DYMAX (Torrington, CT) offers DYMAX MD® 1200 series adhesives for rapid bonding of a variety of substrates found in medical devices. These adhesives are bright blue in their uncured state, making them easy to see on a variety of substrates, in deep wells, or when sandwiched between two layers of materials. The blue color allows automated vision systems to confirm adhesive placement prior to curing, for greater efficiency and less scrap. During the light-curing process, the blue color transitions to clear to indicate that the full cure has been achieved. The visual cure-indicator may be used to qualify the process and to ensure that the process remains within established control parameters. It is solvent-free and cures in seconds when exposed to high-intensity UV/visible light. It is compatible with gamma, EtO, and e-beam sterilization.

Sensortechnics (Walpole, MA) offers the Ten-X Series of 2-way and 3-way solenoid valves available with integrated "Hit and Hold" drive electronics to reduce power consumption and heat generation using pulse width modulation. The valves offer high flow rates of 8 lpm at 6 psi and 22 lpm a t30 psi through a 0.060" orifice. The compact 10-mm-wide package offers barbed pressure ports for direct tubing connections, or manifold mount assemblies using the Ten-X gasket. They are suitable for portable, medical, and analytical device applications.

TDK-Lambda (San Diego, CA) has introduced the NVM175 series of medically approved AC-DC power supplies. Combining 4.5 kVac reinforced input to output isolation with dual input fusing and an output-to-ground isolation of 1500 Vac, the NVM175 meets UL/EN/IEC60601-1 and is suitable for use in BF (Body Floating) type medical applications (e.g. ultrasound, ECG, patient monitors, etc.) It offers a compact 5" × 3" footprint with less than 1U height (1.02" high component height), and universal AC input. It is rated at 180 W at 50 °C with user supplied air flow. Leakage current is 80 μA maximum with 120 Vac/60Hz input. Available with either 12 or 24 V output voltage (with 12V/0.2A standby), the NVM175 achieves up to 90% efficiency, less than 1 W standby power, and RoHs and REACH compliance. Standard features include a power good signal, remote on/off, remote sense, and protection from over-current, over-voltage, and over-temperature conditions.

Colder Products Company (St. Paul, MN) offers AseptiQuik™ connectors with a "click, pull, twist" design: an audible click confirms the initial connection, pull tabs allow simultaneous membrane removal, and a twist of the integrated lock ring provides secure final assembly. Connection can be made without the need for additional clamps, fixtures, or tube welders. Validation testing has confirmed that the connectors enable sterile media transfer, even in non-sterile environments.

Medical device design presents specific challenges for finite element analysis (FEA) engineers, who are tasked with simulating the mechanical behavior of medical devices or their components under a variety of conditions. These simulations help designers optimize the device and/or its component design prior to prototyping and physical testing.

ITT Interconnect Solutions (Santa Ana, CA) offers the Nemesis Series and MKJ Series breakaway connectors that incorporate a simple push/pull mating mechanism to engage and disengage the connector systems. The coupling mechanism utilizes a canted spring design, which allows for quick disconnect and ratings of more than 5,000 cycles. The system allows the connector receptacle to house individual touch pad contact areas, providing a highly effective electrical engagement point of contact. The Nemesis Series sealed, lightweight, miniature connectors are resistant to salt spray for more than 500 hours, measure less than 15mm in diameter, and have an anti-reflecting coat. Maximum current rating for the Nemesis WT connectors is 3A and voltage rating is 200VAC RMS at sea level. Minimum insulation resistance is 5000 MΩ, and maximum contact resistance is 8 mΩ. Operating temperature ranges from -40 °C to 100 °C. Life span is 2,500 cycles. The MKJ Series miniature, circular connectors are available with mounting options for crimp and PC board contacts. They feature size 23 pin-and-socket contacts that have the equivalent electrical performance of size 22 contacts. Dielectric withstanding voltage at sea level is 500VAC RMS, 60Hz. Operating temperature ranges from -55 °C to 150 °C.

Minnesota Rubber & Plastics (Minneapolis, MN) offers F-treated FKM elastomers for custom-designed seals located in medical devices such as endoscopes. The F-treat process provides a low coefficient of friction surface that will not dissipate with wear. The treatment provides surgeons with more sensitivity and “feel” for their instruments than non-treated elastomer seals. Unlike topical modifications, F-treat is a modification of the entire compound so that even if abrasion or wear occurs, a modified low friction surface will always be present.
