CONFIGURATION AND METHOD FOR FIXATION OF A FILTER TO A CATHETER

摘要

An attachment configuration for a vascular filter assembly including a self-expanding filter member attached to a catheter body and constrained from expansion in a first configuration by a constraining sheath is presented. The attachment configuration includes an outer tube of material that is overlaid over an end of the filter member and bonded to the catheter body through cutouts disposed through the end of the filter member.

1. A medical device coupled to a catheter, comprising:
a. a generally tubular coupling projecting proximally from the medical device and circumferentially engaged with the catheter, the tubular coupling further comprising a plurality of cutouts positioned along a longitudinal axis of the tubular coupling and about a circumferential axis of the tubular coupling, the plurality of cutouts being geometrically deformable to allow for diametric expansion diametric compression of the tubular coupling; and b. a circumferentially compressive member disposed concentrically about the generally tubular member and over the plurality of cutouts, and engaged with the generally tubular member and the catheter.
