  • Anatomical cavity access sealing conduit
    Patent number: 6228063
    Abstract: A sealing conduit for use with a portal formed on the body which enable surgical, diagnostic and assistive instruments to be inserted into the body during least invasive medical procedures. The sealing conduit includes an elongated cylindrical member with a continuous central lumen therebetween. A flexible annular lip structure is attached or formed on the inside surface of the cylindrical member which is folded in a retracted position inside the cylindrical member or extended through the distal opening thereof. During use, a penetrating member is disposed inside the cylindrical member which is moved downward to forcibly move the annular lip structure from the retracted to the extended position. When the annular lip structure is in the extended position, distal end of the sealing conduit is located just inside the desired vessel or conduit and outward migration of the sealing conduit through the portal is prevented.
