Abstract
The invention is an integrated device and improved method for percutaneous placement of a tracheostomy tube into a patient which includes a film sheath everted from a pusher moved through a guide that is positioned over an incision site in a patient's neck. The pusher moves through an incision, which may be preexisting or created by the device, into the patient's trachea, laying down the film sheath as it advances. The film and pusher may effect blunt dissection of the patient's tissue, and the device may optionally include a blade(s), needle or other cutting tool and/or the tracheostomy tube itself so that the tracheostomy can be completed with fewer procedural steps and surgical instruments.
