Patent ID: 7976518

Claim:
A tubing assembly for use in conjunction with an invasive signal generator, the tubing assembly comprising: a connector configured to connect to the invasive signal generator; a magnetic field generator; at least one elongated electrical conductor connecting the connector to the magnetic field generator, the at least one elongated electrical conductor having a diameter; a tubular insulator having a first end, a second end, an internal diameter and an external diameter, said first end attachable to the connector, the internal diameter of the tubular insulator being substantially equal to or greater than the diameter of the at least one elongated electrical conductor, the at least one elongated electrical conductor extending through the internal diameter of the tubular insulator; a union device having a first end, a second end, an elongated neck, a gripping member, an insert and an internal surface, the first end of the union device being coupled to the second end of the tubular insulator, the internal surface having a stop, the elongated neck, gripping member and insert being positioned between the first and second ends, the first and second ends each having an internal diameter and an external diameter, the internal diameter of said first end of the union device being substantially equal to or larger than the external diameter of the second end of the tubular insulator; a y-port connector defining a medicine branch, a feeding branch, a connection branch and a plurality of movable arms, the feeding branch sized to receive the insert of the union device, each of the movable arms having a stopper; a feeding tube including a body having a first end, a second end and an external surface, said first end being attached to the connection branch of the y-port connector, the external surface having a plurality of designated unit markings uniformly spaced along the body of the feeding tube; and a tip attached to the second end of the feeding tube, the tip including a body having a collar and an end member, the body defining a passage and an opening, the opening positioned between the collar and the end member, a portion of the end member having a rounded shape.
