Publication number: 20030069543Abstract: 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.Type: ApplicationFiled: October 23, 2001Publication date: April 10, 2003Inventors: Kenneth W. Carpenter, Michelle Fourmont, E. Thomas Malphus, Kazuo Sasamine, Hong Li

Publication number: 20020049407Abstract: The present invention is directed to an automatic injection device containing a pre-loaded charge of medicament for automatically self-administering the medicament upon actuation thereof. The automatic injection device includes a housing assembly having an interior chamber, a filter assembly, an activation assembly and a needle assembly. In accordance with the present invention, the interior chamber may include a dry compartment for storing a predetermined dry charge of dry medicament therein, and a wet compartment for storing a predetermined amount of liquid injection solution therein. The filter assembly enhances the laminar flow of fluid between the wet compartment to the dry compartment prior to the pressurization of the liquid injection solution within the wet compartment.Type: ApplicationFiled: October 9, 2001Publication date: April 25, 2002Inventors: Robert L. Hill, John G. Wilmot, Steven M. Griffiths

Publication number: 20020004038Abstract: The delivery system of the present invention is comprised of at least two chambers which store, individually, an activated blood component and an inactivated blood component. The first chamber comprises an activating agent and a filter which may be one in the same thus allowing the formed clot to be triturated thereby isolating the thrombin from the clot. The second chamber stores the inactivated blood component that when mixed with thrombin will produce a gel. The first or second chamber may further contain agents which are desired to be delivered to a specific site. The unique design of the delivery system allows for ease in operation of combining two agents at a specific time and place.Type: ApplicationFiled: April 9, 2001Publication date: January 10, 2002Inventors: Robert F. Baugh, Lisa M. Lim, Julie S. Eaton, John G. Rivera, Victor D. Dolecek
