Abstract
Abstract This invention relates to an angioplasty device that is formed from a hollow metallic tube, a balloon affixed adjacent the distal end of the tube and being in fluid communication with the lumen of the tube, a flexible distal segment connected to the distal end of the tube and a removable hub connected adjacent to the proximal end of the tube. The tube is preferably formed from a superelastic material such as nickel-titanium alloy. This invention also relates to various methods of using this angioplasty device.
