Patent number: 7879270Abstract: A process for producing a dilatation balloon by extruding a multiblock copolymer composition to form an extrudate comprising phase-separated glassy, rubber, and semicrystalline microdomains that are macroscopically ordered in a perpendicular alignment. The balloon formed by the process demonstrates, during inflation, a true stress vs. nominal strain response curve comprising a first zone representative of a low modulus balloon, a second zone representative of a high strength balloon, and a sharp transition from the first zone to the second zone.Type: GrantFiled: August 26, 2010Date of Patent: February 1, 2011Assignees: Medtronic, Inc, Regents of the University of MinnesotaInventors: Ashish Varma, Kimberly A. Chaffin, Frank Bates, Marc Hillmyer, Lisa Lim

Publication number: 20090140449Abstract: A self-wrapping dilatation balloon comprising a multiblock copolymer having high elasticity and elastic recovery from nominal strains greater than about 30% is described. Also described herein, is a polymeric extrudate for making a dilatation balloon comprising a multiblock copolymer having tensile strength in the range of about 50 MPa to about 450 MPa, strain at break in the range of about 50% to about 600% and substantially complete elastic recovery from nominal strains of at least about 30%. The extrudate has phase-separated microdomains that are macroscopically aligned in parallel, perpendicular, transverse or a combination thereof. Also described herein is a process for producing a polymeric extrudate for use as a dilatation balloon. The process comprises extruding a multiblock copolymer mixture or composition to form an extrudate.Type: ApplicationFiled: October 30, 2008Publication date: June 4, 2009Inventors: Ashish Varma, Kimberly A.

Publication number: 20050252867Abstract: Provided are methods of applying biological compositions, that is, autologous bioadhesive sealant compositions containing one or more biological agents, to an individual, wherein all the blood components used in preparing the composition are derived from the patient who is to receive the biological composition. In one embodiment, the method comprises obtaining a whole blood sample from an individual; forming an inactive platelet rich plasma from the whole blood sample; mixing a biological agent into the inactive platelet rich plasma; obtaining thrombin from the whole blood sample; mixing the thrombin into the inactive platelet rich plasma to form a biological composition; and applying the biological composition to the individual.Type: ApplicationFiled: June 23, 2005Publication date: November 17, 2005Inventors: Robert Baugh, Lisa Lim, Julie Johnston, John Rivera

Publication number: 20050209081Abstract: 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: ApplicationFiled: May 2, 2005Publication date: September 22, 2005Inventors: Robert Baugh, Lisa Lim, Julie Eaton, John Rivera, Victor Dolecek

Publication number: 20050152886Abstract: 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 present invention.Type: ApplicationFiled: December 3, 2004Publication date: July 14, 2005Inventors: Robert Baugh, Lisa Lim, Julie Johnston, John Rivera
