  • Publication number: 20140343012
    Abstract: Compositions and methods are provided for treating joint conditions, such as osteoarthritis and/or the pain associated therewith. The compositions and methods utilize a first component, namely hyaluraonic acid (“HA”), in combination with a lyophilized second component that is effective to at least temporarily reduce the viscosity of the HA. In an exemplary embodiment, the second component is one or more glycosaminoglycans (“GAG”), such as chondroitin sulfate (“CS”), including CS4 and/or CS6, dermatan sulfate, heparin, heparan sulfate, and keratan sulfate.

  • Publication number: 20140163695
    Abstract: A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present invention comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the body for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passageway to effect delivery of the tissue scaffold through the insertion tube.

  • Patent number: 8691259
    Abstract: A biocompatible tissue repair stimulating implant or “scaffold” device is used to repair tissue injuries, particularly injuries to ligaments, tendons, and nerves. Such implants are especially useful in methods that involve surgical procedures to repair injuries to ligament, tendon, and nerve tissue in the hand and foot. The repair procedures may be conducted with implants that contain a biological component that assists in healing or tissue repair.

  • Publication number: 20140088038
    Abstract: Compositions and methods are provided for treating joint conditions, such as osteoarthritis and/or the pain associated therewith. The compositions and methods utilize a first component, namely hyaluronic acid (“HA”), in combination with at least one stabilizer. The composition can include a stabilizer that increases the stability and shelf-life of the HA. In another embodiment, the compositions and methods can also include an additional component, such as one or more glycosaminoglycans (“GAG”) or GAG precursors. Examples of GAGs or GAG precursors can include chondroitin sulfate (“CS”), dermatan sulfate, heparin, heparan sulfate, keratan sulfate, and glucosamine (“GlcN”).

  • Patent number: 8641775
    Abstract: Biocompatible tissue implants are provided for repairing a tissue injury or defect. The tissue implants comprise a biological tissue slice that serves as a source of viable cells capable of tissue regeneration and/or repair. The biological tissue slice can be harvested from healthy tissue to have a geometry that is suitable for implantation at the site of the injury or defect. The harvested tissue slice is dimensioned to allow the viable cells contained within the tissue slice to migrate out and proliferate and integrate with tissue surrounding the injury or defect site. Methods for repairing a tissue injury or defect using the tissue implants are also provided.

  • Patent number: 8637066
    Abstract: A biocompatible ligament repair implant or scaffold device is provided for use in repairing a variety of ligament tissue injuries. The repair procedures may be conducted with ligament repair implants that contain a biological component that assists in healing or tissue repair. The biocompatible ligament repair implants include a biocompatible scaffold and particles of viable tissue derived from ligament tissue or tendon tissue, such that the tissue and the scaffold become associated. The particles of living tissue contain one or more viable cells that can migrate from the tissue and populate the scaffold.

  • Patent number: 8562542
    Abstract: A biological tissue collection device is provided having a housing with a fluid-retaining inner chamber adapted to retain a bioimplantable, fluid permeable tissue scaffold. The scaffold is preferably retained in the housing in such a way that the scaffold separates the fluid-retaining inner chamber into a first chamber and a second chamber. The collection device further includes a driver mechanism coupled to the housing and effective to create a force within the housing to displace fluid disposed within the second chamber to the first chamber. As the fluid is displaced, any biological tissue deposited on the tissue scaffold is dispersed within the fluid. Removal of the force enables the fluid to return to the second chamber and thereby deposit the tissue onto the tissue scaffold. In an exemplary embodiment, the tissue is deposited evenly onto the tissue scaffold.
