  "abstract": "A multipurpose, flexible cover for medical instruments with a closed-end cover that is optically clear throughout. The transparent cover is used with optical medical instruments such as cameras and lasers. The cover has a closed end that is a homogeneous polyurethane piece folded over itself and sealed along its side edges to form a receptacle to retain the medical instrument. The closed-end portion, which can be associated with a different types of cameras and lasers, is optically clear with surgical clarity.",
  "claims": [
    "1. A transparent, closed-end cover for medical instruments with optical functions comprising a proximal end and a homogenous closed-end portion that is optically clear with surgical clarity wherein the closed-end portion is folded at a distal peripheral edge so that there is no optical distortion along the peripheral edge and wherein the peripheral edge is formed by a continuous piece of material.",
    "2. The cover of claim 1 having side edges formed from the folded closed-end portion wherein side edges are sealed by applied heat.",
    "3. The cover of claim 1 having side edges formed from the folded closed-end portion wherein the side edges have identifiable seams so that the potential distortion of looking through the seam is known to a surgeon.",
    "4. A transparent, closed-end cover for medical instruments with optical functions comprising: a proximal end and a homogenous closed-end portion that is optically clear with surgical clarity further including a drape fastened to the closed-end portion."
