Patent number: 5304114Abstract: 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.Type: GrantFiled: May 15, 1991Date of Patent: April 19, 1994Inventors: Eric R. Cosman, Michael A. Arnold
