FIELD: medicine.
SUBSTANCE: group of inventions relates to medical equipment, namely to surgical implant intended for placement around segment of gastrointestinal tract for narrowing of the latter, for example between abdominal part of oesophagus and stomach, method of its production, as well as to kit for surgical narrowing of gastrointestinal tract segment containing said implant. Inflatable adjustable gastric bandage intended for placement about gastrointestinal tract segment with purpose of its narrowing comprises hollow flexible bandage and flexible inflating tube. Hollow elastic flexible bandage has inner and outer wall forming inflatable sealed chamber with hole for inflation. Distal end of flexible inflating tube is connected with hole for inflation of bandage. Proximal end of flexible inflating tube is designed for connection with inflating means. Tube and bandage are fitted on corresponding distal end sections coupled by closing means to fix ring in closed position. Said ring is formed by bringing distal end and proximal end of bandage on principle of sliding assembly, in particular around gastrointestinal tract segment to be narrowed. Closing means of tube are made in form of at least one tooth. Closing means of bandage are composed of, at least one loop so that proximal end of tube intended to pass through, at least one loop of bandage is in fixed position of closing after, at least one tooth is fitted in, at least one said loop. When hollow flexible bandage is not used and tube and bandage do not engage with each other to form ring, bandage has previously formed curved part, which continues starting from proximal end part and continues with help of, in fact, rectilinear part to free distal end of bandage. Above, in fact, rectilinear part has length of 10–40 % of total length of hollow flexible bandage to facilitate engagement of proximal end of tube through at least one loop of bandage. Said, at least one loop is located on external wall of rectilinear part of hollow flexible bandage. Method of making said gastric bandage includes manufacturing of cast products by means of serial multiple molding in same form. Set for surgical narrowing of gastrointestinal tract segment contains said gastric bandage and inflated module provided with partition and intended for connection with proximal end of flexible tube to provide in-situ pressurization or removal of inflating liquid to inflate hollow bandage or discharge fluid from it.
EFFECT: inventions facilitate considerable progress in gastric implants for treating obesity; most significant advantage is assisting performing surgical operations, which increases safety level, and profit with respect to industrial production, taking into account economic factors and efficiency of production of cast assembly representing integral part of at least two materials or even three materials, for example using multiple molds for pressure casting.
