ABSTRACT:
The present invention provides a catheter for use in delivering formulation that allows modification of the formulation prior to or concomitant with its transport or at a delivery site. The catheter comprises an elongate body, which defines an inner lumen extending between the proximal and distal ends, and a modifying element, which provides for modification of one or more components of a formulation prior to or concomitant with release at the delivery site.
