Abstract
Techniques are disclosed for reducing the accumulation of gases in an implantable infusion device. In one example, an implantable infusion device (IID) includes a housing, an expandable and contractible reservoir, and a standoff member. The expandable and contractible reservoir is configured to store a therapeutic agent and is arranged within the housing. A first end of the reservoir is configured to collapse toward a second end of the reservoir as the reservoir contracts. The standoff member is interposed between the first end and the second end of the reservoir and is configured to hold at least a portion of the first end offset from the second end when the reservoir is in a contracted state.
