A stent for transluminal implantation comprised of a trunk and at least two joined cylindrical parts extending from the trunk, one part being capable of radially self-expanding, the other part being radially expandable only by means of a force applied thereto.
A stent for transluminal implantation comprised of a trunk and at least two joined cylindrical parts extending from the trunk, one part being capable of radially self-expanding, the other part being radially expandable only by means of an interior radial force wherein the one part comprises a proximal portion of the stent and wherein the one part is flared with respect to the rest of the stent when in the expanded condition.
An expandable bifurcated stent comprising
- a trunk,
- a first branch and
- a second branch,
- the first branch and the second branch each extending from the trunk, the stent comprising
- a self-expanding portion and
- a portion which requires the application of a force thereto to expand wherein
- the self-expanding portion comprises at least one of the trunk, the first branch and the second branch, and
- the portion which requires the application of a force thereto to expand comprises at least one of the trunk, the first branch and the second branch.
