BrainsWay Deep TMS

Advanced H-Coil technology delivers deeper, broader brain stimulation tailored to the neural network involved.

What is BrainsWay Deep TMS ?

BrainsWay Deep TMS is an advanced, non-invasive therapy that uses patented H-Coil technology to stimulate deeper and broader regions of the brain than conventional TMS. The coil sits inside a cushioned helmet worn on the head and delivers magnetic pulses through the scalp — no surgery, no anaesthesia, no medication.

What sets Deep TMS apart is that it is not a single device with a single target. BrainsWay’s platform uses a family of purpose-built coils, each engineered to reach the specific network involved in a particular condition. The coil is chosen for the patient, not the other way around.

One Platform,
Three Targeted Coils

Three purpose-built H-Coils target distinct brain networks, allowing BrainsWay Deep TMS to address depression, OCD, anxious depression, addiction, and smoking cessation with precision.
Understand the Process
  • H1 Coil — Depression
  • H7 Coil — OCD and Anxious Depression
  • H4 Coil — Addiction and Smoking Cessation

H1 Coil — Depression

Engineered to stimulate the dorsolateral prefrontal cortex with broader bilateral coverage, the H1 Coil is the original Deep TMS coil for major depressive disorder. It engages the wider mood-regulating network rather than a single cortical point, which is why it remains effective even for patients who have not responded to multiple medications.

H7 Coil — OCD and Anxious Depression

The H7 Coil reaches the medial prefrontal cortex and anterior cingulate cortex, structures central to obsessive-compulsive symptoms and to depression accompanied by anxiety. It holds FDA clearance for OCD and, separately, for major depressive disorder including comorbid anxiety. Notably, some patients who plateau on H1 stimulation respond when switched to H7.

H4 Coil — Addiction and Smoking Cessation

The H4 Coil stimulates the bilateral prefrontal cortex and insula — regions tied to craving, reward, and compulsive use. It is FDA-cleared as an aid to short-term smoking cessation in adults, making Deep TMS one of the few non-pharmacological options in addiction care.

Why Choose Buddhi Clinic for Deep TMS

Each H-Coil delivers repetitive magnetic pulses that penetrate deeper cortical and subcortical regions, activating an entire network rather than an isolated patch of surface tissue. This improves communication between brain cells and encourages neuroplasticity — the brain’s natural capacity to reorganise and form healthier connections.
By restoring balanced activity in underactive or dysregulated circuits, Deep TMS supports improvements in mood, motivation, impulse control, and cognitive function. Because the depth and shape of the field differ between the H1, H7, and H4 coils, the same platform can address very different clinical presentations with equal precision.

Precision Brain Stimulation for Targeted Treatment

Deep TMS therapy in Chennai at Buddhi Clinic follows a structured clinical protocol to ensure safe, accurate, and effective brain stimulation.

Mapping the Brain Before Treatment

  • Detailed clinical evaluation to determine suitability for Deep TMS
  • Diagnostic assessment to identify which coil — H1, H7, or H4 — matches the target network
  • Motor threshold determination to personalise stimulation intensity for that coil
  • Explanation of the therapy process and session expectations
  • Comfortable helmet fitting and patient positioning before starting

Delivering Controlled Magnetic Pulses

  • Treatment delivered through a cushioned helmet housing the selected H-Coil
  • Repetitive pulses stimulate deeper and broader brain regions simultaneously
  • Intensity, frequency, and protocol adjusted to the coil and the patient
  • Sessions typically last around 20 minutes
  • Patients remain awake and alert throughout and can resume normal activity immediately

Monitoring Progress and Response

  • Assessment of patient comfort and tolerance after each session
  • Structured symptom tracking using validated clinical scales
  • Adjustment of stimulation parameters where needed
  • Option to switch coils if response plateaus — for example, H1 to H7 in resistant depression
  • Continuation of sessions as part of a complete treatment plan

Key Benefits

  • Non-invasive, non-systemic brain stimulation therapy
  • Condition-specific coils rather than a one-size-fits-all approach
  • Drug-free, with no sedation and no systemic side effects
  • Improves mood, cognition, and behavioural regulation
  • No downtime — comfortable outpatient sessions
  • Supports long-term neuroplasticity and sustained recovery
  • An accelerated treatment option, called SWIFT™ Deep TMS, is also FDA-cleared, shortening the acute treatment phase from 4 weeks to 6 days.

Reaching Deeper Brain Networks and Supporting Neuroplasticity

Access to the full BrainsWay coil range is what turns Deep TMS from a single treatment into a genuinely individualised one. At Buddhi Clinic, the decision of which coil to use — and when to change it — is made by clinicians who work across neurology, psychiatry, psychology, and rehabilitation together, rather than by a single specialist working in isolation. That integrated model matters most for the patients who arrive here after other treatments have fallen short: the person whose depression has resisted several drug trials, the patient whose OCD has not yielded to therapy alone, the smoker who has relapsed repeatedly. Deep TMS is positioned within a broader plan at our clinic — alongside cognitive therapy, counselling, and rehabilitation — because stimulation works best when the rest of a person’s care is pulling in the same direction.

Every patient begins with a detailed assessment that determines suitability, identifies the target network, and sets the stimulation protocol. Progress is measured, reviewed, and adjusted throughout. It is this combination — advanced technology, multidisciplinary judgement, and close follow-up — that makes Buddhi Clinic a trusted destination for Deep Transcranial Magnetic Stimulation in Chennai.

Frequently Asked Questions (FAQs)

Deep TMS is generally well tolerated. Patients may feel tapping or mild sensations on the scalp during stimulation. Comfort is monitored throughout the session, and settings can be adjusted when needed.
The number and frequency of sessions depend on the condition being treated, individual response, and the protocol recommended by the clinical team. Your treatment plan is determined after assessment and reviewed as therapy progresses.
Some patients may experience temporary scalp discomfort or a mild headache following treatment. Your clinician will discuss potential side effects and suitability with you before therapy begins.
In many cases, Deep TMS can be provided alongside existing treatment. However, medications should not be started, stopped, or changed without discussing them with the treating clinician.
Response varies from person to person. Some patients may notice changes during the treatment course, while others may experience improvement more gradually. Progress is monitored throughout the program.
Deep TMS may not be appropriate for everyone, particularly individuals with certain metallic or electronic implants in or near the head. A detailed clinical and safety assessment is completed before treatment.
The duration of improvement varies based on the condition, individual response, and other aspects of care. Some patients may require follow-up or maintenance sessions as recommended by their clinician.
Deep TMS does not typically require sedation or recovery time. Most patients can return to their usual daily activities after a session, subject to individual clinical advice.
