Abstract: Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be "front-loaded" into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

Abstract: A system and method to enable treatment through cell therapy. The system can enable cell injection such as, for example, injecting beta cells/islets, cartilage cells, fat cells, and others. The system and method ensure that the delivery rate and delivered volume of the material pumped through a tube and into the injection needle is consistent over the course of the start-operation-stop process from run to run. The system and method can automatically stop delivery and alarm if an occlusion is detected during delivery.
