摘要:
A sensing device may include a housing and one or more features configured to couple the housing against the outer surface of the bone of the patient. A sensing device may include onboard electronics carried by the housing, the onboard electronics comprising: communication circuitry, one or more sensors configured to generate data regarding one or more characteristics of the patient; and processing circuitry configured to activate the communication circuitry to send the generated data to a device outside the patient.

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.

Methods, apparatus and systems for enhancing cardiac pacing generally provide for measuring at least one cardiac characteristic, calculating at least one cardiac performance parameter based on the measured characteristic(s), and adjusting at least one functional parameter of a cardiac pacing device. Devices may include at least one catheter (such as a multiplexed catheter with one or more sensors and/or actuators), at least one implant (such as a sensor implantable in a heart wall), or a combination of both. Various cardiac performance parameters and/or pacing device performance parameters may be weighted, and the parameters and their respective weights may be used to determine one or more adjustments to be made to the pacing device. In some instances, the adjustments are made automatically.

An eye implant has a body including (a) a receiver, (b) a first mounting clip and (c) a second mounting clip. The receiver is adapted to hold an intraocular device to be implanted in an eye. The receiver, the first mounting clip and the second mounting clip generally extend along a common arc.

A sensor implantation assembly is disclosed that includes a tissue puncture closure device. The tissue puncture closure device has a proximal end portion and a distal end portion and a suture extending from the proximal end portion to the distal end portion. A suture anchor assembly is also included that is insertable through a tissue wall puncture. The suture anchor assembly is attached to the suture at the distal end portion of the closure device and has a diagnostic sensor. A sealing pad is positioned around the suture at the distal end portion and is slidable along the suture. The diagnostic sensor may be placed within a tissue wall to gather diagnostic information such as pressure measurements at or near the site of the tissue puncture closure.

摘要:
A system that remotely measures displacement between two objects. A passive sensor is affixed to each object, such that the sensors are substantially parallel. Each sensor has a permeable rod, a surrounding coil, and a tuning capacitor, and have substantially the same resonant frequency. When an interrogating device is placed near the sensors, the frequency responses of the sensors indicates their relative displacement and thus the displacement between the objects.

Described herein are flexible and stretchable LED arrays and methods utilizing flexible and stretchable LED arrays. Assembly of flexible LED arrays alongside flexible plasmonic crystals is useful for construction of fluid monitors, permitting sensitive detection of fluid refractive index and composition. Co-integration of flexible LED arrays with flexible photodetector arrays is useful for construction of flexible proximity sensors. Application of stretchable LED arrays onto flexible threads as light emitting sutures provides novel means for performing radiation therapy on wounds.
