Inverting capture apparatuses having material depots

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.
