ABSTRACT:
Disclosed is a removable cardiovascular stent, an apparatus for the retrieval of the stent and a method for removal of the stent. The removable stent includes radially inwardly extending engagement members for contacting an extraction catheter. The extraction catheter includes a tubular body and an axially moveable guidewire, each adapted to grasp the engagement members of the tubular stent. The stent is elongated in an axial direction thereby reducing the cross-sectional area of the stent. The stent can be removed directly, or can fit within the tubular body of the extraction catheter for atraumatic removal from the treatment location.
