Abstract: A delivery device (suture passer or suture snare) that may be used in both open and endoscopic surgical procedures. The delivery device is designed with an internal member terminating in a snare and a retractable outer sheath (sleeve). The device is passed through tissue, and the outer sheath is retracted (moved back), allowing the snare to open. The suture is captured by the snare, and the outer sheath is then released so that it returns to its distal position, closing the snare and securing the captured suture. Since the snare is exposed by retracting the outer sheath (sleeve), rather than advancing the snare, the space requirement for the device is reduced, as is the possibility that the snare will undesirably contact sensitive tissue.

Abstract: Thus, in one embodiment an apparatus includes at least one processor, at least one display controlled by the processor, and at least one wireless transceiver communicating with the processor. The processor is configured to transmit a message accessible to at least one recipient that includes data representing at least one non-alphanumeric who icon representing a person, at least one non-alphanumeric what icon representing an event and/or activity, and at least one non-alphanumeric when icon representing a time associated with the event and/or activity. Furthermore, at least one of the following represented by data included in the message is modifiable based on input from at least one recipient: the at least one who icon, the at least one what icon, and the at least one when icon.

Abstract: The invention provides a method and system for selectively canceling a specified frequency band in the payload of an optical communication system. This selected frequency band is to be used for launching pilot tones for power measurement and identification. The method controls the intensity of the optical payload signal through an intensity modulator that is included in the optical communication system. The frequency band in payload to be cancelled is removed where as the other frequency components of the payload are passed without attenuation. An embodiment that uses a feed-forward unit, a feedback unit and a control unit for generating a cancellation signal for the intensity modulator is described. An advantage of the method is that it removes a continuum of payload tones in the specified frequency band to be cancelled.

The method for cancellation of cross-talk among multiple channels occurring in a traditional optical amplifier comprises: detecting tones at an input and an output of a Smart Optical Amplifier that includes a traditional optical amplifier and a Cross-talk Cancellation Unit; comparing the detected tones at the input and output of the Smart Optical Amplifier; generating destructive tones with such amplitudes and phases so as to cancel cross-talk; and eradicating cross-talk at the output of the Smart Optical Amplifier by applying the destructive tones in the Cross-talk Cancellation Unit. Eight different embodiments that correspond to different combinations of traditional optical amplifier types and the type of technology (analog or digital) used in processing and control of signals are described.

The device is a two dimensional grating or periodic structure which is symmetric in the X and Y axes. It is comprised of a membrane with holes cut in it that moves downward with the application of a voltage which starts diffracting light. The hole region may have a raised island to provide achromatic behavior.
