摘要：
FIELD: medicine.SUBSTANCE: spiral stent contains a spiral stent main component and polymeric material. The stent main component comprises the first side strip, the second side strip, the first end strip, the second end strip, the first hook and the second hook. The second side strip is connected to the first side strip to form a plurality of cells. Each of the first and second side strips has a wavy form. The first end of the first side strip tapers towards the second side strip. The first end of the second side strip tapers towards the first side strip. The first end strip comprises a set of spacers forming an extension of the first side strip. The first end of the first end strip is connected to the first end of the first side strip. The second end strip contains sets of spacers forming an extension of the second side strip. The first end of the second end strip is connected to the first end of the second side strip. The second end of the first end strip is connected to the first hook extending from the first side strip. The first hook extends from the first side strip and is alignable with the second end of the first end strip. The second hook extends from the second side strip and is alignable with the second end of the second end strip. Method of manufacture of the above spiral stent includes stages at which the second end of the first end strip is aligned with the first hook of the spiral main component of the stent, the second end of the first end strip is connected to the first hook, second end of the second end strip is aligned with the second hook, the second end of the second end strip is connected to the second hook, and specified polymeric material is applied. In accordance with an alternative version, the main component of the stent contains the first side strip and the second side strip, connected to each other by transverse spacers, as well as the first and the second hook. The first end of the first side strip tapers towards the second side strip in
