摘要：
1. A stent, comprising: a frame having distal and proximal ends and delineating a central cavity along the longitudinal axis, the frame having an insertion configuration with a reduced profile and a deployed configuration with an enlarged profile greater than the insertion profile, the frame including a certain number of spaced undulating wavy circumferential links and a screw member extending along a helical path around the longitudinal axis in the axial direction and arranged between the directly attached to the circumference links, wherein the screw member wavy outlines a number of open cells, and the circumferential element outlines a number of closed yacheek.2. The stent of claim 1, wherein the wavy circumferential link includes one undulating helical coil connected with a wavy circumferential koltsom.3. The stent of claim 2, wherein the undulating helical coil of each circumferential unit is directly attached to the helical coil elementa.4. The stent of claim 2, wherein the circumferential member includes a number of connectors closed cells extending substantially parallel to the longitudinal axis, which form a connection between the interior vertices undulating helical coil and the adjacent wavy circumferential ring circumferentially zvene.5. The stent of claim 4, wherein the closed cells connectors izmenyayutsya.6 length. The stent of claim 5, wherein the connector lengths of closed cells increases uniformly along the circumferential direction stenta.7. The stent of claim 6, wherein the circumferential ring at the distal and proximal ends of the stent outline plane orthogonal to the longitudinal osi.8. The stent of claim 4, wherein a connector for
