Abstract
The present invention provides a device and method for retrieving a balloon expandable stent which has been misplaced. It utilizes a balloon catheter which is sized to fit into the inside diameter of a stent to be retrieved. The stent has proximal and distal ends and a predefined expansion force threshold which must be exceeded in order to radially expand the stent. The balloon has proximal and distal ends, a greater axial length than the stent to be retrieved, and is made of a compliant material which will deform at less than the predefined expansion force threshold of the stent.
