Abstract: A method of assembling a rotor is provided, in which each rotor disk comprising a connecting element. The method includes: (a) applying heat to a localized region of a first rotor disk of a plurality of rotor disks to selectively deflect a first connecting element of the first rotor disk, wherein the first rotor disk is stationary during heating; (b) installing the first rotor disk onto a rotor stack containing at least one rotor disk; and (c) repeating steps (a) and (b) for each rotor disk of the plurality of rotor disks; and (d) allowing the rotor disks, when stacked, to cool. When cooled, the respective connecting element of each rotor disk that has been selectively deflected contracts into an interference fit with an adjacent rotor disk.

Abstract: Disclosed herein are apparatuses and methods incorporating an infusion pump and a CGM that can include software that automatically populates a blood glucose section of a bolus calculator with a most recent valid CGM value. The software can additionally be programmed to automatically populate the bolus calculator with a single CGM reading only when one or more predefined conditions are met that aid in mitigating the risk of inaccurate and/or invalid single CGM readings.

Abstract: A user-wearable patch pump system for delivery of insulin or other medicament can include a patch pump having a reusable drive unit and a replaceable and refillable cartridge. The cartridge can selectively attach to and be detached from the drive unit. The cartridge can initially be inserted onto the drive unit in a first orientation at an angle to the drive unit and then be rotated to align the cartridge with the drive unit and lock the cartridge in place on the drive unit to form the patch pump.

Abstract: Disclosed herein are apparatuses and methods that account for exercise in closed loop insulin delivery systems. Rather than increasing a target insulin on board (IOB) as glucose levels rise, which would increase insulin delivery to address the raised glucose levels, when a user indicates that the user will be exercising raised glucose levels are addressed by reducing the target IOB within the closed loop algorithm. By reducing the target IOB, the algorithm responds less aggressively to pre-exercise food, and does not build up the IOB that can cause dangerously low glucose levels once the exercise also begins lowering glucose levels.

Abstract: Disclosed herein are apparatuses and methods for improved use of infusion sites for infusion pumps. Apparatuses and methods for delivery of medicaments such as insulin disclosed herein can increase the effectiveness of therapy by more accurately determining when an infusion site is no longer absorbing insulin at an acceptable rate as well as determining the effectiveness of different infusion sites on the body with respect to each other and over time.

Abstract: A portable medical device includes an interface for accepting a power supply and enabling data transfer while still connected to a human body. The interface may include a universal serial bus interface and may be coupled to a data isolation chip and a power isolation chip. A power controlling processor may determine how the supplied power, e.g., voltage, is supplied to other components within the infusion device. Additional circuitry within the system may provide a secure power transfer within the device to ensure user safety and ensure that a high frequency noise is properly attenuated.

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 either through a cannula to an infusion site directly beneath the retention frame or through tubing to an infusion site displaced from the retention frame.

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: Methods and systems are disclosed wherein temperature in a device such as an ambulatory infusion pump is monitored during inductive charging of the device such that temperature-sensitive contents or components, such as, for example, insulin, particular circuitry and/or other components are not damaged. Temperature can be monitored in the device at one or more locations during inductive charging. If the temperature breaches one or more predetermined thresholds and/or is rising at a rate greater than one or more predetermined thresholds, charging can be suspended or provided at reduced power to prevent the temperature from further rising and damaging the contents and/or components of the device. One or more alerts associated with these events may also be triggered so that the user is aware of the situation and may take corrective action.

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: Disclosed herein are systems and methods for monitoring performance of an ambulatory infusion pump. An ambulatory infusion pump can include a reservoir configured to contain a medicament including a plunger at a proximal end of the reservoir and an outlet port at a distal end of the reservoir. A motor can be configured to cause linear motion of a pushrod to contact and move the plunger to cause medicament to flow from the reservoir out of the outlet port to a patient. An optical encoder can be employed to monitor a linear position of the pushrod. In addition, the optical encoder can be employed to monitor additional system conditions and/or a secondary encoder can be employed to monitor the performance of the optical encoder.
