Shockwave Medical Patent Application for Shock Wave Catheter to Facilitate Pacemaker Lead Removal
Summary
Shockwave Medical, Inc. has filed a patent application (US20260108728A1) for a shock wave catheter system designed to facilitate pacemaker lead removal. The system uses a catheter with a nozzle sized to receive a pacemaker lead, with shock wave emitters positioned to generate waves that disrupt lesions and assist in lead extraction. The application was filed on October 20, 2025, and published on April 23, 2026. Inventors include Alyssa McCullough, Robert Zelenka, Daryl Wong, Thu Anh Ho, and Steven Yihlih Peng.
About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
Shockwave Medical, Inc. has published a patent application (US20260108728A1) for a catheter-based system that uses directed shock waves to facilitate pacemaker lead removal. The invention describes advancing a catheter over a pacemaker lead, positioning a nozzle outlet adjacent to a lesion, and generating shock waves that propagate distally within the nozzle and are concentrated to disrupt the lesion.
This published application represents a new intellectual property filing in the cardiac rhythm management space. Competitors developing similar catheter-based lead extraction technologies should review the application's claims for potential overlap with their own R&D programs.

Abstract
A method of facilitating pacemaker lead removal using a shock wave catheter includes: advancing a catheter over a pacemaker lead, the catheter comprising a nozzle comprising an outlet sized to receive the pacemaker lead, and at least one shock wave emitter positioned proximally of the nozzle outlet; positioning the nozzle outlet adjacent to a treatment site comprising a lesion located at least partially distal to the nozzle outlet; generating one or more shock waves that propagate distally within the nozzle and are concentrated by the nozzle to disrupt the lesion to facilitate removal of the pacemaker lead.
