Abstract
A stent delivery system comprising a stent and at least one tether detachably connected to the stent by a connecting member. In one embodiment, the tether may comprise a conductive material and the connecting member may comprise a material subject to degradation upon application of an electrical current. In another embodiment, the connecting member, the stent, and the tether each may have a mechanical strength, where the strength of the connecting member is less than the strength of the stent and the tether. In yet another embodiment, application of electrical current may weaken the connecting member sufficient to enable detachment of the tether. A method of deploying a stent uses the stent delivery device comprising a tether attached to the stent by a connecting member. The tether may be used for accurate positioning of the stent.
