    摘要： A catheter for use in delivery or withdrawal of a formulation, wherein the catheter has an outer layer comprising a bio-compatible material and a barrier layer comprising a material that provides a more effective barrier than the outer layer against inward and outward diffusion of substances that may cause destabilization of the formulation. The catheter may include a flared distal end tip to aid in the release, during a bolus delivery or catheter flush, of any obstruction situated at the distal end tip of the catheter. The catheter may also include a slit valve at the distal end tip which has one or more and, preferably a plurality of slits that may be elastically extended to an open position by the expulsion of the formulation during an IIP pump stroke. During the interval between IIP pump strokes, the slits return to a closed position and hinder the inflow of body fluid into the distal end tip.

    摘要： A medication infusion device such as a programmable infusion pump includes data input regarding a selected patient parameter such as a current blood glucose reading. The infusion device includes a controller responsive to this data input to develop a medication delivery protocol which can be implemented automatically, recommended via a display for subsequent approval or rejection upon manipulation of control switches, or otherwise overridden in favor of a different medication delivery protocol.

    摘要： An implantable medication delivery device that is highly space efficient and can reliably and safely deliver controlled medication doses to a target site. The system includes a variable volume medication reservoir that is exposed to an ambient pressure equal to the ambient pressure at a system outlet port. A pump/valve subassembly is provided to draw medication from the reservoir and force a medication dose along a fluid transfer passageway to the outlet port. The pump/valve subassembly incorporates a safety mechanism, e.g., a balanced valve, which normally blocks medication flow to the outlet port and opens only in response to a pump induced unbalancing force. A protective shell is also disclosed for protecting the ambient reservoir.
