  • Patent number: 8444672
    Abstract: A device for attaching connective tissue to bone has a longitudinal axis and comprises an annular toggle member and a body member disposed distally of the toggle member, such that there is an axial space between the toggle member and the body member. The toggle member is movable between an undeployed position wherein the toggle member has a smaller profile in a direction transverse to the axis and a deployed position wherein the toggle member has a larger profile in the direction transverse to the axis. When installed in a desired procedural site, in suitable bone, suturing material extends axially through a center aperture in the annular toggle member, without being secured to or contacting the toggle member. This approach permits a suture attachment which lies entirely beneath the cortical bone surface, and which further permit the attachment of suture to the bone anchor without the necessity for tying knots, which is particularly arduous and technically demanding in the case of arthroscopic procedures.

  • Patent number: 8414599
    Abstract: A surgical tensioning device for dynamically holding two tissue portions in contact with one another comprises a resilient member having a plurality of extending portions which are spaced from one another and are capable of resiliently moving toward and away from one another. A plurality of attachment points are provided on the resilient member, for attaching a securing member, such as suture or a surgical screw, thereto. A spacer member is placeable between the plurality of extending portions to retain the extending portions at a fixed distance from one another, and is removable from between the plurality of extending portions after the securing members are in place so that said tension is transferred from the spring to the suture or other securing members. The result is an ability to hold two tissues in a state of compression beyond that which is commonly and consistently achieved with the hand tying of sutures.

  • Patent number: 8303591
    Abstract: A surgical tensioning device for dynamically holding two tissue portions in contact with one another comprises a resilient body having a plurality of spring elements, and a plurality of stop members for limiting travel of the spring elements in order to control energy stored or delivered by the spring elements. A length of suture is also provided, wherein a first end of the suture is connected to the resilient body at a first attachment point and a second end of the suture is connected to the resilient body at a second attachment point. In one embodiment, the stop members contact one another to limit compression of the spring elements. When the suture is placed in tension, the spring elements move to an extended configuration and the stop members move apart, creating gaps between ends of each of the stop members.

  • Patent number: 8109966
    Abstract: An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.

  • Patent number: 7674274
    Abstract: A bone anchor device for attaching connective tissue to bone comprises a disk adapted for insertion into a portion of bone to which the connective tissue is to be attached. The disk is movable between a bent orientation for presenting a smaller cross-section and an expanded orientation for presenting a larger cross-section. The bent orientation is utilized for inserting the disk through a small hole into a region of cancellous bone beneath the cortical bone layer, after which the disk is actuated to its expanded orientation so that it will be permanently anchored in the cancellous bone, as it will be too large to return proximally through the hole in the cortical bone layer. Two embodiments are disclosed. In a first embodiment, the disk is initially formed in the expanded orientation, of spring steel. In a second embodiment, the disk is initially formed in the bent orientation, and spring steel is not required.
