Patent number: 10034705Abstract: The present disclosure is directed to electrode assemblies, and specifically to struts comprising electrode assemblies and electrodes contained on the struts. The electrode assembly struts are constructed to have a low profile and to have superior strength over the length of the strut such that an electrode assembly including the strut is highly resistant to radial compression. The electrodes included on the low profile, high strength strut also is designed to have a reduced profile such that electrode assemblies including the strut and electrode can easily be used with 6 French and smaller guide catheter assemblies.Type: GrantFiled: October 23, 2014Date of Patent: July 31, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: John Jason Buysman, Ryan Kenneth Buesseler, Qingshan Ye, Victor Yevgenyevich Kotov, Gregory James Dakin, Russ Terwey, Janson Lee Ayer

Patent number: 9999748Abstract: The present disclosure provides a strong, flexible catheter shaft for use in a catheter system. The flexible catheter shaft includes a nitinol tube having one or more sets of cuts therein in combination with one or more outer jacket layers. The flexible catheter shaft provides a shaft having sufficient stiffness and kink resistance to allow an operator to advance an electrode basket connected to the flexible catheter shaft through a guide catheter to a target ablation site without causing vessel trauma. The distal tip of the flexible catheter shaft is designed to have sufficient flexibility to reduce any risk of kicking out a guide catheter when tracking the electrode basket around turns in the vasculature of a patient.Type: GrantFiled: October 8, 2014Date of Patent: June 19, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Tobias Cajamarca, Jeffrey John Strong, Russell D.
