General PurposeCatheter Tip Pressure Transducers

Robust metal sensing diaphragms within polished surgical steel bodies

Excellent frequency response and very simple to use.

The Gaeltec Devices CTC range feature robust metal sensing diaphragms within polished stainless steel (AISI type 304) bodies which can be mounted on a variety of catheter types. They have excellent frequency response and are simple to use.

The units are 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 always try to provide the exact requirements of our customers and can usually combine elements from any of our catheter designs into one unit in a modular fashion. Over the years we have made a wide variety of devices using our proven technology.
