Medical devices advance procedures

Engineers at Metric Medical Devices near San Antonio, Texas, needed a sterile, disposable, biocompatible housing for the company’s Super Stable Classic, a syringe-sized device that quickly implants nitinol staples into bone, allowing for shorter, less invasive surgeries, and speedier patient recovery times.

Offered as a complete procedure kit, the Super Staple offers instantaneous bone compression force in common surgeries such as hand and foot bone fragment and osteotomy fixation, fixation of proximal tibial metaphysis osteotomy, and adjunctive fixation of small bone fragments.

After conducting property evaluations for several options for the device house, Metric Medical selected Makrolon Rx2530 from Bayer MaterialScience LLC because of the material’s high strength, temperature stability, transparency, and biocompatibility.

“The performance of Makrolon Rx2530 has been excellent,” says Dan Wadsworth, vice president, research and development, Metric. “The Bayer MaterialScience team was remarkably responsive during the material selection and design phase.”

In addition to assisting with material selection, Bayer also conducted testing to demonstrate the material’s compliance with ISO-10993 and U.S. Food and Drug Administration biocompatibility guidelines.

“We worked closely with Metric, providing guidance related to selection of the Makrolon polycarbonate grade that best met the stringent requirements – including toughness and biocompatibility – for this application,” says Fred Woods, field market development, Polycarbonate, Bayer MaterialScience.
