Branch vessel stent and graft
First Claim
Patent Images
1. A frame for an anatomical vessel with an inner surface defining an inner circumference and at least one connecting branch vessel with an inner surface defining an inner circumference, comprising:
- a first open-cylinder member with an outer surface defining a circumferential arc length, first and second opposing end portions, and a connection location, wherein said circumferential arc length is at most equal to the anatomical vessel inner circumference, wherein said first open-cylinder member is adapted for placement within the lumen of the anatomical vessel with a substantial portion of said first open-cylinder member outer surface contacting the anatomical vessel inner surface, wherein said connection location is nearer to said first opposing end than said second opposing end; and
a first cylindrical connecting member connected to said first open-cylinder member at said connection location, said first cylindrical connecting member adapted for placement within the lumen of the first connecting branch vessel with a substantial portion of said first cylindrical connecting member outer surface contacting at least one branch vessel inner surface.

7. A stent for the anatomical vessels surrounding a junction between a first anatomical vessel and at least a second anatomical vessel, comprising:
a first open-cylinder stent portion with an outer surface, wherein said first open-cylinder stent portion is adapted for placement within the lumen of the first anatomical vessel with said outer surface substantially contiguous with the first anatomical vessel inner surface. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for grafting a region between a reference blood vessel and at least one branching blood vessel, comprising:
-
collapsing a first open-cylinder stent portion adapted for placement within the lumen of the reference blood vessel;
placing the collapsed first open-cylinder stent portion within the lumen of at least one of the reference blood vessel and a first branching blood vessel; and
expanding the first open-cylinder stent portion, wherein said expanding results in a substantial portion of the first open-cylinder stent portion contacting the reference blood vessel inner surface. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
