Apparatus for treating a bifurcated region of a conduit
First Claim
1. An apparatus comprising:
- a first annular element having at least one lumen longitudinally disposed therein;
at least two secondary annular elements each having at least one guide wire lumen in communication with the at least one lumen of the first annular element, the at least two secondary annular elements extending from the distal end of the first annular element;
at least two expansion members mounted at the distal end of the at least two secondary annular elements, wherein each expansion member is in fluid communication with at least one inflation source;
at least two devices wherein one of the at least two expansion members passes through the length of a first device and a second of the at least two expansion members passes through at least a proximal portion of the first device and exits at a location between the proximal and a distal end of the first device;
wherein a second of the at least two devices is mounted on the second of the at least two expansion members such that the expansion member passes through the length of the second device; and
wherein the expansion members each have a distal tip and a connection there between that releasably holds the tips together.

Abstract
A system for treating a diseased body conduit bifurcation that is readily deliverable into a region of a body conduit having typically asymmetric anatomy, such as a vessel bifurcation is provided. The system comprises a delivery device such as a catheter having a shaft with varying torsional properties along its length and a delivery apparatus mounted at its distal end. A distal end of the device can be inserted into the main branch and at least one side branch of a vessel bifurcation. The distal end includes at least two expansion members having expandable scaffolds or prostheses mounted thereon. One scaffold is configured such that one expansion member extends through the length of the scaffold while the other expansion member extends through the side-structure of the scaffold. A second scaffold is mounted on the expansion member extending through the side-structure of the first scaffold.
