Abstract
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.
