Abstract
Tear-away sheath introducers for catheters and methods for making and using such introducers are described. The sheath introducers contain movable valves that are encapsulated in a movable housing that allows the valve to move along the introducer axis. As the movable valve and housing travel along the axis, a portion of the hub protrudes past the valve and is exposed. As well, the sheath introducers can also contain a stationary valve and housing that can be opened to expose a portion of the hub when a conduit penetrates the stationary valve. The conduit can include a one-way, two-way, or other suitable valve actuator that can penetrate and open the valve, yet remain attached to a portion of the introducer when the introducer is split for removal from a patient. In both instances, the protruding portion of the hub contains a friction-free pathway for a catheter into the sheath introducer.
