Abstract
A method for endovascularly replacing a patient's heart valve including the following steps: endovascularly delivering an anchor and a replacement valve supported within the anchor to a vicinity of the heart valve in a collapsed delivery configuration, the anchor having grasping elements adapted to grasp tissue in a vicinity of the heart valve; expanding the anchor, thereby rotating the grasping elements; and grasping the tissue with the rotating grasping elements.

(canceled)
A replacement heart valve implant, comprising:
- an expandable tubular anchor member having a delivery configuration and a deployed configuration, the expandable tubular anchor member defining a lumen extending axially therethrough along a central longitudinal axis from an inflow end of the expandable tubular anchor member to an outflow end of expandable tubular anchor member;
- a plurality of valve leaflets disposed within the lumen of the expandable tubular anchor member;
- a first circumferential set of grasping elements extending radially outward from the expandable tubular anchor member proximate the inflow end of the expandable tubular anchor member;
- and
- a second circumferential set of grasping elements extending radially outward from the expandable tubular anchor member, the second circumferential set of grasping elements being spaced apart axially from the first circumferential set of grasping elements toward the outflow end of the expandable tubular anchor member.

A replacement heart valve implant, comprising:
- an expandable tubular anchor member having a delivery configuration and a deployed configuration, the expandable tubular anchor member having a body defining a lumen extending axially therethrough along a central longitudinal axis from an inflow end of the expandable tubular anchor member to an outflow end of expandable tubular anchor member;
- a plurality of valve leaflets disposed within the lumen of the body of the expandable tubular anchor member;
- a first circumferential set of grasping elements extending radially outward from the body of the expandable tubular anchor member proximate the inflow end of the expandable tubular anchor member, the first circumferential set of grasping elements being configured to resist downstream migration of the expandable tubular anchor member through a native heart valve;
- a second circumferential set of grasping elements extending radially outward from the body of the expandable tubular anchor member, the second circumferential set of grasping elements being spaced apart axially from the first circumferential set of grasping elements toward the outflow end of the expandable tubular anchor member;
- and
- a tubular seal member disposed exterior to the body of the expandable tubular anchor member, the tubular seal member being configured to prevent blood flow around the expandable tubular anchor member in the deployed configuration.
