Abstract:
A sealing conduit, comprising:a. a cylindrical member, said cylindrical member having a distal end and a proximal end with a continuous, longitudinally aligned central lumen formed therein;b. an annular lip structure formed on said distal end of said cylindrical member, said annular lip structure capable of being disposed between a retracted position inside said cylindrical member and an extended position on said distal end of said cylindrical member, said annular lip structure capable of preventing the outward migration of said cylindrical member in a portal when inserted said cylindrical member is inserted therein and said annular lip structure is extended from said cylindrical member;c. a removable penetrating member longitudinally disposed inside said cylindrical member, said penetrating member capable of supporting said cylindrical member when said cylindrical member is inserted into a portal;d. an upper sealing member capable of moving downward longitudinally along said cylindrical member and pressed against the outside surface of the tissue surrounding a portal formed therein, said upper sealing member capable of sealing said portal and preventing the inward migration of said cylindrical member through the portal; and,e. a moving means capable of selectively moving said annular lip structure from a retracted position to an extended position from said cylindrical member, said moving means also capable of moving said upper sealing member along said cylindrical member to force said upper sealing member and said annular lip structure together to securely hold and form a seal around said portal.
