Porous metal products, assemblies and filters by Mott Corporation, Farmington, CT, are used in a number of medical applications (gas and liquid) requiring exacting filtration performance, precise flow specifications, biocompatibility, high-temperature resistance, and the ability to withstand aggressive thermal and chemical sterilization processes repeatedly. The company designs and manufactures porous metal products to specifically meet filtration and flow-control requirements for many medical device manufacturers and designers.  These products include biocompatible porous titanium filters, implantable devices for venting or drug delivery, metal filters for test stands, spargers used in cell-culture processes, filters to prevent plugging in catheters, and precision flow restrictors for the delivery of gases in life-critical systems. Benefits of the porous metal products include strength-to-weight ratios; reliable filtration media to prevent particle bypass or contamination; uniform controlled porosity of the material which allows precise flow rates at specified pressures; and a variety of available alloys ensuring biocompatibility, bio and chemical inertness, and stable thermal performance. Porous metal is also used for filtration of carrier gases and cryogenic fluids in medical devices and laboratory settings, vents for bioreactor and fermentor vessels, lubrication for surgical devices, as well as for radiological processes and other unique applications.
