ABSTRACT:
A stent delivery system, and methods of use, are provided in which a stent is constrained in a contracted delivery state with binding straps that are electrolytically eroded to deploy the stent. The binding straps are attached to a power source and each have a small electrically uninsulated reduced thickness portion. A second electrode wire is disposed adjacent to the uninsulated areas or separately electrically coupled to an exterior surface of the patient's body. When an electric current is applied, the uninsulated areas of the binding straps are electrolytically eroded and rupture, thereby allowing the stent to at least partially deploy.
