摘要： The electrode array is a device for making multiple electrical contacts with cellular tissue or organs. The electrode array includes a base (1), a two dimensional array of conducting protuberances (2) arising from the base and serving as electrodes, and conductors (3) embedded onto the base and connected to such protuberances for transmitting electrical signals to and/or from the protuberances. The protuberances may also include an insulating layer (15) which covers either the entire protuberance or which leaves the tips exposed for making focused electrical contact. Electrode arrays may be used singly or in combination with a second electrode array so as to form a sandwich around a target tissue. The sandwich electrode array (16, 17) may employ indexing cones for aligning the opposing electrode arrays and for limiting their vertical proximity. The conductors of the electrode array may be electronically connected or coupled to processing circuitry which amplifies and analyzes the signal received from the tissue and/or which generates signals which are sent to the target tissue and possibly coordinates the generated signals with signals which originate with the tissue.

摘要： The invention discloses methods of making electrical connections in living tissue between an electrically conductive wire and an implantable miniature device. The device may either stimulate muscles or nerves in the body or detect signals and transmit these signals outside the body or transmit the signals for use at another location within the body. The device is comprised of an electrically insulating or electrically conductive case with at least one electrode for transmitting electrical signals. The electrodes and the wire-electrode connections are protected from the aggressive environment within the body to avoid corrosion of the electrode and to avoid damage to the living tissue surrounding the device.
