Abstract:
1. A method of using a catheter, comprising: advancing a catheter body into a patient's vasculature over a guidewire positioned within a bodily vessel, the catheter body comprising a proximal end, a distal end, a first lumen extending axially through at least a portion of the catheter body, an opening extending laterally through the catheter body in communication with the first lumen, and a bend adjacent to the opening; increasing the working length of the catheter body by moving the catheter body from a first configuration to a second configuration to reduce an the angle of the bend while the opening extending laterally through at least a portion of the catheter body is positioned outside the patient's body, the angle of the bend of the catheter body and the first lumen being smaller in the second configuration than in the first configuration; and advancing the catheter body over the guidewire positioned within a bodily vessel so that the guidewire passes through the first lumen and past the opening of the catheter body without passing through the opening.
