  • Publication number: 20070123921
    Abstract: A method for excising a portion of an articular surface using a retrograde procedure. An access tunnel is provided extending through a bone and to the articular surface. A central shaft is inserted through the access tunnel to the articular surface and a cutter is coupled to the central shaft. The cutter is coupled to the central shaft to allow the cutter to rotate with the central and to allow the cutter to be tiltable relative to the central shaft. The cutter is rotated and a retrograde force is applied to the cutter to urge the cutter into the articular surface.

  • Publication number: 20070118136
    Abstract: A tibial resurfacing system is provided that includes a drill guide, bone chisel and implant. In one aspect, the system includes a drill guide that includes a targeting ring that is shaped to be placed on the superior tibial surface and a bore section that is connected to the ring to create an axis through the tibia to the superior tibial surface in the vicinity of the targeting ring. The drill guide permits a drill pin and/or drill to be advanced through the tibia to the superior tibial surface. In another aspect, a bone chisel is provided that includes an elongated tubular structure having a first end and a bone-cutting end, and the bone-cutting end is terminated in a transverse angle thereby creating an elliptical bone-cutting face. In another aspect, an implant is provided that includes an angled bearing element formed of a cylindrical member having a first end and a second end.

  • Publication number: 20050154398
    Abstract: A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface.

  • Patent number: 6165184
    Abstract: Systems, methods, and miniature instruments are disclosed for minimally invasive surgical procedures. A miniature surgical instrument can be inserted directly into a body cavity through a cannula in a way that a surgeon can insert his or her hand into the cavity through a separate minimal incision and use the miniature instruments. A miniature surgical system can include: a cannula having a hollow body configured to receive a miniature surgical instrument and a tether connected to the instrument; and a plunger sized to engage a proximal end of the body and including a conduit therethrough for receiving the tether. The system can also include the tether and the instrument. During use, the instruments can be quickly and safely removed from the body cavity to enable the surgeon to use his or her fingers, e.g., to manipulate tissue.
