Abstract: A system for treating a bifurcation includes first and second delivery catheters, each having an expandable member. A stent having a side hole is disposed on the second delivery catheter. A portion of the first delivery catheter is disposed under a portion of the stent. The first delivery catheter is slidable relative to the second delivery catheter, and the first delivery catheter passes through the side hole. Expansion of the first expandable member expands a proximal portion of the stent in a main branch vessel, and expansion of the second expandable member expands a distal portion of the stent in a side branch vessel.

Abstract: A system for treating a bifurcated vessel comprises a first delivery catheter and a second delivery catheter. The first delivery catheter carries a first stent comprised of a proximal stent and a distal stent. The first delivery catheter also has a first elongate shaft, a proximal expandable member with the proximal stent disposed thereover, and a distal expandable member with the distal stent disposed thereover. The proximal and distal expandable members are independently expandable of one another. The second delivery catheter carries a second stent. The second delivery catheter also has a second elongate shaft, and a second expandable member with the second stent disposed thereover. The second expandable member is independently expandable of the proximal and the distal expandable members.

Abstract: An elongate shaft management device has an upper plate and a lower plate. The lower plate has at least one groove that is sized to receive the elongate shaft. The at least one groove in the lower plate cooperates with the upper plate to capture the elongate shaft and prevent movement of the elongate shaft. The upper plate is releasably coupled to the lower plate to provide access to the elongate shaft and allow it to be manipulated.

Abstract: Methods for crimping a stent on an expandable member of a delivery catheter, and devices and methods for treating a bifurcation are disclosed. A method for crimping includes positioning a stent having a first portion and a second portion over the expandable member, and non-uniformly crimping the stent to the expandable member. The method can include routing an elongate shaft under the second portion of the stent and through the side hole so as to be routed external to the first portion. The stent second portion can be crimped so that the elongate shaft can be slidably disposed relative to the stent second portion prior to deployment of the stent.

Abstract: A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.

Abstract: A system for treating a bifurcated vessel that includes a first delivery catheter and a second delivery catheter. The first delivery catheter carries a proximal first stent and a distal second stent. The first delivery catheter also has a first elongate shaft, a proximal first expandable member with the proximal first stent disposed thereover, and a distal second expandable member with the distal second stent disposed thereover. The proximal first expandable member and distal second expandable member are independently expandable of one another. The second delivery catheter carries a third stent. The second delivery catheter also has a second elongate shaft, and a third expandable member with the third stent disposed thereover. The third expandable member is independently expandable of the proximal first expandable member and the distal second expandable member.

Abstract: A system for treating a bifurcation includes first and second delivery catheters. The first catheter has a first shaft, a first expandable member adjacent the distal end of the first shaft, an auxiliary expandable member disposed under the first expandable member, and a first radially expandable stent disposed over both the first expandable member and the auxiliary expandable member. The second delivery catheter has a second shaft, and a second expandable member adjacent the distal end of the second shaft. A portion of the second catheter is disposed under a portion of the first stent, and a portion of the second delivery catheter passes through a side hole in the first stent. The first stent is crimped over the first and second catheters such that the first stent remains attached to the first and the second catheters during advancement of the catheters through a blood vessel.
