Abstract: A replacement heart valve locking mechanism may include a buckle member fixedly attached to a tubular anchor member defining a central longitudinal axis, a post member axially translatable relative to the buckle member, and an actuator member releasably connected to the post member at an attachment point. The post member may include a latch portion configured to engage a catch formed in the buckle member such that movement of the post member distally relative to the buckle member is prevented. The attachment point may be disposed proximal of the latch portion. Circumferential translation of the latch portion about the central longitudinal axis may disengage the latch portion from the catch.

Abstract: A replacement heart valve implant may include a braided anchor member configured to actuate between a delivery configuration and a deployed configuration formed from a plurality of filaments, a circumferential seal member disposed about a distal portion of the anchor member and including a reinforcing band disposed at a distal end thereof, and a plurality of valve leaflets connected to the anchor member. The reinforcing band is secured to the anchor member adjacent a distal end of the anchor member by a plurality of lashings each attached to two individual filaments. The plurality of filaments defines a body section, a proximal crown section, and a distal crown section, wherein the proximal crown section includes a first plurality of end loops and a second plurality of end loops, wherein a proximalmost extent of the first plurality of end loops and the second plurality of end loops varies.

Abstract: A replacement heart valve implant may include a tubular anchor member actuatable between a delivery and a deployed configuration, the tubular anchor member including an inflow end, an outflow end, and a plurality of anchor member intersection points, and defining a longitudinal axis extending from the inflow end to the outflow end, a plurality of valve leaflets, and a seal member secured to the tubular anchor member at the inflow end. An end surface of each of the plurality of valve leaflets may abut an inner-facing surface of the seal member. The plurality of valve leaflets each define a secured end and a free end. The secured end may be attached to the seal member adjacent the inflow end. The secured end may define the end surface, and the end surface may face toward the outflow end when the plurality of valve leaflets is in an everted position.
