  • Patent number: 10772623
    Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

  • Patent number: 7659981
    Abstract: A system for probing a DUT is disclosed, the system having a pulsed laser source, a CW laser source, beam optics designed to point a reference beam and a probing beam at the same location on the DUT, optical detectors for detecting the reflected reference and probing beams, and a collection electronics. The beam optics is a common-path polarization differential probing (PDP) optics. The common-path PDP optics divides the incident laser beam into two beams of orthogonal polarization—one beam simulating a reference beam while the other simulating a probing beam. Both reference and probing beams are pointed to the same location on the DUT. Due to the intrinsic asymmetry of a CMOS transistor, the interaction of the reference and probing beams with the DUT result in different phase modulation in each beam. This difference can be investigated to study the response of the DUT to the stimulus signal.

  • Patent number: 7616312
    Abstract: An apparatus and method for laser probing of a DUT at very high temporal resolution is disclosed. The system includes a CW laser source, a beam optics designed to point two orthogonally polarized beams at the same location on the DUT, optical detectors for detecting the reflected beams, collection electronics, and an oscilloscope. The beam optics defines a common-path polarization differential probing (PDP) optics. The common-path PDP optics divides the laser beam into two beams of orthogonal polarization. Due to the intrinsic asymmetry of a CMOS transistor, the interaction of the beams with the DUT result in different phase modulation in each beam. This difference can be investigated to study the response of the DUT to the stimulus signal.
