Assignee: PACESETTER, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A subcutaneous implantable medical device (SIMD), comprising:
a pulse generator (PG) configured to be positioned subcutaneously within a lateral region of a chest of a patient, the PG having a housing that includes a PG electrode, the PG having an electronics module; and
an elongated lead that is electrically coupled to the pulse generator, the elongated lead including:
a first electrode that is configured to be positioned subcutaneously proximate to a lower end of a sternum of the patient,
a second electrode that is configured to be positioned subcutaneously along a first parasternal region proximate the sternum,

the first electrode configured to be oriented to extend in a non-parallel direction relative to a direction of the second electrode, the first electrode located at a position, relative to a midline of the sternum, that is vertically below the second electrode; and
an intermediate segment interconnecting a distal end of the first electrode and a proximal end of the second electrode,

wherein the first and second electrodes are coupled to be electrically common with one another,
wherein the electronics module is configured to provide electrical shocks for antiarrhythmic therapy along a shocking vector extending between the first and second electrodes and the PG,
wherein at least one of the first and second electrodes has an active length that is 7-11 cm to define an impedance along the shock vector between the first and second electrodes and the PG to be no more than 64 ohms.
