Abstract
The invention provides flow directed catheters and methods which are useful in introducing various fluids to a target site within a body lumen. In one exemplary embodiment, a flow directed catheter is provided which comprises a catheter body having a proximal end, a distal end and at least one axial lumen. At least one jet is in fluid communication with the axial lumen. The jet is angled toward the proximal end of the catheter body so that a fluid which is flowed through the axial lumen exits the jet to distally propel the catheter body.
