Summary
Brief summary
The ReActiv8 Observational Registry is a multi-center, data collection registry in patients who are being considered for a ReActiv8 implant. At the time of implant, patients must meet the indications and not be contraindicated for ReActiv8. If it is determined that a patient will not be implanted, the patient will be exited from the Registry. Implanted patients will be followed for two years post-activation, at which point they will be exited from the Registry.
The ReActiv8 device is approved by the TGA for use in Australia for the indications above and its implantation in participating centres is standard of care.
