Patent number: 9974535Abstract: 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.Type: GrantFiled: February 24, 2015Date of Patent: May 22, 2018Assignee: Surgimatix, Inc.Inventors: Jafar Syed Hasan, Wai Ngai Chin, Gary Michael Kobylewski

Patent number: 9861379Abstract: 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.Type: GrantFiled: June 15, 2015Date of Patent: January 9, 2018Assignee: Surgimatix, Inc.Inventors: Wai Ngai Chin, Gary M.

Patent number: 9844367Abstract: 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. 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.Type: GrantFiled: December 21, 2011Date of Patent: December 19, 2017Assignee: Surgimatix, Inc.Inventors: Gary Michael Kobylewski, Wai Ngai Chin, Jafar Syed Hasan

Publication number: 20090093824Abstract: 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).Type: ApplicationFiled: October 2, 2008Publication date: April 9, 2009Inventors: Jafar S. Hasan, Wai Ngai Chin

Patent number: 7422368Abstract: 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.Type: GrantFiled: October 12, 2006Date of Patent: September 9, 2008Assignee: Xoran Technologies, Inc.Inventors: Joseph Webster Stayman, David C. Brown, Wai Ngai Chin, James F. O'Connell, James A. Bertolina, Dejen Teofilovic

Publication number: 20030080136Abstract: 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.Type: ApplicationFiled: October 25, 2002Publication date: May 1, 2003Applicant: Avec Enterprises, Inc.Inventors: Graciela Santiler Nowik, Wai Ngai Chin, Gary Kobylewski, Yei Feng Moy, Joseph S.
