An electrical brain contact device and device for connecting a plurality of lead wires with individual take-up terminals is described. The lead wires in the brain contact device extend to a terminal mount with an array of lead-wire terminals on it. A connector assembly includes a connector block with a matching array of take-up terminals and an elongate cavity to receive the terminal mount, and a mechanism to removably draw the take-up terminals into terminal-to-terminal contact with the terminal mount to facilitate electrical connection.

Connector design for multi-contact medical electrode

This invention relates to a CSF shunting system that can be used in the human body for the control of hydrocephalus or excess cerebrospinal fluid (CSF) in the ventricles of the brain. The invention relates to the configuration of a fluid pressure controlling diaphragm which has a substantially planar, non-arched, or slightly convex occluding surface that contacts as its valve mechanism a non-planar opposing surface. The diaphragm element can be made out of silicone rubber or some other flexible material, and the opposing surface can be made from a dissimilar material from the diaphragm element to prevent sticking. The invention also relates to the configuration of this substantially flat diaphragm element, its central stem, and its mounting in a frame so as to facilitate pre-loads, calibrations, and optical, as well as mechanical, tests for quality assurance. The invention further relates to a confirmation of this pressure control invention in a larger shunt body geometry, which provides for modular, distal, and occlusion elements, and articulating shape to better fit the contour of a patient's skull.
