Publication number: 20100036481Abstract: A material in a flowable state is applied to the interstitial pores of a radially-expandable endovascular tubular braid structure to modify the tubular braid structure for use in the treatment of cardiovascular disease. The material is cured to form a membrane at least within the coated interstitial pores. A cardiovascular device, for use in a vascular lumen within a body for treatment of cardiovascular disease, includes a braided body with electroporation means for helping prevent restenosis in a cardiovascular lumen. A method for treating cardiovascular disease includes placing a radially expandable and collapsible medical device within a cardiovascular passageway, positioning it at a target site, and placing it in a radially expanded state. Restenosis at the target site is inhibited by a chosen one of electroporation and iontophoresis. The medical device is collapsed and is then removed from the passageway.Type: ApplicationFiled: June 5, 2009Publication date: February 11, 2010Applicant: Artemis Medical, Inc.Inventors: William R.

Patent number: 7011654Abstract: A dilating and support apparatus with disease inhibitors and methods for use is disclosed that is particularly useful for repairing and/or serving as a conduit for body passageways that require reinforcement, dilatation, disease prevention or the like. Such apparatuses are utilized to deliver a therapy, that therapy being from a family of devices, drugs, or any of a variety of other elements to a specific location within the body. The instant disclosure provides a system of combining a novel radial deployment and/or drug delivery therapy with existing balloon dilatation therapy into one device. This combination will yield a significant decrease in cost to the healthcare system as well as providing a therapy to the patient with increased safety and efficacy. Further, the instant invention provides a novel and improved platform for synthetic/tissue interface between the device and the body.Type: GrantFiled: February 12, 2001Date of Patent: March 14, 2006Assignee: Artemis Medical, Inc.Inventors: William Richard Dubrul, Richard E Fulton
