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.

Claims

1. A tubing assembly for use in conjunction with a signal generator having a connector, a magnetic field generator and at least one elongated electrical conductor coupling the connector to the magnetic field generator, the elongated electrical conductor having a diameter, the tubing assembly comprising:

a tubular insulator having a first end connected to the connector, a second end, an internal diameter and an external diameter, the internal diameter being substantially equal to or greater than the diameter of the elongated electrical conductor;

a union device having a first end and a second end, the first and second ends each having an internal diameter and an external diameter, the first end of the union device being coupled to the second end of the tubular insulator, the internal diameter of said first end being substantially equal to or larger than the external diameter of the second end of the tubular insulator, wherein the union device comprises a position controller, a position adjuster, or an elongated neck defining a passage, wherein the tubular insulator is secured to the union device at a user-selectable location within the passage;

a fastener securing the tubular insulator to the user-selectable location within the passage of the union device;

a tubular connector having a plurality of ends, a first one of the ends being attached to the second end of the union device;

a catheter having a first end and a second end, said first end being attached to a second one of the ends of the tubular connector; and

an end member attached to and surrounding the second end of the catheter, wherein the end member includes a first portion defining a passage and an opening.

2. The tubing assembly of claim 1, wherein the union device includes an elongated neck positioned between the first and second ends of the union device.

3. The tubing assembly of claim 1, wherein the union device includes a gripping member positioned between the first and second ends of the union device.

4. The tubing assembly of claim 1, wherein the union device includes a position controller.

5. The tubing assembly of claim 1, wherein the union device includes a stop.

6. The tubing assembly of claim 1, wherein the tubular connector has a medicine branch, a feeding branch, a connection branch and a plurality of movable arms.

7. The tubing assembly of claim 1, wherein the catheter includes an external surface having a plurality of designated unit markings uniformly spaced along the catheter.

8. The tubing assembly of claim 1, wherein the end member includes a second portion having a rounded shape, further wherein the first portion has a collar.
