Indications for Use

The B&J DVT Calf/Thigh Garments, Models 801/830 Series are designed to increase venous blood flow in at risk patients in order to help lower the risk of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE).

Device Story

B&J DVT Calf/Thigh Garments (801/830 series) are external pneumatic compression sleeves; used with compatible pump systems to provide intermittent or sequentially gradient pressure to patient limbs. Inflation collapses veins to force blood toward the heart; deflation allows vein reopening and reperfusion. Used in clinical settings for DVT prophylaxis. Models vary by limb location (calf vs. thigh) and size. Output is mechanical compression; clinical benefit is reduced risk of DVT and PE in at-risk patients.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including biocompatibility, bladder burst, leak testing, and pressure cyclic testing with B&J pneumatic pumps.

Technological Characteristics

Compression garments consisting of nylon loop, polyester loop, polyurethane foam, polyester tricot, PVC or TPU film, PVC tubing, nylon velcro, polyester/cotton binding, and nylon thread. Available in calf (801) and thigh (830) configurations. Supports intermittent or sequential (3-chamber) pneumatic operation. Dimensions range 14"-42".

Indications for Use

Indicated for at-risk patients requiring increased venous blood flow to reduce the risk of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE).

Regulatory Classification

Identification

A compressible limb sleeve is a device that is used to prevent pooling of blood in a limb by inflating periodically a sleeve around the limb.

Description of the Device [21 CFR 807.92(a) (4)] The 801/830 series of DVT calf/thigh garments are compression devices. When the devices are attached to a pump system, they provide intermittent, sequentially gradient pressure to a patient calf/thigh for the prevention of deep vein thrombosis (DVT). When the compression sleeve is inflated, the veins collapse which forces blood to move upward toward the heart. After compression is complete, the sleeves deflate which allows the veins to reopen and bring oxygenated blood to the calf or thigh. 801 series includes 801M, 801L, 801B, 801P, 801MSQ, 801LSQ, 801BSQ and 801PSQ. 830 series includes 830M, 830L, 830B, 830MSQ, 830LSQ, 830BSQ and 830SSQ. Model variations are distinguished by characters. 801 means calf; 830 means thigh. M means medium size; L means large size; B means extra large size; P or S means small size. SQ means sequential; no SQ means intermittent. For example, 801MSQ means the calf garment is with medium size, and used for a sequential pump. ### 6.
