  • Patent number: 11266400
    Abstract: A knotless self-cinching suture construct device includes a shuttling suture, a continuous loop and a self-cinching suture member. The shuttling suture is configured for insertion into a passage hole in injured soft tissue, such as a torn or damaged meniscus in the knee. The shuttling suture and continuous loop are passed entirely through the passage hole in the tissue, and the self-cinching suture member is inserted through the continuous loop to form a hitch using the continuous loop around the tissue. The self-cinching suture member is then pulled tight, allowing a first strand to slide through both the hitched continuous loop and a self-cinching sleeve on the suture member. When tension is applied, the sleeve tightens around the strand much like a finger trap, preventing inadvertent release of the applied suture tension. The suture construct is configured for use through a transosseous tunnel with a suture button in some embodiments.

  • Patent number: 11039821
    Abstract: A drug supply device for supplying drug to a living body surface that includes a shaft and a drug holding sheet attached to the distal end of the shaft. The drug holding sheet has a first face that faces distally and a second face opposite the first face that faces proximally when the drug holding sheet is expanded. The drug holding sheet includes folded portions that fold such that the first face is positioned to face radially inward while exposing the second face to an outside environment when the drug holding sheet is in a folded state. A drug is applied on the first face of the drug holding sheet. The drug supply device includes an expandable member on the second face of the drug holding sheet. The expandable member is expandable to cause the drug holding sheet to expand from the folded state into the expanded state.

    Abstract: A left atrial appendage (LAA) occluder is provided. The LAA occluder includes a sealing disc and an anchoring device, both of which are mutually connected; a part where an LAA cooperates with the anchoring device is an anchoring net, and the anchoring net is of a backboneless structure. The whole anchoring device is of the backboneless structure. The anchoring device is formed by weaving super elastic metal wires or shape memory alloy wires, a distal end of the anchoring device is opened, and a proximal end of the anchoring device is constricted and is connected with the sealing disc to form a conical net. The distal end of the anchoring device is opened and is rolled towards the proximal end to form the anchoring net, and the anchoring net surrounds the conical net. The anchoring net is connected with the conical net through an arc transition area.

  • Patent number: 11006938
    Abstract: The present disclosure provides collapsible medical devices that may be introduced via a delivery device into a pre-existing patent foramen ovale or trans-septal puncture hole and left in place to provide both a sealing function on the atrial wall and a septal-access function for additional procedures. The disclosed medical devices include a penetrable and re-sealable gasket material disposed in an open lumen in the medical device. This penetrable and re-sealable material allows catheters or other medical devices to pass therethough for providing additional therapy to an individual. By allowing the access point or portal to be opened by a guidewire or another medical tool, the medical devices as disclosed herein may be particularly suitable for a variety of cardiac procedures including, for example, atrial fibrillation, mitral valve replacement or repair, left atrial appendage closures, and the like.

  • Patent number: 10959832
    Abstract: A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of hone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression.

  • Patent number: 10932786
    Abstract: The present teachings provide a device to close a ductus arteriosus percutaneously. One aspect of the present teachings provides a device comprising at least one flange portion configured to be positioned against a vascular wall outside one end of a ductus arteriosus, and a body portion configured to be positioned inside the ductus arteriosus. The body portion of the device has a length adjustable in order for the device to fit inside patients with various ductus arteriosus lengths. The at least one flange portion of the device has pivotability in order for at least one flange to deflect from the longitudinal axis of the body portion so that the deployed device can be positioned at a treatment site allowing the discs to sit flat against the vascular tissue to promote closure while avoiding disruption of flow within the pulmonary artery and aorta or applying excess pressure to the surrounding vascular tissue.
