1. A method for retrieving an in vivo implanted device having an outer shaft that defines a lumen, comprising:
accessing a proximal end of the outer shaft via a puncture;
advancing at least a distal connector of a co-extensive tubular extension member into the outer shaft, the connector and tubular extension member having an outer diameter small enough to fit within the outer shaft lumen, and wherein the connector comprises a tubular element having an expandable distal anchor and an expandable auxetic section located proximal to the distal anchor;
expanding the distal anchor outward into contact with the outer shaft lumen so as to provide an anchor against relative proximal movement of the connector within the lumen;
subjecting the connector to a tensile force by pulling on a proximal end thereof while holding the outer shaft stationary to cause the auxetic section to radially expand outward into contact with the outer shaft lumen; and
retrieving the implanted device through the puncture.
