摘要
Aspects of the invention provide a self-expanding stent device. The device comprises: an elongated body that defines a lumen within. The body has a first and a second terminus and a longitudinal axis located therebetween. The body comprises a first zone and a second zone along the longitudinal axis. When the device is in an expanded configuration the first zone has a first radial strength that is resistant to an external compressive force, and the second zone has a second radial strength that is resistant to an external compressive force. The radial strength of the first zone is greater than that of the second zone. The diameter of the body lumen proximal to the first terminus is greater than that of the lumen proximal to the second terminus.
