TRANSCATHETER MITRAL VALVE AND DELIVERY SYSTEM
First Claim
1. A prosthetic heart valve having an inflow end and an outflow end, comprising:
- a stent having a collapsed condition and an expanded condition;
a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets; and
a body coupled to the stent and formed of braided wire, the body being transitionable between an unfurled condition and a furled condition, the furled condition forming a flange capable of at least partially anchoring the prosthetic heart valve within a native valve annulus.

Abstract
A prosthetic heart valve includes a collapsible and expandable stent, a collapsible and expandable valve assembly disposed within the stent, and one or more features coupled to the stent for at least partially anchoring the prosthetic heart valve within a native valve annulus of a patient. The anchoring features may include a body transitionable from an unfurled condition to a furled condition, the furled condition forming a flange for at least partially anchoring the heart valve, and/or a plurality of hooks transitionable from a deformed condition to a relaxed condition for at least partially anchoring the heart valve. A delivery device for the prosthetic heart valve may include a handle and a catheter member extending from the handle and having a first portion, a second portion, and a compartment for receiving the valve. The delivery device may provide for staged deployment of the valve.

11. A prosthetic heart valve having an inflow end and an outflow end, comprising:
-
a stent having a collapsed condition and an expanded condition; a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets; and a plurality of hooks coupled to the stent and transitionable between a deformed condition and a relaxed condition, the plurality of hooks extending toward the inflow end in the relaxed condition to at least partially anchor the prosthetic heart valve within a native valve annulus. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method of deploying a prosthetic heart valve from a delivery device at a target site in a patient, the heart valve including a stent having a collapsed condition and an expanded condition, a collapsible and expandable valve assembly disposed within the stent, a body assembled to the stent and being transitionable between an unfurled condition and a furled condition, and a plurality of hooks coupled to the stent and being transitionable between a deformed condition and a relaxed condition, the method comprising:
-
introducing the prosthetic heart valve to the target site in a collapsed configuration; deploying the plurality of hooks to transition the plurality of hooks from the deformed condition to the relaxed condition; deploying the body to transition the body from the unfurled condition to the furled condition; and decoupling the prosthetic heart valve from the delivery device after the plurality of hooks are in the relaxed condition and the body is in the furled condition, whereby the plurality of hooks and the body cooperate to anchor the prosthetic heart valve at the target site. - View Dependent Claims (20)
