Publication number: 20240148305Abstract: A delivery device for delivering a pacing lead to the His bundle of a patient's heart includes an elongated sheath having a distal end, and a plurality of mapping electrodes positioned at the distal end. The distal end of the sheath may have a distal tip, and the mapping electrodes may include two electrodes that diametrically oppose one another at a position spaced from the distal tip of the sheath. The sheath includes a plurality of flexible sections spaced apart from one another, and a pull wire that causes the sheath to deflect from a straight configuration to a dual hinged curved configuration that positions the electrodes in the vicinity of the bundle of His.Type: ApplicationFiled: January 17, 2024Publication date: May 9, 2024Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Scott A. Kramer, Erich W. Stoermer, Joshua C. Conway, Gene A. Bornzin, Zoltan Somogyi, Amy L. Hanenburg, Emily Weiss, Paul A. Belk, Patrick P. Senarith

Publication number: 20220347463Abstract: A delivery device for delivering a pacing lead to the His bundle of a patient's heart includes an elongated sheath having a distal end, and a plurality of mapping electrodes positioned at the distal end. The distal end of the sheath may have a distal end face, and the mapping electrodes may include two electrodes that diametrically oppose one another at a position exposed on or spaced from the distal end face. The sheath includes a plurality of flexible sections spaced apart from one another, and a pull wire that causes the sheath to deflect from a substantially straight configuration to a dual hinged curved configuration that maneuvers and positions the electrodes in the vicinity of the bundle of His. The sheath may include a PTFE liner having axially oriented, platelet-like fibril features that enable the sheath to be split along its length from a proximal end to the distal end.Type: ApplicationFiled: July 5, 2022Publication date: November 3, 2022Inventors: Xiaoping Guo, Erich W. Stoermer

Patent number: 11295634Abstract: An electro-anatomical model of the mammalian His/Purkinje system includes a shell simulating the anatomy of at least a portion of a mammalian heart. The shell has a hollow interior and a first port providing an aperture to the interior of the shell. A plug is inserted in the first port so that a surface of the plug is exposed to the interior of the shell. An electrical circuit provides signals to electrodes in the plug which simulate the electrical signals generated by the bundle of His/Purkinje system in vivo. A second port provides access to the interior of the shell for an introducer catheter to locate the simulated bundle of His and to insert a pacing lead therein. The model is useful for developing tools for His pacing and for training users in techniques for implanting His pacing leads.Type: GrantFiled: December 3, 2018Date of Patent: April 5, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Scott A. Kramer, Paul A. Belk, Juan Carlos Tantalean, II, Gavin P. Seeker, Patrick P. Senarith, Erich W. Stoermer, David J. Broman
