INTRALUMINAL STENTS FOR TREATING BENIGN PROSTATIC HYPERPLASIA

A device for maintaining patency of a prostatic urethra includes a stent having a passageway between proximal and distal ends. The device includes longitudinal and angled struts and nodes, each longitudinal strut coupled to at least one angled strut at a corresponding node, the struts and nodes coupled to each other to form a plurality of cells, circumferentially adjacent cells forming stent regions. The stent is configured to expand from a compressed configuration to an expanded configuration within a bodily lumen. The stent includes a collapsibility gradient along its length such that it provides a nose region radial force at a nose region, a body region radial force at a body region, and a tail region radial force at a tail region, wherein the nose region radial force is less than the tail region radial force, and the tail region radial force is less than the body region radial force.
