  • Patent number: 11960636
    Abstract: Examples of wearable systems and methods can use multiple inputs (e.g., gesture, head pose, eye gaze, voice, and/or environmental factors (e.g., location)) to determine a command that should be executed and objects in the three-dimensional (3D) environment that should be operated on. The multiple inputs can also be used by the wearable system to permit a user to interact with text, such as, e.g., composing, selecting, or editing text.

  • Patent number: 8656928
    Abstract: Medical devices are made visible under ultrasonic or magnetic imaging techniques by adding a series of features on their surfaces. The features are desirably placed at more than one angle to the surface in order to enhance the visibility of the surface. Laser-machining can make a series of depressions or voids that are symmetric with respect to the surface and another series of depressions or voids that are non-symmetric. The pattern of voids is also varied by using more than one size of void, the depth of the voids, and the distribution of voids, i.e. more voids in some areas than others.

  • Patent number: 8360995
    Abstract: The present invention provides a wire guide (20) suitable for use in a body vessel, such as a peripheral vessel. The wire guide comprises a core member (22) and a first coiled member (40), each having proximal and distal ends. In one embodiment, the core member comprises at least one recessed portion (36), wherein the proximal end of the first coiled member is seated at least partially within the recessed portion to form a substantially flush exterior surface with the core member. The wire guide further preferably comprises a second coiled member (50) having proximal and distal ends, wherein the second coiled member is disposed distal to the first coiled member. The distal end of the first coiled member may be partially intertwined with the proximal end of. the second coiled member. A shaping ribbon (60) may be disposed substantially beneath the second coiled member to achieve a desired curvature at the distal tip of the wire guide.
