Abstract: A device for infusing liquid medicaments such as insulin includes an infusion pump. The device can modify an insulin delivery protocol stored in memory to delivery an alternative insulin delivery protocol with the pump.

Abstract: Portable or ambulatory infusion devices and systems capable of remotely updating an ambulatory fluid delivery device include safety protocols that verify the status of the ambulatory fluid delivery device before and after a field update of software. Methods of accomplishing the same field update of software are also described.

Abstract: Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Abstract: A portable medical device is operated in an active mode in which the device receives a user input at an input interface and provides the received user input to a processor of the device. The active mode is terminated and the device is operated in a safe mode, in which the received user input is not provided to the processor and/or one or more device function is disabled, in response to determining that the received user input was received in an out of bounds region of the input interface. The safe mode is terminated in response to receiving a predetermined user input comprising an activation input.

Abstract: A portable insulin pump can integrate and display data from a continuous glucose monitor (CGM) to allow a user to more readily determine whether any interaction with the pump is necessary. Data from the CGM can automatically be transmitted to the pump and can be displayed for user analysis or automatically analyzed to present recommendations to the user based on combined data from the CGM and the pump.

Abstract: A user-wearable infusion pump system includes an inductively or otherwise wirelessly chargeable battery and at least one button. Activation of the at least one button when not in the presence of an inductive charging signal can enable and/or initiate a first function or operation and activation of the at least one button in the presence of an inductive charging signal can enable and/or initiate a different, second function or operation. Such functionality can also be enabled in the presence of other types of electromagnetic signals.

Abstract: An apparatus comprises receiving a user prompt in a blood glucose (BG) management device to start a determination of an effective correction factor, receiving sampled blood glucose data of a patient obtained during a specified time duration, including a time duration after delivery of an initial insulin correction bolus, determining the effective correction factor using the BG management device according to a determined decrease in the blood glucose level of the patient and an amount of insulin in the initial insulin correction bolus, and cancelling the determination of the effective correction factor if a blood glucose level of the patient is outside of a specified range of blood glucose levels.

Abstract: A user-wearable patch pump system for delivery of insulin or other medicament can include a pump and an attachment portion that attaches the pump to a user's body. The pump can include a drive unit and a disposable cartridge containing a medicament with the drive unit configured to cause the pump to deliver the medicament in the cartridge to the user. The attachment portion can include a retention frame configured to selectively retain the pump therein and an adhesive patch configured to be attached to the user's body. The pump can be selectively attached to the retention frame and used to deliver medicament through tubing to an infusion site displaced from the pump.

Abstract: Apparatuses and methods for delivery of medicaments such as insulin disclosed herein can increase the effectiveness of therapy by adjusting medicament delivery parameters to account for the loss of medicament absorption upon delivering medicament at a new insertion site. When a needle is inserted at a new site on a patient's body for delivery of medicament to that patient, a natural inflammatory response by the body to insertion of the needle causes the body to resist absorption of the delivered medicament. However, this medicament resistance decreases over time. Embodiments of the invention therefore adjust medicament delivery to deliver less medicament as time passes after an infusion set change causes medicament to be delivered at a new insertion site.

Abstract: A patch pump utilizes piezoelectricity to dispense medicament from a cartridge syringe to a patient. Pump can include a plurality of piezoelectric elements that when energized cause linear motion of a pushrod that interfaces with the syringe in the cartridge to advance the syringe and dispense the medicament. The high torque generated by the piezoelectric elements is directly converted into the same amount of torque on the lead screw, so no torque increasing gear reduction system is needed and the pushrod utilized to drive the syringe can be contained within and connected directly to the motor assembly. Such a piezoelectric-based system can therefore be made smaller and with fewer moving parts than an electromagnetic motor of the same capability such that the pump has a smaller size than has heretofore been possible with prior art electromagnetic-based syringe pumps and other pumps that utilize gear reduction systems.

Abstract: Devices and methods are disclosed for transferring fluids from supply reservoirs. The devices and methods may be configured to prevent or reduce the incidence of a user transferring a fluid to an incorrect receptacle reservoir.

Abstract: A system and method provide for enhanced reliability and safety of programming and/or operating a medical device, such as an infusion pump. A safety processor can check whether an operating command is within acceptable parameters.

Abstract: A simplified insulin pump allows type II diabetics to identify routine patterns in their daily lifestyle that provide a generally accurate typical pattern of activity and meals. An infusion regimen can be programmed into the pump that generally correlates with this typical pattern to provide a viable treatment option for a type II diabetic without the need for specific and precise matching of insulin to carbohydrate consumption or activity level.

Abstract: An apparatus comprising a pump, a user interface, and a controller communicatively coupled to the pump and the user interface. The controller is adapted to receive information relating to a blood glucose level of a user, determine whether the blood glucose level differs from a target blood glucose level by a threshold value, and selectively provide or delay provision of an alert notifying the user to check the user's blood glucose level. Other devices, systems, and methods are disclosed.

Abstract: An apparatus for delivering a bolus of a medical agent to a patient. The apparatus comprises a pump mechanism, a data input device, and a processor in data communication with the keypad and arranged to control the pump mechanism. The processor is programmed to receive data specifying a bolus amount through the data port, receive data regarding duration through the data port, receive a percentage through the data port, the percentage defining a portion of the bolus amount to deliver immediately upon executing a deliver command and a remainder of the bolus amount to deliver over the duration upon executing a deliver command, and execute the deliver command thereby controlling the pump mechanism to deliver the bolus. Also a method of temporarily adjusting the delivery rate of an infusion pump. The infusion pump is programmed to deliver a basal rate.

Abstract: A computer implemented method of determining a clinical variables utilizing an insulin pump that includes initiating blood glucose measurements, initiating ingestion of carbohydrates and receiving input data based on the blood glucose measurements and the ingestion of carbohydrates and utilizing the data to calculate clinical variables. The invention may include presenting instructions to a patient to take various actions and to input various data. The clinical variables determined may be stored in memory and then used to calculate insulin doses and to send a signal to an insulin pump to infuse the insulin dose calculated.
