摘要： A medical device comprising an implantable subcutaneous access port having a septum penetrable by a needle; the septum having a cavity located between an outer wall and an inner wall, the cavity containing a flowable media comprising a plurality of displaceable particles arranged to move in response to the needle being inserted through the outer wall and into the cavity and reposition around the needle.

摘要： A variable volume infusion port is provided. The infusion port may include a port body having an internal fluid reservoir, a septum, a stem to fluidly couple to a catheter lumen, and a displaceable member disposed in the internal fluid reservoir. In a first position, the displaceable member is disposed proximate the septum, providing a relatively small fluid volume within the infusion port. Insertion of an injection device through the septum causes the displaceable member to move to a second location distal from the septum, providing a relatively large fluid volume within the infusion port for the duration the injection device remains in the infusion port. The displaceable member may include a rigid member operably coupled to a biasing element or a flexible member coupled to a biasing element.
