Aspiration lithotripsy device

A medical device for treating a thrombotic lesion, comprising:

• an elongate catheter including a proximal end region, a distal end region, an aspiration lumen and a wire lumen extending therein;
• a support shaft coupled to the elongate catheter, wherein the support shaft includes a support lumen and a distal end coupled to a first reflector and a second reflector;
• an electrically conductive member extending within a portion of the wire lumen, wherein the conductive member includes a first end region positioned adjacent to the first reflector and a second end region positioned adjacent to the second reflector;
• a first emitter coupled to the first end region of the conductive member, the first emitter positioned adjacent to the first reflector;
• a second emitter coupled to the second end region of the conductive member, the second emitter positioned adjacent to the second reflector;
• wherein the first emitter and the second emitter are configured to discharge an electrical pulse directed toward the distal end region of the elongate catheter.

A medical device system for treating a thrombotic lesion, comprising:

• a console including a pump and an arc discharge generator;
• a controller coupled to the console;
• an elongate catheter including a proximal end region, a distal end region, an aspiration lumen and a wire lumen extending therein, wherein the proximal end region coupled to the console;
• a support shaft coupled to the elongate catheter, wherein the support shaft includes a support lumen and a distal end coupled to a reflector;
• an electrically conductive member extending along the elongate catheter, wherein the conductive member includes a proximal end region and a distal end region positioned adjacent to the reflector, and wherein the proximal end region is coupled to the controller;
• an emitter coupled to the distal end region of the conductive member;
• wherein the emitter is configured to discharge an electrical pulse directed toward the distal end region of the elongate catheter.
