Abstract: Irrigation devices, methods, and systems are disclosed. The system comprises a catheter with one or more lumens and an expandable portion. One or more pumps are used to supply a mixture of contrasting and dilating agents in an interior kidney volume and flush a portion of the mixture out of the interior kidney volume. The method comprises placing a catheter into the interior kidney volume through a ureter, occluding a portion of the ureter with a distal end of the catheter, forming an exit port through an exterior kidney surface, flowing the contrasting and dilating agents through the one or more lumens to supply the mixture in the interior kidney volume, and flushing a portion of the mixture out of the exit port.

Abstract: A medical device may include a stabilizer configured to be coupled to a port of an insertion device. The medical device may further include a shaft configured for telescopic translation within the stabilizer and a grip coupled to the shaft. Further, the medical device may include an actuator coupled to the grip. The actuator may be axially moveable relative to the grip so as to selectively actuate a distal assembly of the medical device.
