Abstract: An implantable medical device includes a coil which is configured for transmission and/or reception of RF fields for communication with external devices. The coil has a conductor that is wound around a core. The core is adapted to saturate in the presence of a static magnetic field or a B0-field generated by an MRI machine thereby reducing the voltage induced in the coil by an RF field and/or by a gradient field generated by the MRI machine.

Abstract: A system and method for installing/implanting a leadless implant can include a leadless implant with shortened tine-based anchors and an implantation tool with a modified tip. The tines can extend from a surface of the leadless implant and may include a preformed curve or other shape to enable the tine to hook into or grapple tissue. The implantation tool may be provided with a modified tip to assist with proper alignment, insertion, and anchoring of the shortened tines. A tip of the implantation tool can have a reduced inner diameter to cause the tine tips to be approximately normal to the surface of the tissue to which the implant is being anchored. Upon deployment of the leadless implant, the tines of the anchoring mechanism are appropriately aligned for proper insertion so that robust anchoring is achieved.

Abstract: System, method, and tool for implanting an electrode cuff. The system can include a cuff and a slider implement, where the cuff is temporarily retained within and/or onto the slider implement by a retainer mechanism during implantation. The cuff can be structured to exhibit a natural rolled shape, but can be resiliently bendable so as to flex from the rolled shape while having a tendency to move back to the rolled shape. The cuff can be releasably secured to a portion of the slider implement, which may include holding the cuff in an unrolled shape. The cuff can then be positioned adjacent the nerve. The retainer mechanism can then be actuated to allow the cuff to advance towards its naturally rolled shape, thereby wrapping around the nerve.

Abstract: An implantable medical device including a data communication interface connected to a pulse generator. The pulse generator generates and delivers forward current pulses and reverse current pulses, wherein a polarity of the reverse current pulses is opposite to the polarity of the forward current pulses. Generates pulses representing binary digits, wherein a first kind of digits (1 or 0) is represented by a current pulse, and a second kind of digit respective of the other type of binary digits (0 or 1) is represented by a pause between current pulses. The data communication interface together with the pulse generator deliver current pulses with strictly alternating polarity such that every other current pulse is a reverse current pulse of opposite polarity compared to an immediately preceding forward current pulse. Thus, every string of current pulse is both, charge balancing and information encoding.

The inner packaging includes at least two electric contacts, wherein each of the at least two electric contacts of the inner packaging matches one of the at least two electric feedthroughs of the outer packaging to provide an electric connection between a respective feedthrough and the corresponding contact when the inner and the outer packaging are closed. Each of the contacts of the inner packaging feed electrical charge from outside of the inner packaging to the inside of the inner packaging and vice versa. The inner packaging includes electrically conducting media that allows propagation of electrical charge between the contacts of the inner packaging and an implantable medical device included inside in a packaging when the containment is filled.

Abstract: A method for determining if an implantable medical device (IMD) in a patient is magnetic resonance conditional. Embodiments include a Home Monitoring Service Center (HMSC) that indicates if the IMD is MR conditional and what those conditions are. The IMD includes memory with flags, enabling a physician to set a flag to “MR conditional” if the IMD is MR conditional, if there are no abandoned leads in the patient, and if there are no other hardware in the patient that are not MR conditionally approved. In embodiments, the flags indicate safe for 1.5 T, 3.0 T, 1.5 & 3.0 T, up to 2 W/Kg, up to 4 W/Kg, with/without exclusion zone, and date flags are set. During home monitoring, the HMSC reads out a status of the MR conditional flags and the date last confirmed. If the patient needs an MRI scan, physician queries HMSC to determine MR conditional status.

Abstract: A method for creating a subcutaneous implant pocket and implanting an implantable medical device therein, as well as an implantation kit that may be used in accordance with the method, are disclosed. The implantation kit includes an implantable medical device, a tunneling device, and an insertion tool.

Abstract: One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device (“IMD”), an external computing device, and a backend computing system. The IMD determines a physiologic parameter value within a patient's body, and communicates the physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device receives the physiologic parameter from the IMD and communicates it to the backend computing system. The backend computing system receives the physiologic parameter value and obtains an ambient condition value outside the body.
