Abstract: A method for fabrication of a cutting balloon assembly is described. The method includes providing a predetermined number of filaments having predetermined properties, diameter and length and fabricating a scoring mesh on a weaving jig having a plurality of pins disposed circumferentially about the jig's surface. The fabrication of the scoring mesh includes placing the filaments between the pins and interlacing the filaments to form a scoring mesh by interweaving and intertwining at least a part of filament to form one or more permanent links with neighboring filaments. The fabrication of the scoring mesh also includes forming distal and proximal filament loops that protrude from the mesh distal and proximal ends, respectfully. The scoring mesh is mounted on an expandable balloon mounted on a distal end of a delivery catheter.

Abstract: A cutting balloon assembly and a method for fabrication of the assembly is described. The cutting balloon assembly comprises a delivery catheter, an expandable balloon mounted on the catheter distal end, and a scoring mesh disposed around the expandable balloon. The scoring mesh comprises interlacing filaments that extend from a mesh proximal end towards a mesh distal end, form distal filament loops at said mesh distal end, and then return to the mesh proximal end. At least a part of the interlacing filaments forms one or more permanent links with neighboring filaments between the mesh proximal end and the mesh distal end.
