  • Patent number: 11272915
    Abstract: Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical soft tissue repair device includes a snare assembly coupled to a soft anchor in which the soft anchor has a first, unstressed configuration that can be used to insert the anchor into bone and a second, anchoring configuration that can be used to fixate the anchor in the bone. The snare assembly can be configured to actuate the anchor from the first configuration to the second configuration, and it can also be used to engage and approximate tissue by drawing the tissue closer to the anchor fixated in the bone. The snare assembly can be used in conjunction with a number of different anchor configurations, and other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

  • Patent number: 11266426
    Abstract: A single integrated intravascular device including a stentriever and semi-compliant balloon housed therein. After traversing a clot, the device is deployed to a self-expanded state engaging the clot therein, whereupon the device along with the embedded clot is removed. Detecting through imaging a stenosis at an original position of the captured clot, the device is reintroduced to that location and the stentriever is deployed to a self-expanded state. Inflating the semi-compliant balloon enlarges the stentriever to a hyper-expanded state greater than the self-expanded state thereby dilating the vessel while simultaneously completely detaching/releasing the stentriever from a remaining portion of the device. Then the semi-compliant balloon is collapsed and withdrawn along with the remaining portion of the device, while the detachable/releasable portion of the stentriever in the self-expanded state remains in the vessel.

  • Patent number: 11219444
    Abstract: A surgical device includes a first fastener having a planar profile, a second fastener having a concave surface, and a suture that can be manipulated to change a distance between the first and second fasteners. The second fastener has a curvature that substantially matches the curvature of a top surface of a clavicle bone in a direction perpendicular to a long axis of the clavicle bone. A method of treating an acromioclavicular joint injury includes forming axially aligned passages through a patient's clavicle and coracoid process, passing a fastener having a concave surface through the passages, positioning the concave surface of the fastener against a top surface of the patient's clavicle with a long axis of the fastener extending perpendicular to a long axis of the clavicle, positioning a fastener having a planar profile below the patient's coracoid process, and adjusting a suture that couples the fasteners.
