Abstract: The balloon is fixed to a catheter close to its distal portion; the catheter has two ducts passing through within in; one duct can be used for a guide wire, while the other is used to pump air in or out; after passing through the catheter, the air emerges from a hole in the wall of the distal portion of the catheter, within the balloon; the distal portion of the catheter emerging from the balloon is rigid and slightly curved with respect to the axis of the catheter so that, when used, the distal portion—fitted with a sphere at the very tip—is curved upwards; the sides of the inflatable balloon are of varying thickness so that, when inflated, it takes on the form of a mattress; its inflation enables the detachment without trauma of two layers of tissue.

Abstract: The invention is of valid use in the field of the treatment of anal sphincter pathologies, especially for the treatment of fissures and sphincter hypertonia. The procteurynter in question consists of a bag (1) made of plastic material and a sheath (2) that is internally crossed by two tubes: one tube (3) for the flow of water or air and a second tube (4) for the eventual introduction of an ultrasonoscope. Once the bag (1) is filled with water or air through the holes (2.6) made in the wall (2.5) of the sheath (2), it takes on an hourglass shape: two cones with a central neck or constriction.The distal part of the sheath (2) has a plug (2.3) inside it to completely occlude the internal lumen whereas the inner portion of proximal part of the sheath (2) has a disk (2.4) whose central hole is crossed by a tube (4); one of the ends of tube (3) is lodged in a second hole that lies acentrically on the said disk (2.4).
