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: 9913961Abstract: The present disclosure provides a strong, flexible catheter shaft for use in a catheter system. The flexible catheter shaft includes a braided polyimide tube including one or more outer layers of material of varying flexibility. 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 into side branches or bifurcations in the vasculature of a patient and includes a distal spring coil.Type: GrantFiled: October 9, 2014Date of Patent: March 13, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Tobias Cajamarca, Gregory James Dakin, Jeffrey John Strong

Publication number: 20150270634Abstract: Embodiments of the present disclosure provide ablation catheter systems and electrode assemblies and electrode baskets for use in the ablation catheter systems that include one or more struts that have a non-uniform thickness along their length to customize the strut performance The struts having a non-uniform thickness in accordance with the present disclosure may be utilized in electrode baskets that include any number of struts in any design formation. Common examples include electrode baskets having two, three, four, five or six or more total struts. Suitable struts having a non-uniform thickness along their length may be comprised of a memory shape alloy, such as Nitinol, from a thermoplastic material, or from a combination thereof. Electrode baskets may include thinned struts of different materials.Type: ApplicationFiled: February 19, 2015Publication date: September 24, 2015Inventors: Ryan Kenneth Buesseler, Gregory James Dakin

Publication number: 20150005704Abstract: A medical device, such as an introducer, includes a shaft having a lumen therethrough. A distal region of the shaft includes both a fixed curve region and a steerable region. According to certain aspects of the disclosure, the fixed curve region is more proximal than the steerable region. The fixed curvature of the distal region is selected to facilitate positioning of the distal end of the medical device in the general vicinity of a target, such as the left atrial appendage, while the steerable region allows for “fine tuning.” The lumen of the shaft is a large bore, typically on the order of about 12F to about 14F, to facilitate passage of larger medical devices, including left atrial appendage occlusion devices.Type: ApplicationFiled: May 7, 2014Publication date: January 1, 2015Applicant: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Jennifer Marie Heisel, Gregory James Dakin, Somally Mom
