Abstract
Apparatus for thermal coagulation having an improved circulation assembly and heating assembly. The apparatus includes a balloon catheter secured to and in fluid communication with a handle for inserting the apparatus into a human uterus. A distensible bladder is secured to the distal end of the catheter and encloses a heating assembly having a tubular core configured with a spiral groove which retains a heating filament. An impeller having at least two blades is positioned distal of the heating assembly and includes a cable having a distal end secured to the impeller. The impeller cable is partially disposed in the handle, in the elongate tubular member and in the core of the heating element, such that axial rotation of said cable rotates the blades of said impeller. During use of the apparatus, the distensible bladder is inflated with a fluid to a desired pressure and rotation of the impeller blades is initiated. The inflation fluid within the distensible bladder is heated to a desired temperature, which is maintained for a desired time interval. The inflation fluid within the distensible bladder is allowed to cool and rotation of the impeller blades is terminated. Thereafter, the inflation fluid is removed from the balloon catheter to deflate the distensible bladder.
