Low profile heart valve and delivery system
First Claim
1. A delivery system for endovascularly replacing a heart valve of a patient, comprising:
- a replacement heart valve and an expandable anchor are adapted to be delivered within a delivery sheath to a vicinity of the heart valve;
a delivery tool comprising a plurality of actuation elements, wherein the plurality of actuation elements are reversibly coupled to the replacement heart valve, andwherein the plurality of actuation elements are adapted to apply an axially directed force on the replacement heart valve to deploy the anchor after the anchor is outside of the delivery sheath, and the anchor is adapted to be foreshortened and to self-expand to a partially expanded configuration outside of the delivery sheath.
