Patent ID: 8900207

Claim:
A percutaneous procedure useful for treating vasculature lesions having plaque or occlusion comprising the steps of: (a) locating within a patient subject a lesion having plaque or occlusion that is affecting the blood flow of the vasculature, such lesion having a proximal main branch area, a distal main branch area, a side branch area, and a carina; (b) positioning into the distal main branch area a first guide wire having a distal tip and a proximal tip, until the distal tip of the first guide wire extends through the distal main branch area beyond the bifurcation lesion; (c) positioning into the side branch area a second guide wire having a distal tip and a proximal tip, until the distal tip of the second guide wire extends through the side branch area beyond the bifurcation lesion; (d) advancing simultaneously along the first guide wire and the second guide wire a plural tip catheter having a proximal end and a distal end, a proximal connector at the proximal end, a tapered expandable member at the distal end, a first guide wire lumen beginning at the distal end and extending at least a portion of the longitudinal length of the catheter, a second guide wire lumen beginning at the distal end and extending at least a portion of the longitudinal length of the catheter, and a pressurizing lumen extending substantially the entire length of the catheter; (e) advancing the plural tip catheter to the carina; (f) expanding the tapered expandable member of the plural tip catheter in the proximal main branch area to a predetermined diameter to reconfigure the plaque or occlusion; (g) deflating the tapered expandable member; (h) removing the plural tip catheter, leaving in position the first guide wire and the second guide wire; (i) advancing along the first guide wire a single tip catheter having a proximal end and a distal end, a proximal connector at the proximal end, an expandable member at the distal end, a single guide wire lumen beginning at the distal end and extending at least a portion of the longitudinal length of the catheter, and a pressurizing lumen extending substantially the entire length of the catheter; (j) advancing the single tip catheter to a location distal to the carina; (k) expanding the expandable member of the single tip catheter to a predetermined diameter to reconfigure the plaque or occlusion; (l) deflating the expandable member of the single tip catheter; (m) removing the single tip catheter, leaving in position the first guide wire and the second guide wire; (n) repeating the advancing of the single tip catheter along the first guide wire or the second guide wire to reconfigure the plaque or occlusion as needed; and (o) removing the first guide wire and the second guide wire at the conclusion of the procedure.
