  • Patent number: 7588586
    Abstract: A tissue fixation device is provided that is preferably used to secure a ligament or graft within a prepared bone tunnel, for example in ACL replacement. The tissue fixation device generally includes an elongate member having a shaft portion that is adapted to be at least partially disposed within a bone tunnel, and a guide member that forms a portion of the proximal end of the elongate member. The guide member has a graft-seating surface that is effective to seat a graft and to position the graft toward one side of a bone tunnel when the device is disposed within the bone tunnel. The device also includes a graft-retaining member formed on at least a portion of the graft-seating surface.

  • Publication number: 20090204081
    Abstract: Various methods and devices are provided for accessing an interior surgical site using an access portal which can be inserted and removed with minimal tissue damage and which can form a seal with tissue while inserted. Generally, a device is provided having a rigid elongate surgical access member with a lumen extending therethrough that is configured to receive a surgical tool. The device can also include a flexible sleeve having a lumen extending therethrough that is configured to receive the elongate surgical access member. A substantially rigid collar is provided disposed adjacent to a proximal end of the flexible sleeve and having a lumen extending therethrough that is configured to receive the elongate surgical access member.

  • Patent number: 7491206
    Abstract: An adjustable drill guide is provided that can be used to deliver a cross pin at a distance near the entrance to the femoral bone tunnel during ligament surgery. The cross pin positioned at the joint line, or tunnel opening, compresses and secures the graft within the bone tunnel, thereby preventing the graft from swaying back and forth post surgery when the joint is in motion. The adjustable drill guide assembly comprises a guide frame that includes an arm portion and a base portion that extends transversely to the arm portion. A rod member connects to the base portion for extending into the hone tunnel of the bone. Also included is a guide member configured for connection to the arm portion. The guide member is configured to be in moveable and lockable disposition along a length of the arm portion.

  • Patent number: 7056340
    Abstract: A method for fixing a portion of a piece of tissue in a bone tunnel comprising the steps of placing the portion of a piece of tissue in the bone tunnel, advancing spaced-apart first and second metal wires though the bone, transversely of the bone tunnel, so as to intersect the bone tunnel and extend into the portion of a piece of tissue, removing one of the wires and replacing the one removed wire with a first rod, and removing the other of the wires and replacing the other removed wire with a second rod, whereby to retain the portion of a piece of tissue in the bone tunnel with the rods.
