    Abstract: A method of performing an operation, e.g. a spinal operation, on a patient using a retractor comprising a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis, and further comprising a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In the method, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision.

  • Patent number: 10004610
    Abstract: Systems and methods for facilitating treatment are disclosed that can include the use of imaging techniques in conjunction with one or more non-invasive techniques for modifying tissue, e.g., tissue in or around the spine. Depending on the type of treatment to be performed, various imaging modalities may be suitable for visualizing the tissue. Energy can be applied to tissue from outside of the body such that the tissue is modified in a non-invasive manner. For example, focused ultrasound can be used to dissect body tissues or can be applied to specific regions of tissue to change a characteristic of the tissue, e.g., increase its elasticity. The methods disclosed herein can be stand-alone treatments or can be performed prior to one or more surgical procedures. For example, non-invasive imaging and modification of body tissues can facilitate accessing the spine, preparing an interbody space, and/or surgically correcting the spine.

  • Patent number: 9433457
    Abstract: A surgical instrument for thermally-mediated therapies in targeted tissue volumes and for causing thermal effects in polymer tissue-contacting members. In one embodiment, the instrument has a working end with an interior chamber that is supplied with a biocompatible liquid. An energy source causes a liquid-to-vapor phase change within the interior of the instrument. The vapor phase media then is ejected from the working surface of the instrument, and a controlled vapor-to-liquid phase change in an interface with tissue applies thermal energy substantially equal to the heat of vaporization to ablate tissue. The vapor-to-liquid phase transitions, or internal energy releases, can be provided about thin-film flexible structures for engaging body lumens and cavities. An exemplary embodiment can be used for shrinking, sealing, welding or creating lesions in tissue—while causing limited collateral thermal damage and while totally eliminating electrical current flow in the engaged tissue.

    Abstract: A device for preparing a thermoplastic material, with dry heat, for use in patient fixation. The device generates circulated heat to a threshold temperature. Once the thermoplastic material has become pliable, it is molded into a cast for fixation purposes. The circulated heat may be generated by a device having a housing and a support member movably attached to the housing. The device also includes a heating element and an array of circulation elements to push air centrally at the central region and drawing air from a periphery region concurrently.

  • Patent number: 8926597
    Abstract: An instrument guide device comprises an elongated guide shaft having proximal and distal ends and including an instrument lumen for receiving therethrough a manually operated instrument having an instrument shaft. A distal bendable member is disposed at the distal end of the guide shaft and a proximal bendable member is disposed at the proximal end of the guide shaft. Actuation means extends between the distal and proximal bendable members and provides a bending of the distal bendable member controlled from the proximal bendable member. The proximal bendable member is controlled from the manually operated instrument to cause a corresponding bending of said distal bendable member.

  • Patent number: 8920372
    Abstract: An IV line temperature controlled warming device includes a housing and a fluid cassette or cartridge that receives fluid from an IV line and includes intravenous line tubing arranged in a preformed configuration. The configuration includes tubing sections arranged in generally circular and concentric portions and a central serpentine tubing section that basically reverses fluid flow and facilitates flow in opposing directions within adjacent tubing sections. The fluid cassette is retained within the device on a base plate partially disposed within a device housing interior, while a housing cover is selectively opened and closed to permit access to the base plate. The base plate includes a heater plate disposed thereon, while the cover and heater plate each include heating elements to apply heat to opposing surfaces of the tubing cassette. The heating elements are controlled by a controller in response to measured temperatures of the heater plate and fluid.

  • Publication number: 20140303557
    Abstract: An apparatus heats fluids. A number of lithium-ion cells are positioned within a housing. A first connector is positioned on a first end of the housing and opperably connected to the number of lithium-ion cells. The first connector is configured to receive electrical power from a power source. A second connector is positioned on a second end of the housing and opperably connected to the number of lithium-ion cells. A heating element has a tube for transferring fluid. The heating element is configured to connect to the second connector. A controller is positioned within the housing and opperably connected to the number of lithium-ion cells and the second connector. The controller is configured to monitor a rate at which the electrical power is received by the heating element and limit an amount of the electrical power received by the heating element when the rate reaches a predetermined level.

  • Publication number: 20140276545
    Abstract: The present invention relates in one aspect to an infusion fluid warmer which comprises a casing shell having an upper wall structure and a lower, opposing, wall structure. The casing shell encloses a fluid channel or passage extending through the casing shell in-between the upper and lower wall structures and fluid inlet and outlet ports coupled to opposite ends of the fluid channel or passage to allow a flow of infusion fluid through the casing shell. A housing shell is formed in a thermally conducting and electrically insulating material and a heating element is bonded to the housing shell and thermally coupled thereto. The fluid channel or passage extends through the housing shell or extends around the housing shell such that heat energy is transferred to the infusion fluid by direct physical contact with housing shell material.

  • Patent number: 8821440
    Abstract: An injection device has a dispensing chamber housing, a plunger, and a temperature control device. The dispensing chamber housing has a first part and a second part. The first part is thermally coupled to a needle. The second part is thermally coupled to the first part. The second part has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with an inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The temperature control device at least partially surrounds the dispensing chamber housing and is capable of altering a temperature of the substance in the dispensing chamber. The second part has a greater thermal coefficient than the first part.
