Abstract
A tubing assembly having a signal generator placement control device for use in conjunction with electronic catheter guidance systems. The control device facilitates control of the position the guidance systems'"'"' signal generator relative to the end of the tubing assembly. The tubing assembly includes a tubular insulator coupled to one end of the control device, and the tubing assembly includes a tubular connector attached to the other end of control device. Also, the tubing assembly includes a catheter attached to the tubular connector and an end member attached to the catheter.
