Abstract An improved insufflating device particular adapted for use in intrauterine surgical procedures, and similar applications. The device is characterized in the provision of a first hollow shaft having an open distal end through which the barrel of an endoscopic or cystoscopic device is passed. A first inflatable balloon surrounds the shaft and serves to distend the lower portion of the uterus. A second balloon is mounted upon the distal end of a second hollow shaft fixed to the inner surface of said first shaft, and serves to distend the upper portion of the uterus, leaving a clear medially disposed circular area affording access to the lumen of the fallopian tubes for cauterization or other surgical procedure.
An improved uterine insufflating device adapted to be positioned substantially entirely within the uterus of a patient, comprising: a first relatively rigid hollow shaft, a first inflatable balloon mounted on an outer surface of said first shaft between proximal and distal ends thereof; a second hollow shaft of diameter substantially less than the bore of said first shaft, sufficient to enable the introduction of a surgical instrument between said first and second shafts, and extending therethrough to project distally from the distal end of said first shaft, and a second inflatable balloon mounted on a distal end of said second shaft; whereby when said device is inserted within a uterus, and both balloons are inflated to expand the same, a clear generally annular interstice is formed between the balloons accessible from the distal end of said first shaft within which a surgical procedure may be performed.
