Abstract
An apparatus for performing a medical procedure on a structure, such as a lesion, in a vessel. The apparatus includes a catheter shaft having a frangible portion with a scoring element adapted for scoring the lesion when the frangible portion is broken. An expandable element, such as an inflatable balloon, may be provided for breaking the frangible portion, which then allows the scoring element to move radially outwardly toward the structure or lesion in the vessel. Related methods are also disclosed.
