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: 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.

Abstract: A novel enhanced infusion pump system is adapted for dispensing medicament from a flow material reservoir Software used in conjunction with a pressure sensor can determine a backstroke volume of medicament that can be used to calculate the volume of medicament in the flow material reservoir.

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: Occlusions in a delivery line of an infusion pump can be detected by measuring pressure differentials in the pump over short periods of time in order to minimize the effects of long term systematic sensor changes. In a delivery mode such as basal insulin delivery where a small portion of a volume of fluid is delivered, pressure readings can be obtained before and after the motor move to deliver each portion and compared. The differentials after one or more motor moves can be compared to determine whether an occlusion is present. In a delivery mode such as bolus insulin delivery in which an entire volume of fluid is delivered, pressure differentials can be obtained for consecutive deliveries at a common point in the delivery cycle of each delivery. Comparison of these pressure values can be used to determine whether an occlusion is present.

Abstract: An ambulatory infusion pump can include a maximum bolus override procedure. When a bolus amount greater than a maximum bolus amount is requested, the pump can provide an alert indicating that the amount requested exceeds the maximum bolus amount. If the user confirms the request in response to the alert, the bolus amount can be delivered to the user. The amount delivered in response to the confirmation can be a first portion of the bolus amount. A reminder can then be provided that a second portion of the bolus amount that is a remaining portion of the requested bolus amount was also requested. If a second confirmation is received in response to the alert, the second portion of the bolus amount can also delivered to the user.

Abstract: This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid from a cartridge, a display a temperature sensor and a controller. The controller is configured to compare a temperature within the cartridge as measured by the temperature sensor to a threshold temperature and cause the display to display a message relating to temperature when the measured temperature goes beyond the threshold temperature.

Abstract: A portable infusion pump can communicate with glucose monitor, such as a continuous glucose monitor (CGM), to receive continuous feedback relating to a user's blood glucose level during insulin or other medicament therapy and can automatically deliver insulin to a user when the CGM data indicates a need for additional insulin. Due to potential unreliability in the correlation of the CGM data to the user's actual blood glucose level, risk mitigation can be employed to limit the amount of extra insulin that can be delivered by the pump in response to the CGM data.

Abstract: A portable insulin pump can utilize readings from a sensor incorporated into an infusion set used with the pump to deliver insulin to a patient to determine if the infusion set is or is likely to become dislodged from the patient. Readings from the sensor that are inconsistent with expected readings or a range of expected readings can indicate that the infusion set has become dislodged from the patient.
