The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

Stent Graft

A stent graft includes a tubular member and a plurality of stent rings. The plurality of stent rings are alternately bent toward a central end side and toward a peripheral end side. The plurality of stent rings include a plurality of fluctuating rings and a small fixed ring. The plurality of fluctuating rings are arranged in order of a first fluctuating ring, a second fluctuating ring . . . , from the proximal end side toward the distal end side. A first distance that is a maximum value of a distance between a center position of the first fluctuating ring and a center position of the second fluctuating ring is greater than any nth distance that is a maximum value of a distance between a center position of an nth fluctuating ring and a center position of an n+1th fluctuating ring.

20230144045 · 2023-05-11 ·

A prosthetic valve including a leaflet frame configured to be transitioned from a collapsed state having a first diameter to an expanded state having a second diameter that is larger than the first diameter. The leaflet frame has an inlet and outlet end and defining a longitudinal axis. The leaflet frame includes a plurality of frame members that form a framework defining plurality of cells each having an interior cell space, the plurality of cells including an attachment cell. The plurality of frame members includes a plurality of sub-cell attachment members extending into the interior cell space of the attachment cell, the sub-cell attachment members each being configured to define a plurality of attachment locations along a sub-cell attachment line defined within a plane that intersects with the longitudinal axis such that the sub-cell attachment line extends through the interior cell space of the at least one attachment cell.

A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body and an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body, wherein the at least one collagen receiving structure is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair.

DEVICE AND METHOD WITH REDUCED PACEMAKER RATE IN HEART VALVE REPLACEMENT

The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve.

System To Assist In The Release Of A Collapsible Stent From a Delivery Device

A delivery device for an implantable medical device having a retention member at an end thereof may include a shaft extending in a longitudinal direction and defining a longitudinal axis, an elongated sheath surrounding a longitudinal portion of the shaft, a compartment defined inside the sheath and adapted to receive the medical device in an assembled condition, a retainer positioned at one end of the compartment, and an energy storage element positioned on the longitudinal portion of the shaft and configured to be radially compressed by the medical device when the elongated sheath covers the compartment containing the medical device. The sheath may be slidable relative to the shaft in the longitudinal direction. The retainer may include a recess adapted to receive the retention member of the medical device in the assembled condition.

20230201013 · 2023-06-29 ·

A self-sealing tubular graft is provided for implantation within a patient's body that includes an elongate tubular body including first and second self-sealing cannulation regions and a loop region extending between the first and second cannulation regions. The loop region includes one or more reinforcement members attached to a first length of the loop region and extending at least partially around a circumference of the tubular body. For example, the reinforcement members may include one or more sinusoidal or zigzag members extending along the first length with alternating peaks and valleys extending at least partially around a circumference of the tubular body. Self-sealing patches are also provided that include one or more reinforcement members embedded within base material.

SOFT TISSUE GRAFTS, AND METHODS OF MAKING AND USING SAME

Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.

20230190498 · 2023-06-22 · ·

Stents generally can include a tubular structure having circumferentially positioned undulating wires that extend over a majority of a length of the stent such that the undulations oscillate circumferentially to define a circumference of the stent. The undulations can wrap over and under adjacent undulations to form an interwoven structure. Additionally, or alternatively, adjacent wires can be joined. Wires forming the stent can be cut from elastic tubing such that each wire has a three-dimensional shape.
