Serpentine cutting blade for cutting balloon
First Claim
Patent Images
1. A system for treatment of a vessel lesion comprising:
- an expandable balloon including a proximal waist, a proximal cone immediately adjacent to the proximal waist, a distal waist, a distal cone immediately adjacent to the distal waist, and a body, the body extending between the proximal cone and the distal cone; and
at least one cutting blade engaged to an exterior surface of the balloon, the at least one blade comprising a body region extending along at least a portion of the body of the balloon, a distal end region and a proximal end region;
the body portion of the at least one cutting blade having a substantially serpentine configuration defined by a plurality of interconnected peaks and troughs wherein each trough is in closer proximity to the balloon than each peak, the at least one cutting blade having a lower surface facing the body of the balloon that undulates toward the balloon at the troughs and away from the balloon at the peaks;
the at least one cutting blade extending substantially parallel to a longitudinal axis of the balloon.
