Publication number: 20240009453Abstract: A lead distal tip for a pacemaker includes a lead body including an insulated wire having a diameter of 2 French or less. The small size and flexibility of the lead distal tip and lead body reduce penetration and dislodgement risk for the lead distal tip. The lead distal tip can be delivered using a delivery catheter engaging with features on the lead distal tip to allow for the guidance and securement of the lead distal tip, despite its small and flexible nature. The attachment of the lead distal tip to heart tissue can be achieved by extending a linear member and/or a helical member from an end of the lead distal tip using features provided on the delivery catheter.Type: ApplicationFiled: July 6, 2022Publication date: January 11, 2024Inventors: Yongxing Zhang, Martin Tze, Scott Hayden, Ryan Bauer, Entao Liu
