Patent ID: 8876876

Claim:
A prosthesis delivery system comprising: a prosthesis having a longitudinal body generally disposed about an axis, the longitudinal body having proximal and distal ends, the proximal end of the prosthesis having a proximal locking device comprising a first proximal extension extending proximally from the proximal end of the longitudinal body, the first proximal extension having located thereon first and second radially extending and spaced-apart locking members, the first locking member having a first proximal facing surface and the second locking member having a first distal facing surface, the first proximal facing surface and the first distal facing surface opposing one another, the first proximal facing surface and the first distal facing surface being spaced-apart by the first distance; an elongate flexible guide having a proximal section and a distal section, the distal section configured for mounting the prosthesis and having a first radially extending member positioned proximal to a distal end of the elongate guide and having a width approximately equal to the first distance, the first radially extending member having a second proximal facing surface and a second distal facing surface, the prosthesis being mounted on the distal section of the elongate guide, the first proximal facing surface positioned to abut or nearly abut the second distal facing surface and the first distal facing surface positioned to abut or nearly abut the second proximal facing surface, wherein the first radially extending member comprises a cylindrical member that is sandwiched between the first and second locking members, the cylindrical member comprising a coil; and a sheath disposed over at least a portion of the elongate guide to constrain the prosthesis on the elongate guide.
