Publication number: 20240041408Abstract: An electrode support structure assembly in a body in accordance with one embodiment of the present teachings includes a plug defining a longitudinal axis. The plug includes a lumen extending in an axial direction and including an axial distal end and a distal tip adjacent to the axial distal end of the lumen and including a first channel. The assembly further includes a cap disposed around at least a portion of the plug and including a plurality of apertures and an interior. The assembly further includes a plurality of support members, each support member comprising a distal portion. The cap is configured to constrain relative movement of the distal portions of the plurality of support members with respect to the cap, and the first channel of the plug and at least one of the plurality of support members are configured to direct a fluid after exiting the lumen of the plug.Type: ApplicationFiled: October 17, 2023Publication date: February 8, 2024Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: James C. Marrs, Neil D. Hawkinson, Brian M. Monahan, Dale E. Just

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
