Abstract: This invention relates to a device and method therefor used in osteotomy for removing a right-angled bone wedge from a leg bone. The device consists of a trapezoidal block with a detachable connecting member which is used with detachable towers and surgical pins that allows the surgeon to establish a reference external to the bone as to the position of the apex and angle of the wedge to be cut and then to drill the surgical pins into the leg bone to secure the block in position. The block includes integral saw guides having interconnected upper and lower guide slots to translate the reference into the bone as saw cuts which precisely remove the required wedge of bone. The connecting member is then detached and the block and pins removed to allow completion of the surgical procedure.

Abstract: This invention relates to a device and method therefor used in osteotomy for removing a right-angled bone wedge from a leg bone. The device consists of a trapezoidal block having one column of transverse bores and other columns of oblique bores. The columns of oblique bores are positioned at predetermined angles from the column of transverse bores. A first tower member is mounted atop the block. The first tower also has a plurality of transverse bores that align with the transverse bores in the block. A surgical pin can be inserted through the tower until the tip of this pin lies above the apex of the bone wedge to be cut. Surgical pins are then inserted through the corresponding transverse bores in the block and drilled into the bone until the ends of these pins align with the end of the first pin inserted in the first tower. This procedure establishes the height of the bone wedge. A second tower is coupled to an oblique bore at the desired predetermined angle.

Abstract: An osteotomy device and method therefor, is provided that allows the surgeon to establish a reference external to the bone as to the position of the apex and angle of the wedge to be cut and then to make use of an integral saw guide to translate those references into the bone as saw cuts which precisely remove the required wedge of bone. Thus this device and method therefor would enable the surgeon to leave a sufficient amount of residual bone after making the cuts into the bone (for example of a wedge of bone) so as to inhibit the fracturing of the bone.

Surgical pins are then inserted through the corresponding transverse bores in the block and drilled into the bond until the ends of these pins align with the end of the first pin inserted in the first tower. This procedure establishes the height of the bone wedge. A second tower is coupled to an oblique bore at the desired predetermined angle.

Abstract: Surgical fasteners and a method for repairing a tear in body tissue using the fastener are disclosed. The fastener includes a suture and an instrument for inserting the suture. The suture has a base member for seating against the body tissue, a shaft upstanding from the base member for inserting into the tissue and across the tear, and at least one barb for locking the shaft in place, holding the sides of the tear together. The surgical fastener is particularly adapted for repairing the meniscus at the knee joint. The meniscus is prepared by removing the tip or inner edge thereof to provide a flat surface through which to insert the suture and against which to seat the base member. The suture is inserted through the prepared surface internal to the joint and is outwardly directed. The suture passes through the tear area and joins together the two sides of the tear.

Abstract: A surgical suture and a delivery system for positioning and inserting the suture is disclosed. The suture includes a base member having two substantially parallel, rigid, barbed shafts upstanding therefrom. The delivery system includes a hollow sleeve member having an elongate cross section with the long dimension of the cross section sufficient to accommodate the width of the base member. In use, the end of the hollow sleeve is positioned adjacent a body tissue wound which is to be repaired and the suture is inserted into the tissue by pushing the suture through the sleeve by means of a pusher member. If necessary, a starter member is first pushed through the sleeve to provide started openings in the tissue into which the barbed shafts are then inserted.
