Abstract

An endoluminal stent and associated methods for placing the endoluminal stent in a lumen of a trachea of a patient. The stent includes an elongate framework having a first open end, a second open end opposite the first open end, and a lumen extending from the first open end to the second open end. The elongate framework includes a first edge extending from the first open end to the second open end, a second edge extending from the first open end to the second open end, and an opening between the first edge and the second edge extending from the first open end to the second open end such that the stent has a C-shaped cross-section. The stent may be implanted in a trachea with the opening positioned along a posterior wall of the trachea adjacent the trachealis muscle.

First claim

What is claimed is:

1. An endoluminal stent having a first open end and a second open end, comprising:
an elongate framework, wherein the elongate framework comprises interconnected struts and interstices formed therebetween; and
a covering layer covering at least a portion of the elongate framework;
the elongate framework having a first end at the first open end of the endoluminal stent, a second end at the second open end of the endoluminal stent, and a lumen extending from the first open end of the endoluminal stent to the second open end of the endoluminal stent;
the elongate framework including a first edge extending from the first open end of the endoluminal stent to the second open end of the endoluminal stent, a second edge extending from the first open end of the endoluminal stent to the second open end of the endoluminal stent, and an opening between the first edge and the second edge, the opening extending continuously from the first open end of the endoluminal stent to the second open end of the endoluminal stent;
wherein the covering layer includes a first portion covering the interconnected struts and interstices of the elongate framework, and the covering layer includes a second portion extending across the opening between the first and second edges of the elongate framework; and
wherein the first portion has a first thickness and the second portion has a second thickness different than the first thickness.

2. The endoluminal stent of claim 1 , wherein the second thickness is greater than the first thickness.

3. The endoluminal stent of 1 , wherein the second thickness is less than the first thickness.

4. The endoluminal stent of claim 1 , wherein the covering layer extending across the opening is generally planar.

5. The endoluminal stent of claim 1 , wherein the endoluminal stent is configured to be implanted in a trachea, and the covering layer extending across the opening is configured to deflect into the lumen of the elongate framework with a flexure of a trachealis muscle of the trachea.
