Harold James Charles ‘Jeremy’ Swan (1922 – 2005) was an Irish cardiologist, innovator and a prominent figure within the world of cardiology.
Swan was a celebrated personality of the American College of Cardiology, an avid sportsman and amateur middle weight boxer. He was awarded the highest degree of academic achievement by the college.
Although he is best remembered as co-inventor of the Swan-Ganz catheter with William Ganz at Cedars-Sinai Medical Center in 1970, his scientific contributions are extensive and recognised by the numerous awards listed in the biography below.
The inspiration for the catheter was derived from sailboats Swan observed at Santa Monica Beach in 1967. His original concept was to attach a small sail at the end of the catheter; allowing it to glide through the right atrium, right ventricle and eventually to the pulmonary artery. In 1970 it would be later modified with a balloon tipped catheter that Swan, William Ganz and others would publish a report on1. The advent of quantitative haemodynamic bedside assessment afforded an insight into the physiology of the critically ill and guided therapy. Almost 40 years later, the Swan-Ganz catheter is still in use in cardiac surgery and critical care.

Swan-Ganz catheter – pulmonary artery catheter (1970)
Pictured below is the “extruded polyvinyl-chloride catheter 1.7mm in outer diameter” with the balloon tipped catheter and “attached to a strain-gauge catheter.” The pulmonary artery was accessed via “antecubital-vein cutdown” during the inception.
