MECHANICALLY EXPANDING HEART VALVE AND DELIVERY APPARATUS THEREFOR
First Claim
1. A prosthetic valve comprising:
- a radially expandable and compressible frame comprising a plurality of interconnected struts, each strut having a first end, a second end, and a length extending from the first end to the second end, each strut comprising a plurality of linear segments that are laterally offset from each other in a direction perpendicular to the lengths of the struts; and
a valvular structure mounted to the frame and configured to regulate the flow of blood through the prosthetic valve.

Abstract
An assembly can comprise a radially expandable and compressible annular frame, at least one linear actuator assembly coupled to the frame and at least one locking mechanism coupled to the frame. The linear actuator can be configured to apply a distally directed force and/or a proximally directed force to the frame to radially expand or compress the frame. The locking mechanism can comprise a first sleeve member connected to the frame at a first location, a second sleeve member having internal threads and being connected to the frame at a second location, and a first screw configured to engage the internal threads of the second sleeve member to retain the frame in a radially expanded state.
