Abstract
The present invention is a device for creating a transection in a coronary artery. Structurally, the present invention includes an inflatable balloon mounted at the distal end of a catheter. A single blade is mounted to project radially from the surface of the balloon and is aligned with the balloon's longitudinal axis. Additionally, a series of radio-opaque markers are distributed on the balloon's surface. Operationally, the balloon is advanced, using the catheter, until it is positioned at the approximate site of the desired transection. An X-ray imaging system is then used to visualize the radio-opaque markers, allowing the balloon and blade to be oriented radially and longitudinally at the location required for the transection. The balloon is then inflated, forcing the blade to incise the artery wall and creating the desired transection. The transection creates a new artery composed partially of the old artery and partially of the surrounding fibrous tissue.
