Abstract

A catheter system for accessing the central venous system through an occlusion in the neck region.

Claims

1. A kit for providing access to a central venous system of a patient comprising:

a radiopaque target having a radiopaque area and a radiolucent area, the radiopaque target being adapted to be applied to an exterior surface of said patient to define an exit point on the patient; and

a catheter comprising;

a shaft having a proximal end and a distal end;

a blunt dissection tip disposed at the distal end of the shaft, the blunt dissection tip having a side aperture and a slot;

a departure angle guide tube configured to extend out the side aperture of the blunt dissection tip to set a departure angle, in a departure angle plane;

a handle coupled to the proximal end of said shaft, wherein said handle rotates said blunt dissection tip and said slot and indicates and defines a rotational position of the departure angle plane;

a needle wire having a sharp dissection tip, said needle wire configured to extend through the departure angle guide tube, said needle wire having a sharp dissection tip permitting it to track in a substantially straight line from said departure angle guide tube.

2. The kit of claim 1 further comprising:

a delivery sheath sized to introduce said catheter.

3. The kit of claim 1 further comprising:

a dilation catheter sized to accept said needle wire.
