First Claim
Patent Images
1. A method for manufacturing a cutting balloon catheter, comprising the steps of:
- providing a joining member;
providing a metallic cutting blade having a longitudinal axis, the cutting blade having a cutting surface and a base having a lower surface, the base including an interlocking structure defined by a plurality of openings formed in the metallic cutting blade along the base such that the openings extend through the lower surface and also an imaginary plane perpendicular to the longitudinal axis which passes through one of the plurality of openings also passes through material of the base located between the opening and the lower surface of the base;
softening the joining member;
positioning the cutting blade adjacent the joining member so that the interlocking structure is submerged within and interlocked with the joining member;
solidifying the joining member so that the cutting blade and the joining member are secured to one another; and
attaching the joining member and the cutting blade to an angioplasty balloon.
