Abstract
The disclosure provides for an adjustable catheter system with isovolumetric suction and restoration of fluid for the removal of a thrombus and a method of use thereof. The catheter system includes an inner catheter and an outer sheath surrounding at least a portion of the inner catheter. The inner catheter may include at least three lumina extending from the proximal end to the distal end of the inner catheter, at least one infusion fenestration along the infusion segment, and a distal encapsulation balloon at the distal end. The outer sheath may include at least three lumina extending from the proximal end to the distal end of the outer sheath and a proximal encapsulation balloon at the distal end. The catheter system may further include an agitator for mechanical morcellation of the thrombus.
