Abstract
Described herein are systems, devices and methods that enable dynamic modification of the physicochemical properties of a hydrogel during its in vivo formation and delivery by a catheter. In some example embodiments, an extended endoluminal hydrogel delivery device is employed for delivering a hydrogel within a given body cavity, such as within the lumen of a blood vessel. In some example embodiments, a hydrogel precursor, as a non-viscous liquid, is injected through an intravascular catheter and crosslinking of the hydrogel precursor is initiated within a distal region of the catheter. The crosslinking process is controlled, by a control means associated with a distal region of the catheter, to control or modify one or more properties of the hydrogel. The properties may be controlled such that a hydrogel is suitable to embolize the specific target or deliver drugs or other materials beneficial to the site.
