An implantable fluid-dispensing device having an improved fluid-retainment portion is disclosed as having a housing having a first end and a second end, wherein at least a portion of one of the first end and second end comprises an expandable material, and a thermally activated component associated with the elastic material within the housing wherein the thermally activated component prevents unwanted fluid flow when the housing is exposed to a temperature increase. The thermally activated component can be a shaped single or bimaterial member that expands upon exposure to a temperature increase, or a valve apparatus that halts fluid delivery. Additionally, the entire device can be made from a thermally activated material such that fluid expansion is accommodated. A method for the prevention of the inadvertent release of fluid from a fluid delivery device that is exposed to a temperature increase is also disclosed.
