Patent number: 11617861Abstract: A catheter with three distinct compression resistance coils, including a body coil and two pull wire coils, is disclosed. The triple coil system can provide maximal resistance to compression of the catheter's proximal shaft, as well as maximization of the curve angle that the catheter tip can achieve. Additionally, the tri-coil catheter can allow for a lower initial compression load and a more flexible proximal shaft. A gap between the outer diameter of the pull wire and the inner diameter of the pull wire compression coil that is equal to about 10-30% of inner diameter of the pull wire compression coil can provide optimal catheter performance.Type: GrantFiled: November 23, 2020Date of Patent: April 4, 2023Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Sameer D. Pai, Zachary L. Helgeson, Troy T. Tegg

Patent number: 11064929Abstract: The instant disclosure relates generally to a tip electrode for delivering irrigant to a distal portion of the tip electrode and irrigated catheter tips incorporating such a tip electrode. The distal portion of the tip electrode can have additional fluid ports on the distal edge of the tip to provide additional fluid flow to that region.Type: GrantFiled: December 15, 2015Date of Patent: July 20, 2021Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Sameer D. Pai, Andrew R. Oliverius, Troy T. Tegg
