pressure sensor for catheter application

Pressure Testing Balloon Catheters - Mensor

Medical companies that design and manufacture IAB catheters need to test the pressure sensor, which is a key element of the catheter and in turn the entire IABP system. The pressure sensor usually needs to be tested as part of the complete assembly or tray, which is typically the package used to transit the IABP to the medical facility.

Scisense Pressure Catheters

The spacing between the two pressure sensors on Dual Catheters is adjustable at no additional cost and should be determined based on animal size and application (location of pressure measurements). The first pressure sensor on small Catheters ( - ) is at the tip and slightly proximal to the tip on large Catheters ( - ).

Optical Fibre Pressure Sensors in Medical Applications

Catheter-based pressure systems use a catheter filled with an incompressible medium (, water or saline solution), connected to a pressure sensor . A change in pressure at the tip of the catheter results in a deformation of the diaphragm, which compresses or decompresses the water and, hence, transmits the pressure directly to the connected ...
