Title: CATHETERS WITH SIDE OPENINGS FOR MODIFYING AND DELIVERING SUSPENSIONS TO A SUBJECT
Abstract:
Microcatheters and methods for modifying and delivering suspended particles to target bodily parts (e.g., of the cardiovascular system). Embolization microcatheters and uses thereof in performing local embolization procedures, involving modifying flow characteristics (momentum) of suspensions during delivery. Applicable for delivering embolization material in a small blood vessel towards a target bodily part, and for performing local embolizations in small blood vessels feeding (possibly, cancerous) target bodily parts, thereby forming emboli therein, while preventing or minimizing non-target embolization. Exemplary catheter includes: tubular wall with proximal and distal wall ends, and lumen extending therebetween, opened and configured to allow passage of suspension to distal outlet; distal outlet is shaped or/and sized to allow passage of both suspension fluid and particles; proximal outlet is configured to allow passage of suspension fluid without particles and to block passage of particles, during delivery of suspension.
