Indications for Use

SaphenaMEDICAL Anti-Embolism Stockings are intended to: - Help to prevent the pooling of blood in the legs by applying controlled pressure to the legs. - Help to prevent Deep Vein Thrombosis (DVT) and, edema and leg discomfort in . individuals subjected to immobility.

Device Story

SaphenaMEDICAL Anti-Embolism Stockings are ready-to-wear, graduated compression garments designed for post-operative, surgical, reclining, or bed-confined patients. Fabricated from nylon and lycra, the stockings apply controlled, uniform graduated compression to the legs to improve capillary and lymphatic drainage and reduce capillary leakage. Compression is highest at the ankle (approx. 18 mmHg), decreasing toward the mid-calf (14 mmHg) and upper thigh (8 mmHg). The device is used in clinical or home settings to manage edema, lymphedema, and prevent DVT by preventing blood pooling. It is non-sterile and latex-free. Healthcare providers or patients use the stockings to provide mechanical support, with sizing based on ankle, calf, and thigh circumferences.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing demonstrated that the device's safety and effectiveness are equivalent to the predicate devices in material content, function, and indication.

Technological Characteristics

Materials: Nylon and spandex (elastane/lycra). Construction: Circular knit. Compression: Graduated (10-20 mmHg range). Form factor: Knee-high and thigh-high styles. Energy source: Passive mechanical compression. Sterilization: Not stated.

Indications for Use

Indicated for post-operative, surgical, reclining, or bed-confined patients to prevent blood pooling, DVT, edema, and leg discomfort in individuals subjected to immobility.

Regulatory Classification

Identification

The knee-high is sized based on ankle and calf circumferences, while the thigh high is sized based on ankle, calf, and thigh circumference fit. {2}------------------------------------------------ For the SaphenaMEDICAL® Anti -Embolism Stocking 510(k) Summary #### Device Description: SaphenaMEDICAL Anti-Embolism Stockings are ready-to-wear for post-operative/ surgical, reclining or bed-confined patients, to help prevent pooling of blood and fluid in the extremities by applying controlled graduated pressure. The fabric used is comprised of nylon and lycra which is used in the predicate devices. The SaphenaMEDICAL Anti-Embolism Stockings provide controlled, uniform graduated conpression, as is provided in all of these substantially equivalent products, starting with more compression circumferentially at the ankle at approximately 18 mmHg (based on average ankle size) then gradually decreases up to the proximal end. (14mmHg at the mid-calf and 8mmHg at the upper thigh) Compression for the SaphenaMEDICAL Anti-Embolism Stockings, as well as all the predicate devices, is provided by lycra that acts circumferentially on the extremity. The gradient compression present in these products helps reduce capillary leakage and improve capillary and lymphatic drainage and/or absorption. Consequently, they can be used to manage the same indications, i.e. edema and lymphedema. The Anti-Embolism Stockings are not made with natural rubber latex. Technological Characteristics: A comparative review of the SaphenaMEDICAL Anti-Embolism Stockings with the predicate A comparative reviour of the objical characteristics, performance and principle of operation were substantially equivalent. | Property | New Device: SaphenaMEDICAL Anti-Embolism Stockings | Anti-Embolism Stockings | Therafirm Anti- Embolism Stockings | Kendall T.ED.
