Pass-through restraint electrolytic implant delivery systems

摘要

Medical devices and methods for delivery or implantation of prostheses within hollow body organs and vessels or other luminal anatomy are disclosed. The subject technologies may be used in the treatment of atherosclerosis in stenting procedures or be used in variety of other procedures. The systems may employ a self expanding stent restrained by one or more members released by an electrolytically erodable latch. Such release means do not connect directly to the implant, though one or more portions may contact it.

主权项

1. A stent delivery system comprising:
an elongate body; a stent comprising a near end, a far end and a structure extending therebetween; and an electrically conductive segment of material passing through at least one of the near end and the far end of the stent and connecting said at least one of the near or far end of the stent to the elongate body, the electrically conductive segment comprising at least one electrolytically erodible section being spaced longitudinally away from and not directly connected to the stent and being in non-overlapping relation with the stent, wherein erosion of said erodible section allows the electrically conductive segment of material to be pulled through the structure to completely release said stent end from the elongate body without releasing the other stent end, wherein the stent includes a receptacle and the electrically conductive segment of material is in the form of a loop which passes through the receptacle.
