  • Patent number: 9974535
    Abstract: A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. In so doing, the sections of skin are pushed toward one another thus assuring horizontal and vertical alignment of the two sections of skin. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation.

  • Patent number: 9861379
    Abstract: An approximator device is provided. The approximator device may include an elongate member having a working end and a control end, at least two prongs disposed on the working end configured to engage tissue and longitudinally interface with one another, and a control mechanism disposed at the control end operatively coupled to one or more of the prongs and configured to longitudinally move the one or more prongs between an open position and an approximating position.

This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation. The resulting suturing process is thus much faster than conventional or manual suturing and results in superior wound approximation/alignment that will lead to decreased scarring compared to prior art devices.

  • Publication number: 20090093824
    Abstract: A tissue fastening device for approximating tissue edges with successive placement of fasteners therebetween comprising a proximal portion having a handle and a trigger; a distal portion having an effector end responsive to depression of the trigger; an actuator assembly operably coupled with the trigger; approximation arms disposed in the effector end. The approximation arms are rotatably coupled to the actuator assembly; and a gear mechanism enenmeshingly engageable with the trigger. The gear mechanism is configured to rotate an arcuate needle disposed in the effector end. Method to fasten opposing tissue comprises (a) approximating two opposing tissue edges, the tissue edges comprising a dermal layer; (b) driving an H-fastener vertically through the dermal layer of each of the tissue edges using a tissue fastening device, and (c) advancing the device to an adjacent position between the tissue edges and repeating steps (a) and (b).

  • Patent number: 7422368
    Abstract: A CT scanner includes a base, two fixed portions extending transversely from the base, and a rocking beam pivotally attached to the base about an axis. The CT scanner includes four wheels that allow the CT scanner to move over a floor. A wheel is attached to each fixed portion, and a wheel is attached to each end of the rocking beam. If the CT scanner is positioned on a floor with an unlevel portion, the rocking beam rotates about the axis. One wheel attached to the rocking beam raises in a generally vertical direction, and the other beam attached to the rocking beam lowers in a generally vertical direction so all four wheels contact the floor, stabilizing the CT scanner and preventing rocking.

  • Publication number: 20050027910
    Abstract: In one embodiment, a system for providing both wireline and wireless connections to a wireline interface includes a first wireline interface, a second wireline interface, a wireless interface, and a switch coupled to the first wireline interface, the second wireline interface, and the wireless interface. The switch can selectively couple the first wireline interface to the second wireline interface to allow communication between the first and second wireline interfaces. The switch can further selectively couple the first wireline interface to the wireless interface to allow communication between the first wireline interface and the wireless interface.

  • Publication number: 20030080136
    Abstract: Disclosed is a foil dispensing machine for use in the process of hair coloring and highlighting. The machine can accommodate a commercially available roll of metal foil and includes a motor that can be used to unwind a piece of foil from the roll and dispense the piece from the machine. The machine further includes a cutter that is used to cut the dispensed foil from the remaining foil on the roll. The components of the machine are designed and positioned to reduce the likelihood that the foil will bunch up as it is being unwound from the roll. In some embodiments, the machine also includes a control device that can be programmed or adjusted to cause the machine to dispense foil in pre-set lengths. In some embodiments, the machine may be incorporated with a piece of furniture intended for placement in a hair salon.
