摘要： Reservoir volume of implantable infusion devices may be determined using a volume sensor that provides a signal representative of a distance between the volume sensor and a movable wall of the reservoir. The volume sensor may be a light-based or sound-based sensor, and may be located outside of the reservoir.

摘要： Implantable medical devices have modular lead bores that are constructed from individual lead bore modules. A given modular lead bore utilizes the number of individual lead bore modules necessary for the particular implantable medical device. Each lead bore module has a lead bore passageway and a feedthrough passageway. An electrical contact is present within the lead bore passageway of each lead bore module and the electrical contact is aligned to the lead bore passageway of a lead bore module. Hermetic feedthrough assemblies are also present within the lead bore passageway of each lead bore module. A feedthrough pin passes through a hermetic feedthrough assembly within a feedthrough passageway of each lead bore module. Each feedthrough pin is electrically coupled to a corresponding electrical contact and the medical device circuitry.

摘要： In some examples, an implantable medical device (IMD) including a hermetically sealed housing that is configured to enclose internal components. The internal components may include stimulation circuitry, processing circuitry configured to control the stimulation circuitry to deliver electrical stimulation using one or more leads received by the housing, telemetry circuitry, and a rechargeable power source. The IMD may also include a coil configured to at least one of receive energy to recharge the rechargeable power source or receive and/or transmit signals for wireless telemetry with another device, wherein the implantable medical device is configured to mount to a cranium of a patient, and wherein the coil is coiled about an axis that is approximately orthogonal to a major surface of the IMD.

摘要： An implantable infusion device includes a reservoir for housing an infusion medium and a drive mechanism having an inlet chamber, a piston and a piston channel. The inlet chamber is in fluid communication with the reservoir. The piston channel is in fluid communication with the inlet chamber, and has a distal end and a proximal end, the proximal end being closer to the inlet channel than the distal end. The piston is axially moveable within the piston channel to drive infusion medium out of the distal end of the piston channel. The clearance between the piston and the channel is sufficiently small to prevent undissolved gas in the inlet chamber from passing through the clearance. The inlet chamber may be sufficiently large to allow undissolved gas to accumulate without adversely affecting the performance of the infusion device.

摘要： An implantable medical device (IMD) includes a housing that is configured to enclose internal components including at least a processor and a power source. The housing defines two major surfaces that are generally parallel to each other and one or more channels that are each configured to receive a lead and electrically couple the respective lead to the internal components, where each of the channels extend substantially straight in to the housing along an axis generally parallel to the two major surfaces. The housing may be configured to be mounted to a cranium of a patient such that at least one of the two major surfaces approximates a curvature of the cranium. The IMD may include one or more funneling walls that define a rounded and smooth transition from a sidewall of the housing to a surface that defines one or more mouths to the channels.
