Estimating the term…
The invention provides systems containing a sterile container for aspiration, filtering, treating and reinjection into a subject of a bodily fluid in a sterile environment. The systems are particularly designed to facilitate transfection of cells within the sterile container by gene therapy molecules and reinjection of the transfected cells into the donor at controlled depth in precisely controlled volumes such as is useful for revascularization of ischemic cardiac tissue. For injection, a pressure actuator, preferably hand-held, applies force to liquids held within the sterile container in precisely controlled increments, thereby expressing liquids through a hollow needle or injection catheter in precisely controlled microvolumes. The invention systems include a hand-held injection 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.
An aspiration/injection system for a bodily liquid containing undesired components, said system comprising the following components:
