Abstract
The present invention provides a protective sheath assembly which combines the function of an introducer, the function of a protective sheath and the function of a sealing valve in an integrated assembly. The protective sheath assembly of the present invention preferably comprises a protective sheath, a strain-relief tubing, and a connecting member or a hub. These parts are mounted, removably or permanently, into an integral device. The protective sheath assembly can also be used in combination with an introducer such as a needle introducer. The protective sheath has a proximal end, a distal end, and an elongated hollow body defining a lumen along the longitudinal direction of the protective sheath. A hub is provided to secure the proximal end of the protective sheath to an introducer. The lumen of the protective sheath serves to accommodate and protect a balloon catheter, as well as seal around the catheter.
