Abstract:

Techniques are described for delivering a replacement valve to a target location in a patient. In one example, a medical device system includes an implantable medical device comprising an expandable anchor, a locking member engaged to a first end of the anchor, two posts configured to engage the locking member, each of the posts being engaged to a portion of the anchor, each post defining a hole at a distal end of the post, and a fastening element extending through each hole of a respective post and being engaged to a second end of the anchor, where, in a locked configuration, the posts are secured to the locking member.

International Classification:

A61F 2/24

US Classification:

623 214, 623 218

Abstract:

A prosthetic heart valve includes a radially expandable stent and a plurality of leaflets. Each leaflet includes a coaptation portion, an arcuate edge, and a belly. The coaptation portion is movable relative to respective coaptation portions of the other leaflets. The acuate edge has a first end and a second end and is coupled to the stent. The belly extends from the arcuate edge to an axis defined by the first and second ends of the arcuate edge, wherein the ratio of the surface area of the belly to the outer cross-sectional area of the expanded stent is about 0.09 to about 0.16.

B23P 11/00

US Classification:

623 219, 29428

Abstract:

A prosthetic heart valve includes an expandable stent and a leaflet assembly coupled to the expandable stent. The expandable stent is radially expandable from a first size for intraluminal delivery through a body passageway to a second size for implantation of the prosthetic heart valve in the body passageway. The leaflet assembly includes leaflets movable between an open position permitting flow past the expanded stent and a closed position substantially restricting flow past the expanded stent. Each of the leaflets is coaptable with each of the other leaflets in the closed position to define a coaptation region of about 15 percent to about 35 percent of the overall height of each of the plurality of leaflets.

International Classification:

A61F 2/02

US Classification:

623 2372

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.

International Classification:

A61F 2/24

US Classification:

623 218

Abstract:

An apparatus for endovascularly replacing a patient's heart valve comprises an anchor having an outer surface and an inner surface. The anchor is expandable from a collapsed delivery configuration to a fully deployed configuration. A first locking element and a second locking element are attached to the inner surface of the anchor. The first locking element is engageable with the second locking element. At least one of the first locking element and the second locking element has a curved outer surface. Methods for attaching the second locking element to the anchor are also provided.

International Classification:

A61F 2/24

Abstract:

A replacement heart valve comprises a unibody, folded, double-wall stent, with a stent cover and a leaflet valve attached to the inner lumen of the stent. The heart valve is delivered using a multi-pulley, suture-based stent restraint assembly provided by fixed guide openings or structures along the distal end of the delivery system that independently permits expansion of the distal and proximal ends of the outer wall of the stent, and control of the inner wall expansion simultaneously with or separately from the expansion of the outer wall.

A61M 25/01
A61M 25/09
A61F 2/24

Abstract:

Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.
