Lower GICatheter Tip Pressure Transducers

Robust metal sensing diaphragms mounted within soft flexible silicone rubber catheters

Excellent frequency response and are simple to use for standard manometry as well as ambulatory recording.

Compatible with a wide range of monitors, which have been set for use with conventional transducers having a sensitivity of 5µV/V/mmHg.

Sterilisation is by means of cold aqueous solutions of detergicide (e.g. Cidex) or by ethylene oxide gas. Do not use sodium hypochlorite solution.

We can make special units with other configurations of lumen and balloon tie in this range of extra long catheters.
