Abstract: A tissue modification apparatus includes a first and a second guide, a first and a second set of mounts, and a first and a second actuator. The first guide defines a first axis, and the second guide defines a second axis intersecting the first axis. The mounts of the first set of mounts are movable relative to one another along the first axis, and the mounts of the second set of mounts are movable relative to one another along the second axis. The first actuator and the second actuator are each settable to a stress load, with the first actuator and the second actuator movable, respectively, along the first axis and the second axis to transmit each respective stress load to a piece of tissue mechanically coupled to the first and second set of mounts.

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.
