Abstract:
A system for anchoring an angioplasty catheter to a stenosis in the vasculature of a patient which comprises:an elongated inflatable balloon having a surface and defining a longitudinal axis, said balloon being mounted on said catheter for selective movement between a deflated configuration wherein said surface of said balloon is collapsed on said axis, and an inflated configuration wherein said surface is radially distanced from said axis; at least one elongated blade mounted on said surface of said balloon substantially parallel to said axis of said balloon; at least one azimuthally oriented cross-blade grip conformed with said blade, said grip being oriented to protrude in a substantially radial direction from said axis; and a means for inflating said balloon into said inflated configuration to embed said blade and said grip into said stenosis to anchor said balloon thereto by respectively preventing azimuthal and axial movements of said balloon relative to said stenosis.
