  • Publication number: 20010051816
    Abstract: The invention disclosed is a device for locking a suture in place without the need for tying knots once the suture is placed within tissue. The device comprises a locking ring, the locking ring comprising a series of laminated sheets having an aperture formed to allow the suture to pass when pulled in a first direction, but formed to lock the suture in place when the suture is pulled in an opposite direction.

  • Patent number: 6319271
    Abstract: The invention disclosed is a device for locking a suture in place without the need for tying knots once the suture is placed within tissue. The device comprises anchor having a front section and a rear section, a cannula extending through the front and rear sections through which the suture extends, and a locking mechanism for locking the suture within the cannula.

  • Patent number: 6306159
    Abstract: The invention disclosed is a device for repairing a soft tissue defect, particularly a defect in the meniscus of a knee. The device comprises an outer wall anchor for engaging against an outside wall of the meniscus on a first side of the defect, an inner meniscal anchor engaging an inner surface of the meniscus on a second side of the defect, the inner meniscal anchor having a locking mechanism, and a suture adjustably connecting the outer wall anchor to the inner meniscal anchor. Tension on the suture pulls the defect together and the locking mechanism then locks the suture in place.

  • Publication number: 20010023373
    Abstract: A reconstructive structure for a cartilaginous element having a plurality of superimposed layers of intestinal submucosa tissue compressed and secured together and shaped to provide a reconstructive structure having the anatomical shape of the cartilaginous element to be reconstructed is described. The method of forming the reconstructive structure includes superimposing the planar layers of the intestinal submucosa tissue, securing the layers to form a multi-layered structure and cutting the resulting multi-layered structure to the desired shape.

  • Patent number: 5922028
    Abstract: A reconstructive structure for a cartilaginous element having a plurality of superimposed layers of a small intestine submucosa compressed and secured together and shaped to provide the multilayered reconstructive element of the anatomical shape of the cartilaginous element to be constructed. The method of forming the reconstructive structure includes superimposing the planar layers of the small intestine compressing, securing and cutting to the desired shape. The superimposing is performed so as to maintain the layers substantially planar prior to compressing and securing. The method of reconstructing a cartilaginous element includes removing at least a portion, if not substantially all of the cartilaginous element, but leaving a seed portion, sculpturing the reconstructive structure to the anatomical shape of the cartilaginous element to be reconstructed; positioning the receptive element adjacent to the seed portion and securing it thereto.
