Abstract
Abstract A multi-component sealant applicator comprises a dual catheter for delivering sealant. Each catheter communicates with one of a pair of fluid sealant agent sources and comprises a mixing volume within the dual catheter for mixing multiple components of a multi-component sealant prior to discharge from a distal end of the catheter and a clearing system to clear undesired material from the mixing volume or the vicinity of the mixing volume, wherein one catheter is mounted for longitudinal movement within the other and the inner catheter is usable as a plunger to remove clogs. The catheter may comprise a reciprocal drive mechanism proximally coupled with the dual catheter to move one catheter longitudinally with respect to the other. The drive mechanism may comprise a ratchet and pawl.
