Abstract
An infusion flow guidewire system and method of use. The infusion flow guidewire system includes a delivery sheath and an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a flexible tip having a closed distal end, a coil, a core wire and at least one distally located jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.
