  • Publication number: 20110177134
    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.

  • Publication number: 20100280406
    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.

  • Publication number: 20050130879
    Abstract: A method for modifying the surface properties of tissue in vivo is described. The method comprises forming a liquid crystalline matrix on the tissue surface wherein the matrix comprises a tissue surface component. In one embodiment there is provided a method for improving the bonding of surgical glues and cements to cartilage and other synovial fluid wetted tissue surfaces. Such surfaces are contacted with a composition comprising a poly(hydroxy substituted amino acid) to form a liquid crystalline matrix on the tissue surface. The matrix is readily removed to provide a tissue surface that exhibits improved bonding with surgical glues.

  • Publication number: 20050113736
    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.
