catheter.
