Abstract

An apparatus for sealing a passage through tissue communicating with a body lumen is provided. The apparatus includes an elongate member having a proximal end a distal end and a lumen extending from the distal end toward the proximal end defining a longitudinal axis. A plug member is disposed on the distal end and extends distally from the elongate member in a pre-deployed and deployed configuration. The plug member includes a distal port therein in communication with the lumen and has a cross-sectional diameter at a plug proximal end and a plug distal end greater than a cross-sectional diameter of the distal end of the elongate member in the pre-deployed configuration. The apparatus also includes a member extendable distally from the distal port, the member including a proximal end and a distal end.
