A Foley is a catheter with two channels and one tube. The first channel drains urine into a collection bag, while the other channel has a valve on the outside end and connects to a balloon at the inside tip. The balloon is inflated with sterile water when it lies inside the bladder to prevent the catheter from slipping out. McKesson 2-Way 100% Silicone Foley Catheters are ideal for patients with latex allergies and longer term catherization. Silicone provides chemical and thermal stability, low surface tension and hydrophobicity.
