Last month, Liquidmetal Technologies received long-term implantation results from parts 3, 10, 6 and 11 of the ISO 10993 (Biological Evaluation of Medical Devices) suite of tests, which include evaluation of genotoxicity, sub-chronic systemic toxicity and pyrogenicity, the company said yesterday.
Liquidmetal Tech alloy LM105 passed all of these tests well within the allowable limits. These results – combined with previously completed tests from ISO 10993 parts 10, 11, 4, and 5 which cover sensitization, irritation, acute systemic toxicity, hemocompatibility and cytotoxicity – indicate that the Liquidmetal process is compatible with a wide range of medical device requirements including long-term implants.
“The results of these tests are very exciting and it positions the company well to engage medical device customers in a broad range of implantable device applications including, cardiac rhythm, cochlear, spinal, and orthopedic implants among others. The company will now focus on partnering with medical implant manufacturers to identify specific applications to further explore the use of Liquidmetal,” said Paul Hauck, executive vice president of sales and marketing at Liquidmetal Technologies.
Rancho Santa Margarita, Calif.–based Liquidmetal Technologies develops bulk amorphous alloys – unique materials that are distinguished by their ability to be injection molded and die cast into high performance applications for a broad range of markets.
