  • 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.

  • Patent number: 9610454
    Abstract: In accordance with one embodiment, a leadless implantable medical device (LIMD), compromises a hermetic housing that has a distal portion and proximal portion. An electrode is proximate to the distal portion. An electronics package is disposed in the housing, in which the electronics package is configured to generate and deliver stimulation signals to the electrode. A fixation mechanism is disposed on the distal portion of the housing. A torque mechanism is disposed on the proximal portion of the housing. The torque mechanism has a tool engagement element movably coupled to the housing. The tool engagement element has a rotational force applied thereto during implant. The torque mechanism includes a torque limiter that maintains a fixed relation between the tool engagement element and the housing when in an engaged state. The torque limiter changes from the engaged state to a disengaged state when the rotational force exceeds a predetermined torque limit.

  • Publication number: 20130289637
    Abstract: The implantable medical device includes high-voltage components (such as defibrillation shock generation components) operative to generate high-voltage pulses for delivery to tissues of the patient while using the case or housing of the device as a stimulation electrode. The device also includes low-voltage Medical Implant Communication Service (MICS) or Medical Device Radiocommunications Service (MedRadio) components operative to generate low-power signals for communicating with an external device via radio frequencies while using the case as part of an antenna. A conductive noise shield is mounted within the case of the device and interposed between the high-voltage components and the case, with the shield configured to attenuate electrical interference between the high-voltage components and the case to facilitate radio-frequency communication between the low-voltage MICS/MedRadio components and the external device, which use the case as part of the antenna.
