  • Patent number: 11407365
    Abstract: A device, system and method for protecting a tailgate of a pickup truck while also protecting a bed of the pickup truck includes a flexible mat having perforations to allow water and debris to pass therethrough and configured to slide along the bed of the pickup truck toward the tailgate such that a portion of the flexible mat extends upward and over a top edge of the tailgate, allowing bicycles to be carried upon the pickup truck while the bicycles extend over the top edge of the tailgate.

  • Patent number: 10306948
    Abstract: A method of manufacturing footwear and an article of footwear having a tapered heel in part defining an impact point associated with a padded impact zone which first strikes a surface upon a foot plant and a plate embedded within a sole of the article such that the plate supports the heel of the sole from flexing or collapsing. The impact point is part of an impact area (F) positioned adjacent an ankle pivot axis of the wearer's ankle, and in one aspect is positioned at or slightly posterior the ankle pivot axis. In one aspect the method includes configuring a sole of the footwear based on an ankle pivot characteristic or balance pivot characteristic of a wearer in a custom manufacture or based on the same of a typical or an ordinary wearer in a non-custom manufacture.

  • Patent number: 9629413
    Abstract: An article of footwear having a tapered heel in part defining an impact point associated with a padded impact zone which first strikes a surface upon a foot plant and a plate embedded within a sole of the article such that the plate supports the heel of the sole from flexing or collapsing, the impact point positioned anterior a pivot point of the wearer's ankle. In one aspect the plate avoids positioning at a lateral midfoot area of the sole to allow for impact zone padding and promotes avoiding or reducing heel strike forces when walking or running.

  • Patent number: 9017327
    Abstract: A medical instrument having an elongate frame with proximal and distal ends, an operating assembly at a proximal region of the frame, and a working assembly at a distal region of the frame. The working assembly has a cantilevered tip with a free end and is reconfigurable by an operator through the operating assembly by selectively reorienting the tip relative to: a) the frame; and b) a reference plane extending through the frame orthogonally to the central axis at a location on the frame spaced axially from the working assembly toward the operating assembly. The tip in one position projects in a first axial direction toward the reference plane. The working assembly has at least one cautery component that: a) contacts a human body part at the cutting location; and b) is operable to generate a current that dissects a contacted portion of the human body part.

  • Patent number: 8845671
    Abstract: A method and apparatus for preparing an access site on a patient for insertion of a catheter into one of the patient's veins. The method includes the steps of: providing a tract forming assembly having a leading cutting edge and a dilating body defining a trailing dilating portion, with the cutting edge and dilating body together defining a tract forming unit; advancing the tract forming unit into skin at the access site so that: a) the cutting edge progressively forms a tract through the patient's skin and subcutaneous tissue towards the one vein; and b) the dilating body follows the cutting edge and dilates the tract; and removing the tract forming unit from the dilated tract so that no component resides in the dilated tract to allow a catheter to be directed through the dilated tract and into the one vein.
