Patent number: 9555166Abstract: The invention relates to a method for healing blood vessels by stimulating the formation of a confluent endothelial autologous cell layer in vivo on an implantable metallic stent having a lumen and a luminal surface, and an exterior surface. More specifically, the method includes implanting the stent with a coating in a patient in need of thereof; wherein the coating includes one or more layers of a matrix covalently adherent on said luminal and exterior surface of said stent containing one or more pharmaceutical substances on said exterior surface and a therapeutically effective amount of a single type of antibody, antibody fragments or combinations thereof being compatible to binding selectively to a specific cell surface antigen of circulating autologous endothelial progenitor cells in peripheral blood. In addition, genetically engineered endothelial progenitor cells can be captured on said luminal surface of stent in vivo, to proliferate to form rapidly a confluent endothelium in situ.Type: GrantFiled: June 5, 2015Date of Patent: January 31, 2017Assignee: OrbusNeich Medical Inc.Inventors: Michael John Bradley Kutryk, Robert John Cottone, Jr., Stephen Maxwell Rowland

Patent number: 7803183Abstract: A medical device with a coating for capturing target cells in vivo is provided. In particular, the medical device is coated with at least one layer of matrix and a layer of antibodies, antibody fragments or combinations thereof, which bind with specificity to mature or progenitor endothelial cells at various developmental stages to form an endothelial cell layer on the surface of the device. The coated medical device can be, for example, a stent or a synthetic graft and is useful in therapy of diseases such as restenosis, atherosclerosis, and thromboembolic complications.Type: GrantFiled: April 26, 2004Date of Patent: September 28, 2010Assignee: OrbusNeich Medical, Inc.Inventors: Michael John Bradley Kutryk, Robert John Cottone, Jr., Stephen Maxwell Rowland

Patent number: 7037332Abstract: A medical device coated with one or more antibodies and one or more layers of a matrix is disclosed. The antibodies or fragments thereof react with an endothelial cell surface antigen. Also disclosed are compositions and methods for producing the medical device. The matrix coating the medical device may be composed of a synthetic material, such as a fullerene, or a naturally occurring material. The fullerenes range from about C60 to about C100. The medical device may be a stent or a synthetic graft. The antibodies promote the adherence of cells captured in vivo 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 cells differentiate and proliferate on the medical device. The antibodies may be different types of monoclonal antibodies.Type: GrantFiled: March 15, 2001Date of Patent: May 2, 2006Assignee: Orbus Medical Technologies, Inc.Inventors: Michael John Bradley Kutryk, Robert John Cottone, Jr., Stephen Maxwell Rowland

Publication number: 20050043787Abstract: 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.Type: ApplicationFiled: April 26, 2004Publication date: February 24, 2005Inventors: Michael John Bradley Kutryk, Robert John Cottone, Stephen Maxwell Rowland

Publication number: 20040039441Abstract: A drug eluting medical device is provided for implanting into vessels or luminal structures within the body of a patient. The coated medical device, such as a stent, vascular, or synthetic graft comprises a coating consisting of a controlled-release matrix of a bioabsorbable, biocompatible, bioerodible, biodegradable, nontoxic material, such as a Poly(DL-Lactide-co-Glycolide) polymer, and at least one pharmaceutical substance, or bioactive agent incorporated within the matrix or layered within layers of matrix. In particular, the drug eluting medical device when implanted into a patient, delivers the drugs or bioactive agents within the matrix to adjacent tissues in a controlled and desired rate depending on the drug and site of implantation.Type: ApplicationFiled: May 20, 2003Publication date: February 26, 2004Inventors: Stephen Maxwell Rowland, Ike Juman, Robert John Cottone, David Lawrence Camp
