  • Publication number: 20160220172
    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: 20160015319
    Abstract: A monitoring apparatus for a human body includes a node network with at least one motion sensor and at least one acoustic sensor. A processor is coupled to the node network, and receives motion information and acoustic information from the node network. The processor determines from the motion information and the acoustic information a source of acoustic emissions within the human body by analyzing the acoustic information in the time domain to identify an event envelope representing an acoustic event, determining a feature vector related to the event envelope, calculating a distance between the feature vector and each of a set of predetermined event silhouettes, and identifying one of the predetermined event silhouettes for which the distance is a minimum.

  • Patent number: 9186181
    Abstract: A method for creating space in a joint formed at the convergence of two bones, 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 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.

  • Publication number: 20150313703
    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: 20150250445
    Abstract: A multi-sensor wireless abdominal monitoring system comprising a low-profile belt that fits around the abdomen and is embedded with specialized wireless sensors. The system is configured to continuously monitor a range of gastrointestinal and abdominal wall functions. The system wirelessly transmits data to an external device, such as a smartphone or computer for storage and download to a central server. The acquired data may be monitored remotely through specialized software that generates clinically interpretable information presented through a graphical user interface. The device provides data that are immediately actionable for a wide range of inpatients and outpatients with high prevalence disorders in varied clinical settings.
