Patent number: 6624262Abstract: The present invention describes preparation of nanocomposite particles and structures by polymerizing monomers onto a functional inorganic colloid comprising a polymerization initiation site. The polymerization process is preferably a controlled/living polymerization process, including but not limited to, atom transfer radical polymerization and stable free radical polymerization. The nanocomposite particles can self-organize in solution, on surfaces or in films forming nanocomposite structures. Tethered AB block nanocomposite particles bring size control, solubility control and control over micro- and macro-functionality to the particles. The process may be catalyzed by a transition metal complex which participates in a reversible redox cycle with at least one of the group and a compound having a radically transferable atom or group, to form a nanocomposite particle with a tethered polymer chain. The process may be continued to form tethered copolymer chain.Type: GrantFiled: October 5, 2001Date of Patent: September 23, 2003Assignee: Carnegie Melon UniversityInventors: Krzysztof Matyjaszewski, Nicolay Tsarevsky

Patent number: 6620170Abstract: The present invention provides devices and methods for inducing fibrin growth in tissue to promote revascularization of that tissue. The devices and methods are useful in ischemic tissue occurring anywhere in the body, and are particularly useful in treating ischemic myocardial tissue of the heart. The device may comprise a frame configured to foster a fibrin growth and configured to permit communication between the fibrin and the tissue into which the frame is implanted. The fibrin may be positioned internally or externally on the frame. The implant should be capable of becoming anchored in the tissue to prevent the formed fibrin from dislodging from the tissue. A fibrin producing substance may be associated with the implant device to help promote and sustain the fibrin growth. Alternatively, a thrombophilic or fibrin producing substance may be introduced into ischemic tissue alone, without an associated device, to induce fibrin growth in vivo.Type: GrantFiled: April 26, 1999Date of Patent: September 16, 2003Assignee: C.
