Mott Corporation Release: Porous Metal Products Used in Medical Device Designs

Published: Mar 12, 2013

FARMINGTON, CT (March 2013) – Mott porous metal products are playing an increasing role in medical device designs and applications.

Porous metal has been widely used in advanced technology applications and has found a number of uses in the design and manufacture of medical devices. Porous metal is ideal for providing highly dependable filtration performance, controlling fluid flow, as well as diffusion and metering of fluids and drugs. Rigid and robust, porous metal affords designers novel and unique properties that are often the solution for challenging medical and life sciences applications.

Porous metal is available in biocompatible materials commonly relied on by the medical industry including stainless steel and titanium. Mott Corporation supplies components in 316L, 304, 310 and 400 series stainless steels, unalloyed titanium (ASTM 1580-07), as well as a number of other common and exotic metallurgies including zirconium, molybdenum, niobium, and precious metals including gold, silver, palladium and others.

Mott Corporation offers an all-metal membrane that meets ASTM F838-05 for bacterial retention. Mott sterilizing grade membranes are supplied in 316L stainless steel or titanium. This technology is available in a variety of form factors from very small discs or tubes for drug delivery applications to larger 10” cartridges for biotechnology and pharmaceutical processing. This proprietary membrane is able to withstand aggressive chemistries and drug cocktails without the potential for leaching, outgassing, or other adverse reactions. Mott porous metal components are available with filtration ratings from sub-micron (0.1µm) to coarser filtration ratings, including 0.2 µm sterilizing grade media. Mott also produces specialized gas filters that can achieve 99.9999999% efficiency for particles as small as .003 µm.

Porous metal flow restrictors have been used for decades to precisely meter the flow of critical gases in medical and non-medical applications. Mott Corporation has sophisticated modeling and calibration capability that enables us to calibrate the flow of a gas to accuracies of +/-2% at a given inlet and outlet condition. Porous metal can also be designed to permit the controlled diffusion of liquids or gases desirable for certain drug delivery and fluid metering applications.

Mott has a specialized team of experts who work specifically with medical device designers, engineers, and manufacturers on projects that pave the way to tomorrow’s technologies.

Established in 1959, Mott Corporation has long been dedicated to applying sintered porous metal to gas and liquid filtration and flow product concepts. Mott products are used by customers in the medical device, medical instrumentation, pharmaceutical, biotechnology, semiconductor, analytical instrumentation, aerospace, and chromatography industries just to name a few.
