Rail stent and methods of use
First Claim
1. A stent for positioning within a body lumen comprising:
- a radially expandable body having a first end, a second end and a longitudinal axis extending between the first and second ends, the expandable body transitionable between an unexpanded state and an expanded state; and
at least one loop having an opening extending from the first end, wherein alignment of the opening of the at least one loop with the longitudinal axis transitions at least the first end toward the unexpanded state.

Abstract
Devices, systems and methods are provided for stenting body lumens. In particular, stents are provided which are advanceable directly over a guidewire and expandable within a target location of a body lumen by retraction of the guidewire and/or by releasing constraining element(s) disposed around at least a portion of the stent. Typically the constraining element(s) have the form of one or more bands or layers of material which hold the stent in an unexpanded configuration. These stent designs allow delivery to a body lumen without the need for a number of additional devices which are typically used in the delivery of conventional stents, thereby reducing the profile of the stent during delivery, increasing the flexibility of the stent during delivery to allow passage through more tortuous pathways, and allowing the delivery of branched or otherwise connected stents to body lumens, such as branched lumens.

16. A method of positioning a stent, wherein the stent comprises an radially expandable body having a first end, a second end and a longitudinal axis extending between the first and second ends, and at least one loop extending from the first end, the method comprising:
mounting the stent on a first guidewire, wherein mounting comprises positioning a portion of the first guidewire within the at least one loop along the longitudinal axis causing at least the first end to transition toward the unexpanded state. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
