Abstract:
An improved insertion instrument for a vena cava filter is provided and iudes a filter retainer attached to the catheter for preventing accidental ejection of the filter and for enabling retraction of the filter into the carrier body at any time prior to complete ejection; a directional control mechanism attached to the plunger housing for allowing a user to guide the filter retainer through a vascular network; and a simplified plunger locking mechanism on the plunger for preventing premature ejection of the filter.
