Patent number: 9744267Abstract: A rapid method for preparing stem cell and physiologically acceptable matrix compositions for use in tissue and organ repair is described. Compared with previous tissue engineering materials, the stem cell-matrix compositions of the present invention do not require long-term incubation or cultivation in vitro prior to use in in vivo applications. The stem cells can be from numerous sources and may be homogeneous, heterogeneous, autologous, and/or allogeneic in the matrix material. The stem cell-matrix compositions provide point of service utility for the practitioner, wherein the stem cells and matrix can be combined not long before use, thereby alleviating costly and lengthy manufacturing procedures. In addition, the stem cells offer unique structural properties to the matrix composition which improves outcome and healing after use. Use of stem cells obtained from muscle affords contractility to the matrix composition.Type: GrantFiled: December 17, 2015Date of Patent: August 29, 2017Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Michael B.

Publication number: 20160019593Abstract: Systems and methods for presenting ephemeral promotions to consumers are described, in which a time-limited promotion is displayed alongside consumer-directed content on a computing device used by a consumer. The time-limited promotion is ephemeral and disappears if the computing device does not detect customer engagement of the promotion within a time limit for the promotion. An advertising server transmits an advertisement, a promotion, a time limit setting and instructions over a network to the computing. The instructions are configured to cause the computing device to display the advertisement near the consumer-directed content, to display the promotion upon the computing device detecting consumer engagement with the advertisement within the time limit and to terminate display of the advertisement if the computing device does not detect the consumer engagement within the time limit. Further systems and methods are set out.Type: ApplicationFiled: June 24, 2015Publication date: January 21, 2016Inventors: Marvin IGELMAN, Steve CHUNG, Jungsoo PARK

Publication number: 20050080434Abstract: Described herein is a device that may be used in various applications, such as medical applications, and, particularly in laparoscopic procedures, to manipulate and/or introduce objects within or into the body. In one embodiment of the invention, a device includes a cannula with a handle that remains exterior to the body and an extendable member on a portion of the device that may be inserted into the body. The handle, which controls the extendable member, may be moved in an axial direction to extend or retract the extendable member from the interior of the cannula. It may also be rotated to swivel the extendable member. Furthermore, the extendable member may include at least one hole that may be used to, for example, grasp a surgical suture or suture needle. Thus, the device may be used to introduce such objects into the body and manipulate them therein.Type: ApplicationFiled: May 10, 2004Publication date: April 14, 2005Applicant: Cedars-Sinai Medical CenterInventors: Steve Chung, Gerhard Fuchs

Patent number: 6025657Abstract: A power operator for switchgear and the like is provided that is capable of either power or manual operation without the necessity of any decoupling or mode selection. The power operator is compact and easily affixed over a manual operating shaft of switchgear. The manual drive capabilities are always coupled for operation without any backdriving of the power source. The power operator includes a drive output affixed to the switchgear operating shaft, a manual operating shaft, and an arrangement for selectively coupling a power-driven input to the switchgear operating shaft. In a specific arrangement, the control arrangement of the power operator senses the position of the drive output and also senses the current drawn by the drive source. When controlling switchgear having a stored energy mechanism, operating positions are detected by sensing the tripping of the stored energy mechanism via the sensed current through the drive source.Type: GrantFiled: June 12, 1998Date of Patent: February 15, 2000Assignees: S&C Electric Company, S&C Electric Canada Ltd.Inventors: Steve Chung-Bun Lo, Todd W.
