    摘要： Embodiments of medical infusion pumps are provided that include structural elements for providing sources of compliance within a fluid path within the pump. Some preferred embodiments provide implantable infusion pumps with compliance positioned between an exit port of a pumping mechanism and an outlet (e.g. an opening in a catheter) of the infusion pump. Other embodiments provide compliance in fluid path in proximity to entrance port of the pumping mechanism. Insertion of compliance in a flow path that is down stream of the pumping mechanism may aid in minimizing negative effects associated with attempting to force fluid through a restricted flow path that is further down-stream, such as that offered by a catheter or other outlet component. Insertion of compliance before the pumping mechanism may aid in reducing negative effects associated with an up stream restricted flow path, such as that which might be offered by a rigid filter located between the reservoir and the pumping mechanism. Several structural components, assemblies, or configurations may be used as sources of compliance. For example, compressible structures (e.g. pillows, drums) are used within a side port of the infusion pump. The compressible structures may quickly distort to accommodate for a large impulse of fluid into the flow path that can not otherwise be readily dealt with. The compression, in turn, results in a restoring force being exerted that returns the structure substantially to its original volume so as to slowly force fluid from the flow path.

    摘要： A reservoir includes a reservoir body portion and a collecting portion. The reservoir body portion having a wall defining an interior volume for containing fluidic media, the reservoir having a first port in the reservoir body portion to be in fluid flow communication with the interior volume, the first port for expelling fluidic media from the interior volume as a plunger is moved within the reservoir. The collecting portion having a wall defining a volume in fluid flow communication with the interior volume, the volume of the collecting portion for collecting gas bubbles in the fluidic media as the fluidic media is expelled through the first port from the interior volume of the reservoir body portion, the reservoir having a second port in the collecting portion to be in fluid flow communication with the volume of the collecting portion, the second port for receiving fluidic media into the reservoir.

    摘要： At least one tab may extend through at least one opening in a retaining member configured to cover at least a portion of a head of a reservoir body and a portion of a septum supported by the head of the reservoir body. A retaining member may be configured to cover at least a portion of a first head of a reservoir body and a portion of a septum supported by the first head of the reservoir body, and the reservoir body may have a second head having at least one tab. A retaining member located in a head of a reservoir body may be for retaining a septum on the head of the reservoir body, and the head of the reservoir body may have at least one tab.
