Zebra Medical Technologies has developed a clinically deployable micro endoscopy system for minimally invasive, real-time imaging of sarcomere structures in human muscles without the need for exogenous dyes or contrast agents. Using Zebra Medical's tool surgeons can assess sarcomere lengths in real time, improving the planning, execution, and follow up in surgical interventions for muscle repair. The firm's technology also has potential applications related to the treatment of multiple neuromuscular disorders and for cellular imaging of skin, cartilage, bone and tendons. Systems for research use are already being made available and are for sale, Principals of the irmare exploring collaborations with companies developing therapies to rejuvenate muscle and treat amyotrophic lateral sclerosis (ALS) and sarcopenia.
