Patents by Inventor Michael Hendricksen

Michael Hendricksen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220323054
    Abstract: A method of treating a patient's joint having opposing joint surfaces includes providing an elongate member having a proximal end, a distal end and an expandable member near the distal end. The expandable member is positioned in the joint between the joint surfaces and expanded so as to separate the joint surfaces away from one another into a distracted position. The joint is manipulated while in the distracted position so that the joint is distracted and in flexion. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.

  • Patent number: 11000267
    Abstract: Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures.

  • Patent number: 10588614
    Abstract: A knotless suture anchoring system includes an outer anchor having a central channel and a distal tip adapted to penetrate tissue. An inner anchor is positionable in the central channel of the outer anchor and a locking feature on one or both of the inner and outer anchors retains the inner anchor within the central channel. A continuous length of suture is coupled with the inner and outer suture anchors and has a free end. At least one of the inner and the outer anchors also has a cinching mechanism that allows the suture to be tensioned by passage of the suture through the cinching mechanism in a first direction while movement of the suture through the cinching mechanism in a second direction opposite the first direction is constrained.

  • Patent number: 10582919
    Abstract: Various devices, systems and methods for knotless anchoring of sutures to repair bodily tissue are disclosed. These devices allow sutures to be anchored to bone or other tissues, and more specifically provide a suture anchor which eliminates the need for the operator to knot the suture to secure the suture under tension. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts and find particular utility in hip and shoulder arthroscopy, e.g. labral reattachment, rotator cuff repair, and similar procedures.

  • Publication number: 20170265984
    Abstract: Devices and methods are disclosed for providing access to a central compartment of a hip joint. The devices can access the central compartment by distracting all or a portion of the labrum. The labrum can be distracted by advancing a device underneath the bottom edge of the labrum, and using the device to further distract the labrum. Some devices can move underneath the labrum to provide a gap for other devices to access the central compartment.
