  • Method of treating an intravascular site in a patient, and thrombolysis catheter therefor
    Patent number: 9314589
    Abstract: 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.
    Type: Grant

  • Infusion mechanism and method
    Patent number: 9205224
    Abstract: An infusion mechanism for treating an intraluminal site in a patient includes an infusion catheter having an elongate body with a proximal body end defining at least one fluid supply orifice, and a distal body end. The elongate body defines a high head loss lumen in fluid communication with a first set of side ports defining a proximal infusion zone. The elongate body further defines a low head loss lumen in fluid communication with a second set of side ports defining a distal infusion zone.
