What the 8 Chamber Vest Delivers
The Bio Pants reach areas no boot or sleeve can treat
Clears the Axillary Bottleneck
8-chamber sequential compression directs fluid movement away from the legs, groin, and abdomen — promoting lymphatic drainage and reducing swelling in all affected areas.
Relieves Trunk Lymphedema
200 Denier Nylon Oxford fabric with water-resistant coating ensures the garment withstands repeated therapy sessions while remaining simple to clean and maintain.
Supports Complete Upper-Body Protocols
Front zippers and pull-up straps eliminate the need for caregiver help at every session, giving patients dignity and flexibility in their own recovery schedule.

Frequently Asked Questions
Everything you need to know about the 8 Chamber Vest
The vest is designed for patients with breast cancer-related lymphedema, post-mastectomy swelling, truncal lymphedema, and upper body fluid management needs. It is especially valuable for patients whose arm sleeve therapy has plateaued — this is often because the axillary bottleneck is limiting how effectively fluid can drain from the arm, and the vest addresses that root cause directly.
The vest is most effective as a complement to an arm sleeve, not a replacement. The vest clears the axillary hub and treats the trunk, while the arm sleeve moves fluid from the hand and forearm toward the axilla. Used together they create a complete upper-body drainage circuit. Used alone, the vest addresses truncal and axillary issues but does not treat the distal arm.
The 8 Chamber Vest is compatible with the Bio Compression SC-3008-DL pump, which provides the 8 sequential outlet channels required to drive each vest chamber independently. Using the vest with a 4-channel pump would pair chambers and reduce the precision of the sequential gradient. Contact our team at (612) 360-2490 if you need guidance on pump selection.
The vest should fit snugly across the torso — firm enough to deliver consistent compression without restricting breathing or causing discomfort. Fasten the velcro panels from the bottom upward. Check that the axillary panels sit fully in the armpit crease on both sides. If you are unsure of fit, our support team at (612) 360-2490 can walk you through proper fitting over the phone.
Yes. While the vest is primarily prescribed for lymphedema, it can also be used for post-surgical edema following thoracic procedures, breast reconstruction swelling, and generalized truncal fluid retention. Always follow your physician's or lymphedema therapist's prescription for use with any medical condition.
