Boston Scientific Corporation (NYSE: BSX)

Boston Scientific is a global medical device company focused on interventional medical specialties including cardiology, urology, endoscopy, and neuromodulation. The company's products range from coronary stents and pacemakers to devices for chronic pain management and urological conditions. Boston Scientific has become particularly dominant in electrophysiology, the treatment of heart rhythm disorders.

Boston Scientific sells single-use and implantable medical devices to hospitals and ambulatory surgery centers globally. Revenue is driven by procedure volumes, new product launches, and geographic expansion into emerging markets where access to interventional procedures is growing rapidly.

Founded in 1979 by John Abele and Pete Nicholas, Boston Scientific grew through the development of less-invasive medical devices. The $27 billion acquisition of Guidant in 2006 was a bruising battle with Johnson & Johnson that saddled the company with debt. A turnaround under CEO Mike Mahoney starting in 2012 restored growth and profitability.
