Abstract
A stent may include a flexible, elongate body having a curled proximal portion, a curled distal portion, and a main portion extending between the proximal and distal portions. The main and distal portions together may define a channel laterally open throughout at least a part of the channel's length and extending along the main and distal portions without extending along the proximal portion, whereby the channel's proximal end is disposed in the main portion. In addition, the proximal portion may be curled away from the channel.

A stent comprising a flexible, elongate body having a curled proximal portion, a curled distal portion, and a main portion extending between the proximal and distal portions, wherein:
- A) the main and distal portions together define a channel laterally open throughout at least a part of the channel's length and extending along the main and distal portions without extending along the proximal portion, whereby the channel's proximal end is disposed in the main portion;
- and
- B) the proximal portion is curled away from the channel.
A stent comprising a flexible, elongate body having a proximal portion, a distal portion, and a main portion extending between the proximal and distal portions, wherein:
- A) the body comprises a web and two flanges extending from opposite ends of the web, the web and flanges extending along the body, the flanges curving toward each other;
- B) the web and flanges together define a first channel and a second, smaller, channel, separate from the first channel;
- C) each channel is laterally open along at least a respective part of that channel's length;
- D) the first channel is laterally closed along at least a part of its length;
