Publication number: 20230301714Abstract: An elongate medical device shaft may comprise an elongate body and an annular electrode disposed on the elongate body. The annular electrode may define a longitudinal axis and have an outer diameter. The outer diameter may be greater at an axial center of the electrode than at an axial end of the electrode. Additionally or alternatively, the elongate body may comprise three longitudinal sections having three wall thicknesses. The middle wall thickness may be less than the proximal and distal wall thicknesses and the distal wall thickness may be less than the proximal wall thickness. Additionally or alternatively, the shaft may comprise an inner cylindrical structure and an outer tube. The outer tube may comprise a first radial layer and a second radial layer that is radially-outward of the first radial layer, the first radial layer, second radial layer, and inner structure having different stiffnesses.Type: ApplicationFiled: May 16, 2023Publication date: September 28, 2023Inventors: Zachary L. Helgeson, Alexander C. Houck, John Her, Salo Arias, Somally Mom, Brian M. Monahan, Neil D. Hawkinson, James R. Nigg, James C. Marrs, Xuan Yen Khieu, Troy T. Tegg, Jill A. LaFavor, Israel A. Byrd

Publication number: 20230210432Abstract: A partially-masked electrode includes a conductive material and an insulated coating having an outer surface. The insulated coating defines a contoured opening that exposes or reveals an area of the conductive material, wherein the contoured opening has an upper perimeter at the outer surface of the insulated coating. When the upper perimeter of the insulated surface coating is placed in contact with a tissue of interest, wherein the tissue of interest is proximate a blood pool, the insulated coating creates a seal between the blood pool and the contoured opening so that no blood in the blood pool can contact the conductive material. This seal reduces or eliminates the reception of far field effects in the blood pool by the electrode, making it easier to locate and diagnose unhealthy tissue.Type: ApplicationFiled: December 27, 2022Publication date: July 6, 2023Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Gregory K. Olson, Travis Dahlen, Brian M. Monahan, Loell B. Moon
