  • Patent number: 11872622
    Abstract: Proposed is a nitinol nanofiber with an average surface roughness that is enhanced through mechanical and chemical treatments. The enhanced surface roughness improves biocompatibility and promotes tissue growing, thereby improving the bioavailability of the nitinol nanofiber. The nitinol nanofiber undergoes infrared irradiation whereby the nitinol fiber exhibits improved tensile strength, elastic modulus, and maximum restorative stress. Therefore, fatigue fraction does not easily occur in the nitinol fiber even when the nitinol nanofiber has a constant roughness. The present invention provides bio-use or medical nitinol nanofibers that are highly biocompatible.

  • Patent number: 10111764
    Abstract: A prosthesis may include a tubular frame comprising rings which are concentric along an axis of the tubular frame. The rings may have a serpentine shape with apexes in a longitudinal direction such that the rings are configured to move between a compressed configuration and an expanded configuration. A first ring of the rings can include a first apex that includes a first anchoring member extending radially outward and a first crossbar extending radially inward. The first ring can further include a second apex that neighbors the first apex. The first crossbar can extend toward the second apex and extend radially inward further than the second apex. When in the compressed configuration, the first crossbar can engage the second apex such that the first anchoring member is moved radially inward.

  • Patent number: 9788948
    Abstract: A tissue anchor is provided that includes a proximal head at a proximal end of the tissue anchor, and a helical tissue-coupling element disposed about a longitudinal axis thereof, extending to the proximal head, and having a distal tissue-penetrating tip. The helical tissue-coupling element includes a first helical portion and a second helical portion more distal than the first axial portion. The first and the second helical portions of the helical tissue-coupling element have a first axial stiffness and a second axial stiffness, respectively. The second axial stiffness is greater than the first axial stiffness, such that if excessive tension is applied to the helical tissue-coupling element, the helical tissue-coupling element generally elongates along the first helical portion before along the second helical portion, such that the first helical portion serves as a mechanical fuse that reduces force applied to the second helical portion.

  • Patent number: 9642734
    Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion coupled to the anchor. The protrusion, in a constrained state, extends a distance from an exterior surface of the anchor and, in an unconstrained state, extends further from the exterior surface of the anchor. Also included is a biodegradable constraint, such as a biodegradable tube or suture, configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints, each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.

  • Patent number: 9597180
    Abstract: A stent for use in a prosthetic heart valve has a plurality of expandable and collapsible closed cells, a portion of which form an annulus section adapted for placement within the annulus of the native heart valve. Anchor features of the stent residing within at least some closed cells are adapted to engage tissue of the heart, including native valve leaflets, the sinotubular junction, or another implanted device when the prosthetic valve is implanted in the heart. The anchor features may help to retain the prosthetic valve in position, without interfering with the opening and closing of the valve leaflets. Furthermore, the anchor features may be configured to allow the stent to be resheathed into a delivery device after the portion of the stent with the anchor feature has expanded out of the delivery device.
