The Arch Koh-Efficient combines the Koh Cup and the Colpo-Pneumo Occluder balloon into one device for easy loading onto the Advincula Arch handle, as well as rapid and accurate clinical positioning. The sterile, single-use device is available in four sizes to suit your patient's anatomy and is offered in both stainless steel (for harmonic scalpel and laser procedures) and Ultem (for use with electro-surgical cutting devices).
