Abstract:
1. A method of retrograde venous perfusion of a tumor in a patient's body, comprising the steps of: positioning a withdrawal catheter within vasculature of a target vessel in the patient's body near the tumor; positioning an infusion catheter within the vasculature of the target vessel extending beyond the withdrawal catheter and near the tumor; concentrically disposing a venous pressure catheter between the infusion catheter and the withdrawal catheter; occluding the vasculature in the target vessel with the infusion catheter and the withdrawal catheter to form a closed loop retrograde perfusion flow path through the target vessel between the positioned infusion catheter and the positioned withdrawal catheter; monitoring venous pressure at the venous pressure catheter in the closed loop flow path; and circulating a chemotherapeutic agent, the chemotherapeutic agent having side effects on other organs in the patient's body, from the infusion catheter through the closed loop flow path in the target vessel to the withdrawal catheter.
