Abstract: A TETS having an external controller having a power source, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and an implantable blood pump. The implantable controller has a battery configured to receive power from the receiving coil and the external controller is configured to categorize power transfer states based on predetermined thresholds of efficiency and power demand, and user display states (associated with optional configurable notifications) based on the power transfer states and predetermined temperature thresholds of the transmission coil.

Abstract: A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.

Abstract: A method includes detecting, by an implantable medical device (IMD), attachment to the IMD of at least one implantable medical lead with at least one electrode; and triggering by the IMD, based on the detecting of the attachment to the IMD of the at least one medical lead, a device test sequence in which the IMD performs the following qualification tests over an evaluation period: detecting an impedance for at least one electrical path that includes the at least one electrode to determine a connection status of the IMD to the at least one electrode; and comparing EGM (electrogram) amplitudes of the patient over an EGM test period against a predetermined threshold.

Abstract: A high contrast instrument, such as a radiopaque portion, can be captured and/or viewed in an image that is acquired with an imaging system, such as with a fluoroscopic imaging system. A statistical model can be used to assist in identifying a possible or probable location of a target. A user may move the instrument coil to the statistically probable location of the target to, for example, perform a procedure or carry out a task.

Abstract: Systems, apparatus, methods and computer-readable storage media facilitating management of operation of an implantable medical device (“IMD”) using a number of communication modes are provided. An IMD is configured to operate in a disabled mode wherein radio frequency (RF) telemetry communication is disabled, or operate in a first advertising mode using the RF telemetry communication. The IMD receives a clinician session request from a clinician device via an induction telemetry protocol while operating in the disabled mode or the first advertising mode, and transitions to operating from the disabled mode or the first advertising mode to operating in a second advertising mode based on receiving the clinician session request. From the second advertising mode, the IMD can establish a clinician telemetry session with the clinician device using the RF telemetry communication and a unique security mechanism facilitated by an identifier for the clinician device included in the clinician session request.

Abstract: A system for minimizing misalignment notifications for a TETS having an implantable blood pump, an external controller having a power source and a processing circuitry, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and the implantable blood pump. The implantable controller having a power source configured to receive power from the receiving coil. The processing circuitry may be configured to: operate in a first mode where an alert is generated when a power efficiency transfer between the transmission coil and the receiving coil is below a first predetermined threshold; and operate in a second mode where the alert is only generated when the power remaining in the power source for the implantable controller is below a first predetermined power source threshold.

Abstract: An internal controller implantable within the body of a patient as part of a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, the internal controller includes processing circuitry configured to establish a radio frequency (RF) communication session with a first external power transmitter that responds to the advertisement. The processing circuitry is also configured to determine when a power transmission status of the first external power transmitter does not match a power receipt status of the internal controller, and then terminate the RF communication session with the first external power transmitter and cause the radio interface to broadcast another advertisement.

Abstract: Systems, apparatus, methods and non-transitory computer readable media facilitating telemetry data communication security between an implantable device and an external clinician device are provided. An implantable device can include a security component configured to generate security information based on reception of a clinician telemetry session request from the clinician device via a first telemetry communication protocol. The security information can include a session identifier and a first session key, and the clinician telemetry session request can include a clinician device identifier associated with the clinician device. The implantable device can further include a communication component configured to establish a clinician telemetry session with the clinician device using a second telemetry communication protocol based on determining that a connection request, received via the second telemetry communication protocol, was transmitted by the clinician device based on inclusion of the clinician device in the connection request.
