Oxford Finance LLC (‘Oxford’) announced the closing of a $50 million senior secured term loan with Mainstay Medical Holdings plc (‘Mainstay’ or ‘the Company’), a medical device company focused on commercializing an innovative implantable restorative neurostimulation system, ReActiv8®, for the treatment of disabling mechanical chronic low back pain (‘CLBP’). ReActiv8 is an active implantable medical device that stimulates nerves responsible for activating a key muscle involved in stabilizing the lower back. ReActiv8 is designed to provide therapy for people whose lives are significantly impacted by intractable, mechanical CLBP. Contraction of the muscle can lead to restoration of control over time, allowing the back to recover from CLBP.
