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;
the plurality of actuation elements comprises a first plurality of actuation elements reversibly coupled to a proximal end of the replacement heart valve, wherein the first plurality of actuation elements are adapted to apply a distally directed force on the replacement heart valve after the anchor is outside of the delivery sheath.
