Abstract:
1. A method for treating a defect in bifurcated vasculature having a common blood vessel and at least first and second branch blood vessels, said method comprising the steps of: A) providing or obtaining a system that comprises; advancing the catheter over a guidewire which extends through the guidewire lumen of the elongate member, while maintaining the elongate member in the distal position to maintain the proximal and distal expandable areas in their elongated radially collapsed configurations; B) with the elongate member advanced to a position where it causes both the proximal and distal expandable areas to be in their elongated and radially collapsed configurations, advancing the catheter over the guidewire which extends through the guidewire lumen of the elongate member to a position where the proximal expandable area is in the lumen of the common blood vessel and the distal expandable area is in the lumen of the first branch blood vessel, with the second branch blood vessel emanating from a location between the proximal and distal expandable areas; C) retracting the elongate member to the proximal position a position whereby it allows both the proximal and distal expandable areas to assume non-elongated radially expanded configurations such that the proximal expandable area contacts the common blood vessel wall and the distal expandable area contacts the first branch blood vessel wall; D) advancing a treatment device through the elongate member receiving lumen, out of the treatment device outlet opening and into the lumen of the second branch blood vessel; and E) using the treatment device to perform or facilitate performance of a treatment of a defect in the second branch blood vessel.
