Abstract: Configurations are described for conducting minimally invasive medical diagnoses and interventions utilizing elongate instruments and assemblies comprising one or more imaging devices, and one or more remote retraction and distraction devices. Retraction and distraction devices, such as balloons, mechanical retraction members, and/or trocar screw geometries may be utilized to access, investigate, and intervene at the joint capsule, or inside of the joint capsule. Imaging devices, such as optical image capture devices, ultrasound transducers, and optical coherence tomography fibers, may be utilized to assist with navigation of the pertinent tools during diagnostic and interventional steps.
