    "device_name": "Autologous Adult Stem Cell Therapy Procedure",
    "goal": "Treat joint, spinal, heart, lung, and other chronic conditions by using the patient's own adipose-derived mesenchymal stem cells to promote tissue repair and regeneration.",
    "problem_addressed": "Chronic inflammation and degeneration of joints, spine, heart and lung tissues, and limited regenerative capacity of adult patients; also regulatory barriers imposed by the FDA.",
    "concept_summary": "The therapy extracts a small amount of adipose (fat) tissue from the patient via liposuction, isolates mesenchymal stem cells by centrifugation, purifies them, and re-injects them (IV drip or local injection) into the same patient to stimulate endogenous healing, angiogenesis, and tissue regeneration.",
    "detailed_description": "A minimally invasive outpatient procedure uses local anesthesia to make a shallow incision, withdraws adipose tissue, spins it at high speed in a centrifuge to isolate stem cells, purifies the cell fraction, and delivers the autologous stem cells back to the patient via injection or IV. The process avoids the use of patented drugs, relies on the patient's own cells, and is claimed to have a >90% success healing rate for joint and spinal conditions, with reported benefits for heart and lung issues.",
