Abstract:
A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.

Claim (Index 1):
A kit for implanting a heart valve, the kit comprising:\n a heart valve and an expandable sheath, the expandable sheath comprising:\n an expandable outer member including a lumen extending therethrough; \n an inner member extending longitudinally within the lumen of the outer member, the inner member defining a central lumen of the sheath and including a folded portion; \n at least two reinforcing members extending longitudinally along a length of the sheath, \n wherein the inner and outer member are configured to expand to allow passage of an implant through the central lumen of the inner member, \n wherein expansion of the sheath causes a circumferential distance between the at least two reinforcing members to increase from a first circumferential distance to a second circumferential distance.
