Abstract:
1. An assembly comprising a medical device and a retrieval catheter for use in retrieving the medical device from within a body vessel, the retrieval catheter comprising: a distal tip having a wall with an inner surface and an outer surface, the wall having a distal end and a proximal end, the inner surface defining a lumen, the wall tapering inwardly in a distal direction toward a central longitudinal axis defined by the retrieval catheter such that a distance defined between the inner surface of the wall and the central longitudinal axis decreases in the distal direction absent any external forces; and the lumen having a diameter at the distal end that is less than a diameter of the medical device, the wall having an undeflected configuration prior to retrieval of the medical device into the lumen, a deflected configuration during retrieval of the medical device into the lumen and the wall returning to the undeflected configuration after complete retrieval of the medical device into the lumen, the distal end being rolled inwardly in the deflected configuration such that the distal end of the wall faces into the lumen, and at least a portion of the outer surface of the distal tip being radially expanded in the deflected configuration.
