One embodiment provides a nanofibrous biocomposite material formed as a discrete textile fabric from a prepared liquid admixture of (i) a non-biodegradable durable synthetic polymer; (ii) a biologically active agent; and (iii) a liquid organic carrier. These biologically-active agents are chemical compounds which retain their recognized biological activity both before and after becoming non-permanently bound to the formed textile material; and will become subsequently released in-situ as discrete freely mobile agents from the fabric upon uptake of water from the ambient environment.Type: ApplicationFiled: June 2, 2014Publication date: September 18, 2014Applicants: BioSurfaces, Inc., Clemson University, Rhode Island Board of EducationInventors: Matthew D. Phaneuf, Philip J. Brown, Martin J. Bide

Patent number: 8821958Abstract: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.Type: GrantFiled: August 30, 2012Date of Patent: September 2, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: Cameron K. Kerrigan, Stephen D. Pacetti
