Abstract
Methods for aspiration and filtering of a bodily fluid containing undesired components are provided and for treatment of the bodily fluids in a sterile environment in preparation for reinjection of treated aspirate into a donor subject. The invention methods are particularly designed to facilitate transfection of aspirated cells with angiogenesis promoting molecules without danger to the technician or the donor prior to reinjection of the treated cells, either percutaneously or via a surgical opening via a catheter or injection needle. A pressure actuator attached to the sterile container is used to express treated fluids in precisely controlled volumes. The invention methods include delivery of treated fluids using a hand-held device with audible cues that correspond to an operator-selected injection volume and/or audible cues that correspond to needle penetration depth selected by the operator.
