The invention relates to an intragastric
balloon for the treatment of persons having severe or
morbid obesity problems, wherein the number of elements in the already known systems is reduced, and provides a material savings in the manufacture thereof. The intragastric
balloon assembly comprises a
balloon connected to a
catheter to inflate the same, and includes a means for fixing the same to a patient body, consisting in a plain fixing plate with a sole orifice through which said inflation
catheter is passed, to be fixed subcutaneously in the abdominal region of said patient; and in a preferred embodiment, an additional fastening element is provided allowing firmly subject said inflation
catheter to said fixing plate, and consisting in a semi-rigid
washer or ring made of
silicon, which is fastened to the catheter and fixing plate by means of a suitable
adhesive; thus maintaining said catheter with a pulling suitable for the balloon to be pasted perfectly but without pressure at all, on the
stomach wall. Said
assembly also comprises a multi-puncture valve to which said inflation catheter is connected to inflate said balloon, which in turn can be arranged on the fixing plate, whereby an alternative element to fasten the catheter and, therefore, the balloon
assembly is obtained.
