Putnam Plastics Corp. (Dayville, CT), is commercializing a proprietary process for manufacturing custom monofilament fibers up to 0.100 inch (2.54 mm) in diameter from nylon, polypropylene and other materials.
The goal is to use the large diameter medical monofilament for x-ray and MRI applications as a metal replacement.
Oriented, large-diameter fibers provide substantial strength for applications requiring x-ray transparency or non-magnetic properties for magnetic resonance imaging (MRI), according to Putnam Plastics.
"The convergence of minimally invasive devices and medical imaging technologies are increasing demand for non-metallic components made from high performance materials. These emerging device solutions are custom by definition," said Ray Rilling, general manager at Putnam. "There is no off-the-shelf source for medical monofilaments with diameters greater than 0.025 inch (0.64mm). Our monofilament lines are built for custom medical applications, with capabilities for processing the broadest range of sizes and materials for device prototypes through production."...
