Device and method for converting a balloon catheter into a cutting balloon catheter

摘要

A lesion treating device for converting a standard balloon catheter into a cutting balloon catheter is provided. The device includes a longitudinal housing such as a tube which is sized to be inserted into a lumen of the balloon catheter and cutting wires disposed within the longitudinal housing in an undeployed position. When the longitudinal housing is moved relative to the cutting wires, the cutting wires extend out of the longitudinal housing. The balloon of the balloon catheter is then moved under the deployed cutting wires and inflated to convert the standard balloon catheter into the cutting balloon catheter.
