According to LoveEnterprise, the origins of Integra are related to Johnson & Johnson, but Integra has now evolved into an independent company with its own brand and product line. Intergrad is a reputable company in the field of neurosurgery and burns medical devices, and its predecessor was Johnson & Johnson's Codman, so some people may mistakenly believe that the two companies are the same.
However, Integra has its own R&D and manufacturing capabilities in the field of neurosurgical implants and has a broad reputation in the medical technology field.
