Abstract (en)

[origin: WO9966979A1] The present invention relates generally to a radioisotope delivery device (10) comprising a radioisotope housing (12) containing a series of radioisotope sources (14), and inflatable balloons (16) being located at opposing ends of the housing (12). The delivery device (10) is slidably received over a conventional guidewire (22). The inflatable balloons (16) are in this example located at opposing ends of the radioisotope housing (12) and consist of four generally elliptical-shaped balloons (16A to 16D). The balloons (16) are provided so as to radially space the radioisotope sources (14) a predetermined and fixed distance from a wall of an artery or blood vessel. The balloons (16) both in an inflated and deflated configuration provide a passage designated generally as (24) between the radioisotope housing (12) and the arterial or blood vessel wall for the flow of blood through the artery or blood vessel.
