Laser System Makes Mark in Medical Applications

A new laser marking system that requires no special additives and is suitable for medical applications was featured at a recent manufacturing show in the Netherlands.

Traditional laser marking techniques rely on infrared light, which burns special additives in a substrate to make them visible. In contrast, the new system from Coherent Laser Group (Santa Clara, CA) uses a 355-nm UV laser and introduces no physical degradation to the surface being marked. Instead, the technique employed by the company relies on the laser-induced reduction of titanium dioxide (TiO2) molecules in the material to be marked. TiO2 is a readily available reagent and is commonly used to whiten plastics.

A further advantage of Coherent's system is that it is polymer independent. The technology can be used to mark on a variety of materials including polypropylene, polyethylene, polyvinyl chloride, ABS, and polymer blends. Marco Bak, managing director of Coherent's Netherlands-based subsidiary Lasertec B.V., says that this feature is often attractive to device OEMs that do not want to commit themselves to more-expensive laser-grade plastics often required in infrared marking.

The company recently supplied a turnkey laser marking system employing this technology to Siemens Medical Instruments in Singapore for the marking of delicate hearing aid components. According to Bak, the Siemens project presented a logistical challenge typical of the medical industry. "The problem was that they were using printing, which took place at the end of the production line," he says. "If anything went wrong, it was too late to correct it."

"Compared to printing technologies, lasers offer good reliability and traceability," says Bak. "Also, customers lose downtime and gain flexibility," he adds. Bak also stresses the significance of a turnkey system for medical marking projects. "We coordinate with suppliers of materials and equipment, integrate everything, and write the system software," he says. Laser marking is also suitable for medical applications because it eliminates the need for aggressive inks, which may pose health risks and are environmentally undesirable. According to Bak, the higher cost of the Lasertec marking system is outweighed by the rising cost of using conventional printing systems to satisfy these concerns.

According to the company, this technology also holds promise for catheter marking.—Benjamin Lichtman

Two Companies Join to Develop Replacement Materials for PVC Compounds

Ferro Corp.'s Filled and Reinforced Plastics Division (Evansville, IL) and Melitek of Copenhagen (Denmark) have struck an alliance to develop polyvinyl chloride (PVC) replacement materials for use in sterilizable medical packaging. This move formalizes a seven-year relationship.

Ferro developed the olefin-based RxLoy line in the early 1990s and licensed the resin technology to Melitek, the exclusive RxLoy supplier in Europe. Ferro describes the RxLoy grades as a cost-effective alternative to PVC in medical packaging applications.


Jointly developed PVC-replacement materials will be used for medical packaging.

"Recent plasticized PVC disposal issues for hospitals, clinics, and HMOs in the United States have increased both the interest level in and evaluation of RxLoy resins," says Joe Klein, director of marketing for Ferro. "Resin economics is less of an issue where there are valid medical reasons for an olefin-based system, such as CAPD bags or IV bags, or for hospitals confronting toxic waste disposal of plasticized PVC versus simply incinerating olefins," adds Klein.

Ferro's olefinic alloy combines radio-frequency weldability with a significantly lower specific gravity, which allows downgauging and improves processing relative to PVC. Other key features include low extractables, high clarity, and excellent barrier properties. The alloys are fully sterilizable by steam, gamma, EtO, and E-beam technologies.

According to Ferro, the European Union is moving more rapidly than the United States in seeking alternative materials to PVC for the medical industry. The company sees its alliance with Melitek as an opportunity to continue developing olefinic alloys for the European market, while benefiting from new and existing specifications secured by Melitek that can be transferred to North America.—Rosemarie A.

Personal Digital Assistant–Based Calibrator Facilitates Data Gathering and Evaluation

Using the Palm OS computing platform, a new line of personal digital assistant (PDA)–based calibrators was displayed at the Instrument Society of America's Exposition earlier this year. Created by Transmation Inc. (Rochester, NY), the 4 x 7 x 1-in. handheld calibrators act as a docking station for the Palm. The Transmation Series 3 PDA calibrators feature a liquid-crystal display touch screen interface that eliminates the need for the buttons and knobs that traditional handheld calibrators require. Combining source and read functions, the documenting calibrators automatically build a device database in the field, can integrate with a facility's existing maintenance practices and systems, and are compatible with all Palm III series PDAs with 2 Mbytes of RAM.

"Our new line of PDA calibrators allow a technician on the plant floor to gather, evaluate, and share information companywide and even worldwide with unparalleled ease, reducing labor time and enhancing performance," says Robert G. Klimasewski, president and CEO of Transmation Inc.

0011p6d.jpgThe new PDA calibrator incorporates Palm OS technology.

To document a calibration, technicians enter device information using a stylus, or select a preexisting device record, and then store instrument identification and input and output information. Users can read measurement data directly from the source circuits or record information manually with the stylus. The PDA software can be used to document nonelectronic calibrations, such as scales and gas analyzers, without the calibrator attached. After the work is completed, users record the information and upload it to a desktop via the HotSync function, creating a permanent certificate of calibration.

"In many facilities, most technicians still carry a pen and paper to the field," says Frank van Vliet, vice president of Transmation Inc. "Recording and storing the data remains a labor-intensive, redundant exercise that could benefit from the marriage of PDA and calibration technology." With the full functionality of a PDA, the calibrators allow technicians to plan their work schedules and appointments and download compatible third-party software, such as conversion and electrical calculators.—Katherine Sweeny
