International ClassesA61F 002/06A61B 017/00 AbstractDisclosed is a retrievable elastomeric stent, an apparatus for the insertion/retrieval of the stent and a method for insertion/retrieving the stent. The removable stent includes at least one proximal and at least one distal engagement element to allow the insertion/retrieval catheter to engage the stent for the application of axial force. The insertion/retrieval catheter includes a tubular body and an axially moveable guidewire, each adapted to engage the engagement elements of the tubular stent. When elongated in an axial direction, the stent is reduced in cross-sectional area. The stent can then be removed directly, or can fit within the tubular body of the extraction catheter for atraumatic removal from the treatment location. Further disclosed are configurations of the engagement elements to allow more precise manipulation of body lumen stents. | |
