Belt for prosthetic heart valve

An assembly, comprising:

• an implantable prosthetic device comprising a frame movable between a radially compressed configuration and a radially expanded configuration;
• and
• a belt extending circumferentially around the frame, the belt comprising an annular body including a plurality of alternating peaks and valleys and a plurality of discrete circumferentially extending frangible members extending between at least one of adjacent peaks and adjacent valleys;
• wherein the annular body is movable between a radially compressed state and a radially expanded state;
• and
• wherein the belt is configured to radially expand to a first diameter when a first force below a predetermined threshold of force is applied and expand to a second diameter when a second force greater than the predetermined threshold of force is applied.

• the belt further comprising an annular body including a plurality of alternating peaks and valleys, the annular body being movable between a radially compressed state and a radially expanded state;
• wherein the belt comprises a plurality of frangible members, and wherein a first frangible member of the plurality of frangible members is configured to break when the second force applied to the belt, allowing the belt to radially expand to the second diameter;
• and
• wherein the distance between adjacent peaks of the plurality of alternating peaks and valleys is a first length when the annular body is in the radially compressed state, wherein the distance between adjacent peaks of the plurality of alternating peaks and valleys is a second length when the annular body is in the radially expanded state, and wherein the second length is greater than the first length.
