An implantable medical device includes an energy storage device with an internal component and an outer case that encloses the internal component. The outer case is electrically connected to the internal component. The energy storage device includes a first electrode that is electrically connected to the internal component. Furthermore, the device includes a control assembly with a control component and a control case that encloses the control component. The control case is coupled to and electrically connected to the outer case. The control component is electrically coupled to the first electrode and the outer case to be powered by the internal component of the energy storage device. The control component controls transmission of an electrical signal between the implantable medical device and biological tissue. Also, an outer surface of the outer case and the outer surface of the control case are exposed to the biological material.

A capacitor-discharge implantable cardioverter defibrillator (ICD) has a relatively smaller energy storage capacity of less than about 1. 0 Amp-hours. The smaller energy storage capacity of the ICD is achieved by selecting and arranging the internal components of the ICD to deliver a maximum defibrillation countershock optimized in terms of a minimum physiologically effective current (I. sub. pe) rather than a minimum defibrillation threshold energy (DFT). As a result of the optimization in terms of a minimum effective current I. sub. pe, there is a significant decrease in the maximum electrical charge energy (E. sub. c) that must be stored by the capacitor of the ICD to less than about 30 Joules, even though a higher safety margin is provided for by the device. Due to this decrease in the maximum E. sub. c, as well as corollary decreases in the effective capacitance value required for the capacitor and the net energy storage required of the battery, the overall displacement volume of the ICD is reduced to the point where subcutaneous implantation of the device in the pectoral region of human patients is practical.

An improved connector for interconnecting a furcated lead and signal generator to form a body implantable stimulator. The connector is secured to the signal generator to form a signal generator assembly. Jacks are provided in the connector to receive the lead furculae while facilitating conformance of furculae to the configuration of the signal generator assembly on wrapping of the furculae around the signal generator assembly. In a preferred embodiment, the jacks accept the furculae at different distances from the signal generator to allow a thinner signal generator assembly and at different depths to compensate for the difference in distance of the jacks from the signal generator.

Electrical stimulation may be configured to decrease renal sympathetic activity by creating at least a partial functional conduction block in the efferent and/or afferent sympathetic nerve fibers that innervate the kidneys. An electrical stimulator may deliver a stimulation signal to a renal nerve of a patient. The stimulation signal may be a biphasic signal with a frequency of approximately 100 hertz to 20 kilohertz. In some examples, a sensor may sense a physiological parameter of the patient, and the stimulation generator may activate, deactivate, or adjust the stimulation signal based on the physiological parameter. The physiological parameter may be indicative of sympathetic activity within the patient.

A method and apparatus for treating atrial tachyarrhythmias, particularly atrial fibrillation. High energy pulses are delivered between electrodes located in the right atrium/SVC, the left pectoral region and the coronary sinus/great vein, with the left pectoral and coronary sinus/great vein electrodes connected in common. Optionally a ventricular electrode may also be employed in conjunction with one or more of the other listed electrodes to accomplish ventricular cardioversion or defibrillation.

A hermetically sealed pressure transducer suitable for implantation in a human body. A pressure sensitive circuit is fabricated using contemporary silicon technology. The pressure sensitive circuit is sealed in an oil-filled chamber formed within a titanium cylinder having a glass substrate bottom and a thin titanium top. According to one embodiment, the pressure sensitive circuit contains a sealed inner chamber at a known pressure, thereby measuring pressure relative to a known value. A second embodiment vents the pressure sensitive circuit to produce a relative pressure measurement. A grill protects the assembly and aids insertion into the desired area. A lead connects the transducer to an implantable sensing circuit.

An implantable medical device is configured so that all of the major components including a housing and attached leads are disposed within the vasculature of a patient. A tether extends from the housing of the device to an implant location where the tether is secured to tissue outside of the vasculature. In this manner, an intravascular medical device may be implanted at a location remote from final placement, delivered via the vasculature and anchored at the initial entry point.
