  • Patent number: 9352147
    Abstract: A lead anchor includes a body defining a lead lumen having a first opening and a second opening through which a lead can pass. The body further defines a transverse lumen that intersects the lead lumen. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener anchors the lead to the body through the transverse lumen by deforming a portion of the lead. The transverse lumen is configured and arranged to receive the fastener. At least at least two suture tabs extend from the exterior member and are configured and arranged for receiving a suture to suture the lead anchor to patient tissue.

  • Patent number: 9322062
    Abstract: A biochip for molecular detection and sensing is disclosed. The biochip includes a substrate. The biochip includes a plurality of discrete sites formed on the substrate having a density of greater than five hundred wells per square millimeter. Each discrete site includes sidewalls disposed on the substrate to form a well. Each discrete site includes an electrode disposed at the bottom of the well. In some embodiments, the wells are formed such that cross-talk between the wells is reduced. In some embodiments, the electrodes disposed at the bottom of the wells are organized into groups of electrodes, wherein each group of electrodes shares a common counter electrode. In some embodiments, the electrode disposed at the bottom of the well has a dedicated counter electrode. In some embodiments, surfaces of the sidewalls are silanized such that the surfaces facilitate the forming of a membrane in or adjacent to the well.

  • Patent number: 9296358
    Abstract: A motor vehicle airbag system comprises a dual chambered combined head, torso, and knee airbag having a head and torso chamber and a lower extremities chamber in fluid communication with the head and torso chamber. A multidirectional inflator substantially simultaneously inflates both of the head and torso chamber and the lower extremities chamber. The head and torso chamber in the inflated condition acts against a head and a torso of the motor vehicle occupant to generate a restraining force against the occupant to mitigate contact of the occupant head and torso with the upper portion of the instrument panel during the impact event. The lower extremities chamber in the inflated condition acts against the pair of knees of the occupant to mitigate contact of the knees of the occupant with the lower portion of the panel during the impact event.

  • Patent number: 9093818
    Abstract: Monolithically integrated optical resonators are disclosed. An optical resonator may be a nanopillar optical resonator that is formed directly on a substrate and promotes a helically-propagating cavity mode. The helically-propagating cavity mode may result in significant reflection or, total internal reflection at an interface of the nanopillar optical resonator and the substrate even if refractive indices of the nanopillar optical resonator and the substrate are the same or similar. As a result, strong optical feedback, and thus strong resonance, may be provided in the nanopillar optical resonator.
