Abstract
The invention includes a catheter having an elongate main body portion and a distal body portion. The elongate main body portion has a proximal end and a distal end. The main body portion further includes a coil having at least one complete turn about a central axis, the coil defining a passage along the central axis. The elongate distal body portion extends from the distal end of the main body portion. In accordance with a further aspect of the invention, the distal body portion has a proximal end and a distal end and can include a guidewire lumen defined along at least a portion of a length between the distal end and the proximal end of the distal body portion. The guidewire lumen has a distal guidewire port and a proximal guidewire port defined in communication therewith. The passage can be in fluid communication with an exterior of the catheter.
