Abstract
A stent which may be emplaced into the lumen of the body. The stent has an expandable first section with a first diameter and an expanded second diameter larger than its first diameter. There is also a second section connected to the first section, the second section contains a third diameter and an expanded fourth diameter which is larger than the third diameter. Finally, the second diameter is different from the fourth diameter. Thus, the device may be emplaced between lumens of different sizes. Ideally, this stent can be placed at the junction at the aorta and the iliac arteries, where the size of the lumens are typically different. in use, therefore, the device provides the surgeon with a useful tool to holding open junctions of various sized lumens.
Claims (5)
1. A stent for emplacement into a body lumen comprising:
a first portion having a cylindrical shape and a longitudinal axis, containing an array of slots arranged around the diameter of said cylinder, said slots having a relaxed dimension and an enlarged dimension around the circumference of said cylinder, whereby in said enlarged dimension, said cylindrical shape increases in diameter, and said slots having a predetermined length when said slots are in said relaxed dimension; and a second portion connected to said first portion, said second portion having a cylindrical shape and a longitudinal axis, containing an array of slots arranged around the diameter of said cylinder, said slots having a relaxed dimension and an enlarged dimension around the circumference of said cylinder, whereby in said enlarged dimension, said cylindrical shape increases in diameter, and said slots having a predetermined length wherein said slots are in said relaxed dimension; and whereby said first portion and said second portion are created from a single thin-walled metallic tube and wherein said first portion slot lengths are greater than said second portion slot lengths.
a first portion having a cylindrical shape and a longitudinal axis, containing an array of slots arranged around the diameter of said cylinder, said slots having a relaxed dimension and an enlarged dimension around the circumference of said cylinder, whereby in said enlarged dimension, said cylindrical shape increases in diameter, and said slots having a predetermined length when said slots are in said relaxed dimension; and a second portion connected to said first portion, said second portion having a cylindrical shape and a longitudinal axis, containing an array of slots arranged around the diameter of said cylinder, said slots having a relaxed dimension and an enlarged dimension around the circumference of said cylinder, whereby in said enlarged dimension, said cylindrical shape increases in diameter, and said slots having a predetermined length wherein said slots are in said relaxed dimension; and whereby said first portion and said second portion are created from a single thin-walled metallic tube and wherein said first portion slot lengths are greater than said second portion slot lengths.
2. The stent of claim 1 wherein said first portion is expandable to a first diameter and wherein said second portion is expandable to a second diameter and said first and second diameters having different sizes.
3. The stent of claim 2 wherein each of said first and second sections are comprised of expandable cells, each of said cells forming a cross-hatched pattern within said expandable sections.
4. The stent of claim 3 wherein said cross-hatched pattern forms diamond-shaped cells when each of said sections are expanded.
5. The stent of claim 2 wherein said stent is made from an expandable spring metal.
