    摘要: Disclosed are products having animal tissue packed within the lumen of a device such as a needle cannula and being therein impregnated with a cryopreservation medium. The needle cannula or other device can be received in a capsule and/or other container, which in some forms can contain additional amounts of the cryopreservation medium occurring external of the lumen. Methods of use of the products are also described and can include ejecting the animal tissue from the lumen of device using pressurized liquid passed through the lumen, potentially to deliver the animal tissue directly into a patient. Methods of manufacture of the products are also described.

    摘要: Described are packaged, sterile medical graft products containing controlled levels of a growth factor such as Fibroblast Growth Factor-2 (FGF-2). Also described are methods of manufacturing medical graft products wherein processing, including sterilization, is controlled and monitored to provide medical graft products having modulated, known levels of a extracellular matrix factor, such as a growth factor, e.g. FGF-2. Preferred graft materials are extracellular matrix materials isolated from human or animal donors, particularly submucosa-containing extracellular matrix materials. Further described are ECM compositions that are or are useful for preparing gels, and related methods for preparation and use.

    摘要: Described are embodiments of a multilaminate or multiple layer implantable surgical graft with an illustrative graft comprising a remodelable collagenous sheet material, the graft including one or more interweaving members to stitch together the graft to help prevent the layers from delaminating or separating during handling and the initial stages of remodeling. The interweaving members may comprise lines of suture, thread, individual stitches, strips of material, etc. that are woven through the layers of biomaterial in a desired pattern. In one embodiment, the interweaving members comprise a pharmacologically active substance, such as a drug, growth factors, etc. to elicit a desired biological response in the host tissue. In another embodiment, the graft further comprises a reinforcing material, such as a synthetic mesh, within the layers of remodelable biomaterial and stitched together by one or more interweaving members.
