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 and extending within 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 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, the covering material including at least one individual panel configured to cover one cell of the stent, each of the at least one individual panel being disposed over only one of 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.

10. 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, at least one of the plurality of runners extending within one of the cells, the stent having a collapsed condition and an expanded condition, the struts, in the expanded condition of the stent, defining a first diameter and the runners, in the expanded condition of the stent, defining a second diameter, the second diameter being greater than the first diameter; and
a valve assembly 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 configured to cover at least one of the cell and at least one of the plurality of runners.
- a stent extending between a proximal end and a distal end and including a plurality of struts forming cells and a plurality of runners, at least one of the plurality of runners extending within one of the cells, the stent having a collapsed condition and an expanded condition, the struts, in the expanded condition of the stent, defining a first diameter and the runners, in the expanded condition of the stent, defining a second diameter, the second diameter being greater than the first diameter; and
