Abstract:
1. A method of accessing a side branch in an artery, comprising the steps of: providing a catheter having an inner tube and an outer tube arranged for rotational and/or telescoping movement relative to each other, said inner tube having an internal lumen and a first port at a distal end of the inner tube, said outer tube having a second port distal of said first port, said first port being offset from said second port relative to a longitudinal axis of the catheter, and a perforating guide wire extending through said internal lumen and exiting from the inner and outer tubes through the first and second offset ports, respectively, said perforating guide wire being engaged by said second port; and moving said outer tube relative to said inner tube to cause relative movement between said first and second ports to change the relative positions of said first and second ports to adjust an angle of the perforating guide wire exiting the catheter.
