1. A stent, the stent comprising:
an elongated tubular member having a first end, a second end and an intermediate region disposed therebetween, the elongated tubular member having at least one aperture at the first end; and
a biodegradable tie having a first discrete opening at a first end, a second discrete opening at a second end, the first and second discrete openings spaced apart by a middle region defining a first portion extending between the first discrete opening and the second discrete opening and a second portion extending between the first discrete opening and the second discrete opening, the first and second portions secured to one another along the middle region;
wherein the first end of the biodegradable tie is attached to the aperture in the elongated tubular member and the second end of the biodegradable tie is configured to extend beyond the first end of the elongated tubular member to be secured to tissue at a location beyond the first end of the elongated tubular member with a securing mechanism, wherein in the absence of the securing mechanism the second end of the biodegradable tie is configured to hang into a lumen of the elongated tubular member.
