Abstract: A guiding sheath system includes a first sheath having a proximal end and a distal end, an extension member connected to the distal end of the first sheath, the extension member terminating in a distal end, a second sheath extending through the first sheath, the second sheath having a proximal end and a distal end, and a cap connected to the distal end of the extension member and the distal end of the second sheath. Upon advancing the second sheath through the first sheath, the cap restrains the distal end of the second sheath and the cap deflects relative to the first sheath thereby causing a portion of the second sheath protruding from the first sheath to bend into a curve with the distal end of the second sheath at a vector different from a vector of the first sheath.

Abstract: An endograft is provided for a blood vessel having a branch extending from said blood vessel, including a body having a wall defining a lumen and an exterior surface. The endograft body includes a first portion defining or being made to define a non-circular cross-sectional dimension, and a second portion defining a circular cross-sectional dimension. Modular systems including the endograft and methods for creating endografts according to the disclosure are described also.

Abstract: A method of anatomic classification of blood vessel anatomy in aneurysms includes the steps of accessing an image of a blood vessel, analyzing the image to identify a point of divergence of the blood vessel and one or more additional points of reference of the blood vessel. One or more distances are then measured between the point of divergence of the blood vessel and at least one of the one or more additional points of reference. The aneurysm is then classified based upon the measured distances. A method of treatment of an aneurysm in a blood vessel further includes implanting one or more devices within the blood vessel for treatment of the aneurysm.

Abstract: A segmented endograft includes at least one positioning segment and at least one main body segment which are separately deployable. The at least one positioning segment and at least one main body segment may be connected one to another. For example, the at least one positioning segment and at least one main body segment may be connected along a portion of a circumference thereof, but unconnected along a remainder of the circumference thereof. The at least one positioning segment overlaps a portion of the at least one main body segment. Deployment systems may include the segmented endograft and the segmented endograft may be deployed according to various methods.

Abstract: A segmented endograft includes at least one positioning segment and at least one main body segment which are separately deployable. The at least one positioning segment and at least one main body segment may be connected one to another. In an embodiment, the at least one positioning segment and at least one main body segment are connected along a portion of a circumference thereof, but unconnected along a remainder of the circumference thereof. The at least one positioning segment overlaps a portion of the at least one main body segment. Deployment systems including the segmented endograft and methods for deploying a segmented endograft are described.
