ABSTRACT:
A balloon anchor for use with an endoscopically inserting ultrasound probe having an ultrasound transducer element accommodated in an ultrasound scanner head at the fore distal end of a flexible cord to be placed in an endoscopic biopsy channel. The balloon anchor includes an anchor tube which is adapted to be fitted in the endoscopic biopsy channel in such a way that it is partly projected from fore distal end of the endoscopic biopsy channel. Connected to the projected fore end of the anchor tube is a balloon support member of a larger diameter as compared with the endoscopic biopsy channel. A passage of a large diameter is formed axially through the anchor tube and through the balloon support member. A balloon stopper portion is provided on the outer periphery of the balloon support member to anchor a resilient ring of a balloon therein.
