  • Patent number: 10220215
    Abstract: An Implantable Medical Device (IMD) is disclosed having a bi-directional short-range far-field Radio-Frequency (RF) data antenna, operable in accordance with a short-range RF standard such as Bluetooth for example. The antenna is neither located inside the conductive case of the IMD, nor in the non-conductive header of the IMD that includes the lead connectors. Instead, the antenna is outside of the case, proximate to and generally planar with a flat planar side of the case that faces outward of the patient when the IMD is implanted. Dielectric materials keep the antenna from shorting to the case and to the patient's tissue. Because the antenna is not located within the conductive case, data communications to and from the antenna are less subject to attenuation. Not locating the antenna in the header reserves room for the header's lead connectors, thus simplifying IMD design.

  • Patent number: 9931514
    Abstract: A hermetically sealed filtered feedthrough assembly for an active implantable medical device includes an electrically conductive ferrule hermetically sealed by a first braze to an insulator. A conductor is hermetically sealed to and disposed through the insulator. A filter capacitor has an active electrode plate and a ground electrode plate which are disposed within and supported by a capacitor dielectric in an interleaved, partially overlapping relationship. A first passageway is disposed through the capacitor dielectric having a capacitor internal metallization which is connected to the active electrode plate. A capacitor external metallization electrically connects to the ground electrode plate. An oxide-resistant metal addition includes a conductive core with a conductive cladding of a different material. A first electrical connection is between the oxide-resistant metal addition and the capacitor external metallization.

  • Patent number: 9844659
    Abstract: Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

  • Patent number: 9837704
    Abstract: A flexible antenna is associated with an active implantable medical device to facilitate communication between the implantable medical device and an external component in the outside world via, for example, long range or far field telemetry. The flexibility of the antenna allows it to conform to the shape of the location at which it is situated, such as on the cranial bone of a patient for an antenna associated with a cranially implanted medical device. The conformability of the antenna helps to maintain the antenna in the desired shape and to maintain it in the desired location relative to implantable medical device and the patient and improves patient comfort.

  • Patent number: 9802054
    Abstract: A leadless cardiac pacemaker is provided which can include any number of features. In one embodiment, the pacemaker can include a tip electrode, pacing electronics disposed on a p-type substrate in an electronics housing, the pacing electronics being electrically connected to the tip electrode, an energy source disposed in a cell housing, the energy source comprising a negative terminal electrically connected to the cell housing and a positive terminal electrically connected to the pacing electronics, wherein the pacing electronics are configured to drive the tip electrode negative with respect to the cell housing during a stimulation pulse. The pacemaker advantageously allows p-type pacing electronics to drive a tip electrode negative with respect to the can electrode when the can electrode is directly connected to a negative terminal of the cell. Methods of use are also provided.
