32. A method for implanting a prosthetic valve in a patient, comprising:
-
providing a prosthetic valve system comprising a prosthetic valve having a first helical pre-implantation configuration that is reversibly transformable to a second valvular configuration, a radially or helically collapsible and expandable crown, the crown including a cylindrical support means for enclosing said prosthetic valve, and an elongate delivery apparatus; mounting said prosthetic valve at the first pre-implantation configuration and said crown at a collapsed configuration onto said delivery apparatus; delivering said delivery apparatus to a target implant site in the patient; expanding said crown at the implant site; deploying said prosthetic valve at the implant site by transforming said prosthetic valve from the first pre-implantation configuration to the second valvular configuration; and removing the delivery apparatus from the patient. - View Dependent Claims (33, 34)

35. A method of delivering at least one bioactive agent to a body channel of a patient, comprising:
-
providing an implant device loaded with said at least one bioactive agent, wherein said implant device is at a first helical pre-implantation configuration and a second circular configuration, wherein said first configuration is reversibly transformable to said second configuration; delivering said implant device to about said body channel at said first configuration; deploying said implant device at said body channel by transforming the implant device to said second configuration; and releasing said at least one bioactive agent. - View Dependent Claims (36, 37, 38)
