Access to the left side of the heart is gained through a heart wall. A delivery instrument includes a guide that may include or carry a puncturing instrument that is adapted to be directed toward the heart wall. In some embodiments a distal portion of the delivery instrument may be adapted to be co-located with the coronary sinus. In addition, the guide may be located a known distance from the portion of the delivery instrument that is co-located with the coronary sinus. Access to the left side of the heart may thus be readily gained by positioning the delivery instrument relative to the coronary sinus.

An implantable medical lead is disclosed herein. The lead includes a first electrode and a first electrical circuit. The first electrode is near a distal portion of the lead. The first electrical circuit extends through the lead to the first electrode and includes at least one conductor and a first band stop filter coupled between the distal end of the conductor and the electrode. The first band stop filter includes a first group of inductors in parallel and a second group of inductors in parallel. The first group is in series with the second group. The first group of inductors may include a self resonant L. The first group of inductors may include a self resonant tank LC. The first group of inductors may include a miniature self resonant L or miniature self resonant tank LC. The first group of inductors may include an integrated circuit of L and C components.

A defibrillator patch lead having a connecting element interconnecting an electrical conductor and a wire mesh electrode pad. The connecting element includes a body portion which has a slot cut therein into which a portion of the wire mesh electrode is inserted and securely bonded, preferably by laser welding. The connecting element further includes a female connector portion which is designed to mate with a male core sleeve. The core sleeve includes a channel for receiving a first conductor therein, which is then electrically and mechanically connected (e. g. , by either welding or crimping). The core sleeve also includes an orifice for receiving a second conductor, which is subsequently electrically and mechanically connected (e. g. , by either welding or crimping) between the core sleeve and the connecting element. Advantageously, the combination of the core sleeve, two conductors, and the connecting element have superior pull strength over conventional methods of attachment.

An electrical conductor assembly utilized, for example, in a defibrillator patch lead to interconnect a pulse generator and monitoring unit, and a wire mesh electrode pad. The electrical conductor includes a Teflon insulated drawn brazed stranded (DBS) wire cable which is wrapped in a drawn filled tube (DFT) wire multifilar coil encased in a biocompatible insulative tubing.
