MEDICAL DEVICE WITH TENSIONABLY ATTACHED REMODELABLE MATERIAL
First Claim
1. 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.

Abstract
Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device includes a support frame having struts and a weakened frame portion, and a remodelable material tensionably attached to the support frame. The weakened frame portion has 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. The remodellable material restricts expansion of the frame from a radially compressed configuration to a radially expanded configuration when the weakened frame portion is in the first configuration. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein.

19. 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, third and fourth struts positioned along the perimeter, a first weakened frame portion positioned on the perimeter and joining the first and second struts, and a second weakened frame portion positioned on the perimeter and joining the third and fourth struts, the first weakened frame portion positioned opposite the second weakened frame portion with respect to the lumen; 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 extending along the third strut to the second weakened frame portion, 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 first and second weakened frame portions each have 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 wherein the remodelable material is tensionably attached to the first and third struts such that the remodelable 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.

20. 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, third and fourth struts positioned along the perimeter, a first weakened frame portion positioned on the perimeter and joining the first and second struts, and a second weakened frame portion positioned on the perimeter and joining the third and fourth struts, the first weakened frame portion positioned opposite the second weakened frame portion with respect to the lumen; 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 extending along the third strut to the second weakened frame portion, 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 first and second weakened frame portions each have 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; wherein the first weakened frame portion comprises a first curved frame segment attached to the first strut at a first dislocating joint and attached to the second strut at a second dislocating joint and the second weakened frame portion comprises a second curved frame segment attached to the third strut at a third dislocating joint and attached to the fourth strut at a fourth dislocating joint; and wherein the remodelable material is tensionably attached to the first and third struts such that the remodelable 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.
