Abstract
Abstract A percutaneous device for performing tracheostomies or cricothyroidectomies having a hollow needle with a sharp distal end. The device includes a flexible dilator slidably positioned over the needle. The dilator includes a conical portion and an annular groove, the apex of which is positioned adjacent the distal end of the needle and the base thereby terminating at the annular groove. A flexible breathing tube is slidably positioned over the dilator for insertion into a trachea or larynx.
