Abstract
The present invention relates to a pressure sensor module for use in catheters having a pressure sensor operable to provide a signal representative of pressure. The pressure sensor includes a sensing side and a pressure reference side. At least one signal transmission media is coupled to the sensor for transmitting the signal representative of pressure. A convex-shaped carrier is provided having a slot formed to expose the sensing side of the sensor. The convex-shaped carrier is adapted for receiving the sensor such that the sensing side of the sensor is adjacent the slot. A bonding material is provided for mounting the sensor to the carrier. The pressure sensing module provides ease of installation and manufacture because the module may easily be bonded to and installed within a catheter.
