What changed

USPTO published patent application US20260090755A1 for an amplifier interface system in cardiac catheter procedures. The invention discloses a multi-electrode catheter system where an amplifier interface connects a first quantity of amplifier channels to a larger second quantity of catheter channels through a switching matrix. This matrix enables selective electrical coupling of a subset of catheter channels to available interface channels. The application classifies under A61B (diagnosis/surgery) with focus on cardiac mapping and ablation applications.

Medical device manufacturers developing cardiac mapping or ablation systems should review the patent claims for potential licensing or design-around considerations. The switching matrix architecture may be relevant to any multi-electrode electrophysiology system requiring flexible channel allocation. No compliance obligations arise from this publication.

Abstract

Disclosed herein is a multi-electrode catheter system including an amplifier stage and an amplifier interface. The amplifier stage includes at least a first quantity of amplifier channels. The amplifier interface includes a first interface having at least the first quantity of interface channels. The amplifier channels are respectively electrically coupled to the interface channels. The amplifier interface includes a second interface having a second quantity of catheter channels, the second quantity being greater than the first quantity. The catheter channels are configured to be respectively electrically coupled to corresponding electrode leads of a multi-electrode catheter. The amplifier interface includes a switching matrix electrically coupled between the first interface and the second interface. The switching matrix is configured to selectively electrically couple a selected subset of catheter channels to respective interface channels of the first quantity of interface channels.
