摘要：
Devices and methods for retrieving percutaneously implanted catheter systems such as a heart valve repair system. The devices include at least one locking connector at the distal end of a flexible elongated extension for coupling to an implanted tubular member. The locking connector may be a tubular anchor having a pair of distal prongs which are biased outward and face in a proximal direction, as well as an expandable auxetic midsection. Inserting the tubular anchor into the implanted tubular member flexes the distal prongs inward such that they prevent proximal movement of the tubular anchor. A user pulls on the proximal end of the tubular anchor to expand the auxetic midsection and lock the two pieces together. The devices and methods are particularly useful to attach extensions to implanted concentric tubes to enable relative axial force application.
