    摘要: Devices and methods for reducing, eliminating, preventing, suppressing, or treating tissue responses to hemostatic devices e.g., biological sealants or vascular procedures are disclosed. The invention employs a combination of resorbable, biocompatible matrix materials and a variety of therapeutic agents, such as antiproliferatives or antibiotics, applied to a vascular puncture or incision to achieve hemostasis following diagnostic or interventional vascular catheterizations and to treat neointimal hyperplasia and stenosis. A matrix of a material such as collagen provides a reservoir of a therapeutic agent such as rapamycin (sirolimus) and its derivatives and analogs for delivery at a tissue site at risk for vasculoproliferation, infection, inflammation, fibrosis or other tissue responses.

    摘要: A method for percutaneous sealing of punctures in arterial and venous blood vessels is provided. After catheterization of any vessel or organ for diagnostic or interventional procedures or endoscopic or orthopedic procedures involving the intentional puncture and penetration of a vessel wall, or the accidental puncture of a vessel wall, separate solutions containing fibrinogen and thrombin, respectively, are introduced into the tissue surrounding the puncture site. The solutions are allowed to mix forming a semisolid gel at the time of application at the puncture site. The gel further hardens around the site to seal the puncture closed preventing the leakage of blood. Solutions of antibiotics and epinephrine as well as agents that slow clot breakdown may be included in the mixture. An apparatus for accomplishing the method is also disclosed.

    摘要: Administration of a formulation comprising a antirestenotic compound conjugated to a microparticle carrier is effective to inhibit stenosis formation in a blood vessel. Such stenosis typically results, in the absence of treatment, from trauma to a vessel, such as an incision, excessive pressure, an angioplasty procedure and/or stent implantation. The antirestenotic compound is typically an antiproliferative, immunosuppressive, or antiinflammatory drug, such as rapamycin, tacrolimus, paclitaxel, dexamethasone, or an active analog or derivative, an antisense oligonucleotide, or combinations thereof. The microparticle carrier comprises a suspension of gas-filled microbubbles or biocompatible polymeric microparticles, in a pharmaceutically acceptable liquid vehicle, and is effective to deliver the conjugated therapeutic to the site of vessel injury.

    摘要: The invention disclosed herein relates to methods and compositions useful for the production of composites for bone implantation. The invention includes methods for production of lyophilized bone fragments seeded with lyophilized stem cells, mesenchymal stem cells, bone marrow stem cells, periosteal cells or osteocytes that are derived either from the recipient of the bone implant or from allogeneic sources. The methods of the invention comprise production of bone implant material including the steps of cutting solid bone into fragments, decellularizing the bone fragments, seeding stem cells, mesenchymal stem cells, bone marrow stem cells, periosteal cells or osteocytes onto the decellularized bone fragments and lyophilizing the complex of bone fragments and cells. The stabilized bone matrix and complex of bone and cells increases the ease of transport, storage and reconstitution of bone and cells for bone implantation.

    摘要: A method and system of embolizing an organ or vessel is disclosed. An embolization device such as a coil, balloon, spheres, stents or occlusive plaques is used. The embolization device has a surface, which may be coated with composition retaining material such as a polymer, bio-polymer or non-polymer based technology that allows sustained release of drug or material from drug eluting occlusive device. For example, an anti-angiogenic composition is coated on the application surface. The embolization device is then inserted in the vessel and embolization is enhanced by the composition.
