A system for retrieving an implanted medical device includes an outer tubular member and a contractible super-elastic net, which may be joined to an elongate shaft that extends in sliding engagement within the outer tubular member. When the net expands from a contracted condition the net defines a longitudinally extending tubular cavity. An open end of the cavity is sized to receive passage of a housing of the device therethrough； and the net, with the device housing contained therein, forms an interference fit within an inner diameter of the outer tubular member. But, an outer diameter of the net, in a fully expanded condition, is larger than the inner diameter.
