This IVT provokes rhythmic vasodilation and compression and, in a purely physical way, naturally increases blood flow [1–3, 9]. This improves the macro- and microvascular perfusion parameters of the lower extremity and, as shown experimentally and clinically, increases nutritive oxygen supply [1, 4, 6, 7]. During rhythmic dilation/compression, shear forces arise at the vessel wall; the endothelium converts these mechanical stimuli into increased NO release (vasodilation, anti-atherogenic signaling pathways, activation of endothelial nitric oxide synthase) [1, 3, 8, 9].
A central mechanism of IVT is the stimulation of NO release via arterial shear forces acting on endothelial cells. The endothelium acts as a mechanotransducer that converts shear forces exerted by blood flow into chemical stimuli such as the formation of NO [4–6, 9]. NO is a potent vasodilator that exerts anti-atherogenic as well as anti-proliferative effects on the arterial wall. [8–10]
IVT leads to a significant improvement in microcirculation through several synergistic mechanisms [7–9]. Alternating application of negative pressure induces vasodilation, particularly of venous capillaries, thereby stimulating arterial perfusion. Experimental studies show that vacuum therapy increases capillary diameters and blood volume [10].
Treatment with IVT is associated with marked capillary end-dilatation and capillarization, together with an increase in micro- and macroperfusion in the lower extremities. The widening of the smallest vessels during the negative-pressure phases allows more blood to reach the muscle and results in an increase in arterial blood flow [4].
Endothelial Protective Functions: IVT activates multiple endothelial protective functions through the physical stimulation of the vessel wall [9, 12]. Laminar shear forces lead to increased expression of endothelial NO synthase in endothelial cells. These shear-stress-induced changes are potentially atheroprotective and contribute to vascular health [8, 11].
Vascular Training and Adaptation: Intermittent/negative-pressure applications support edema reduction and improve cutaneous microcirculation [6, 7, 11].
Neurological Protective Responses: The physical change in pressure activates baroreceptors and sympathetic responses, leading to adaptation of the cardiovascular system [13]. When negative pressure is reached rapidly, arterial baroreceptors are activated, which respond to mean arterial pressure [13, 14].
Optimization of Nutrient and Oxygen Supply: IVT activates cellular metabolic processes through improved oxygen and nutrient delivery. The increased microcirculation leads to better oxygenation of cells and simultaneously supports the removal of metabolic waste products and toxins. These processes are fundamental for maintaining cellular homeostasis and regeneration [8, 11].
Mitochondrial Function and Energy Metabolism: NO influences myocardial oxygen consumption and can modulate the mitochondrial respiratory chain. Increased microcirculation optimizes mitochondrial respiration and reduces oxidative stress. The improved oxygen supply through IVT can indirectly support mitochondrial function. NO influences myocardial oxygen consumption and can modulate the mitochondrial respiratory chain. Increased microcirculation optimizes mitochondrial respiration and reduces oxidative stress. [8]
Cellular Regeneration and Metabolic Activation: Improved blood flow enhances the removal of metabolic end products and brings in fresh, oxygen- and nutrient-rich blood. This leads to activation of cellular metabolism and supports regenerative processes at the cellular level [11].
Anti-inflammatory Effects: IVT exhibits anti-inflammatory effects through the modulation of inflammatory processes. In patients with inflammatory diseases, a reduction of the acute inflammatory response by 37.5% was observed. The therapy leads to lower concentrations of pro-inflammatory cytokines in the blood serum [15].
Central cytokines in the regulation of inflammation are IL-1 and TNF, which are considered key pro-inflammatory cytokines. IVT can reduce the release of these inflammatory mediators and contribute to an improved inflammatory status [16].
Tissue Healing and Angiogenesis: IVT accelerates wound healing through several synergistic mechanisms. Improved microcirculation increases oxygen supply to the wound area, which is essential for healing processes [17]. The therapy stimulates endothelial proliferation and angiogenesis, restores the integrity of the capillary basement membrane, and reduces vascular permeability [18, 19].
Studies show that vacuum therapy promotes the formation of granulation tissue and mechanically approximates wound edges [19, 20].
Lymphatic Drainage and Edema Reduction: IVT acts as an effective lymph drainage method through its physiological action on the “removal of lymph-obligatory loads.” This leads to pronounced reduction of edema and supports tissue regeneration [11].
Reduction of Oxidative Stress: Oxidative stress arises from an excess of free radicals, which are responsible for cellular damage and are associated with skin aging, inflammation, and disease. IVT can reduce age-related cellular damage over the long term by improving microcirculation and oxygen supply [8].
Antioxidants play an important role in neutralizing free radicals, and optimized blood flow can improve the supply of these protective substances [8].
Vascular Aging and Endothelial Function: Decreased activity or dysfunction of endothelial NO synthase promotes the development of vascular diseases such as atherosclerosis. By stimulating NO release, IVT can counteract these aging processes [8].
Cellular Regeneration and Repair Mechanisms: The physical stimulation by IVT activates repair mechanisms and supports the maintenance of cellular integrity. The therapy can slow the accumulation of cellular damage and promote cellular regeneration. Hypoxic conditions, as they occur in vacuum therapy, can promote stem cell mobilization and support regenerative processes [4].
Systemic Anti-Aging Effects: IVT shows systemic effects on health by optimizing fundamental transport pathways for oxygen, nutrients, and waste products. Its non-invasive nature and the absence of side effects make it an attractive option in preventive and regenerative medicine. The technology ideally complements other longevity interventions, as it operates at the physical level and establishes the basic prerequisites for cellular health.

The Intermittent Vacuum Therapy (IVT) of the Vacustyler® Avantgarde operates with rhythmically alternating negative and positive pressure phases on the lower body. The resulting shear forces activate the eNOS/NO axis, improve microcirculation, promote venous return and lymphatic flow, and modulate inflammatory processes. The integrated photobiostimulation module (Red/NIR ≈ 630–850 nm) complements IVT at the cellular level via mitochondrial mechanisms. In longevity medicine, IVT primarily addresses the Hallmarks “Altered intercellular communication,” “Chronic inflammation,” “Mitochondrial dysfunction,” and indirectly “Cellular senescence” [1–6,10–16].
IVT is a non-invasive procedure with roots in space/sports and rehabilitation medicine. The objective is to improve perfusion, endothelial function, and fluid dynamics of the lower extremities – with relevance for regeneration, wound healing, venous-lymphatic disorders, as well as metabolic and aesthetic applications [1–9,14–16].
1) Pressure Phases (IVT): Alternating negative and positive pressure phases (typ. 2–30 s) generate shear forces at the vascular endothelium, increase transmural pressure gradients, and shift blood/lymph volume. Negative pressure leads to vasodilation/volume increase, normal/positive pressure to return flow promotion [6–9,10–12].
2) Endothelium & NO: Mechanotransduction increases eNOS activity and NO release → improved vascular elasticity, anti-atherogenic effects, better FMD [10–12].
3) Microcirculation: Capillary recruitment, flow velocity, and local blood volume increase; tissue perfusion improves measurably [6–9,13].
4) Lymphatic Activation: The cyclic volume shift relieves the lymphatic system; edema and tissue pressure decrease [14–16].
5) Neuromodulation: Baroreceptor and sympathovagal responses support orthostatic regulation [20–21].
6) Integrated Photobiostimulation (Red/NIR): The LED module (≈ 630–850 nm) is integrated into the device and can be activated in parallel. Target mechanisms: cytochrome c oxidase activation, ATP↑, ROS/inflammation↓, fibroblast activation, and tissue tightening [17–19].
Common Indications: Chronic microcirculatory disorders; venous insufficiency, lymphedema/edema; wound healing, postoperative and athletic regeneration; skin/tissue tightening (with activated PBM module); “Longevity baseline”: perfusion- and metabolism-supporting base intervention [6–9,14–19].
Contraindications (Examples): Acute thrombosis, decompensated heart failure; acute infections/fever, active bleeding/wounds (without protection); pregnancy (center-dependent); always seek medical clearance.
