Abstract: A therapeutic fluid delivery system including, in various examples, a first reservoir configured to house a first therapeutic fluid, a second reservoir configured to house a second therapeutic fluid, and an inlet port configured to receive a fluid delivery needle is described. The inlet port is configured for fluid communication between the fluid delivery needle and the first reservoir, and the inlet port is further configured for fluid communication between the fluid delivery needle and the second reservoir.

Abstract: The disclosure is directed to a pressure sensor of an implantable medical device. The pressure sensor may utilize detect fluid pressure based on a changing capacitance between two capacitive elements. The pressure sensor may define at least a portion of a fluid enclosure of the IMD. In one example, the pressure sensor has a self-aligning housing shape that occludes an opening in the pump bulkhead of the IMD. An operative surface of the pressure and the portion of the fluid enclosure may be formed of a corrosion resistant and/or biocompatible material. A first capacitive element of the pressure sensor may be a metal alloy diaphragm that deflects in response to external fluid pressure. A second capacitive element of the pressure sensor may be a metal coating on a rigid insulator sealed from the fluid by the diaphragm and a housing of the sensor.

Abstract: An actuator for an infusion drive mechanism comprises a piston defining a first axis and being movable within a passageway of the infusion drive mechanism to convey at least one infusion medium. The passageway defines a longitudinal axis. An armature is connected to the piston and defines at least one cavity configured for disposal of a biasing member engageable with a surface of the infusion drive mechanism to orient the first axis transverse relative to the longitudinal axis. Systems and methods of use are disclosed.
