  • Verress needle with enhanced acoustical means
    Patent number: 5256148
    Abstract: A Verres-type needle which has a sharpened outer needle and allows passage of a blunt inner needle within the outer needle. The Verress needle also contains a position indicator to indicate the position of the inner needle within the outer needle, so that the user knows whether the inner needle is in a protective or non-protective position. Further, a liquid level indicator demonstrates the path of liquid flow within the Verress-type needle. Finally, there is an acoustical enhancment mechanism, which allows the user to know whether the blunt inner needle has sprung forward within the abdominal cavity, to its most forward, protective position.
