A medical device system. The system includes a first medical device, a first remote interface, and a second remote interface in communication with the first remote interface and the first medical device, wherein the first medical device sends a command to the first medical device through the second remote interface, and wherein when the second remote interface receives the command, the command must be confirmed by the second remote interface before the command is send by the second remote interface to the first medical device.

Electrochemical Impedance Spectroscopy (EIS) is used in conjunction with continuous glucose monitors and continuous glucose monitoring (CGM) to enable in-vivo sensor calibration. gross (sensor) failure analysis, and intelligent sensor diagnostics and faith detection. An equivalent circuit model is defined, and circuit elements are used to characterize sensor behavior.

Techniques disclosed herein relate generally to alert management based on sleeping status. In some embodiments, the techniques involve obtaining user status data indicative of a sleeping status of a user of a medical device, and controlling alert generation and output associated with the medical device in accordance with the sleeping status of the user.

An infusion pump assembly includes a locking tab and a pump barrel inside a pump barrel housing, where the pump barrel accommodates a reservoir assembly. The reservoir assembly includes a reservoir and a plunger rod. The infusion pump assembly also includes a locking disc at a terminus of the pump barrel. The locking disc includes a clearance hole for the plunger rod. The locking disc also includes at least one locking tab notch in close proximity with the locking tab. The locking tab is in moveable engagement with the locking tab notch, and the reservoir moves the locking tab from a locked position to an unlocked position when the plunger rod is inserted through clearance hole. The locking disc rotates upon torque being applied to the reservoir assembly, the locking disc rotating from a non-loaded position to a loaded position with respect to the plunger rod and a drive screw.

A system and method for delivering a medicament to a target tissue site in a patient over a period of time. A catheter is configured for implantation in different target tissue sites and extends from a proximal end to a distal end and has a sidewall which defines an internal lumen. The distal end has one or more apertures either in the sidewall or at a distal end for the release of the medicament into the target tissue site; the system also comprises a medicament reservoir fluidly communicable with the internal lumen of each catheter, an adhesive member configured to adhere to the skin of the patient around the exit wound and having an opening therein to allow the catheters to pass through the adhesive member and a retaining member configured to be overlaid on the adhesive member and comprising a guide surface configured to receive a length of the two or more catheters and a plurality of retaining portions to retain the catheters against the guide surface.

Techniques disclosed herein relate to determining a calibrated measurement value indicative of a physiological condition of a patient using sensor calibration data and a performance model. In some embodiments, the techniques involve obtaining one or more electrical signals from a sensing element of a sensing arrangement, where the one or more electrical signals are influenced by a physiological condition in a body of a patient. The techniques also involve obtaining calibration data associated with the sensing element from a data storage element of the sensing arrangement, converting the one or more electrical signals into one or more calibrated measurement parameters using the calibration data, obtaining a performance model associated with the sensing element, obtaining personal data associated with the patient, and determining, using the performance model and based on the personal data and the one or more calibrated measurement parameters, a calibrated output value indicative of the physiological condition.

Some embodiments of an infusion pump system may be configured to allow the user to communicate with the infusion pump system using voice or image input. Optionally, particular embodiments can interpret the voice or image input using speech or image recognition capabilities. By incorporating speech or image recognition equipment within the infusion pump system, user interactions with the pump system can be enhanced and simplified.

Provided are an electroosmotic pump including a membrane; a first electrode disposed on a surface of the membrane and including a first porous support including a first conductor and a first precious metal and a first conductive polymer positioned in or on at least some of pores and surfaces of the first porous support; and a second electrode disposed on another surface of the membrane and including a second porous support including a second conductor and a second precious metal and a second conductive polymer positioned in or on at least some of pores and surfaces of the second porous support, a method of manufacturing the electroosmotic pump, and a fluid pumping system including the electroosmotic pump.

A disease management system including a medication delivery pump configured to deliver a medication from a medication pouch to a patient. The medication delivery pump may include one or more plungers configured to interrupt a flow path of medication from a medication reservoir to a patient, one or more muscle wires, and one or more disc shaped springs. The one or more muscle wires and disc shaped springs may be configured to move the one or more plungers to interrupt and uninterrupt the flow path of medication towards a patient from a medication pouch.

Disclosed in some embodiments is an electronic intravenous infusion pump provided with a disposable, insertable pump cartridge that is connectable to one or more intravenous fluid infusion sources, wherein a user interface on a touch display screen interacts with and responds to the user's insertion of the cassette, and/or wherein the pump is enabled to program a course of infusion for a patient based upon information obtained from the inserted cassette and/or the one or more fluid infusion sources connected to the cassette.
