Abstract
Intravenous access is achieved by introducing a catheter having a guidewire safety tip at its distal end. The safety tip can be advanced and retracted using a slider disposed over an access needle which is initially present in the catheter. After the catheter has been properly positioned, the access needle and guidewire may be removed so that the catheter is available for use.
