BIOABSORBABLE TEXTILES AND METHODS FOR JOINT FUNCTION RESTORATION
A bioabsorbable textile for the restoration of the joint function whereas the joint is affected by partial thickness tears, small to medium full-thickness tears, large to massive full-thickness tears, acute and chronic/degenerative tears. The bioabsorbable textile may comprise polymeric yarns interconnected to form a weave or knitted configuration, wherein said bioabsorbable textile provides a combined mechanical and biological augmentation in the target joint tissue. The bioabsorbable textile may be implanted in combination with fixation tools during open, mini-open or arthroscopic repair/augmentation procedures of joint tissue tears.
AN ATTACHMENT MEANS FOR ATTACHING A MEDICAL DEVICE TO TISSUE, A SYSTEM FOR ATTACHING A MEDICAL DEVICE TO TISSUE, A MEDICAL DEVICE HAVING AN ATTACHMENT MEANS, A METHOD OF ATTACHING A MEDICAL DEVICE TO TISSUE, AND A METHOD OF MANUFACTURING AN ATTACHMENT MEANS
An attachment device for connecting a medical device to biological tissue of a subject includes a biocompatible scaffold including photoactive crosslinking agent and a photoactive dye to facilitate crosslinking of the scaffold with biological tissue of a subject when light is directed onto the scaffold. A conformable cover for a medical device made from the biocompatible scaffold includes strain crystallised, filaments which change shape at a predetermined temperature to conform the cover to an outer shape of the medical device. The conformable cover can be attached to biological tissue.

Compositions and methods for promoting bone regeneration
This invention relates to compositions and methods for promoting and/or accelerating bone regeneration, repair, and/or healing and, in particular, to compositions and methods of promoting bone regeneration, growth, repair, and/or healing using graft or scaffold materials. In exemplary embodiments, the disclosed compositions may be used to promote and/or accelerate bone regeneration by delivering a composition to a bone site, the composition comprising (a) a citrate component, (b) a phosphate component, and, optionally, (c) a particulate inorganic material. The citrate component and/or phosphate component is advantageously released from the composition at the bone site. The released citrate component may function to increase alkaline phosphatase activity and/or expression at the bone site, and the increased alkaline phosphatase activity and/or expression may release the phosphate component. The composition may be delivered in various forms, e.g., as a biodegradable scaffold.
NON-FIXED TYPE IMPLANT FOR CRANIOTOMY AND METHOD OF MANUFACTURING SAME
Proposed is a non-fixing implant made of a raw material including a biomaterial and a ceramic-based composite material having excellent osteoconductivity in addition to a polymer. The non-fixing implant can be accurately secured to a gap between the skull and the bone flap and can be conveniently used. Further proposed is a method of manufacturing the non-fixing implant. The non-fixing implant includes a flexible wedge deformable to conform to the external contour of the bone flap and a plurality of wings connected to an upper or lower portion of the flexible wedge and extending to both sides of the flexible wedge. The wings have a porous structure. The wings on one side will be positioned on the bone flap and the wings on the other side will positioned on the skull. The non-fixing implant has the advantage of being capable of accurately filling a defect formed by craniotomy, has improved biocompatibility and bone bonding ability, and allows tissue invasion.
SYSTEMS, METHODS, AND DEVICES INCLUDING A DEMINERALIZED BONE MATRIX (DBM) GRAFT WITH GELATIN CARRIER
Systems, methods, and devices include techniques for generating and using a demineralized bone matrix (DBM)-gelatin matrix allograft material. The DBM-gelatin material can be used to form an implant (e.g., for sternal closure operations) and/or a gel (e.g., for wound/fracture treatment). A method for forming the implant or bone graft can include forming the DBM from an initial bone material; and mixing, in a solution, the DBM with a gelatin carrier to form a DBM-gelatin solution. The gelatin carrier can include an animal-based collagen, such as a porcine-based collagen or a bovine-based collagen. Additionally, the method of forming the bone graft can include performing a crosslinking reaction with the DBM-gelatin solution. The implant can be packaged in a sterile hydration container prior to use.
