[0003] 63 / 719,429, filed November 12, 2024, and U.S. Provisional Patent Application No.

[0004] 63 / 719,453, filed November 12, 2024, each of which is hereby incorporated herein by reference in its entirety.

[0005] TECHNICAL FIELD

[0006] The present disclosure relates generally to ambulatory infusion pumps and, more particularly, to operation of ambulatory infusion pumps in conjunction with a continuous glucose monitor.

[0007] BACKGROUND

[0008] There are a wide variety of medical treatments that include the administration of a therapeutic fluid in precise, known amounts at predetermined intervals. Devices and methods exist that are directed to the delivery of such fluids, which may be liquids or gases, are known in the art.

[0009] One category of such fluid delivery devices includes insulin injecting pumps developed for administering insulin to patients afflicted with Type 1 or Type 2 diabetes. Some insulin injecting pumps are configured as portable or ambulatory infusion devices that can provide continuous subcutaneous insulin injection and / or infusion therapy as an alternative to multiple daily injections of insulin via a syringe or an insulin pen. Such pumps can be worn or carried by the user and may use replaceable cartridges. In some embodiments, these pumps may also deliver medicaments other than, or in addition to, insulin, such as glucagon, pramlintide, and the like. Examples of such pumps and various features associated therewith include those disclosed in U.S. Patent Publication Nos. 2013 / 0324928 and 2013 / 0053816 and U.S. Patent Nos.

[0010] 8,287,495; 8,573,027; 8,986,253; and 9,381,297, each of which is incorporated herein by reference in its entirety.

[0011] Ambulatory infusion pumps for delivering insulin or other medicaments can be used in conjunction with blood glucose monitoring systems, such as continuous glucose monitoring devices (CGMs). A CGM device may consist of a sensor placed under the patient’s skin and affixed to the patient via an adhesive patch, a transmitter, and a monitor. A CGM device samples the patient’s interstitial fluid periodically (e.g., once every 1-5 minutes) to estimate blood glucose levels over time. CGMs are advantageous because they provide more frequent insights into a user’s blood glucose levels yet do not require a finger stick each time a reading is taken.

[0012] Ambulatory infusion pumps may communicate with a dedicated CGM directly via a wired connection or indirectly via a wireless connection using wireless data communication protocols to communicate with a separate device (e.g., a dedicated remote device or a smartphone). One example of integration of ambulatory infusion pumps with CGM devices is described in U.S. Patent Publication No. 2014 / 0276419, which is hereby incorporated by reference herein. Ambulatory infusion pumps typically allow the user or caregiver to adjust the amount of insulin or other medicament delivered by a basal rate or a bolus, based on blood glucose data obtained by a CGM device, and in some cases include the capability to automatically adjust such medicament delivery. For example, based on CGM readings, some ambulatory infusion pumps may automatically adjust or prompt the user to adjust the level of medicament being administered or planned for administration or, in cases of abnormally low blood glucose readings, reducing or temporarily ceasing insulin administration.

[0013] While integrations of CGM devices with insulin pumps provides a number of advantages, the CGM sensor and pump are separately attached to the body resulting in a cumbersome and visually unappealing dual device configuration. Both the pump and the CGM also need to each have a battery, processor, communications element, etc. In addition, in order to establish wireless communications between the devices a pairing procedure must be undertaken. Patients are therefore burdened with managing two distinct systems, each with its own power source and attachment method, leading to increased complexity, higher costs and a less streamlined user experience.

[0014] SUMMARY

[0015] Ambulatory infusion pump systems can integrate a CGM sensor with an ambulatory infusion pump via a pump holder or tray that releasably holds the pump and is configured to be worn by a user. By combining the CGM and insulin pump into one integrated system, a more aesthetically pleasing, convenient and reliable system is provided. Diabetes management is simplified by consolidating two essential devices into one.

[0016] Embodiments disclosed herein are directed to ambulatory infusion pump systems that integrate a CGM sensor with an ambulatory infusion pump via a pump holder or tray that releasably holds the pump and is configured to be worn by a user. An inductive coupling between the pump and the CGM can both provide power from the pump to the CGM sensor and facilitate communications between the CGM sensor and the pump. By combining the CGM and insulin pump into one integrated system with inductive power transmission, a more aesthetically pleasing, convenient and reliable system is provided. Diabetes management is simplified by consolidating two essential devices into one.

[0017] Embodiments disclosed herein are directed to ambulatory infusion pump systems that integrate a CGM sensor with an ambulatory infusion pump via a pump holder or tray that releasably holds the pump and is configured to be worn by a user. A direct electrical connection between the pump and the CGM can be facilitated by a power bridge that provides for power from the pump to the CGM sensor and facilitates communications between the CGM sensor and the pump. By combining the CGM and insulin pump into one integrated system with a direct electrical connection, a more aesthetically pleasing, convenient and reliable system is provided.

[0036] DETAILED DESCRIPTION OF THE DRAWINGS

[0037] The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.

[0038] FIG. 1 depicts an exemplary medical device that can be used with embodiments of the disclosure. In this embodiment, the medical device is configured as a pump 12, such as an infusion pump, that can include a pumping or delivery mechanism and reservoir for delivering medicament to a patient and an output / display 44. The type of output / display 44 may vary as may be useful for a particular application. The output / display 44 may include an interactive and / or touch sensitive screen 46 having an input device such as, for example, a touch screen comprising a capacitive screen or a resistive screen. The pump 12 may additionally include a keyboard, microphone, or other input device known in the art for data entry, which may be separate from the display. The pump 12 may also include a capability to operatively couple to one or more blood glucose meters (BGMs) or continuous blood glucose monitors (CGMs) and / or one or more secondary devices such as a remote display, a remote control device, a laptop computer, personal computer, tablet computer, a mobile communication device such as a smartphone, a wearable electronic watch, smart ring, electronic health or fitness monitor, or personal digital assistant (PDA), a CGM display etc.

[0039] In one embodiment, the medical device can be a portable pump configured to deliver insulin to a patient. Further details regarding such pump devices can be found in U.S. Patent No. 8,287,495, which is incorporated herein by reference in its entirety. In other embodiments, the medical device can be an infusion pump configured to deliver one or more additional or other medicaments to a patient.

[0040] FIG. 2 illustrates a block diagram of some of the features that can be used with embodiments, including features that may be incorporated within the housing 26 of a medical device such as a pump 12. The pump 12 can include a processor 42 that controls the overall functions of the device. The infusion pump 12 may also include, e.g., a memory device 30, a transmitter / receiver 32, an alarm 34, a speaker 36, a clock / timer 38, an input device 40, a user interface suitable for accepting input and commands from a user such as a caregiver or patient, a drive mechanism 48, an estimator device 52, and a microphone (not pictured). One embodiment of a user interface as shown in FIG. 2 is a graphical user interface (GUI) 60 having a touch sensitive screen 46 with input capability. In some embodiments, the processor 42 may communicate with one or more other processors within the pump 12 and / or one or more processors of other devices, for example, a continuous glucose monitor (CGM), display device, smartphone, etc. through the transmitter / receiver. The processor 42 may also include programming that may allow the processor 42 to receive signals and / or other data from one or more input devices, such as sensors that may sense pressure, temperature and / or other parameters.

[0041] FIGS. 3A-3B depict a second infusion pump that can be used in conjunction with one or more embodiments of the ambulatory infusion pump system of the present disclosure. Pump 102 includes a pump drive unit 118 and a medicament cartridge 116. Pump 102 includes a processor 42 that may communicate with one or more processors within the pump 102 and / or one or more processors of other devices such as a remote device (e.g., a CGM device), a remote control device, or a consumer electronic device (e.g., laptop computer, personal computer, tablet computer, smartphone, electronic watch, smart ring, electronic health or fitness monitor, or personal digital assistant). The processor 42 may also include programming to receive signals and / or other data from an input device, such as, by way of example, a pressure sensor, a temperature sensor, or the like. Pump 102 also includes a processor that controls some or all of the operations of the pump. In some embodiments, pump 102 receives commands from a separate device for control of some or all of the operations of the pump. Such separate device can include, for example, a dedicated remote device or a consumer electronic device such as a smartphone having a processor executing an application configured to enable the device to transmit operating commands to the processor 42 of pump 102. In some embodiments, processor 42 can also transmit information to one or more separate devices, such as information pertaining to device parameters, alarms, reminders, pump status, etc. Such separate device can include any remote display, remote device, remote control, or a consumer electronic device as described previously.

[0042] Pump 102 can also incorporate any or all of the features described with respect to pump 12 in FIG. 2. In some embodiments, the communication is effectuated wirelessly, by way of example only, via a near field communication (NFC) radio frequency (RF) transmitter or a transmitter operating according to a “Wi-Fi” or Bluetooth® protocol, Bluetooth® low energy protocol or the like. Further details regarding such pumps can be found in U.S. Patent No. 10,279,106 and U.S. Patent Publication Nos. 2016 / 0339172 and 2017 / 0049957, each of which is hereby incorporated herein by reference in its entirety.

[0043] FIG. 4 depicts a schematic representation of a pump system 200 according to an embodiment of the disclosure. System 200 includes a user-wearable infusion pump such as pump 12 or pump 102 described above. In embodiments, a user can alternatively wear the pump 102 A directly on the body or place the pump 102B in the user's pocket or other location near the body with infusion tubing 144 extending to an infusion set 148 on the user's body. The system 200 also includes a continuous glucose monitoring (CGM) sensor with a corresponding transmitter 208. The CGM sensor obtains measurements relating to glucose levels in the body and the transmitter can communicate that information to pump 102A / B. Pump 208 can then use the glucose data in making therapy determinations. The system can also include one or more devices such as a smartphone 204 or other multi-purpose consumer electronic device capable of operating a software application to communicate with and / or control the pump and, alternatively or additionally, a dedicated remote device designed specifically for use with pump 102A / 102B. The smartphone 204 or other remote electronic device can in some embodiments also be capable of communication with CGM sensor / transmitter 208 and can calculate therapy commands for execution by the pump 102A / 102B based on the glucose levels.

[0044] Although as described above infusion pumps and continuous glucose monitors are separate devices, there are disadvantages to this configuration. For example, the requirement for Bluetooth or other wireless communications between the pump and the CGM require the devices to be paired. This requires the user to undertake a complex pairing procedure to pair the two devices and errors can arise if the devices become unpaired or communication issues arise between the devices. The CGM sensor and the pump also require two different attachment sites and separate insertions into the user’s body. In addition, the separate devices each require their own batteries, processors, communications devices and associated circuitry. Embodiments described herein integrate the CGM with the ambulatory infusion pump to address each of these disadvantages.

[0045] Referring to FIG. 5, an ambulatory infusion pump system 300 according to an embodiment of the disclosure is depicted. Ambulatory infusion pump system 300 is an integrated CGM and insulin pump system that can include a user-wearable infusion pump 302, a pump holder or tray 304 and a CGM sensor 306. Pump holder 304 is also depicted in Figure 6. Pump holder 304 can include a tray body 310 attached to an adhesive patch 312 that can releasably attach the pump holder 304 to a body of a user. A patch liner 314 comprising one or more pieces can include tabs 316 for removing patch liner 314 to expose the adhesive underside of adhesive patch 312 for attachment to the user. Tray body 310 can include a number of features related to guiding and releasably retaining an infusion pump on tray body 310, which are not described in detail herein. Further details regarding such features can be found in U.S Patent Publication Nos. 2024 / 0050650 and 2024 / 0226423, each of which is hereby incorporated herein by reference. Pump holder 304 can include a sensor recess 318 defined through a base surface 320 of tray body 310 sized and shaped to receive a CGM sensor such as sensor 306. In the depicted embodiment, the sensor recess 318 is configured such a top surface of the sensor 306 is flush with the base surface 320 of the tray body 310 to provide one continuous, flat surface on which the pump 302 will rest. The size and shape of sensor recess 318 can vary based on the configuration of a particular sensor. The location of sensor recess 318 on base surface 320 is selected to provide alignment of CGM sensor 306 with the pump 302 for optimal power and / or data transfer between CGM sensor 306 and pump 302. A wire aperture 322 can also be provided through adhesive patch 312 within sensor recess 318 to enable insertion of a sensor probe of the CGM sensor 306 through the pump holder 304 and into the user’s body.

[0046] A CGM sensor 306 that can be used with a system 300 as disclosed herein is depicted in Figures 7A-7B herein. CGM sensor 306 can include sensor housing 330 with a sensor probe 332 extending from the housing that is configured to be inserted into the body of the user. Housing 300 may include a top cover 334, which includes the upper surface 335 that rests flush with base surface 320 of tray body 310 when the sensor 306 is inserted into the sensor recess 318, and a bottom cover 336 defining an opening therebetween in which a Printed Circuit Board Assembly (PCBA) 338 is housed. PCBA 338 can include a probe attachment 340 to which the probe 332 is attached and which can have one or more electrical contacts 342 that interface with the probe 332. PCBA 338 can also have an inductive power receiving coil 344 mounted thereon. This inductive power receiving coil 344 replaces the much larger battery traditionally used in similar CGM sensors, which significantly reduces the size and profile of the CGM sensor. This smaller form factor enables the pump holder 304 to more readily accommodate the sensor 306 to enhance patient comfort and discretion.

[0047] Figure 8 depicts a portion of an ambulatory infusion pump 302 for use in an ambulatory infusion pump system 300 according to the disclosure. Ambulatory infusion pump 302 can include an inductive power transmitting coil 350 within a housing 352 of pump 302. In the depicted embodiment, inductive power transmitting coil 350 nests within a recess 354 defined in the housing 352. Additional circuitry would electrically couple the inductive power transmitting coil 350 with the electrical components of the pump 302, such as the battery and processor.

[0048] As can be seen in Figure 9, inductive power transmitting coil 350 can be positioned within housing 352 such that the transmitting coil 350 is aligned with the inductive power receiving coil 344 within the CGM sensor 306 when the sensor is inserted into the sensor recess 318 in the tray body 310 and the pump 302 is attached to the pump holder 304.

[0049] In embodiments disclosed herein, a CGM sensor 306 is therefore powered by an inductive power coil receiver 344 that is energized by an inductive power coil transmitter 350 embedded in an insulin pump 302 that receives power from the internal battery in the pump 302. This eliminates the need for a traditional battery within the CGM sensor, reducing its size and cost. Elimination of the battery further eliminates the need for replacing the battery in the sensor, simplifying device maintenance and enhancing reliability since there will be no gaps in sensor readings due to a dead battery.

[0050] The insulin pump 302 and CGM sensor 306 are both housed within the tray 310 of the pump holder in a manner that ensures power transfer between the pump and the sensor while maintaining a sleek, unified appearance on the body. This reduces the number of visible devices on the body, providing a more discreet and visually appealing system.

[0051] In these embodiments, communications between the CGM sensor and pump can also be accomplished via the corresponding inductive coils. Pump can include internal circuitry to transmit the signals measured by the CGM sensor to the pump processor. The processor of pump can include programming sufficient to receive the CGM signals and to process those signals for use of the glucose levels indicated by the signals in providing therapy with the pump. In such embodiments, no Bluetooth or other wireless communications between the devices is required because the CGM signals are sent to the pump utilizing the inductive charging coil already present in the pump. As such, the CGM does not require a complex pairing procedure and wireless connectivity issues preventing transmission of CGM data will not occur. There are therefore further cost savings in the system because the CGM also does not need a processor, wireless communications elements and associated circuitry. The battery life of the pump will also be enhanced due to reduced power consumption from not having continual wireless communications with the CGM, because the power consumption of providing power to the CGM is significantly lower that the power required for wireless communications with the CGM. In some embodiments, data obtained by the CGM sensor can be stored within a memory of the pump. This data could then be periodically synced to a smartphone application, the cloud or another external source to which the pump can periodically be connected. This can enhance data accessibility and historical data tracking, analysis and trends for patients and / or healthcare providers.

[0052] Referring to FIG. 10, an ambulatory infusion pump system 400 according to an embodiment of the disclosure is depicted. Ambulatory infusion pump system 400 is an integrated CGM and insulin pump system that can include a user-wearable infusion pump 402, a pump holder or tray 404 and a CGM sensor 406. A power bridge attachment 408 facilitates the interconnection of the infusion pump 402 and the 4GM sensor, as will be described in more detail below.

[0053] Pump holder 404 is also depicted in Figure 11. Pump holder 404 can include a tray body 410 attached to an adhesive patch 412 that can releasably attach the pump holder 404 to a body of a user. A patch liner 414 comprising one or more pieces can include tabs 416 for removing patch liner 414 to expose the adhesive underside of adhesive patch 412 for attachment to the user. Tray body 410 can include a number of features related to guiding and releasably retaining an infusion pump on tray body 410, which are not described in detail herein. Further details regarding such features can be found in U.S Patent Publication Nos. 2024 / 0050650 and 2024 / 0226423, each of which is hereby incorporated herein by reference. Pump holder 404 can include a sensor recess 418 defined through a tray extension 420 extending outwardly from a perimeter of tray body 410 sized and shaped to receive a CGM sensor such as sensor 406. The size and shape of sensor recess 418 can vary based on the configuration of a particular sensor. Tray extension 420 can include one or more projections 422 configured to aid in retaining a CGM sensor in sensor recess 418. Pump holder 404 can further define a pair of latch apertures 424 in a retaining wall 426 of tray body 410 which aid in retaining the power bridge thereon.

[0054] A CGM sensor 406 that can be used with a system 400 as disclosed herein is depicted in Figure 12 herein. CGM sensor 406 can include a sensor housing 430 with a sensor probe 432 extending from the housing that is configured to be inserted into the body of the user. A sensor body 434 can include a plurality of electrical contacts 436. Although three electrical contacts 436 are depicted, greater or fewer electrical contacts can be employed. The particular geometries and size of sensor housing 430 and sensor body 434 are exemplary only and system can be adapted as needed for various other applications. In the depicted embodiment, sensor housing 430 includes a plurality of outwardly extending ledges 438 that interface with the projections 422 on the tray extension 420 of pump holder 404 to aid in retaining CGM sensor 404 in sensor recess 418.

[0055] Figure 13 depicts a portion of an ambulatory infusion pump 402 for use in an ambulatory infusion pump system 400 according to the disclosure. Ambulatory infusion pump 402 can include an electrical connector 450 on an exterior surface of a housing 452 of pump 402. In the depicted embodiment, electrical connector 450 comprises a plurality of spring-loaded pogo pins 454 (depicted as the female pogo connector). In various other embodiments, other known types of electrical connections can be employed. Additional circuitry can electrically couple the electrical connector 450 with the internal electrical components of the pump 402, such as the battery and processor.

[0056] Figure 14A-14B depict the power bridge 408 of ambulatory infusion pump system 400 that electrically connects the CGM sensor 406 with the pump 402. Power bridge 408 includes an electrical connector 470 that interfaces with electrical connector 450 on housing 452 of pump 402. In this embodiment, electrical connector 470 includes a plurality of pogo pins 472 (e.g., male connector) that mate with the pogo pins 454 on the electrical connector 450 on pump. Electrical connectors 450, 470 can further include complementary magnets that aid in maintaining the connectors together. Electrical connector 470 can be connected with a plurality of wires 474 to sensor interface 476. Sensor interface 476 can have a plurality of electrical contacts 478 that contact and electrically connect to electrical contacts 436 on CGM sensor 406. In the depicted embodiment, sensor interface 476 includes three electrical contacts 478 corresponding to the three electrical contacts 436 of CGM sensor 406, with a corresponding wire 474 for each, but greater or fewer electrical contacts and / or wires can be present. Power bridge 408 can further include a pair of latches 480 configured to provide a snap-fit with latch apertures 424 in pump holder 404 to releasably connect power bridge 408 to pump holder 404, but any other type of mechanical connection can alternatively be employed.

[0057] Figure 15 depicts the pump holder 404 of ambulatory infusion pump system 400 with the CGM sensor 406 and an infusion cannula 490 inserted through pump holder 404 (and into a user’s body). CGM sensor 406 nests within sensor aperture 418 of tray extension 420 with projections 422 on tray extension 420 interfacing with ledges 438 on the housing 430 of CGM sensor 406 to retain the CGM sensor 406 thereon. Pump 402 can then be releasably attached to the tray body 410 of pump holder 404 as shown in Figure 16A. Power bridge 408 is then slid over tray extension 420 and releasably attached to tray body 410 be inserting latches 480 of power bridge 408 into latch apertures 424 in retaining wall 426 of tray body 410 connected to tray extension as shown in Figures 16A-16C. In doing so, the electrical contacts 478 of sensor interface 476 of power bridge 408 are brought into contact with the electrical contacts 436 of CGM sensor 406 and the electrical connector 470 of power bridge 408 is mated with the electrical connector 450 on the outer housing 452 of the pump. The creates an electrical coupling from the CGM sensor 406 to the internal processor of the pump 402 via the sensor interface 476, corresponding electrical connectors 450, 470 in the power bridge 408 and pump 402 and internal circuitry in the pump 402.

[0058] In embodiments disclosed herein, a CGM sensor 406 is therefore powered through a direct electrical connection with an insulin pump 402 via power bridge 408 such that the CGM sensor receives power from the internal battery in the pump 402. This eliminates the need for a traditional battery within the CGM sensor, reducing its size and cost. Elimination of the battery further eliminates the need for replacing the battery in the sensor, simplifying device maintenance and enhancing reliability since there will be no gaps in sensor readings due to a dead battery. Power bridge 408 is particularly advantageous in providing an ability to provide a direct power connection between a CGM sensor and an insulin pump in a circumstance where the physical footprint and configuration of the CGM sensor makes it impractical to directly physically interface the CGM sensor with the pump.

[0059] The insulin pump 402 and CGM sensor 406 are both retained by the pump holder of the pump holder in a manner that ensures power transfer between the pump and the sensor while maintaining a sleek, unified appearance on the body. This reduces the number of separate devices on the body, providing a more discreet and visually appealing system.

[0060] In these embodiments, communications between the CGM sensor and pump can also be accomplished via the direct electrical connection facilitated by power bridge. Pump can include internal circuitry to transmit the signals measured by the CGM sensor to the pump processor. The processor of pump can include programming sufficient to receive the CGM signals and to process those signals for use of the glucose levels indicated by the signals in providing therapy with the pump. In such embodiments, no Bluetooth or other wireless communications between the devices is required because the CGM signals are sent to the pump utilizing the direct electrical connection between the CGM sensor and the pump. As such, the CGM does not require a complex pairing procedure and wireless connectivity issues preventing transmission of CGM data will not occur. There are therefore further cost savings in the system because the CGM also does not need a processor, wireless communications elements and associated circuitry. The battery life of the pump will also be enhanced due to reduced power consumption from not having continual wireless communications with the CGM, because the power consumption of providing power to the CGM is significantly lower that the power required for wireless communications with the CGM.

[0061] Referring to FIG. 17, an ambulatory infusion pump system 500 according to an embodiment of the disclosure is depicted. Ambulatory infusion pump system 500 is an integrated CGM and insulin pump system that can include a user-wearable infusion pump 502, a pump holder or tray 504 and a CGM sensor 506.

[0062] Pump holder 504 is also depicted in Figure 18. Pump holder 504 can include a tray body 510 attached to an adhesive patch 512 that can releasably attach the pump holder 504 to a body of a user. A patch liner 514 comprising one or more pieces can include tabs 516 for removing patch liner 514 to expose the adhesive underside of adhesive patch 512 for attachment to the user. Tray body 510 can include a number of features related to guiding and releasably retaining an infusion pump on tray body 510, which are not described in detail herein. Further details regarding such features can be found in U.S Patent Publication Nos. 2024 / 0050650 and 2024 / 0226423, each of which is hereby incorporated herein by reference. Pump holder 504 can include a sensor nest 518 defined on tray body 510 sized and shaped to receive a CGM sensor such as sensor 506. The size and shape of sensor nest 518 can vary based on the configuration of a particular sensor. In the depicted embodiment, sensor nest 518 comprises a pair of nest walls 520 that can include mechanical mating features configured to provide a snap-fit to releasably retain a CGM sensor therein. A probe aperture 522 between walls 520 enables insertion of a sensor probe of the CGM sensor through the pump holder 504 and into the user’s body. Tray body 510 can also include an infusion set nest 524 configured to releasably retain a cannula assembly for delivery of medicament to the user therein.

[0063] A CGM sensor 506 that can be used with a system 500 as disclosed herein is depicted in Figures 19A-19C. CGM sensor 506 can include a sensor body 530 with a sensor probe 532 extending from the body that is configured to be inserted into the body of the user. Sensor probe 532 can be electrically coupled within sensor body 530 to a plurality of electrical contacts 534 that can be exposed on an exterior of sensor body 530 to transmit electrical signals from the sensor probe 532. Although two electrical contacts 534 are depicted greater or fewer electrical contacts can be employed. In addition, although the electrical contacts 534 are depicted as being oriented vertically with respect to one another, other orientations are possible such as horizonal, coaxial, etc. The particular geometry and size of sensor body 530 is exemplary only and system can be adapted as needed for various other applications. In the depicted embodiment, sensor body 530 includes a retention slot 536 on each side of sensor body 530 that interface with retention features in sensor nest 518 of pump holder 504 to aid in retaining CGM sensor 504 in sensor nest 518.

[0064] Figure 20 depicts a portion of an ambulatory infusion pump 502 for use in an ambulatory infusion pump system 500 according to the disclosure. Ambulatory infusion pump 502 can include an electrical connector 550 on an exterior surface of a housing 552 of pump 502. In the depicted embodiment, electrical connector 550 comprises a pair of spring-loaded pogo pins 554. The pair of vertically oriented pins 554 correspond to the number and orientations of the electrical contacts 534 of CGM sensor 506 such that in embodiments in which CGM sensor has a different number, orientation, and / or configuration of electrical contacts, the electrical connector 550 on ambulatory infusion pump 502 can similarly be redesigned to interface with a given CGM sensor design. In various other embodiments, other known types of electrical connections can be employed. Additional circuitry would electrically couple the electrical connector 550 with the internal electrical components of the pump 502, such as the battery and processor.

[0065] Figure 21 depicts the pump holder 504 of ambulatory infusion pump system 500 with the CGM sensor 506 and an infusion cannula 590 inserted through pump holder 504 (and into a user’s body). CGM sensor 506 nests within sensor nest 518 of tray body 510 with the mating features of nest walls 520 providing a snap-fit with retention slots 536 in CGM sensor 506 to releasably retain the CGM sensor 506 within the sensor nest 518. Infusion cannula 590 is similarly releasably retained within the infusion set nest 524.

[0066] Ambulatory infusion pump 502 can then be releasably attached to the tray body 510 of pump holder 504 as shown in Figures 22A-22B. Figure 22A depicts the assembled system 500 and Figure 22B depicts the system with a cartridge of the ambulatory infusion pump 502 removed for sake of clarity. Sensor nest 518 is positioned on tray body 510 and is configured to retain CGM sensor 506 in manner such that when pump 502 is slid onto tray body 510, the pogo pins 554 (or other electrical contacts) of electrical connector 550 on pump housing 552 are brought into direct contact with the electrical contacts 534 of CGM sensor 506. The creates a direct electrical coupling from the CGM sensor 506 to the internal processor of the pump 502 via the electrical connectors 534, 550 of the CGM sensor 506 and pump 502 and internal circuitry in the pump 502.

[0067] In embodiments disclosed herein, a CGM sensor 506 is therefore powered through a direct electrical connection with an insulin pump 502 such that the CGM sensor receives power from the internal battery in the pump 502. This eliminates the need for a traditional battery within the CGM sensor, reducing its size and cost. Elimination of the battery further eliminates the need for replacing the battery in the sensor, simplifying device maintenance and enhancing reliability since there will be no gaps in sensor readings due to a dead battery.

[0068] The insulin pump 502 and CGM sensor 506 are both housed within the tray 510 of the pump holder in a manner that ensures power transfer between the pump and the sensor while maintaining a sleek, unified appearance on the body. This reduces the number of visible devices on the body, providing a more discreet and visually appealing system.

[0069] In these embodiments, communications between the CGM sensor and pump can also be accomplished via the direct electrical connection. Pump can include internal circuitry to transmit the signals measured by the CGM sensor to the pump processor. The processor of pump can include programming sufficient to receive the CGM signals and to process those signals for use of the glucose levels indicated by the signals in providing therapy with the pump. In such embodiments, no Bluetooth or other wireless communications between the devices is required because the CGM signals are sent to the pump utilizing the direct electrical connection between the CGM sensor and the pump. As such, the CGM does not require a complex pairing procedure and wireless connectivity issues preventing transmission of CGM data will not occur. There are therefore further cost savings in the system because the CGM also does not need a processor, wireless communications elements and associated circuitry. The battery life of the pump will also be enhanced due to reduced power consumption from not having continual wireless communications with the CGM, because the power consumption of providing power to the CGM is significantly lower that the power required for wireless communications with the CGM.

[0070] In some embodiments, data obtained by the CGM sensor can be stored within a memory of the pump. This data could then be periodically synced to a smartphone application, the cloud or another external source to which the pump can periodically be connected. This can enhance data accessibility and historical data tracking, analysis and trends for patients and / or healthcare providers.

[0071] In embodiments, the pump will be able to determine if the connection with the CGM sensor has been disconnected because the pump will no longer be receiving data from the CGM and / or if the CGM loses power. In such circumstances, the pump can provide an alert informing the user that the CGM has become disconnected and / or has low or no power.

[0072] In some embodiments, the system can include a dual-purpose inserter (not pictured) to optionally allow for simultaneous insertion of both the CGM sensor and the insulin cannula for the pump into the body. This can simplify the insertion process for patients. Separate inserters can also be used. This may be beneficial in situations where the CGM sensor needs to be replaced more frequently than the cannula, or vice versa.
