Claim Text:
1. An embolus filter delivery device for delivering an embolus filter to a delivery site within a human living host, comprising: a) a pusher assembly having a frame and a pusher member movable with respect to the frame, the pusher assembly having a pusher assembly end portion with a pusher assembly connector, the pusher member movable with respect to the pusher assembly connector; b) an introducer sheath having an inner lumen and that is configured to be inserted into a circulatory system of a human living host, said introducer sheath having first and second opposed sheath ends, said introducer sheath having a cylindrical outer wall extending from the first sheath end to the second sheath end, said cylindrical outer wall entirely circumferentially surrounding the inner lumen; c) first and second removable seals on the introducer sheath in a sheath initial position wherein the first seal is attached at the first sheath end and the second seal is attached at the second sheath end such that the first and second seals and the cylindrical outer wall seal the inner lumen; d) an embolus filter housed in said inner lumen in between said first and second sheath seals and first and second sheath ends in said sheath initial position, wherein in said sheath initial position the first sheath end has a first sheath end connector and the second sheath end has a second sheath end connector, each of the first and second sheath end connectors enabling connection of a said first and second sheath end to the pusher assembly frame at the pusher assembly connector; e) wherein in said sheath initial position either of said first and second sheath end connectors is selectively connectable to the pusher assembly connector; f) wherein a connection of the pusher assembly connector to the introducer sheath at the first sheath end connector enables the pusher member to enter the inner lumen via the first sheath end and to push the filter out of the second sheath end; g) wherein in said sheath initial position each of the first and second sheath ends is sized and shaped to be insertable into the circulatory system of the human living host; and h) wherein when the pusher assembly connector and a selected sheath end connector are connected together, and the introducer sheath is inserted into the living host via jugular or femoral access, the other one of the sheath ends is a free end that defines a discharge opening into the living host's circulatory system at a vena cava and enables discharge and placement of the embolus filter at the vena cava of the living host.
