摘要：
A method of treating an intravascular site in a patient includes spraying jets of treatment fluid out of spray orifices formed in an elongate catheter body, and changing an impingement pattern of the treatment fluid on material within the intravascular site in response to a torque induced by a back pressure of the jets. A thrombolysis catheter includes an elongate catheter body having a plurality of spray orifices formed in a body wall, and communicating with a fluid lumen longitudinally extending in the elongate catheter body. The plurality of spray orifices define a torque inducing spray jet pattern, whereby a back pressure of spray jets exiting the spray orifices induces a torque on the elongate catheter body.
