  • Patent number: 9138318
    Abstract: Implants for repairing tissue defects, such as cartilage tissue defects, and methods of their preparation and use are disclosed. A mold of a tissue defect is prepared by pressing upon the defect a substrate having shape memory, such as aluminum foil. The mold, which has contours substantially conforming to those of the defect, is removed from the defect, and tissue particles are added to the mold ex vivo. A biological carrier such as biocompatible glue is also added to the mold. The combination of tissue particles and the biological carrier thereby form an implant, which retains its shape after separation from the mold. The implant can be transferred to the tissue defect, with contours of the mold matching corresponding contours of the defect.

  • Patent number: 8801725
    Abstract: An instrument for determining the proper orientation for repairing a defect site on a tissue surface generally comprises a shaft, a plurality of probes operatively coupled to the shaft, and at least one indicator operatively coupled to the plurality of probes. The probes are configured to extend beyond a first end of the shaft and are movable relative the shaft. The at least one indicator is configured to display the displacements of the probes relative to the first end so that the displacements of the probes may be compared. A method of using the instrument when repairing a defect on a tissue surface is also disclosed.

  • Patent number: 8608759
    Abstract: Medical devices for cutting and suturing biological tissue generally include a shaft and first and second guide members each including a first portion coupled to the shaft at a first location and a second portion coupled to the shaft at a second location. The first portions are movable along the shaft relative to the second portions, and the first and second guide members define an arcuate profile and are configured to flex in response to such movement. When used to cut tissue, the medical device may further include a blade positioned between the first and second guide members. When used to suture tissue, one or more suture guides may be provided on the first guide member for directing a suture needle through tissue proximate the first guide member. Methods of repairing and replacing a meniscus using the medical devices are also provided.

  • Publication number: 20130330415
    Abstract: The invention provides a composition including isolated small living tissue particles, a method of making the tissue particles, and a method of using the composition to ameliorate a tissue defect. The tissue particles are composed of cells and their associated extracellular molecules and are sized, in certain embodiments, to be smaller than about 1 mm. Another aspect of the inventive tissue particles is the large percentage of viable cells. In certain embodiments, the tissue particles are made from cartilage and the composition may also contain additives such as adhesives, solutions, and bioactive agents.

  • Publication number: 20120003192
    Abstract: A hydrogel-forming composition is formed from a protein polymer derivative having a plurality of cross-linkable units depending therefrom, and a non-protein polymer derivative having a plurality of cross-linkable units depending therefrom, said non-protein polymer derivatives having hydrolysable units disposed between the polymer backbone of said derivative and at least some of said cross-linkable units. The use of a combination of protein and non-protein polymers provides for biodegradability of the hydrogel by hydrolysis of the hydrolysable units and/or enzymatic degradation of the proteins, along with mechanical properties such as strength and elasticity.
