FIELD: medical engineering. SUBSTANCE: device has the first tubular member having longitudinal canal formed from a sheet having the first side, the second side, the third side, the fourth side, the fifth side, the sixth side, the seventh side and the eighth side. The second side is connected to the eighth side, the fourth one to the sixth one and the third one and the seventh one restrict branching aperture located between the first and the fifth side. Method for producing stent involves a) producing sheet for making the first tubular member having longitudinal canal having the first side, the second side, the third side, the fourth side, the fifth side, the sixth side, the seventh side and the eighth side; b) connecting the second side to the eighth one, the fourth one to the sixth one so that the third one and the seventh one restrict branching aperture from the mentioned canal located between the first and the fifth side. The stent has sheet having longitudinal axis, the first part and the second part. The first part has proximal end, distal end, the first lateral side and the second lateral side. Lateral sides of the first part are essentially parallel to the longitudinal axis and separated with the first distance. The second part has proximal end, distal end, the first lateral side and the second lateral side. Lateral sides of the second part are essentially parallel to the longitudinal axis and separated with the second distance that is less than the first distance. The proximal end of the second part is connected to the distal end of the first part. The first lateral side of the first part is connected to the first lateral side of the first part and the first lateral side of the second part is connected to the second lateral side of the second part to build the first tubular member having a through longitudinal canal. A portion of proximal end of the first part and a portion of the distal end of the second part restrict aperture of the lateral branch. Method for producing branching stent involves a) producing the first extendable tubular member having proximal end, distal end and a through longitudinal canal so that the first tubular member has branching aperture positioned between the proximal end and the distal end; the branching aperture is connected to longitudinal canal and has required size to allow the second extendable tubular member being received and fixed; b) delivering the first extendable tubular member to branching reservoir having the first cavity and the second cavity so that the first extendable tubular member is introduced into the first cavity and the branching aperture communicates with the second cavity; c) dilating the branching aperture by a value enough for additional branching aperture connection to the second cavity; d) dilating the first extendable tubular member by a value enough for fixing the first extendable tubular member in the first cavity; e) delivering the second extendable tubular member having proximal end, distal end and a through longitudinal canal so that the distal end of the second extendable tubular member is introduced into the second cavity and the proximal end of the second extendable tubular member is to be introduced into the first tubular member branching aperture, the longitudinal canal of the second extendable tubular member is in under liquid exchange conditions with the longitudinal canal of the first extendable tubular member; and f) dilating the second extendable tubular member by a value enough for fixing the second extendable tubular member in the second cavity and in the branching aperture. EFFECT: improved production process. 16 cl, 34 dwg
