1. A prosthetic valve for implantation in a body vessel having an expanded configuration and a compressed configuration, the prosthetic valve comprising:
- a flexible covering having a proximal covering end, a distal covering end, a luminal surface, an abluminal surface, and an axial length extending between the proximal covering end and distal covering end, the flexible covering defining an interior lumen, the flexible covering having a longitudinal axis extending between the proximal covering end and the distal covering end and a circumference extending around the abluminal surface;
a plurality of discrete shaping members attached only to the flexible covering, each of the discrete shaping members comprising a discontinuous Z-stent segment having a V-shape with a first free end, a second free end, and an apex, each of the Z-stent segments extending only partially around the circumference of the flexible covering; and
at least one valve member operatively connected to the luminal surface, the at least one valve member adapted to modify fluid flow through the interior lumen;
wherein each of the first free end, second free end, and apex of each Z-stent segment is disposed on the flexible covering between the proximal covering end and the distal covering end.

Abstract
The invention relates to a prosthetic valve for regulating flow through a body lumen. The medical device comprises discrete shaping members, a flexible covering, and a valve member. The discrete shaping members are operatively attached to the flexible covering, such that the medical device may exhibit low radial force and dynamic movement.

16. A prosthetic valve for implantation in a body vessel having an expanded configuration and a compressed configuration, the prosthetic valve comprising:
-
a flexible covering defining a body region surrounding an interior lumen extending between a proximal covering end and a distal covering end, the flexible covering having an axial length extending between the proximal covering end and the distal covering end, a luminal surface defining the interior lumen, an abluminal surface, a longitudinal axis extending between the proximal covering end and the distal covering end, and a circumference extending around the abluminal surface; a plurality of discrete shaping members individually attached to only the flexible covering, each of the discrete shaping members comprising a discontinuous Z-stent segment having a V-shape with a first free end, a second free end, and an apex, each of the Z-stent segments extending only partially around the circumference of the flexible covering, the plurality of discrete shaping members being adapted to move circumferentially relative to one another along the abluminal surface of the flexible covering when the prosthetic valve is moved between the compressed configuration and the expanded configuration; and at least one valve member operatively connected to the luminal surface, the at least one valve member adapted to modify fluid flow through the interior lumen; where the interior lumen has a larger cross-sectional area in at least a portion surrounding the at least one valve member than at the proximal covering end and the distal covering end to create an artificial sinus; and where each of the first free end, second free end, and apex of each Z-stent segment is disposed on the flexible covering between the proximal covering end and the distal covering end. - View Dependent Claims (17, 18, 19, 20, 21)
