Patent ID: 8128682

Claim:
An implantable medical device, comprising: a self-expandable support frame having radially compressed and radially expanded configurations, the support frame having a perimeter that defines a lumen and comprising first, second, and third struts positioned along the perimeter, and a weakened frame portion joining the first and second struts and having a first configuration in which the support frame has a first outward radial force and a second configuration in which the support frame has a second, lesser outward radial force; and a remodelable material having first, second and third edges, the first edge attached to the first strut and extending along the first strut to the weakened frame portion, the second edge attached to the third strut, and the third edge extending between the first and second edges and across the lumen and comprising a free edge not attached to the support frame; wherein the remodelable material is tensionably attached to the first and third struts such that the remodlable material restricts expansion of the support frame from the radially compressed configuration to the radially expanded configuration when the weakened frame portion is in the first configuration.
