Abstract:
1. A stent comprising: an elastic tubular body having a first end and an opposite second end and an outside diameter, the body comprising a braiding of a first group of spaced apart helically wound first elastic strands and a second group of spaced apart helically wound second elastic strands such that the outside diameter of the body increases when the first end of the body is moved towards the second end of the body, and such that the outside diameter of the body decreases when the first end of the body moves away from the second end of the body; and an adjustment mechanism for the moving the first end of the body toward or away from the second end of the body, the adjustment mechanism including a bracket, a tension adjustor, and a tensioning wire attached to the bracket and the tension adjustor such that the bracket and the tension adjustor are in spaced apart relationship, the bracket being attached to at least one of the first elastic strands and the second elastic strands, the tension adjustor being attached to at least one of the first elastic strands and the second elastic strands, wherein a distance between the bracket and the tension adjustor can be varied to move the first end of the body towards the second end of the body or to move the first end of the body away from the second end of the body, and wherein the tension adjustor comprises a housing having a hole with internal threads that mate with an external threaded section of the tensioning wire, and wherein the distance between the bracket and the tension adjustor can be varied by rotating the tensioning wire with respect to the hole.
