A biologic material is disclosed. The biologic material comprises a crosslinked structural protein and macrophages seeded on the crosslinked structural protein. A method of use of the biologic material for an immunoregenerative treatment in a patient in need thereof also is disclosed. The method comprises steps of: (1) seeding the macrophages on the crosslinked structural protein, thereby obtaining the biologic material; and (2) implanting the biologic material into the patient.

A microstructured hemostat comprising multiple layers of microstructure, each layer characterized by one or more length scales, is described. Microstructured hemostats of the present invention, can reduce the time for blood coagulation, control the morphology of the coagulation, and provide a novel diagnostic platform for evaluation of coagulation function from a morphological perspective.

In some aspects, the present invention provides surgical procedures that comprise applying compositions into and/or onto tissue, including supporting tissues (e.g., ligaments, connective tissue, muscles, etc.) for pelvic organs, among other tissues. In other aspects, the present disclosure pertains to compositions that are useful for performing such procedures. In still other aspects, the present disclosure pertains to kits that are useful for performing such procedures.

An implantable medical device for implantation in a mammal joint having at least two contacting surfaces is provided. The medical device comprises; an artificial contacting surface adapted to replace at least the surface of at least one of the mammal's joint contacting surfaces, wherein the artificial contacting surface is adapted to be lubricated, when implanted in said joint. Furthermore the medical device comprises at least one inlet adapted to receive a lubricating fluid from a reservoir, at least one channel at least partly integrated in the artificial contacting surface in connection with the at least one inlet for distributing the lubricating fluid to the surface of the artificial contacting surface. The medical device could be adapted to be operable by an operation device to receive the distributed lubricated fluid from a reservoir.

An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a substrate formed from a first material and a second material. At least one of the first and second materials includes a hemostatic agent. Kits, systems and methods are disclosed.

This tissue-joining member comprises non-crosslinked fibrous collagen. A laminate body comprises: a support; a joining member that is layered on one surface of the support; and a first adhesive layer that is layered on said one surface of the support in a region on which the joining member is not layered. The method for using the joining member or the laminate body comprises: a heating step in which the joining member or the laminate body is heated to less than 60° C. and greater than body temperature after having being layered on the tissue; and a cooling step in which the heated joining member or laminate body is cooled to body temperature or lower. A treatment system comprises a heating unit and the joining member or the laminate body.

Methods and systems for stiffening of tissue are presented to allow improved processing. Solutions including an acid or a base can be contacted with tissue to stiffen one or more components of the tissue. The resulting stiffened tissue can be used in the creation of wound treatment devices.

A flexible anchor for coupling a suture to a bone is provided. The anchor is composed of non-woven electrospun fibers and has an elongate tubular body that extends from a first end to a second end. The anchor is configured to receive a suture that enters the anchor through a first aperture and exits the anchor through a second aperture. When free ends of the suture are pulled, the anchor transitions from a first configuration to a second anchoring configuration.

The methods and compositions described herein address the need in the art by providing peptides and polypeptides comprising a growth factor binding domain. In some embodiments, the peptides have an amino acid sequence that is at least 80% identical to one of SEQ ID NOS:1-7, 13-15, 49-50, or 66-70, or a fragment thereof; wherein the peptide is less than 300 amino acids in length.

A suture anchor for tissue repair that has a proximal section and a main section where the proximal and main sections are formed of different materials. The proximal section is formed of a material that promotes in-growth from the surrounding tissue.
