    摘要: There is provided an implantable pressure monitor having a fluid sack in contact with a body part of a patient where the fluid sack is retained to the body part by a pressure monitor housing that may have various attachment means. The fluid sack is filled with a liquid such as silicone oil. The pressure monitor housing has an opening that provides access to a fistula with a fluid valve that terminates through the fluid sack. A fiber optic pressure sensor is in contact with the liquid in the fluid sack by way of the fistula and fluid valve. In some embodiments of the present invention, an electronics module is incorporated with the implantable pressure monitor to provide telemetry, power, and the like.

    摘要: Techniques for determining an attachment stability of leadless pacing device (LPD) implanted within a patient are described. For example, the LPD may detect one or more stability metrics from one or more electrodes of the LPD and/or an activity sensor within the LPD. Based on one or more of these stability metrics, e.g., a mechanical motion of the LPD, a stability module within the LPD may determine the attachment stability of the LPD within the patient. If the attachment stability is insufficient to provide efficacious therapy or indicates at least partial dislodgement of the LPD from tissue, the LPD may wirelessly transmit stability information to an external device. In some examples, the LPD may be implanted within a chamber of the heart.

    摘要: A system and surgical procedure for monitoring physiological parameters within an internal organ of a living body. The procedure entails making a first incision to expose the organ and a second incision through an external wall of the organ and into an internal cavity. A sensing unit is placed in the second incision such that a proximal end thereof remains outside the organ. The unit includes a sensing device having a sensing element for sensing the physiological parameter within the organ, and an anchor to which the sensing device is secured. The unit occludes the second incision and a distal end of the unit does not extend more than one centimeter into the cavity. The anchor is then secured to the wall of the organ, after which the first incision is closed and a readout device telemetrically communicates with the sensing device to obtain a reading of the physiological parameter.

    摘要: A miniature resonating marker assembly that includes, in one embodiment, a ferromagnetic core, a wire coil disposed around the core, and a capacitor connected to the wire coil adjacent to the magnetic core. The core, coil, and capacitor form a signal element that, when energized, generates a magnetic field at a selected resonant frequency. The magnetic field has a magnetic center point positioned along at least one axis of the signal element. An inert encapsulation member encapsulates the signal element therein and defines a geometric shape of the resonating marker assembly. The geometric shape has a geometric center point substantially coincident with the magnetic center point along at least a first axis of the signal element. The shape and configuration of the assembly also provides for a miniature signal element specifically tuned to resonate at a selected frequency with a high quality factor.
