An implantable device including a housing, circuitry within the housing, and a power source attached to the housing and electrically connected to the circuitry. The device may include electrically conductive connectors configured to electrically connect positive and negative terminals of the power source to the circuitry. The device may include a power source terminal enclosure attached to the power source and configured to enclose the positive and negative terminals of the power source. The power source terminal enclosure may include holes through which the electrically conductive connectors pass. The device may include a housing cap enclosure attached to the power source terminal enclosure and to an open end of the housing. The housing cap enclosure may enclose the circuitry within the housing and includes passages through which the electrically conductive connectors pass.

An insertion tool for creating a subcutaneous pocket and implanting a device in the pocket. The tool may include a cannula extending from a handle, a dissector tip disposed at a distal end of the cannula, and a rod. The cannula and dissector tip may create the pocket. The cannula may include a passage and an opening into the passage, and the cannula may be disposed in the passage and move along the passage between a retracted position and an extended position. The rod and the cannula may be configured such that, when the rod is at the retracted position, the cannula holds the device in the passage, and as the cannula moves from the extended position to the retracted position, the rod forces the device through the opening at the distal end of the cannula, at least partially out of the cannula, and at least partially into the pocket.

A removal tool uses magnetic attraction to guide the removal tool toward an implantable device subcutaneously implanted in subcutaneous tissue of a host and to remove the implantable device from the host. The removal tool may include first and second lever members that are pivotably connected together, and the first and second lever members include a pair of jaw members configured to move between open and closed positions to grasp the implantable device. The first jaw member may include a magnet to magnetically attract and couple to an implantable device implanted subcutaneously below a skin surface of a host.

A sensor that may be used to detect the presence, amount, and/or concentration of an analyte in a medium within an animal. The sensor may include a sensor housing, an indicator element embedded within and/or covering at least a portion of the sensor housing, and a membrane over the indicator element. The sensor may include one or more of a first coating on an inner surface of the membrane, a second coating on an outer surface of the membrane, and a layer on the outside of the indicator element. One or more of the first coating, second coating, and layer may reduce deterioration of the indicator element by catalyzing degradation of reactive oxygen species (ROS). The one or more coatings on the membrane may increase the light blocking capability of the membrane, which may improve the accuracy of the sensor.

In one aspect, a tunneling tool for creating a subcutaneous pocket below a skin surface is provided. The tunneling tool may include a handle, a rod, a first prong, and a second prong. The rod and the first and second prongs may extend from a first end of the handle. The rod may extend farther from the first end of the handle than the first and second prongs and be configured to create the subcutaneous pocket. The first and second prongs may be configured to limit the depth at which the rod is capable of creating the subcutaneous pocket. The first and second prong may comprise first and second length indicators, respectively, configured to indicate a length of the subcutaneous pocket formed by the rod. In another aspect, a method of creating a subcutaneous pocket using the tunneling tool is provided.
