Abstract
The present invention is directed to vascular implants and methods for fabricating the same. The implantable devices include but are not limited to stents, grafts and stent grafts. In many embodiments, the devices include one or more side branch lumens interconnected with the main lumen.
Claims29
A stent device for implantation within a tubular organ, the stent device comprising:
- a first ring and a second ring made of a first material;
- a third ring made of a second material different from the first material;
- a tubular body having a main lumen, where the tubular body comprises the first, second and third rings, where the third ring is between the first and second rings such that application of a tensile force on the tubular body causes the tubular body to reduce in a diameter as the length of the tubular body extends;
- and
- a first side branch extending from the tubular body and having a first side branch lumen wherein the first side branch lumen is adjustable relative to the main lumen.

A stent device for implantation within a tubular organ, the stent device comprising:
- first rings comprising a first material, each first ring separately formed in an undulating shape having apices;
- second rings comprising a second material different from the first material, each second ring having apices,
- where the first and second rings interconnect to form a tubular body having a main lumen, where each first ring is spaced from an adjacent first ring and where each second ring is interlaced with each adjacent first ring such that application of a tensile force on the tubular body causes the tubular body to reduce in a diameter as the length of the tubular body extends;
- and
- a first side branch extending from the tubular body and having a first side branch lumen wherein the first side branch lumen is adjustable relative to the main lumen.
2 more elements
A stent device for implantation within a tubular organ, the stent device comprising:
- a plurality of non-polymeric rings, each non-polymeric ring separately formed in an convoluting shape having a plurality of apices;
- a plurality of polymeric rings, each polymeric ring formed in an undulating shape having a plurality of apices;
- where the plurality of non-polymeric rings and polymeric rings interconnect to form a tubular body having a main lumen, where each non-polymeric ring is spaced from an adjacent non-polymeric ring and where each polymeric ring is interlaced with each adjacent non-polymeric ring such that application of a tensile force on the tubular body causes the tubular body to reduce in a diameter as the length of the tubular body extends;
- and
- a first side branch extending from the tubular body and having a first side branch lumen wherein the first side branch lumen is adjustable relative to the main lumen.
