Abstract
The present invention provides a catheter for treating occlusions in blood vessels. An exemplary catheter for treating occlusions in blood vessels comprises a tubular inner member including a base segment with a first lumen defining a fluid inlet port, and a second lumen defining a fluid outlet port. An extension segment is distal to the base segment. The extension segment has a reduced cross-section. An emitter assembly includes a first insulated wire extending through the second lumen and a second insulated wire, and a conductive sheath wrapped circumferentially around the first insulated wire, the second insulated wire, and the extension segment. A cap or balloon is sealably attached to the distal end of the catheter and surrounds the emitter assembly, said cap or balloon being fillable with conductive fluid.
