Specializing in medical-grade alloys, a supplier offers bar materials used to manufacture an array of medical device components requiring close tolerances. The company’s AccuRod ground and polished bar stock made from stainless steel, carbon steel and alloys, aluminum, titanium, tool steel, or exotic materials meets custom specifications for size tolerance, straightness, and roundness. In-stock materials include BioDur Type 316LS stainless steel, Custom 455 martensitic stainless steel, and TrimRite stainless steel. The company’s alloys can be provided with tolerances down to 0.000040 in., roundness down to 0.000020 in., and finishes to 2 Ra. The company also offers straightening, cut-length, bar-end chamfering, heat-treating, and inventory management services. In addition, it offers grinding services for customer-supplied components and bars.
Custom-engineered implantable biomedical textiles are available from a manufacturer for use in cardiovascular, orthopedic, tissue engineering, general surgery, and neurology applications. The ISO 13485:2003– and ISO 9001–certified company designs, prototypes, develops, and manufactures textile components using high-performance metallic and polymeric biomedical materials. The textiles are formed using traditional fabrication methods, including weaving, knitting, and braiding. Biomaterial options include polyethylene terephthalate, polypropylene, PEEK, high-performance polyethylenes (UHMWPE), bioabsorbable polymers, PGA, PLLA, PCL, various copolymers, radiopaque materials, low-friction polymers, titanium, nitinol, stainless steel, and hybrid biomaterial combinations.
