Abstract
An apparatus and method is provided for stenting bifurcated vessels. A proximal angled stent is configured for implanting in a side-branch vessel wherein the proximal angled stent has an angulated portion that corresponds to the angle formed by the intersection of the side-branch vessel and the main vessel so that all portions of the side-branch vessel at the bifurcation are covered by the proximal angled stent. A main-vessel stent is provided for implanting in the main vessel, wherein the main-vessel stent has an aperture or stent cell that aligns with the opening to the side-branch vessel to permit unobstructed blood flow between the main vessel and the side-branch vessel. Side-branch and main-vessel catheter assemblies are advanced over a pair of guide wires for delivering, appropriately orienting, and implanting the proximal angled stent and the apertured stent.

33. A catheter system for deploying a Y-shaped stent in a bifurcation, comprising:
-
a catheter having a proximal end and an expandable branched distal end with a first branch and a second branch, said distal end having a first configuration wherein said branches converge and a second configuration wherein said branches diverge; and
a first guide wire for converting said distal end from said first configuration to said second configuration. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)

41. A stent delivery system, comprising:
-
a catheter having an expandable branched distal end with a first branch and a second branch, wherein said two branches are biased so as to diverge from one another; and
a first guide wire routed through said catheter so as to overcome said bias and releasably maintain said distal ends in a converging configuration. - View Dependent Claims (42, 43, 44, 45, 46, 47)
