Patent number: 8303993Abstract: The present relates to an autologous bioadhesive sealant composition, or fibrin glue prepared by a two-phase method, wherein all of the blood components for the bioadhesive sealant are derived from a patient to whom the bioadhesive sealant will be applied. A platelet rich plasma and a platelet poor plasma are formed by centrifuging a quantity of anticoagulated whole blood that was previously drawn from the patient. In one embodiment the platelet rich plasma is divided into two portions. In phase one, a compound that reverses the effect of the anticoagulant is added to the first portion and a clot is allowed to form. The clot is then triturated, and the resulting, serum containing autologous thrombin is collected. In phase two, the serum obtained from phase one is mixed with the second portion of the-platelet rich plasma to form the bioadhesive sealant of the invention.Type: GrantFiled: June 23, 2005Date of Patent: November 6, 2012Assignee: Ateriocyte Medical Systems, Inc.Inventors: Robert F. Baugh, Lisa M. Lim, Julie S. Johnston, John G. Rivera

Patent number: 7934603Abstract: The delivery system of the present invention is comprised of at least two chambers which store, individually, an activated blood component and an inactivated blood component. The first chamber comprises an activating agent and a filter which may be one in the same thus allowing the formed clot to be triturated thereby isolating the thrombin from the clot. The second chamber stores the inactivated blood component that when mixed with thrombin will produce a gel. The first or second chamber may further contain agents which are desired to be delivered to a specific site. The unique design of the delivery system allows for ease in operation of combining two agents at a specific time and place.Type: GrantFiled: May 2, 2005Date of Patent: May 3, 2011Assignee: Arteriocyte Medical Systems, Inc.Inventors: Julie S. Eaton, Robert F. Baugh, Lisa M. Lim, John G. Rivera, Victor D. Dolecek

Patent number: 6444228Abstract: In general, the present invention relates to a two-phase method for forming an autologous bioadhesive sealant composition or fibrin glue wherein all of the blood components for the bioadhesive sealant are derived from a patient to whom the bioadhesive sealant will be applied. First, a platelet rich plasma and a platelet poor plasma are formed by centrifuging a quantity of anticoagulated whole blood that was previously drawn from the patient. The platelet rich plasma and platelet poor plasma are then divided into two portions. To the first portion, which is used in phase-one, a compound that reverses the effect of the anticoagulant is added, and a clot is allowed to form. The clot is then triturated and the resulting serum, containing autologous thrombin, is collected. The serum obtained from phase-one is then mixed with the second portion of the platelet rich plasma or platelet poor plasma, used in phase-two, to form the bioadhesive sealant of the present invention.Type: GrantFiled: April 20, 1998Date of Patent: September 3, 2002Assignee: Medtronic, Inc.Inventors: Robert F.
