1. A delivery system for the percutaneous insertion of a self-expanding vena cava filter being formed with a length along a longitudinal filter axis, said system comprising:

  • an elongated, radially flexible and axially stiff tubular member extending proximally from a distal end and having a distal end section;

    a segment carried in said distal end section for constraining the filter in a compact condition substantially coaxially with said tubular member, said segment being relatively short compared to the axial length of the filter and having an inner surface that resists penetration by the filter thereby to protect said tubular member from damage during transport of the filter; and

    a displacement member attached to said tubular member for displacing the filter from said segment thereby to deploy the filter.
