Abstract
A body fluid pressure sensor module according to the invention comprises a housing having a first end and a second end and enclosing a pressure sensor. The pressure sensor is electrically coupled to a plurality of electrical conductors extending into the housing through a feedthrough disposed within, and hermetically sealing, the first end of the housing. The housing defines a chamber disposed between the feedthrough and the second end of the housing. The chamber contains a material in communication with the pressure sensor, the material being capable of transmitting pressure variations to the pressure sensor. The plurality of electrical conductors have ends within the housing, and the pressure sensor is mounted on the end of at least one of the conductors. Also disclosed are medical leads incorporating the pressure sensor module, and methods for fabricating the modules. The pressure sensor module is compact, and particularly so where cable conductors are utilized and the sensor is directly mounted on at least one of the cable conductors. The compactness of a pressure sensor module pursuant to the invention facilitates its incorporation into a small diameter, flexible medical lead …
