Abstract
A fluid reservoir for a medical infusion system includes an expandable elastomeric bladder defining a chamber for receiving and containing a volume of therapeutic substance and exerting pressure thereon to dispense the therapeutic substance from the bladder. The bladder has preferably a single port formed through the thickness thereof. A bi-directional valve is in fluid communication with the chamber of the elastomeric bladder and is used for filling the bladder chamber with the therapeutic substance and for connecting to a catheter assembly for dispensing the therapeutic substance to a patient undergoing treatment. The single port of the elastomeric bladder is connected to a medical grade flexible tubing, which is also connected to the bi-directional valve.
