  • Publication number: 20090228078
    Abstract: Various implantable medical device embodiments stimulate an autonomic neural target from within a pulmonary artery, and comprise at least one electrode, a power supply, a neural stimulator connected to the power supply, and an anchor structure. The neural stimulator is configured to generate a neural stimulation signal for delivery to the neural stimulation target through the at least one electrode. The anchor structure is configured to chronically and securely implant the neural stimulator, the power supply and the at least one electrode within the pulmonary artery. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery. In various embodiments, the neural stimulator is configured to be operational to implement a neural stimulation protocol when chronically implanted within the pulmonary artery without a wired connection through the pulmonary valve.

  • Publication number: 20090093729
    Abstract: Embodiments of the invention are related to devices and methods for measuring arterial elasticity and/or blood pressure, amongst other things. In an embodiment, the invention includes an implantable medical device having a sensor element that is configured to engage a vessel of a patient. The sensor element is further configured to generate a signal in response to bending of the sensor element, where bending occurs as a result of changes in the pressure within the vessel. The implantable medical device further includes a controller in signal communication with the sensor element, where the controller is configured to store information regarding the signal generated by the sensor element. Other embodiments are also included herein.

  • Publication number: 20080021509
    Abstract: An implantable medical device comprising a housing and an ultrasonic transducer having a communication frequency coupled to a portion of the housing. The housing resonates at the communication frequency, and a casing is coupled to the housing and disposed over the ultrasonic transducer. The casing is adapted to amplify the deformation of the ultrasonic transducer in a bending mode and transfer the bending moment to the housing. An implantable medical device comprising a housing having an upper portion and a lower portion. A first ultrasonic transducer is coupled to a first connection rod and is coaxial with the first connection rod. The first ultrasonic transducer and first connection rod are interposed between the upper and lower portions such that the first ultrasonic transducer is adapted to vibrate the upper and lower portions simultaneously. A method of optimizing an ultrasonic transducer and a housing of an implantable medical device.
