Abstract
A device and method for retrieving a stent from the vessel of a patient includes a catheter which is formed with a central lumen that defines a passageway having a diameter. A deformable distal tip is attached to the catheter to establish an extension of the passageway. In the operation of the device, the distal tip is initially maintained in a first configuration wherein the stent can be received into and through the passageway. While the distal tip is maintained in this first configuration, a portion of the stent to be retrieved is withdrawn into the passageway of the distal tip. The distal tip is then distended or deformed into a second configuration wherein the diameter of the passageway is reduced to grip the stent. The catheter and the gripped stent are then retrieved from the vessel of the patient.
