APPARATUS AND METHOD FOR PERFORMING THROMBOLYSIS

摘要

An apparatus (10) for delivery of an infusate into a body lumen (12) to perform thrombolysis comprises a catheter (24) having an infusion section (40) defined by a plurality of infusion ports (42) for delivering the infusate. The infusion ports (42) are spaced axially apart along the length of the infusion section (40). A sheath (50) coaxially surrounds a portion of the catheter (24). The sheath (50) is axially movable relative to the catheter (24) to selectively uncover at least a portion of the infusion ports (42) and thereby control the amount and distribution of the infusate delivered by the infusion section (40).
