An improved balloon-tipped catheter includes means for convectively heating the inflation medium within the balloon during dilation. In the preferred embodiment, the convective heat is provided by a radiant heating block which is attached to a laser light source through an optical waveguide extending the length of the catheter. The convectively heated balloon promotes restoration and healing of the arterial wall in the region of stenosis, which region normally suffers from cracking, tearing, and stretching. It has been found that damage to the arterial wall can sometimes result in abrupt closure of the artery and frequent restenosis in the same region.
A catheter comprising: a flexible tube having distal and proximal ends, the distal end being insertable into a blood vessel; an inflatable balloon secured to the tube near its distal end; means for inflating the balloon to provide a volume of inflation medium therein; and means for convectively heat
A catheter comprising: a flexible tube having distal and proximal ends, the distal end being insertable into a blood vessel; an inflatable balloon secured to the tube near its distal end; means for inflating the balloon to provide a volume of inflation medium therein; and means for convectively heating the inflation medium in the balloon to a temperature in the range from about 40°C. to 80°C. above normal body temperature.
