The Portex Per-fit percutaneous kits are designed to permit a safe, fast, and cost-effective percutaneous tracheostomy procedure with minimal complications. The Per-fit flexible PVC tube features a tapered distal tip and a low-profile cuff designed to reduce insertion force, and more readily conform to the individual patients anatomy. The obturator/dilator is engineered to fit the tube snugly, allowing an easier transition through the tissue into the trachea. The Per-fit kits feature a patented Portex percutaneous tracheostomy tube, a specially designed and sized obturator/dilator, and procedural dilators to facilitate optimum technique, in a complete, double-deck tray with all preparation and procedural components conveniently organized.
