Patent number: 8252878Abstract: A novel class of polymers obtainable by copolymerising a monomer mixture comprising (i) hydrophilic monomer of general formula (I) Y—B—X; (ii) styrene or a substituted styrene, a monomer or mixture of monomers which when polymerized form a polymer with a Tg lower than the Tg of a homopolymer of monomer (I) and lower than the Tg of a homopolymer of monomer (ii); and a monomer having a crosslinkable group is described. The invention also relates to a method for producing such polymers, implants coated with the polymers and methods for forming the same.Type: GrantFiled: July 16, 2007Date of Patent: August 28, 2012Assignee: Biocompatibles UK LimitedInventors: Andrew Lennard Lewis, Sean Willis, Stephen Alister Jones, Vincent James O'Byrne, David Michael Grey, Michael John Driver, Samantha Ryan, Richard Paul Redman

Patent number: 8052746Abstract: The present invention relates to a balloon expandable stent mounted on a balloon catheter, the entire assembly being overcoated with a coherent polymer coating, which is preferably substantially continuous over the circumference and, more preferably, axial length of the stem on the balloon. The polymer coating improves retention of the stent on the balloon during delivery and does not adversely effect the deployment characteristics, nor the balloon failure characteristics. The product is made by mounting the stent on the balloon and coating the assembly with a liquid coating composition containing a suitable polymer followed by curing of the coating. The polymer is biocompatible and preferably crosslinkable in the coating composition, and crosslinked in the final product. A suitable polymer is formed from monomers including a zwitterionic, preferably a phosphoryl choline, group, and monomers including a trialkoxysilyl group.Type: GrantFiled: July 23, 2007Date of Patent: November 8, 2011Assignee: Biocompatibles LimitedInventors: Peter William Stratford, Alistair Stewart Taylor, Vincent James O'Byrne, John Tom Clarke, Denis Dominic Healy

Publication number: 20090317443Abstract: A method forming a coated implant is described. The implant comprises a surface which is first coated with a primer and subsequently with a biocompatible polymer capable of forming a covalent bond to the primer. The polymer coating is then crosslinked. The invention also relates to implants, in particular, stents, coated with such a coating.Type: ApplicationFiled: July 16, 2007Publication date: December 24, 2009Applicant: BIOCOMPATIBLES UK LIMITED Chapman HouseInventors: Sean Willis, Vincent James O'Byrne, Samantha Ryan
