摘要： 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.

摘要： Methods, systems, and apparatus for powering and/or recharging medical devices implanted within the body are described. An illustrative implantable medical device includes a housing having an internal cavity and a flexible anchor assembly that is coupled to the housing. The flexible anchor assembly includes a first electrical conductor, a second electrical conductor, and a piezoelectric layer that is disposed between the first and second electrical conductors and that is configured to displace in response to a physiologic force applied to the flexible anchor assembly and generate a voltage differential between the first and second electrical conductors. The implantable medical device includes power circuitry that converts the voltage differential between the first and second electrical conductors into an operating current for powering one or more components within the implantable medical device and/or for recharging a rechargeable power supply within the device.

摘要： A neurostimulation system senses a signal indicative of a patient's physical state such as posture and/or activity level. In various embodiments, a stored value for each of stimulation parameters controlling delivery of neurostimulation is selected according to the patient's physical state. In various embodiments, values of the stimulation parameters are approximately optimized for each of a number of different physical states, and are stored for later selection.

摘要： An apparatus comprises an implantable medical device that includes a storage circuit. The storage circuit includes a first stage circuit configured to receive an input signal and to invert and store information about a data bit received in the input signal, a second stage circuit coupled to the output of the first stage circuit to invert and store information about a data bit received from the first stage circuit, and an error circuit coupled to the output of the first stage circuit and an output of the second stage circuit. The error circuit generates an error indication when the storage circuit outputs match while the first stage circuit and the second stage circuit are in an inactive state.
