Abstract
A protective sheath for a cannula which has distal end for percutaneous insertion and a proximate end having a hub or like assembly. The protective sheath comprises an elongated, flexible tubular member which slidably fits over the cannula. The tubular member has a distal end which is disposed over the distal end of the cannula and is compressibly retractable therefrom. The distal end of the tubular member has an opening through which the cannula may pass so as to expose the distal end of the cannula during insertion thereof, but when the cannula is withdrawn, the distal end of the sheath extends over and covers the distal end of the cannula.
