Abstract: Methods and kits for subcutaneous defibrillator implantation. In various examples, two introducer tools each having a sheath are used during an implantation procedure to obviate the need for pulling a lead using a suture. The elimination of the suture-based pulling steps may reduce procedure time. A kit having two introducer tool and corresponding sheaths is also disclosed.

Abstract: A catheter for delivering a medical electrical lead to a bundle of His from within a right atrium of a heart. The catheter includes a straight portion and a hook portion projecting from a distal end of the straight portion. The hook portion includes a first curved portion, a second curved portion, and a third curved portion. The straight portion and the first curved portion define a plane. The second curved portion extends from a distal end of the first curved portion. The second curved portion curves away from the plane. The third curved portion extends from a distal end of the second curved portion. The third curved portion curves toward the plane. The catheter forms a lumen extending from a proximal end of the straight portion to an opening at a distal end of the third curved portion.

Abstract: IMD devices and implantation methods are discussed and disclosed. Electrode structures may be employed to allow electrical stimulation to heart tissue and/or sense a physiological condition. Devices may be used for the placement of the electrode structures in a patient and facilitate the degree of contact between the electrode structures and the tissue of the patient.

Abstract: Implantation of a cardiac stimulus system using the intercostal veins. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed by entering the brachiocephalic vein from a jugular, subclavian, or other vein, and then accessing the internal thoracic vein, traversing a portion of the internal thoracic vein and then accessing an intercostal vein therefrom. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein, advancing superiorly into the internal thoracic vein and then accessing an intercostal vein therefrom. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance to enter the intercostal vein directly.

Abstract: Cardiac therapy devices in the form of pacemakers and/or defibrillators including one or more leads with electrodes implanted in a vein in a posterior position in combination with one or more leads with electrodes implanted in an anterior position. The posterior position may be chosen from one or more of the azygos, hemiazygos, accessory hemiazygos, or posterior intercostal veins. The anterior position may be chosen from the internal thoracic vein, an anterior intercostal vein, or an anterior subcutaneous location. In other examples, sensors are placed for use by a cardiac monitoring or therapy system in one or more of the internal thoracic vein, the azygos vein, the hemiazygos vein, the accessory hemiazygos vein, and/or an anterior or posterior intercostal vein.

Abstract: A medical device lead includes a tubular conductive element disposed over a lead body. The tubular conductive element includes at least one segment having one or more kerfs formed radially therethrough in a predetermined configuration so as to affect at least one electrical property, e.g., electrical impedance, of the segment. The segment may form a shocking conductor of the medical device lead. The tubular conductive element may alternatively include proximal, intermediate and distal segments each having one or more kerfs formed radially therethrough, where the one or more kerfs in each of the proximal and intermediate segments are configured so that these segments each have a higher electrical impedance than the distal segment. A layer of insulative material is disposed over the proximal and intermediate segments, so that the proximal and intermediate segments of the tubular conductive element are operable to filter electromagnetic energy from an external source.

Abstract: A tool for implanting a medical lead includes a body having distal region including a distal end, a proximal region including a proximal end, a central axis extending from the distal end to the proximal end, and a midpoint between the distal end and the proximal end. The distal region includes a rounded tip, and a distal lip surrounding a distal opening leading to a distal cavity dimensioned to receive and frictionally engage a connector component of the implantable lead. The proximal region includes a proximal lip surrounding a proximal opening leading to a proximal cavity. A chamber is located between the distal cavity and the proximal cavity. The tool includes a first window. A pair of resilient arms define at least a portion of the chamber and configured to frictionally engage a terminal pin of the implantable lead. The first window, chamber, and pair of resilient arms are located distal of the midpoint.
