C. R. Bard has been in the medical device business for more than a century -- it introduced the Foley urological catheter (still one of its top sellers) in 1934. Its products fall into four general therapeutic categories: vascular, oncology, urology, and surgical specialties. Among other things, the company makes stents, catheters, and guidewires used in angioplasties and other vascular procedures; catheters for delivering chemotherapy treatments; and urology catheters and products used to treat urinary incontinence. Its line of specialty surgical tools, made by subsidiary Davol, includes devices used in laparoscopic and orthopedic procedures and for hernia repair.
