Abstract: Methods and apparatus are described that use an array of light sources that project converging light beams to control treatment distance. This approach controls treatment distance without contacting the patient or increasing the risk of pathogenic contamination. The approach can be used to control an optimal distance, and is compatible with various medical treatment devices including cold plasma treatment devices.

Abstract: A method is provided for manipulating a spinal body spacer for use in spinal surgery on a patient. The method includes attaching a placement tool to the spinal body spacer and manipulating the placement tool so as to locate the spinal body spacer in a desired location. The placement tool can by removed by unscrewing the placement tool from a threaded receiving aperture of the spinal body spacer. The method also includes passing a tip of an extraction tool through the threaded receiving aperture of the spinal body spacer, the tip of the extraction tool having at least one tab. The tip of the extraction tool is rotated such that the at least one tab of the tip of the extraction tool passes through keyways of the spacer and extends into the interior space of the spinal body spacer.

The spacer may have an outer face positioned around the opening and the placement tool may have a contact face that comes into contact with the outer face when the placement tool is fully connected with the spacer. The extraction tool has a tip configured to pass through the opening of the spacer.

Abstract: An inhalable cold plasma mask device for generation of a breathable cold plasma for delivery to a patient. A biocompatible gas is received in a dielectric barrier discharge (DBD) device that is energized by an electrode that receives energy from a pulsed source. The DBD device can be grounded by a grounding structure. A grounding screen can be used prior to inhalation of the cold plasma. The inhalable cold plasma mask device includes the use of a single-layer or a two-layer approach to its construction. The inhalable cold plasma mask device can have one or two DBD devices. Such a device and associated method can be used to treat upper respiratory tract infections, as well as reducing inflammation, sinus and esophageal polyps in both size and frequency of occurrence.

Abstract: A compact cold plasma device for generating cold plasma having temperatures in the range 65 to 120 degrees Fahrenheit. The compact cold plasma device has a magnet-free configuration and an induction-grid-free configuration. An additional configuration uses an induction grid in place of the input electrode to generate the cold plasma. A high voltage power supply is provided that includes a controllable switch to release energy from a capacitor bank to a dual resonance RF transformer. A controller adjusts the energy input to the capacitor bank, as well as the trigger to the controllable switch.

Abstract: A cold plasma mask application device for delivery of a cold plasma to the face of a patient. An appropriate gas is introduced into a gas containment area that is energized by one or more electrodes that receive energy from a pulsed source. The plasma can be prevented from contact with the patient's face, or can be allowed to make contact with the patient's face at the appropriate treatment area. A three-layer approach to the manufacture of the cold plasma mask application device is also described. Such a device and method can be used to treat acne as well as complex facial wounds such as those resulting from trauma, melanoma, and other cancers of the face, rosacea, and psoriasis.

Abstract: A cold plasma treatment device for delivery of a cold plasma to patient treatment area. Gas is fed to a gas compartment where it is energized by an electrode coupled to a pulse source to thereby generate a cold plasma. A dielectric barrier is sandwiched between the gas compartment and the electrode to form a dielectric barrier discharge device. The cold plasma exits the gas compartment via a bottom member having a plurality of holes. Gases that can be used include noble gases such as helium or combinations of noble gases.

Abstract: A cold plasma sterilization device for sterilization of objects such as medical instruments. Gas is fed to a plasma chamber where it is energized by one or more electrodes coupled to a pulse source to thereby generate a cold plasma inside the plasma chamber. A dielectric barrier is sandwiched between the gas compartment and the electrodes to form a dielectric barrier discharge device. Inside the plasma chamber, one or more conductive stands that are coupled to ground hold the object to-be-sterilized. The cold plasma exits the plasma chamber, where it is recirculated for further use as a plasma source in subsequent cycles. Gases that can be used include noble gases such as helium, or combinations of noble gases.

Abstract: A method for monitoring pressure at one or more points on an individual and automatically adjusting one or more sections of a support structure. The method includes periodically receiving pressure data from one or more radio frequency addressable sensors placed on an individual; determining, based on the received pressure data, whether an adjustment in the support structure is required; systematically adjusting cells located within the plurality of zones, one zone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a zone, systematically adjusting cells within the plurality of subzones for that zone, one subzone at a time, until an improvement in pressure data is indicated. If an improvement in pressure data is indicated for a subzone, systematically adjusting cells in that subzone, one cell at a time, until an improvement in pressure data is indicated.

Abstract: Provided is a modular pedicle screw assembly which includes various components that may be configured in various manners so as to provide different functionalities to the pedicle screw assembly. This advantageously decreases surgery time, reduces repetitive and tedious surgical steps, and allows for streamlining inventory of expensive medical equipment. In one embodiment, a pedicle screw assembly includes a pedicle screw, a rod holding element, an insert, a rod, and a set screw. The insert may have a uniplanar configuration which allows movement of the insert, prior to final attachment, in a plane of motion. The insert may optionally have a monoaxial configuration which prevents movement of the insert. A method is also provided for securing a rod to a pedicle screw assembly. Also provided is an assembly tool for use in assembling a pedicle screw assembly.

Abstract: An assembly for the fixation of a spinal facet joint, including an outer shank, an inner shank and a tip, such that rotation of the inner shank with respect to the outer shank causes the tip to move into the outer shank. Movement of the tip causes deformation of the distal end of the outer shank such that the distal end of the outer shank is larger in diameter than the hole through which it was inserted, said deformation causing increased compression and reduced chance of device loosening.
