Predicting individual responseWhile 79% achieve remission, 21% do not; identifying non-responders before treatment would spare unnecessary burden.
Maintaining remission after treatment5-day intensive therapy produces remission, but long-term sustainability requires follow-up protocols and potentially booster sessions.
Physics limits
TMS penetration depthMagnetic stimulation only reaches cortical and superficial subcortical regions; deep brain structures remain inaccessible without invasive methods like DBS.
Individual neuroanatomy variationBrain anatomy and circuit organization vary between individuals; even with fMRI guidance, optimal targeting depends on the precision of mapping and stimulation coil positioning.
How it works
3 parts
Brain Mapping
Personalized target selection
fMRI scan identifies the patient's unique depressive neural circuit, determining the optimal brain region for stimulation targeting.
Stimulation
Accelerated theta-burst TMS
Magnetic coil delivers theta-burst pulses for 10 minutes every hour, 10 times per day for 5 days at personalized intensity.
Personalization
Real-time adaptive tuning
Algorithms continuously adjust stimulation parameters based on brain response to optimize treatment outcome.
SAINT accelerated TMS, depression therapy, precision neuromodulation
Magnus Medical develops SAINT (Stanford Accelerated Intelligent Neuromodulation Therapy), an FDA-cleared 5-day rapid-remission therapy for treatment-resistant depression using precision transcranial magnetic stimulation (TMS). Based on research from Stanford's Brain Stimulation Lab.
Magnus Medical raised $90.7M including a $25M Series A co-led by Jazz Venture Partners and Red Tree Venture Capital.
SAINT achieved 510(k) FDA clearance and Breakthrough Device Designation for rapid remission in Major Depressive Disorder.
The therapy uses fMRI mapping and accelerated theta-burst stimulation (aTBS) for rapid remission in 5 days.
