US 2019/0336747 A1 · SINGLE-SITE IMPLANTATION METHODS FOR MEDICAL DEVICES HAVING MULTIPLE LEADS

Abstract

Methods and devices include making an incision at a single site of a patient. The single site located at an anterior of a chest or abdomen. The method also includes inserting a tunneling tool through the incision at the single site and preparing a first tunnel to a subcutaneous posterior location. A path of the first tunnel at least one of i) extends over a plurality of Intercostal gaps of the chest or ii) extends along and within one of the intercostal gaps. The method also includes positioning a first lead having an electrode within the first tunnel and preparing a second tunnel to a subcutaneous parasternal location along the chest. The method also includes positioning a second lead having an electrode within the second tunnel and positioning a pulse generator within a subcutaneous pocket and operatively coupling the first and second leads to the pulse generator.

A method comprising:

making an incision at a single site of a patient, the single site located at an anterior of a chest of the patient;
inserting a first tunneling tool through the incision at the single site, the first tunneling tool having an elongated shaft and a removable sheath that surrounds the elongated shaft;
displacing underlying tissue with the first tunneling tool along a designated path to prepare a first tunnel, the first tunnel extending from the single site, over a plurality of intercostal gaps of the chest, and within one of intercostal gaps to a subcutaneous posterior location;
withdrawing the elongated shaft, the removable sheath maintaining the first tunnel;
positioning a first lead having an electrode within the first tunnel;
withdrawing the removable sheath;
inserting a second tunneling tool through the incision at the single site, the second tunneling tool having an elongated shaft and a removable sheath that surrounds the elongated shaft of the second tunneling tool;
displacing underlying tissue with the second tunneling tool along a designated path to prepare a second tunnel, the second tunnel extending from the single site to a subcutaneous parasternal location;
withdrawing the elongated shaft of the second tunneling tool, the removable sheath of the second tunneling tool maintaining the second tunnel;
positioning a second lead having an electrode within the second tunnel;
withdrawing the removable sheath of the second tunneling tool;
forming a subcutaneous pre-pectoral pocket;
and
positioning a pulse generator within the subcutaneous pre-pectoral pocket and operatively coupling the first and second leads to the pulse generator.
