  • Publication number: 20200129763
    Abstract: A biostimulator, such as a leadless cardiac pacemaker, including an electrical feedthrough assembly mounted on a housing, is described. An electronics compartment of the housing can contain an electronics assembly to generate a pacing impulse, and the electrical feedthrough assembly can include an electrode tip to deliver the pacing impulse to a target tissue. A monolithically formed electrode body can have a pin integrated with a cup. The pin can be electrically connected to the electronics assembly, and the cup can be electrically connected to the electrode tip. Accordingly, the biostimulator can transmit the pacing impulse through the monolithic pin and cup to the target tissue. The cup can hold a filler having a therapeutic agent for delivery to the target tissue and may include retention elements for maintaining the filler at a predetermined location within the cup.

  • Publication number: 20200101300
    Abstract: Devices and methods are provided for a leadless implantable medical device (LIMD) comprising a housing. An electrode is disposed on the housing. An electronics circuit is disposed in the housing and is configured to sense cardiac signals, and/or generate and deliver pacing signals to the electrode. A transceiver circuit is disposed in the housing, and is configured to communicate wirelessly with an external device. A fixation antenna electrically separate from the electrode is disposed on a distal portion of the housing and is electrically coupled to the transceiver circuit, and configured to operate as an antenna for communication between the transceiver circuit and the external device.

  • Patent number: 9431694
    Abstract: A dual band antenna mounted to a case of an implantable medical device (IMD) for implant within a patient is provided. The dual band antenna includes a first antenna sub-structure (FAS) and a second antenna sub-structure (SAS) each separately tuned to match a corresponding first and second resonant frequency, by adjusting at least one of relative lengths of the FAS and SAS, a capacitance of the FAS, a location of the SAS relative to the FAS and a cross-sectional area of conducting elements forming the components of the antenna. The FAS is formed as an inverted E-shaped antenna having three branches. The first branch of the antenna is capacitive, a second branch provides a radio frequency signal feed and a third branch provides a shunt to ground. The SAS is formed as a mono-pole antenna that is formed integral with, and extends from, the FAS.
