  • Patent number: 10864354
    Abstract: Apparatuses, systems, and methods for crossing a tissue region may include a catheter and a tip section arranged therewith. The tip section may be configured to puncture the tissue region and create an opening therein, dilate the opening in the tissue region, and pass through the opening.

  • Publication number: 20190255285
    Abstract: Tissue puncture devices, and systems and methods for accessing tissue (e.g., cardiovascular tissue) according to the present disclosure may include a tubular sheath extending along a longitudinal axis, the tubular sheath having a proximal end and a distal end, a needle disposed coaxially in the sheath, the needle having a proximal end and a distal end and being movable along the longitudinal axis of sheath, and a needle control mechanism disposed at the proximal end of the needle, the needle control mechanism being configured to lock the distal end of the needle in a first position retracted within the distal end of the sheath, and release the needle to an unlocked second position such that the distal end of the needle is extendable beyond the distal end of the sheath.

  • Patent number: 7343693
    Abstract: A flexible optical marker is applied to an optical scale substrate to make an optical scale assembly for an optical position encoder. The marker may be a limit marker, index marker, or other type of marker. The marker substrate may be a plastic film such as polyester, singulated from a “recombine” roll created by a web process. The marker has a microstructured pattern on one surface that is covered with a reflective metal coating. The marker also has an adhesive layer and is affixed to the optical scale substrate by a process of aligning the marker to an edge of the scale and then applying pressure to the upper surface of the marker. The marker may be applied with a handle portion that is separated from the marker after the marker is affixed. The marker may be especially useful with a flexible scale substrate such as a metal tape substrate.

  • Patent number: 7298533
    Abstract: An optical layer comprises a sheet of material having a surface. The surface comprises a plurality of optical elements. The optical elements are comprised of microscopic patterns in the surface that cooperate to produce an image. Each of the elements has a focal length. At least some of the focal lengths are significantly different from other focal lengths, such that some portions of the surface appear to be closer to a viewer than other portions of the surface.
