Bowed runners and corresponding valve assemblies for paravalvular leak protection
First Claim
1. A prosthetic heart valve for replacing a native valve, comprising:
- a stent extending between a proximal end and a distal end and including a plurality of struts forming cells, the stent having a collapsed condition and an expanded condition;
at least one runner coupled to a cell, the at least one runner being configured to transition from a first configuration to a second configuration when the stent moves from the collapsed condition to the expanded condition, the at least one runner projecting radially outwardly from the cell in the second configuration; and
a valve assembly disposed within the stent, the valve assembly including a covering material disposed on an abluminal surface of the stent,wherein the covering material includes a plurality of individual panels, each of the plurality of individual panels configured to cover only one cell and the at least one runner.

Abstract
A prosthetic heart valve for replacing a native valve includes a stent extending between a proximal end and a distal end and including a plurality of struts forming cells, the stent having a collapsed condition and an expanded condition. At least one runner is coupled a cell, the at least one runner being configured to transition from a first configuration to a second configuration when the stent moves from the collapsed condition to the expanded condition, the at least one runner projecting radially outwardly from the cell in the second configuration. A valve assembly is disposed within the stent, the valve assembly including a plurality of leaflets, a cuff at least partially disposed on a luminal surface of the stent, and a covering material disposed on an abluminal surface of the stent and covering the at least one runner in the second configuration.

11. A prosthetic heart valve for replacing a native valve, comprising:
-
a stent extending between a proximal end and a distal end and including a plurality of struts forming cells and a plurality of runners, the stent having a collapsed condition and an expanded condition, the struts defining a first diameter in the expanded condition and the runners defining a second diameter in the expanded condition, the second diameter being greater than the first diameter; and a valve assembly disposed within the stent, the valve assembly including a covering material disposed on an abluminal surface of the stent, wherein the covering material includes a plurality of individual panels, each of the plurality of individual panels configured to cover only one of the cells and one of the plurality of runners. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
