BACKGROUND OF THE INVENTION [0001]1. Field of the Invention [0002]The present invention relates to a fistulectomy method of forming a fistula between a first duct and a second duct, an ultrasonic endoscope, a catheter with balloons arranged in a fistula, a magnetic retaining device which retains a magnet which is magnetically attached to the other magnet through a wall surface of a biomedical tissue, and a magnet assembly which is magnetically attached to the other magnet through a wall surface of a biomedical tissue. [0003]2. Description of the Related Art [0004]U.S. Pat. No. 5,690,656 discloses "Method and apparatus for creating abdominal visceral anastomoses". [0005]Yamanouchi et al. (Journal of Nippon Medical School 2002; 69(5)) discloses an intestine-intestinal system magnetic compression anastomosis which anastomoses, e.g., an oral-side intestine with an analis intestine by using a pair of magnets. When the pair of magnets are retained and attached to each other with wall surfaces of intestines sandwiched therebetween, the two intestinal wall layers sandwiched between the magnets are gradually led to avascular necrosis. At this time, the intestinal walls which are in contact with each other adhere to each other, and a hole is formed. BRIEF SUMMARY OF THE INVENTION [0006]According to one aspect of the present invention, there is provided a fistulectomy method of forming a fistula between a first duct and a second duct, including: [0007]sticking a puncture needle into the second duct from the inside of the first duct through a wall surface of the first duct and a wall surface of the second duct; [0008]arranging the puncture needle at a position of a central axis and sticking a coil needle around the puncture needle from the first duct toward the second duct to couple the first duct with the second duct; [0009]maintaining the coil needle in a state where the first duct communicates with the second duct; and [0010]forming the fistula on an inner side of the coil needle. [0011]According to another aspect of the present invention, there is provided an ultrasonic endoscope including; an elongated insertion section having a distal end and a proximal end; and an operation section provided at the proximal end of the insertion section. The insertion section has at the distal end a distal end hard portion having an ultrasonic transducer, a forceps opening portion and an object lens in alignment. [0012]Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.
