Abstract
A removable stylet for use in the introduction of cannulae into a vessel or chamber of a body for medical procedures, and a retrograde coronary sinus perfusion cannula using such stylet. The stylet is used to guide the cannula during insertion, and includes a proximal relatively stiff end that can be manually manipulated by the attending physician to guide the stylet. On the distal end of the stylet is a relatively flexible portion that can be shaped into various curves and which is form-retaining while retaining flexibility.
