  • Patent number: 9980673
    Abstract: A handheld, conforming capacitive sensing apparatus configured to measure Sub-Epidermal Moisture (SEM) as a mean to detect and monitor the formation of pressure ulcers. The device incorporates an array of electrodes which are excited to measure and scan SEM in a programmable and multiplexed manner by a battery-less RF-powered chip. The scanning operation is initiated by an interrogator which excites a coil embedded in the apparatus and provides the needed energy burst to support the scanning/reading operation. Each electrode measures the equivalent sub-epidermal capacitance corresponding and representing the moisture content.

  • Publication number: 20170265984
    Abstract: Devices and methods are disclosed for providing access to a central compartment of a hip joint. The devices can access the central compartment by distracting all or a portion of the labrum. The labrum can be distracted by advancing a device underneath the bottom edge of the labrum, and using the device to further distract the labrum. Some devices can move underneath the labrum to provide a gap for other devices to access the central compartment.

  • Publication number: 20160235443
    Abstract: A method for creating space in a joint formed at the convergence of two bones, the method comprising: applying force to a body part so as to separate the two bones from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state, whereby to distract the joint and create an intrajoint space; inserting an assembly of three balloons into the intrajoint space while the assembly of three balloons is in a contracted condition; expanding the assembly of three balloons within the intrajoint space; and reducing the force applied to the body part so that the joint is supported on the assembly of three balloons, with the two bones remaining separated from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state.
