  • Publication number: 20210128091
    Abstract: Sterile barriers or sterile drapes that can be used with medical devices, including hand-held or self-supported X-ray equipment, are described in this application. In particular, this application describes sterile drapes that can be used with a medical device, the drape comprising a closed end portion, a middle portion with a size sufficient to enclose a part of the medical device being used near a patient, and an open end portion, the end portion configured to be closed by a user once the middle portion encloses the part of the medical device being used near a patient, wherein the sterile drape creates a sterile barrier around substantially the entire medical device once the open end is closed. Using the sterile drape allows the medical device, such as a hand-held or self-supported X-ray device, to be used in a medical procedure that requires a sterile field near the patient without disrupting that sterile field. Other embodiments are described.

    Abstract: Three dimensional x-ray imaging systems are described in this application. In particular, this application describes a 3D dental intra-oral imaging (3DIO) system that collects a series of 2D image projections. The x-ray imaging system comprises a housing, an x-ray source attached to a articulating or motion gantry configured to move the source within the housing to multiple positions, an x-ray detector array located on an opposite side of an object to be imaged from the x-ray source, where the detector array is synchronized with the x-ray source to capture 2D images of the object when the x-ray source is located in multiple imaging positions, and a processor configured to accept the 2D images and reconstruct a 3D image. The multiple imaging positions can be located on a plane substantially parallel to the x-ray detector array. Other embodiments are described.

  • Publication number: 20190117304
    Abstract: A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed cooling fluid space around the transmission line. Circulation of cooling fluid is guided in the cooling fluid space by a guide sleeve. A fluid circulation system provides a plurality of fluid supply connectors and fluid return connectors which can be connected and used with any number of applicators between one and the number of the fluid supply connectors provided by the system. A portion of the applicator inserted into the tissue can stick to the tissue to stabilize the applicator during treatment. A warning marking on the applicator can be used during track ablation to prevent ablation of the patient skin tissue.

  • Patent number: 9993294
    Abstract: A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed fluid space around the transmission line. A fluid circulation system circulates fluid in the fluid space. A portion of or all of the circulating fluid can be injected into tissue that surrounds the applicator body from approximately the proximal end of a desired heating zone produced by microwave energy radiated from the antenna along the applicator body toward the proximal end of the applicator to hydrate and wet the tissue outside the proximal end of the desired heating zone to reduce the drying of this tissue and limit extension of the heating and ablation zone proximally along the applicator body.

  • Publication number: 20180108447
    Abstract: Small, portable, and collapsible X-ray devices are described in this application. In particular, this application describes a portable X-ray device that contains a C-shaped support arm, an X-ray source contained near one end of the support arm, and an X-ray detector contained near the other end of the support arm, and the X-ray source is enclosed in a housing that also encloses a power source and a power supply. The X-ray device is portable since it can be configured to be carried by hand from location to location without using wheels or a gantry. The C-shaped support arm capable of rotating around an object to be analyzed that remains in a substantially fixed location when removably attached to a support structure using a connection that also allows the connection point to slide along the arc of the C-shaped support arm. The x-ray device can be quickly de-coupled from the support structure for handheld or table-top use.

  • Patent number: 8414570
    Abstract: A microwave applicator for insertion into living body tissue for use in microwave coagulation and ablation treatments includes a microwave transmission line extending between an attachment end of the applicator and an antenna toward an insertion end of the applicator with an outer conductive sleeve forming an enclosed cooling fluid space around the transmission line. Circulation of cooling fluid is guided in the cooling fluid space by a guide sleeve. A temperature sensor senses the approximate temperature of cooling fluid to indicate cooling fluid is circulating. A multiplexing and power splitting circuit provides outputs tuned for one or for more than one applicator to be attached and detects the number of applicators and correct connection. A cadence sound generator can be used in conjunction with depth markings on the applicator to provide substantially constant withdrawal of the applicator from the treated tissue after treatment to provide track ablation.

  • Patent number: 8306628
    Abstract: A hyperthermia treatment system for heating a selected region within a target body that includes a power source and a plurality of electromagnetic applicators that are in electrical communication with the power source and arranged in a surrounding array around a focal region to concentrate their combined radiation output onto the focal region. The treatment system also includes a support mechanism that is adapted to support a target body within the surrounding array of applicators, and a positioning mechanism adapted to move the support mechanism and align the selected region within the target body with the focal region. Furthermore, the positioning mechanism is adapted to compensate for movement of the focal region in response to an interaction between the combined radiation output and the target body.
