  • Publication number: 20040087981
    Abstract: A tissue fastener comprises a shaft having a member disposed thereon for lodging the shaft within the tissue, the shaft having a region that is relatively flexible to render a tissue engaging head disposed at a proximal end of the shaft movable with respect to the shaft. In one embodiment, the region comprises substantially an entire length of the shaft and is made from flexible material, such as a mesh, onto which the member and the head are molded. In another embodiment, the shaft comprises generally rigid material, and the region comprises a flexible joint between the shaft and the head. The flexible joint comprises a breakable (e.g., frangible) section of the shaft, and a flexible member (e.g., a plurality of filaments or a flexible tube) extends between the shaft and the head past the breakable section.

  • Patent number: 6358253
    Abstract: A method of repairing cartilage (e.g., articular cartilage on the femur) and a set of instruments used in the method are provided. The damaged cartilage is removed from the bone to expose the underlying bone, grafts covered with cartilage (e.g., hyaline cartilage) are harvested from elsewhere in the body (e.g., other areas of the femur), and the grafts are inserted into holes drilled into the exposed area of bone. A guide is provided for use with surgical instruments during the procedure to orient the surgical instruments perpendicularly to the bone surface during use. The guide includes a guiding portion disposed along a longitudinal axis for engaging the surgical instrument, and a tissue-engaging portion oriented perpendicularly to the longitudinal axis. A set of surgical instruments used to carry out the method includes the guide, a drill for forming the graft-receiving holes, and an insertion tool for inserting the grafts. Other accessory instruments are also provided.

  • Publication number: 20020019649
    Abstract: A method of closing a tissue wound includes providing a wound closure device having a first anchor, a second anchor, and a flexible member movably attached to the second anchor, positioning the first anchor against tissue, passing the flexible member across the wound, positioning the second anchor against tissue, and pulling on a free end of the flexible member to shorten a length of the flexible member between the first and second anchors, thereby closing the wound. A wound closure device includes a first anchor, a second anchor; and a flexible member connecting the first anchor to the second anchor, the flexible member being movably attached to the second anchor, such that pulling on a free end of the flexible member shortens a length of the flexible member between the first and second anchors.

  • Patent number: 5782834
    Abstract: A surgical instrument in which a surgical tool is carried distally of a bend region in a stationary support member by an assembly that transmits proximally applied forces through the bend region to both operate the surgical tool and selectively change the rotational orientation of the surgical tool with respect to the stationary member. In another aspect, in which the stationary member does not include a bend region, a rotatable member supported by the stationary member transmits rotational force to the surgical tool to selectively change the rotational orientation of the tool, and a driver member supported by the stationary member transmits axial force to the surgical tool to operate it.

  • Patent number: 5667513
    Abstract: A soft tissue anchor delivery apparatus includes a gripping device having fingers at the distal end and configured such that they can hold a soft tissue anchor about the head portion of the anchor. An actuating tube slides over the gripper and the fingers, thus holding the fingers and the contained soft tissue anchor within the bore of the actuating tube. A pushrod is placed within the bore of the gripper. The pushrod has a countersunk head that is shaped such that it is a close fit for the head of the soft tissue anchor. The pushrod is connected to a tube having a bore so that the actuating pin of the soft tissue anchor can be pushed down into the head of the anchor. The pushrod is spring loaded so as to allow the pushrod to be driven distally upon retraction of the actuating tube, thus driving the anchor free of the deployed fingers and hence of the entire delivery system.

  • Patent number: 5608934
    Abstract: An apparatus and method for positioning a leg during surgery has a support for holding a substantial portion of one of the patient's legs on the side facing the other leg and a pivot located in the proximity of the patient's pelvis. After patient's pelvis is secured relative to the operating table, the distal end of the support can be moved for adjustment of the outer extremity of the patient's leg relative to the operating table to selectively position the leg relative to the patient's pelvis.

  • Patent number: 5601558
    Abstract: A soft tissue anchor implantation device having a bore along its longitudinal axis through which a guiding K-wire or other guiding devices may be freely drawn, and into which an anchor expanding pin may be wedged to expand the anchor body and lodge it securely in a hole in a bone. In one embodiment the anchor has an elongated body with proximal and distal ends. The proximal end is supplied with an enlarged head having an underside equipped with downwardly extending spikes for gripping soft tissue.

  • Patent number: 5380334
    Abstract: Surgical kits for the implantation of soft tissue-to-bone anchors and expandable, preferably bioabsorbable, soft tissue anchors. The surgical kits include an embodiment with an outer tube with an expandable anchor releasably attached to its distal end, for guiding the anchor into a predrilled hole; an inner tube with an anchor expanding pin sized for expanding the anchor releasably held in its bore; and a pushrod for pushing the anchor pin into the anchor to expand it and wedge it in a hole. In an alternative embodiment, the anchor pin is attached to the distal end of a pushrod inserted into an outer tube. In one embodiment, the anchor is equipped with downward extending spikes on the underside of an enlarged head for gripping soft tissue and bending barbs to resist withdrawal of the anchor from bone. In another embodiment, the anchor's proximal end has no enlarged head but is equipped with sutures.
