New production processes and significant testing was required to make these materials eligible for implants. These efforts included meeting the relevant aspects of the current Good Manufacturing Practice (GMP) guidelines of the Food & Drug Administration’s 21CFR Part 820 Quality Systems Requirements and ensuring manufacturing operations are in compliance with relevant aspects of the ISO 13485 Quality Management System for the manufacture of medical devices.
OEMs evaluating the new materials include Zimmer Medical, a leading orthopedic supplier based in Warsaw, IN. The market for knee implants alone is $5.2 billion annually and is growing at an 8 percent clip, estimates Zimmer Chief Financial Officer James T. Crines.
