Abstract:
1. A catheter comprising: a) an elongate body having a proximal end and a distal end; b) a retractable sheath mounted on the elongate body proximate the distal end, the sheath and elongate body cooperating to define a first compartment therebetween for receiving a valve prosthesis; c) a first elongate generally rigid linkage extending from a proximal region of the compartment toward the proximal end of the catheter; d) a second elongate, generally rigid linkage extending from a distal region of the compartment toward the proximal end of the catheter; and e) a valve prosthesis for replacing a portion of a lumenal valve, the valve prosthesis including a leaflet attached to a deformable structural circumferential portion mounted in the compartment, the deformable structural circumferential portion of the valve prosthesis having a curved shape when fully deployed and having a first circumferential end and a second circumferential end separated by a gap that is spanned at least in part by the leaflet, the deformable structural circumferential portion having a proximal portion near the first circumferential end attached to the first linkage and a distal portion near the second circumferential end attached to the second linkage, wherein:
