VEINOPLUS®
Activating the Calf Pump Mechanism
VEINOPLUS® reactivates the calf muscle pump to increase local blood circulation — using Second Heart Technology™, a proprietary low-frequency waveform that produces rhythmic calf contractions without painful muscle fatigue.
VEINOPLUS® is an FDA-cleared Class II neuromuscular stimulator. Coverage may be available through Medicare, commercial plans (e.g., Blue Cross Blue Shield), and the VA & federal health systems — eligibility, medical necessity, and reimbursement are determined solely by each payer and plan. Available to the VA and federal health systems on the Federal Supply Schedule (FSS 36F79723D0020).

VEINOPLUS® with Second Heart Technology™
A pocket-sized, FDA-cleared NMES device built around a proprietary low-frequency waveform. Each rhythmic calf contraction increases local blood circulation — without painful muscle fatigue.
Engineered by its inventor, Dr. Jozef Cywinski, VEINOPLUS® uses a proprietary low-frequency waveform that sets it apart from general EMS or TENS devices:
Simple. Portable. Patient-Administered.
Mechanism, Safety & Prescribing
VEINOPLUS® is a pocket-sized, lightweight, battery-powered EMS device. Using Second Heart Technology™, it delivers low-frequency, low-voltage impulses through two electrodes on the calf, producing rhythmic contractions that activate the calf muscle pump — the body's "second heart." Its proprietary signal waveform is designed for patient comfort during stimulation.
Mechanism of Action
- Delivers low-frequency impulses that trigger rhythmic calf muscle contractions, enhancing both venous return and arterial inflow
- Increases local blood circulation, delivering oxygenated blood to the lower leg
- Helps move fluid out of the lower leg during use
- Low-intensity impulses designed for patient comfort
- Rare, self-limiting mild skin reactions
- Non-invasive, drug-free; patient self-administered
- FDA-cleared Class II device
- Cardiac pacemaker or other implanted electronic device
- Active DVT at the treatment site
- Severe arterial insufficiency
- Uncontrolled congestive heart failure
- 60-minute sessions, per physician direction
- May be combined with compression therapy
- Portable: patient self-administers at home or during travel
- Rx only — federal law restricts sale to/on the order of a physician
Clinical Evidence
VEINOPLUS® technology has been studied in 10 peer-reviewed publications and presented at 49 international congresses, in collaboration with globally recognized vascular research teams. Published data demonstrate increased arterial inflow and venous return in the lower limbs during stimulation.
DVT Prevention
Use for at least 100 min/day (5 sessions × 20 min) significantly reduced post-surgical DVT incidence in high-risk patients vs. standard care alone.
Venous Blood Flow
In duplex-ultrasound studies, VEINOPLUS® increased peak venous velocity up to 11× and total venous volume flow up to 12× (20 → 240 ml/min) vs. passive baseline.
Calf Muscle Activation
Rhythmic, stimulated calf contractions activate the muscle pump — increasing local blood circulation and maintaining muscle activity even when voluntary exercise isn't possible.
- Improves local blood flow and oxygenation in PAD and diabetes
- Activates the calf pump for healthier venous return
- Prevents venous thrombosis in post-surgical patients
- Reduces disuse muscle atrophy from inactivity, obesity, or immobilization
- Supports rehabilitation after orthopedic or abdominal surgery
VEINOPLUS® for Veterans
An FDA-cleared, pocket-sized electro-muscular stimulation (EMS) device available to the VA and federal health systems on Federal Supply Schedule. Used by 150,000+ patients across 40 countries, supported by clinical studies since 2004.
