First Claim
Patent Images
1. A prosthetic valve for implantation in a patient comprising a first helical pre-implantation configuration and a second functional valvular configuration, wherein said first configuration is reversibly transformable to said second configuration, wherein said valve comprises:
- a support structure with leaflets mounted thereon, said support structure comprising a circular stent and a plurality of elongate support arms, and wherein a first support arm is splittable into two support beams along a longitudinal axis of said first support arm, said two support beams being subsequently capable of being structurally re-attached to enable a reversible transformation of said second configuration into said first configuration.
