Abstract:
An assembly for introducing a closure material to seal a puncture site in a vessel, the closure material comprising a mixture of a first and a second fluid composition, the assembly comprisinga catheter having a proximal end and a distal end; at least one fluid delivery port adjacent the catheter distal end to occupy a position outside the vessel adjacent the puncture site; an expandable member distal to the fluid delivery port to extend through the puncture site and occupy a position inside the vessel while the at least one fluid delivery port occupies a position adjacent the vessel puncture site outside the vessel; a fluid delivery lumen in the catheter in fluid communication with the fluid delivery port; a guidewire lumen in the catheter sized to accommodate passage of a guide wire; one or more dispensers adjacent the catheter proximal end in fluid communication with the catheter lumen for dispensing the first and second fluid compositions into the catheter lumen; an actuator for causing the first and second fluid compositions to be dispensed from the one or more dispensers for passage through the catheter lumen; and a static mixer in a downstream flow direction from the actuator and in a upstream flow direction from the catheter lumen for mixing the first and second fluid compositions prior to passage through the catheter lumen.
