Abstract From the Canadian patent

A balloon catheter suitable for use in the recanalisation of stenoses in bodily canals, in particular coronary blood vessels and peripheral arterial vessels is provided with a, microwave antenna (9) arranged on the inside of said balloon said antenna being connected to a microwave generator by means of a coaxial cable (8). The irradiation by microwaves of a microwave-absorbing dilation liquid and/or a metallic balloon skin coating causes said balloon catheter to be heated which in turn allows the vessel wall to be subjected to a thermal posttreatment required to prevent the reoccurrence of stenosis.
