Patent Images
1. An implant delivery system comprising:
- an elongated delivery guide having a distal end and a proximal end;
a self-expanding implant mounted on said elongated delivery guide, said implant having a distal end and a proximal end;
a first restraint releasably coupling one of the implant ends to said delivery guide;
a second restraint releasably coupling the other of said implant ends to the delivery guide;
an electrical conductor adapted to be coupled to a power supply and having an erodible section; and
an electrically nonconductive member that connects said first restraint to said electrical conductor, wherein the electrically nonconductive member electrically isolates the electrical conductor and the first restraint from one another, wherein the electrically nonconductive member comprises an elongated non-conductive body having a first end and a second end, wherein the first restraint extends distally from the first end and wherein the electrical conductor extends proximally from the second end.
