Boston Scientific Active Alignment System for Laser Intravascular Lithotripsy
Summary
USPTO issued Patent US12605205B2 to Boston Scientific Scimed, Inc. on April 21, 2026, covering a catheter system with an active alignment mechanism for optimizing optical coupling of a multiplexer in a laser-driven intravascular lithotripsy device. The patent includes 20 claims and names Christopher A. Cook, Gerald D. Bacher, and John F. Black as inventors.
What changed
USPTO granted Patent US12605205B2 to Boston Scientific Scimed, Inc. for an active alignment catheter system used in laser-driven intravascular lithotripsy. The system uses a multiplexer alignment system with a probe light source to scan across light guide proximal ends and determine optimal timing for source beam optical coupling. The patent grants Boston Scientific exclusive rights to this technology in the United States.
Competitors developing intravascular lithotripsy devices with multiplexer-based optical coupling should conduct a freedom-to-operate analysis to assess potential infringement exposure. Legal and IP teams at affected medical device manufacturers should review the patent's claims for scope and evaluate licensing options if applicable.

Abstract
A catheter system (100) for treating a treatment site (106) includes a first light source (124), a plurality of light guides (122A), a multiplexer (128), a multiplexer alignment system (142), and a first beamsplitter (268). The first light source (124) generates a source beam (124A). The multiplexer (128) receives the source beam (124A), and alternatively directs the source beam (124A) to each of the plurality of light guides (122A). The multiplexer alignment system (142) is operatively coupled to the multiplexer (128). The multiplexer alignment system (142) includes a second light source (270) that generates a probe source beam (270A) that is directed to scan across a guide proximal end (122P) of each of the plurality of light guides (122A) so that a time is determined to generate the source beam (124A) so that the source beam (124A) is optically coupled to the guide proximal end (122P) of each of the plurality of light guides (122A). The first beamsplitter (268) receives the source beam (124A) and the probe source beam (270A), and alternately directs the probe source beam (270A) and the source beam (124A) toward the guide proximal end (122P) of each of the plurality of light guides (122A).
