Abstract
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.

39. A stent delivery system comprising:
-
an elongate body having at least one of a near seat and a far seat, and a stent comprising a near end, a far end and a structure extending therebetween, the stent further comprising at least one of a near and far mating portions, wherein each stent mating portion is received within in an elongate body seat, and wherein at least one of the near seat and the far seats underlies a cover comprising at least one electrolytically releasable section for at least partially opening the cover. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A method of loading a self-expanding stent onto a delivery guide, the method comprising:
-
fitting a portion of at least one of near and far mating portions of the stent within a seat of a delivery guide; and
at least partially covering at least one of the near and far mating portions with an electrolytically releasable member to secure the stent to the delivery guide. - View Dependent Claims (55, 56, 57, 58, 59)

60. A stent delivery system made by a process comprising the acts of:
-
mounting a stent to a delivery guide by releasably engaging a stent mating portion with a. delivery guide seat; and
at least partially covering at least one of the near and the far delivery guide seat with a cover comprising at least one electrolytically releasable section for at least partially releasably restraining the stent on the delivery guide. - View Dependent Claims (61, 62, 63, 64, 65)

66. A method for deploying a self-expanding stent, the method comprising:
-
introducing a delivery guide having a stent secured in a reduced diameter configuration thereon at least partially by a cover having at least one electrolytically releasable portion;
applying a voltage to release the cover to erode the releasable portion and release the stent.
