摘要：
A pressure sensor module configured for implant at a desired site at which a pressure is to be measured. The pressure sensor module includes a pressure sensitive membrane which is in direct contact with the environment at which a pressure is to be measured. The pressure sensor module forms a part of a pressure measuring system which uses a telemetry link between the pressure sensor module and an external controller for data transmission and transfer. The pressure measuring system provides a dual stage power and data transfer capability for use with an implantable system. An exemplary use is in a three pressure sensor system including a flow control valve in a shunt to treat hydrocephalus. An embodiment of the invention includes a pressure sensor and associated electromagnetic coils embedded in the tip portion of the shunt for measuring the pressure of fluid externally of the shunt at the tip portion.
