GORE® Medical Membranes for Venting, Filtration and Protection in Medical Devices

Gore has been developing high performance expanded polytetrafluoroethylene (ePTFE) membranes to solve the venting, filtration and protection challenges faced by medical device designers and manufacturers for over 25 years.

Venting

GORE® Medical Membranes Venting Products are designed for high levels of gas permeability which can allow for fast pressure equalization and airflow. Some medical liquids can contain entrained gas which may present a hazard to the patient or affect the proper operation of a medical device. GORE® Medical Membranes can aid the dissipation of these gas bubbles while retaining liquids that are under pressure.

Filtration

GORE® Medical Membranes Filtration Products meet the challenges of filtering gases and liquids. Due to the microporous structure of Gore's ePTFE membranes, fluids can pass through the membrane with low pressure drop, while removing contaminants.

Protection

GORE® Medical Membranes protect sensitive acoustic components from liquids and particles while maintaining their sound integrity. In hearing instruments for example the GORE membrane performs as a barrier against water and contaminants while at the same time preserving its overall sound quality. In personal hygiene devices like electric toothbrushes the ePTFE membrane not only equalizes pressure differentials caused by rapid temperature changes, but also offers protection against water and particle intrusion while allowing the battery to safely outgas.


Common applications for GORE® Medical Membranes include:

  • Hearing Instruments
