Abstract
Abstract The catheter protective shield is used to protect a flow directed catheter of the type used in the measurement of central venous pressure and pulmonary wedge pressure. The cathetershield assembly includes front and rear hubs sized to permit movement of the catheter therethrough and an external support tube for interconnecting the front and rear hubs. A flexible protective sleeve interconnects the two hubs. The protective sleeve is substantially longer than the external support tube and is collapsible to permit interconnection of the hubs by the external support tube and may be extended to shield a substantial length of catheter.
