Patent number: 9974670Abstract: A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease can be formed as a thin, annular band of durable, flexible material. The tack device may also have a plurality of barbs or anchoring points on its outer annular periphery. The annular band can have a length in the axial direction of the blood vessel walls that is about equal to or less than its diameter as installed in the blood vessel. A preferred method is to perform angioplasty with a drug eluting balloon as a first step, and if there is any dissection to the blood vessel caused by the balloon angioplasty, one or more tack devices may be installed to tack down the dissected area of the blood vessel surface, in order to avoid the need to install a stent and thereby maintain a ‘stent-free’ environment.Type: GrantFiled: September 27, 2011Date of Patent: May 22, 2018Assignee: Intact Vascular, Inc.Inventors: Peter Schneider, Robert Giasolli

Patent number: 9848882Abstract: An embodiment is directed to an embolic device comprised of a coil made of a first material and disposed on the inside of a tube structure made of a second material. The tube structure has micro-fabricated fenestrations formed in the tube to provide fluid communication between the lumen of the tube and the surrounding environment, thereby exposing the inner coil. The fenestrations also trip flow around the embolic device. In one embodiment, the embolic device is comprised of a tantalum coil on the inside of a polyetheretherketone (PEEK) tube. The PEEK tube has the advantage of providing a micro-machined delivery implant frame and radiopacity, while the internal tantalum coil provides radiopacity and thrombogenicity. A material other than PEEK may be used for embodiments of embolic devices without departing from the spirit of the disclosure.Type: GrantFiled: March 6, 2014Date of Patent: December 26, 2017Assignee: Scientia Vascular, LLCInventor: John Lippert
