Title: Knee computer-aided navigation instruments
Inventor: WALSH GEAROID
IPC: A61B17/15
Filed: 2004-12-09
Abstract: A bone cutting guide block has a saw guide surface thereon and has a body shaped to conform to the anterior-medial shape of the proximal left tibia and distal left femur and also to the anterior-lateral shape of the proximal right tibia or the distal right femur. The block is used by placing the curved inner surface adjacent the anterior-medial or anterior-lateral quadrant of either the tibia or the femur and utilizing images from a computer database utilizing an optical tracking system mounted on the cutting block and referencing to the bone to be cut. Utilizing the tracking system, the cutting guide is positioned preferably by hand in the proximal-distal direction to set the depth of the resection. The cutting guide surface is then oriented by hand to the correct varus-valgus and/or flexion-extension angles and pinned to the bone. Preferably, the block is pinned using a single pin in either the correct varus-valgus or flexion-extension position and then the other of the angles not initially selected is set by rotating the block about the single pin. Once the other of the varus-valgus or flexion-extension angles is determined, additional pins are utilized to fix the guide in position for use during the resection of the proximal tibia or distal femur. A second block is provided conforming to the anterior-lateral left tibia and femur as well as the anterior-medial shape of the right tibia and femur.

Abstract: An implantable prosthesis (21) for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch (22) and/or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness. At least one tether (24), such as a strap, extends from the patch or plug and may be manipulated by a surgeon to position the patch or plug relative to the repair site and/or to secure the patch or plug relative to the opening or weakness in the tissue or muscle wall. The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and/or manipulate the patch from a location outside the body. An indicator (60) may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A  support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and/or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and/or positioning of the patch or plug over the opening or weakness.
