Patent Issued for Kerstpiek Tip for Medical Devices

June 16, 2014

By a News Reporter-Staff News Editor at Biotech Business Week -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Weber, Jan (Maastricht, NL); Anderson, James M. (Fridley, MN); Chang, Robert (Belmont, CA), filed on January 30, 2013, was published online on June 3, 2014 (see also Biotechnology Companies).

The assignee for this patent, patent number 8740842, is Boston Scientific Scimed, Inc. (Maple Grove, MN).

Reporters obtained the following quote from the background information supplied by the inventors: "Percutaneous medical devices may vary across a broad range of sizes, from the very small (in length, cross-section, or sheer bulk) to the very large. As the size of a medical device increases, the risk or potential for navigational difficulty through the vasculature and/or abrasion or injury to the walls of the vessel(s) through which the medical device travels also increases. For example, a large medical device, such as some used in certain angioplasty, atherectomy, stent-deployment, transcatheter aortic valve implantation (TAVI), valvectomy, valvuloplasty, or other intravascular procedures, may be difficult to navigate through tortuous vasculature. Similarly, such large medical devices may also present increased risk of abrasion to the vessel walls as they navigate turns or narrowing lumens. A continuing need exists for improved percutaneous medical devices and methods."

In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors' summary information for this patent: "An apparatus may comprise a medical device including an elongate shaft disposed about a guidewire, and a distal tip including a plurality of rounded protrusions, wherein adjacent protrusions are fixed directly to each other by a discrete, relatively flexible connector. The plurality of protrusions may each decrease in size from a proximalmost protrusion distally to distalmost protrusion.

"Although discussed with specific reference to use within the coronary vasculature of a patient, for example a tortuous aorta, medical devices and methods of use in accordance with the disclosure can be adapted and configured for use in other parts of the anatomy, such as the digestive system, the respiratory system, or other parts of the anatomy of a patient."
