A processing system includes a processor including a separator, a set configured to cooperate with the separator to separate whole blood into plasma and other components, the set including an inlet line attachable to a patient to receive whole blood and an return line attachable to a patient to return processed fluid, and a source of replacement fluid connected to the disposable set, the processor configured to combine the other components with replacement fluid to define the processed fluid. The processor includes a controller and an input device coupled to the controller, the controller configured to receive an input via the input device, the input representing a volume of replacement fluid, and to control the processor to separate whole blood passing through the set and to combine the other components with the replacement fluid according to the input until the source of replacement fluid is empty.

Rapid exchange balloon catheter, and applications thereof. The balloon catheter includes a shaft and a guidewire channel. Shaft includes infusion and inflation walls. Infusion wall encloses an infusion lumen and comprises fluid inlet and fluid outlet located distally to fluid inlet. The inflation lumen extending axially therealong opened at a distal end thereof into an inner volume of a dilatation balloon. Guidewire channel is sized to closely fit over a pre-scribed guidewire for allowing unhindered passing therethrough with the guidewire. Guidewire channel includes a channel distal end protruding distally from the balloon with a distal guidewire opening, and a channel proximal end with a proximal guidewire opening at the shaft between fluid inlet and fluid outlet. Applications include methods for angioplasty and revascularization in which a single balloon catheter is used for dilatation and/or occlusion, and for delivering fluid proximally to the balloon.

A system of authenticating a medical solution used in a blood processing procedure, comprising a blood processing system having a user interface and access to a database of medical solutions identifiable by identifiers, wherein the blood processing system guides a user through steps of the procedure and the user interface prompts the user to execute an action as part of a step; a fluid circuit having an inlet for a medical solution, wherein the fluid circuit is coupled to the fluid processing system; wherein a step of the blood processing procedure comprises drawing a solution into the circuit, wherein the interface receives a user input of an identifier of the solution prior to the fluid processing system executing the step; wherein the fluid processing system is configured to compare the received identifier to medical solution identifiers within the database and, based on a result of the comparison, executing the step.
