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 method of loading a self-expanding stent onto a delivery guide, the method comprising:
-
holding the stent compressed in a reduced diameter configuration in at least one sleeve member;
engaging the stent with the delivery guide; and
twisting the stent while in the sleeve member. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A method of securing a mesh stent on a delivery guide, the method comprising:
-
twisting a first end of the mesh, lattice or woven stent relative to a second end of the mesh stent to reduce a diameter of the stent; and
releasably securing by at least one electrolytic latch a plurality of projections on each end of the stent to a delivery guide.

62. A stent delivery system made by a process comprising the acts of:
-
holding a stent compressed in a reduced diameter configuration in at least one sleeve member;
twisting the stent while in the sleeve member engaging the stent with a delivery guide; and
removing the at least one sleeve member from the stent. - View Dependent Claims (63, 64)

65. A stent delivery system made by a process comprising the acts of:
-
providing a stent comprising a near end, a far end and a structure extending therebetween, wherein the structure comprises a mesh, lattice, or woven structure that is able to reduce in diameter upon rotation of the near end relative to the far end;
positioning the stent in a sleeve member;
rotating the near end of the stent relative to the far end of the stent;
mounting the stent to a delivery guide wherein the stent is releasably restrained on the delivery guide.
