Abstract
A scoring balloon catheter includes a scoring balloon, a distal control balloon positioned distal of the scoring balloon, a proximal control balloon positioned proximal of the scoring balloon, and a scoring element coupled to the proximal and distal control balloons. The scoring balloon is configured to expand radially and contact the scoring element.
Claims19
A scoring balloon catheter for treating a site within a body lumen, the balloon catheter comprising:
- a scoring balloon;
- a distal control balloon distal of the scoring balloon;
- a proximal control balloon proximal of the scoring balloon;
- a scoring element coupled at a proximal end thereof to the proximal control balloon and at a distal end thereof to the distal control balloon,
- wherein with the proximal and distal control balloons each in an inflated configuration and the scoring balloon in an uninflated configuration, the scoring element is taut between the first and second control balloons and not in contact with the scoring balloon,
- wherein the scoring balloon is configured to expand to contact the scoring element, and
- wherein the scoring balloon is configured to be expanded separately from the proximal control balloon and the distal control balloon.

A method for scoring a lesion within a patient's vasculature, the method comprising the steps of:
- delivering a scoring balloon catheter through the vasculature to the lesion, wherein the scoring balloon catheter includes a scoring balloon, a distal control balloon, a proximal control balloon, and a scoring element coupled at a proximal end thereof to the proximal control balloon and at a distal end thereof to the distal control balloon;
- positioning the scoring balloon catheter such that the scoring balloon is positioned within the lesion;
- inflating the proximal and distal control balloons such that the scoring element becomes taut, wherein the scoring balloon is uninflated and not in contact with the scoring element;
- and
- after inflating the proximal and distal control balloons, inflating the scoring balloon to contact the scoring element and force the scoring element radially outward relative of the longitudinal axis of the scoring balloon catheter such that the scoring element engages the lesion.
