  • Publication number: 20220183699
    Abstract: A device that holds a radial sheath, catheter or similar structure in place during surgical procedures. The device has a strap configured to fit around a patient's wrist and a two-part section that includes a sheath holder or clamp. The clamp is configured to accept a free end of the sheath or other device and to allow the physician access to the open end of that sheath so that they can insert instruments through it. The second section contains a compression device that, when positioned over the puncture site, can be expanded such that it provides pressure and patent hemostasis to the site to stop bleeding. Adhesive surfaces with peel away releasable liners on one or more surfaces of the device allow the flap featuring the compression balloon to be folded over onto the flap containing the sheath clamp and hold it in place.

  • Patent number: 10563457
    Abstract: A hand-powered photovoltaic module hoist having a sled that slides along a ladder, and a pulley assembly mounted at the top of the ladder with a first cord to lift the sled and a second safety release cord to permit the sled to descend down the ladder. The sled is not attached to the ladder and the pulley assembly is a removable frame that is hung onto rungs of the ladder such that the hoist can quickly be installed on a standard ladder.
