Comfort and Integrated K2 Vacuum

Vacuum systems can be a great benefit for K2 patients, allowing them the ability to reduce limb volume fluctuations and pistoning.[1,2,3] College Park’s Integrated Vacuum Technology (iVT) is designed to pull up to 20 inHg in fewer steps, allowing patients to efficiently achieve optimal vacuum.* With enhanced suspension to the residual limb, this low-profile foot may improve comfort and overall limb health. The Celsus iVT also features Integrated Spring Technology (iST®) and Intelliweave® composites for energy, strength, and flexibility.

*Results may vary based on impact and activity. Maximum attainable vacuum ranges from 18-22 inHg.
