Publication number: 20220183708Abstract: 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.Type: ApplicationFiled: November 29, 2021Publication date: June 16, 2022Inventors: Huy PHAN, Hoa NGUYEN, Chi LONG, Todd JENKINS

Publication number: 20210085347Abstract: The present invention provides a catheter for treating occlusions in blood vessels. The catheter includes at least one electrode pair positioned inside of a flexible angioplasty balloon at the distal end of the catheter. In some designs, the electrode pairs are arranged in a low-profile or coplanar configuration, reducing the diameter of the distal end of the device and permitting treatment of tight and hard-to-cross occlusions. The flexible angioplasty balloon has an extremely low profile and does need to be folded before insertion of the catheter into the cardiovascular system. During treatment, the balloon can be expanded a relatively small amount sufficient to immerse the electrode pairs in a conductive fluid before generating shock waves across the electrodes to treat the occlusion. The balloon can be made of material having elastomeric properties such that it returns to its original low profile configuration when it is deflated following treatment.Type: ApplicationFiled: September 15, 2020Publication date: March 25, 2021Inventors: Huy PHAN, Hoa NGUYEN, Chi LONG, Todd JENKINS
