Abstract:
1. A pneumatically-operated thrombectomy catheter deployment system comprising a prepackaged disposable combination of: a. a thrombectomy catheter drive unit connected to a nondisposable compressed gas source, the drive unit including: b. the effluent pump opposing the high pressure pump such that both are operated by the double-acting air cylinder and maintain isovolumetric flow of the fluid being pumped into and then out of a patient, and c. a thrombectomy catheter having a distal portion and a proximal portion, said proximal portion being operatively connected to the thrombectomy catheter drive unit and the effluent pump such that the fluid is supplied to the thrombectomy catheter and said fluid emanates from the distal portion of the thrombectomy catheter at an increased pressure in a cross stream flow pattern.
