摘要:
A battery assembly for a medical device, the battery assembly comprising a cathode (238) consisting of a single, solid, cylindrical elongate cathode comprising carbon monofluoride and silver vanadium oxide, the cathode having first and second ends; a current collector within the cathode; an anode (236) consisting of a single, tubular-shaped lithium metal anode; a separator (240) consisting of a single, tubular-shaped separator disposed between the anode and the cathode and having a closed end covering the second end of the cathode, the cathode, anode and separator being coaxial; an electrolyte; a cylindrical housing assembly electrically coupled to the anode and encapsulating the cathode, the anode, the separator and the electrolyte; and a feedthrough pin (260) exposed from and electrically insulated from the housing assembly, the cathode being electrically coupled to the feedthrough pin through the current collector within the cathode.
摘要:
A battery assembly for a medical device includes an elongate cathode, an elongate anode, an electrolyte, and an elongate housing assembly encapsulating the cathode, the anode, and the electrolyte. The battery assembly also includes a first electrode exposed from and electrically insulated from the housing assembly. One of the anode and the cathode is electrically coupled to the first electrode, and the other of the anode and the cathode is electrically coupled to the housing assembly. Respective axes of the cathode and the anode are substantially parallel to an axis of the housing assembly, and the cathode and anode each include a flat portion that face each other.
摘要:
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.
