Patent ID: 7418868

Claim:
A body fluid pressure sensor module comprising: a housing having a first end and a second end; a pressure sensor within said housing, the pressure sensor being electrically coupled to a plurality of electrical conductors extending into said housing through a feedthrough disposed within, and hermetically sealing, said first end of said housing, said housing defining a chamber between said feedthrough and said second end of the housing; and a biocompatible gel or fluid within said chamber in communication with said pressure sensor, the biocompatible gel or fluid being capable of transmitting pressure to said pressure sensor; wherein the housing has a side wall having an aperture therethrough, and wherein the pressure is transmittable by said biocompatible gel or fluid in a direction transverse to a longitudinal direction extending between said first and second ends of the housing; wherein said pressure sensor has a diaphragm disposed at the aperture; wherein said second end of said housing comprises a deflectable membrane, and wherein the biocompatible gel or fluid transmits axially directed pressure from the deflectable member to the diaphragm; and wherein the deflectable membrane is disposed at a distal tip of a lead.
