  • Patent number: 9320829
    Abstract: A medical device for implantation into vessels or luminal structures within the body is provided, which stimulates positive blood vessel remodeling. The medical device, such as a stent and a synthetic graft, is provided with a coating with a pharmaceutical composition containing a controlled-release matrix and one or more pharmaceutical substances for direct delivery of drugs to surrounding tissues. The coating on the medical device further comprises one or more barrier layers, and a ligand such as a peptide, an antibody or a small molecule for capturing progenitor endothelial cells in the blood contacting surface of the device for restoring an endothelium at the site of injury. In particular, the drug-coated stents are for use, for example, in balloon angioplasty procedures for preventing or inhibiting restenosis.

  • Patent number: 8808365
    Abstract: Biocompatible materials for use in vascular applications or for implantation have been engineered, combining human recombinant tropoelastin with other synthetic or natural biomaterials to form protoelastin. The materials can be in the form of elastin films on metal or polymer substrates, laminates of alternating polymer and elastin, blends of polymer and elastin, or elastin crosslinked with or tethered to polymer or metal. These are mechanically stable, elastic, strong and biocompatible (i.e., not thrombogenic and promoting adhesion of cells, especially human endothelial cells), not eliciting a foreign body response. Plasma polymerization of substrate is shown to enhance biocompatibility, especially when used to bind elastin or other protein to the substrate.

    Abstract: An endovascular graft, having both an expandable stent portion and a stent cover portion positioned, the graft itself and/or a stent cover-portion coated with a bioactive agent adapted to promote initial thrombus formation, preferably followed by long term fibrous tissue ingrowth. The endovascular graft prevents endoleaking by promoting a short term hemostatic effect in the perigraft region. This short term effect can, in turn, be used to promote or permit long term fibrous tissue ingrowth. Particularly where the stent cover portion is prepared from a porous material selected from PET and ePTFE, the bioactive agent can include a thrombogenic agent such as collagen covalently attached in the form of a thin, conformal coating on at least the outer surface of the stent cover. An optimal coating of this type is formed by the activation of photoreactive groups.

  • Patent number: 6579322
    Abstract: A novel biomedical material, which is characterized by coating a genetically engineered CBD-RGD peptide layer on the surface of a biomedical material consisting of PU to improve the attachment of tissue cells, such as fibroblasts, epithelial cells and endothelial cells. A modified artificial vessel is also disclosed, wherein the adherence of endothelial cells is enhanced by coating a genetically engineered CBD-RGD containing peptide layer on the inner surface of the artificial vessels pre-modified by cross-linked gelatin, and the adhering capacity and activation of platelets is reduced.

  • Patent number: 6410044
    Abstract: A crosslinkable macromer system and related methods of preparing the system and using the system in the form of a crosslinked matrix between a tissue site and an implant article such as a tissue implant or on the porous surface of a prosthetic device. The macromer system includes two or more polymer-pendent polymerizable groups and one or more initiator groups (e.g., polymer-pendent initiator groups). The polymerizable groups and the initiator group(s), when polymer-pendent, can be pendent on the same or different polymeric backbones. The macromer system provides advantages over the use of polymerizable macromers and separate, low molecular weight initiators, including advantages with respect to such properties as nontoxicity, efficiency, and solubility. A macromer system of the invention can be used as an interface between the tissue site and implant article in a manner sufficient to permit tissue growth through the crosslinked matrix and between the tissue site and implant.

  • Publication number: 20020049495
    Abstract: This invention provides compositions and methods for producing a medical device coated with a matrix and an antibody which reacts with an endothelial cell antigen. The matrix coating the medical device may be composed of synthetic material, such as polyurethane, poly-L-lactic acid, cellulose ester or polyethylene glycol. In another embodiment, the matrix is composed of naturally occurring materials, such as collagen, fibrin, elastin, amorphous carbon. In a third embodiment, the matrix may be composed of fullerenes. The fullerenes range from about C60 to about C100. The medical device may be a stent or a synthetic graft. The antibodies promote adherence of endothelial cells on the medical device. The antibodies may be mixed with the matrix or covalently tethered through a linker molecule to the matrix. Following adherence to the medical device, the endothelial cells differentiate and proliferate on the medical device. The antibodies may be different types of monoclonal antibodies.

  • Patent number: 6368347
    Abstract: A vascular graft comprised of a tubular polytetrafluoroethylene (ePTFE) sheet. The ePTFE sheet has a substantially uniform coating of bioresorbable gel material on an outer surface. The coating minimizes bleeding through suture holes in the ePTFE sheet and an increase in longitudinal extensibility.
