TOP PRODUCTS & SERVICES
A giant magnetoresistive (GMR) magnetic sensor is designed for use in battery-powered implantable devices such as pacemakers, ICDs, neurostimulators, and drug pumps. Packaged in a four-pin 1.1 × 1.1 × 0.45-mm ultra leadframe land-grid-array leadless package, the BD020 is suitable for wire-bonding assembly. The integrated circuit consists of a GMR sensor element, CMOS signal processing circuitry to convert the analog sensor element output into a digital output, and oscillator and timing circuitry for power-management duty cycling. Configured as a magnetic switch, the sensor produces an output that turns on when a magnetic field is applied and turns off when the field is removed. In addition, the sensors have an integrated latch ensuring that the output is available continuously. The minimum magnetic operate point is 10 Oe. The applied magnetic field can be of either polarity, and the magnetic operate point is stable over supply voltage and temperature. Smaller than reed sensors, these sensors can also provide more magnetic sensitivity and more-precise operate points.

Miniature surface-mount-technology housings allow for space-saving PCB mounting and OEM design flexibility. An internal application-specific integrated circuit compensates for sensor offset, temperature effects, and nonlinearity, enabling a total error band better than ±0.5% frequency selective surface. The pressure sensors provide digital interfaces using the I²C bus protocol and analog 0.5-4.5-V output signals.
Sensortechnics, Walpole, MA
A contract manufacturer specializes in extrusion molding of components for sterile disposable medical devices such as infusion sets, easy-to-fill disposable elastomeric infusion pumps, and accessories used for antibiotics, chemotherapy, and pain management. The company's infusion kits are latex- and DEHP-free, CE marked, and manufactured in compliance with QSR and ISO 13485:2003 standards. Its pumps are available in soft- and hard-case versions with fill volumes ranging from 50 to 500 ml, infusion rates from 1 to 500 ml/hr, and accuracies to ±10%. In addition to manufacturing services performed in FDA-registered facilities, the supplier offers a range of extrusion consulting services, including quality and regulatory expertise, process validation, and project management. It also assembles and packages extruded products.

Fiber-Optic Pressure Sensor
Based on miniature optomechanical systems (MOMS) technology, a fiber-optic pressure sensor exhibits better thermal performance and stability than previous-generation models, according to its manufacturer. Demonstrating better thermal performance and greater stability than previous sensor generations, the FOP-M260 uses white-light Fabry-Perot interferometry technology, ensuring accurate and reliable measurements under all field conditions. With a diameter of 260 µm, the sensor is smaller than a 1 French catheter and half the size of the company's FOP-MIV pressure sensor.

Miniature Ball Valves
A series of miniature ball valves is designed for applications requiring pressure up to 250 psig. It includes the MBV-1010 standard shutoff valve, the MBVT-1010 three-way diverting valve, and the MBVMD-1010 three-way mixing diverting valve. Compact and lightweight, the valves offer nonrestricted flow and are available with a variety of seals. The standard shutoff valve weighs approximately 9 g; the other two valves each weigh approximately 12 g. The valve bodies are available in either Type 303 or Type 316 stainless steel. All of the valves use Type 316 ball elements. Suited for use in a variety of prototype and device designs, the valves can also be used for a range of medical equipment.

Custom Converting Capabilities
Providing specialty materials, engineering, and manufacturing services, a supplier makes IV-site and wound-care products as well as medical devices and disposables. Using a fully equipped Class 10,000 cleanroom, the company converts materials such as electrical-grade papers, films, coated cloths, laminates, and tapes. Its manufacturing capabilities range from die-cutting and slitting to more-complex laser and water-jet cutting to produce intricate patterns and parts. With access to a range of materials, the company custom-converts diagnostic test strips and carrier frames, composite wound-care dressings, die-cut medical-grade foam tape, and woven and nonwoven biocompatible pressure-sensitive adhesive tapes. In addition, the company provides printing services for tamper-evident and custom pressure-sensitive labels used on various medical products.
