Abstract
An implant delivery system is disclosed. The delivery system includes an elongated member having an implant mounting location. A self-expandable implant is mounted at the implant mounting location. The implant is held in a compressed orientation by a retractable sheath. An interlock structure prevents the implant from deploying prematurely as the sheath is retracted.

40. A method for deploying a self-expandable implant with a deployment system, the deployment system including a sheath for holding the implant in a compressed orientation, the implant including first and second ends, the implant also including an interlock surface positioned between inner and outer diameters of the implant, the interlock surface being located within 5 millimeters of the first end of the implant, the method comprising:

generating relative movement between the implant and the sheath to expose the implant;
engaging the interlock surface with a retainer as the implant is exposed to prevent the implant from prematurely exiting the sheath; and
after the implant has been exposed beyond the interlock surface, disengaging the interlock surface from the retainer by self-expanding the implant, wherein the interlock surface disengages from the retainer simultaneous with the expansion of a cell defining portion of the implant. - View Dependent Claims (41, 42, 43)
