Dr. Ciaglia was concerned with the number of complications patients experienced using a surgical (or open) tracheostomy technique. He knew that there had to be a better way. One day, at St. Elizabeth Medical Center in Utica, NY, Dr. Ciaglia happened to see a colleague performing a percutaneous kidney stone removal procedure with a set of straight serial dilators, the Amplatz Renal Dilator Set. This device used a minimally invasive, over-the-wire, Seldinger technique to access the kidney.
Realizing that the same principle of using sequentially larger dilators could be used for tracheostomy, Dr. Ciaglia wanted a closer look at those renal dilators. As good fortune would have it, the Cook Medical representative for this hospital happened to be supporting the procedure that day.
Dr. Ciaglia worked with Cook to modify the renal dilator set to better accommodate the anatomy of a trachea. The first percutaneous dilatational tracheostomy (PDT) set was launched in 1987 (see image at right). The first Ciaglia Percutaneous Tracheostomy Introducer Set changed an open surgical technique into a minimally invasive one.
The first PDT product was a set of seven serial dilators that incorporated an angled, tapered tip to accommodate the anatomy of a trachea.
