Abstract
A microcatheter for delivery of embolic fluids includes an outer member dimensioned for insertion within a blood vessel adjacent an embolization site. The outer member defines a first longitudinal lumen, and an inner member is selectively positionable within the first longitudinal lumen of the outer member. The inner member defines a second longitudinal lumen and has a delivery port in fluid communication with the second longitudinal lumen for passage and delivery of embolic fluids toward the embolization site. A valve is disposed within the outer member. The valve is dimensioned to establish a substantial seal about the inner member, to minimize entry of the embolic fluids within the first longitudinal lumen of the outer member subsequent to delivery thereof toward the embolization site.
