## Abstract

A drainage or infusion catheter and methods of use are disclosed. In one embodiment, the catheter includes a tube body having a proximal end and a distal end, and a plurality of ports arranged along the tube body from the distal end to the proximal end. The distal end of the tube body is configured to deform around itself into a substantially spiral shape so as to cover at least one of the plurality of ports located near the proximal end of the tube body. In another embodiment, a flap is configured to erupt from apertures arranged in the tube and extend outwardly around the tube body so as to cover at least one of the plurality of ports located near the proximal end of the tube body.

## Claims

### Claim 1

A method for inserting a drainage or infusion catheter into a cavity of a subject comprising:
providing a catheter comprising:
a tube body defining a passageway therethrough, the tube body having a proximal end and a distal end, and a central region extending between the proximal end and the distal end;
a plurality of ports arranged along the tube body from the distal end to the central region, the plurality of ports extending into the central region; and
at least two apertures arranged in the central region of the tube body;
inserting the catheter into the cavity; and
inserting an intraluminal catheter within the tube body of the catheter, the intraluminal catheter having a flap;
wherein the flap erupts from the at least two apertures and extends outwardly around the tube body so as to surround at least one of the plurality of ports located in the central region of the tube body.

### Claim 2 (depends on 1)

The method of claim 1 in which the cavity comprises a ventricle and the drainage catheter drains cerebral spinal fluid.

### Claim 3 (depends on 1)

The method of claim 1 in which the cavity comprises an abdominal cavity.

### Claim 4 (depends on 1)

The method of claim 1 in which the cavity comprises a gallbladder.

### Claim 5 (depends on 1)

The method of claim 1 in which the cavity comprises a pleural space.

### Claim 6 (depends on 1)

The method of claim 1 in which the cavity comprises a heart chamber.

### Claim 7 (depends on 1)

The method of claim 1 wherein the catheter comprises a shape memory material.
