What changed

USPTO issued Patent No. US12588918B2 to Stryker Corporation on March 31, 2026. The patent covers inverting tube apparatuses with material depots for capturing and removing material from body lumens during medical procedures. The depot holds a flexible tube in compressed configuration that inverts over a catheter distal end, designed to release with low force while preventing snagging or binding. The 20 claims were granted for Application No. 17867423.

This patent grant establishes Stryker's intellectual property rights in this medical device technology. Competitors developing similar inverting capture devices for atherectomy, thrombectomy, or similar procedures should review this patent to assess potential freedom-to-operate implications. No immediate compliance action is required, but legal teams should evaluate whether existing or planned products fall within the scope of these claims.

Abstract

Inverting tube apparatuses and methods of using same for removing large amounts of material from a body lumen. The apparatuses and methods described herein may use a depot for holding, in a compressed configuration, a length of the flexible tube configured to invert over the distal end of an inversion support catheter to capture material within a body lumen. The depot is configured to facilitate the release of the flexible tube with a low release force, and in a manner that prevents snagging or binding of the flexible tube either on the body of the catheter or when rolling and inverting into the inversion support catheter.
