Abstract

A drainage catheter according to aspects of the present invention is generally tubular in shape and has a catheter wall having an external surface and an internal surface, the wall defining an interior lumen of the catheter and an exterior, the wall extending between a proximal end and a distal end wherein the proximal end has a rim and is inserted into a body cavity or false space of a subject when in use for medical treatment and the distal end remains outside the body cavity or false space. The proximal and distal stabilizing elements are integral to the catheter wall and extend outwardly from the catheter wall or are present on opposite ends of a connecting member forming a stabilizer, the stabilizer disposed in the lumen of the catheter, wherein the proximal stabilizing element is positioned distal to the rim of the proximal end of the catheter.

Claims

1. A medical device, comprising:

a catheter having a catheter wall, the catheter wall having an external surface and an internal surface, the wall defining an interior lumen of the catheter and an exterior, the wall extending between a proximal end and a distal end, the proximal end having a rim, and the wall having one or more perforations;

a proximal stabilizing element extending outwardly from or outwardly through the wall near the proximal end; and

a distal stabilizing element extending outwardly from or outwardly through the wall near the distal end.

2. The medical device of claim 1, further comprising an introducer, the introducer having an introducer wall, the introducer wall having an external surface and an internal surface, the wall defining an interior lumen of the introducer and an exterior, the wall extending between a proximal end and a distal end of the introducer, wherein the catheter is at least partially disposed in the interior lumen of the introducer.

3. The medical device of claim 1, wherein at least one handle protrusion is present on the external surface of the introducer at or near the distal end of the introducer.

4. The medical device of claim 2, wherein the proximal end of the introducer is a sharp hollow needle-shaped opening.

5. The medical device of claim 2, wherein the proximal end of the introducer is hollow and non-sharp.

6. The medical device of claim 1, wherein the proximal and distal stabilizing elements are integral to the catheter wall and extend outwardly from the catheter wall.

7. The medical device of claim 1, wherein the proximal and distal stabilizing elements are present on opposite ends of a connecting member forming a stabilizer, the stabilizer disposed at least partially in the lumen of the catheter, wherein the proximal stabilizing element is positioned distal to the rim of the proximal end of the catheter.

8. The medical device of claim 7, wherein the connector is attached to the interior surface of the catheter lumen.

9. The medical device of claim 7, wherein the connector is not attached to the interior surface of the catheter lumen.

10. The medical device of claim 7, further comprising at least one opening in the catheter wall for egress of the proximal stabilizing element.

11. The medical device of claim 10, wherein at least two proximal stabilizing elements are present and at least two openings in the catheter wall for egress of the at least two proximal stabilizing elements.

12. The medical device of claim 1, further comprising a radiopaque x-ray marker disposed on or in the catheter wall.

13. The medical device of claim 1, further comprising a fiber optic camera attached to the catheter at or near the proximal end of the catheter.

14. The medical device of claim 1, further comprising a temperature sensor attached to the catheter at or near the proximal end of the catheter.

15. The medical device of claim 1, further comprising an LED disposed on the external surface of the catheter wall, the LED in electrical connection with a power source, the power source in operable connection with an activation switch.

16. A method of medical treatment of a subject in need thereof, comprising:

administering a catheter according to claim 1 to the subject.

17. The method of claim 16, wherein the catheter is at least partially contained in an introducer.

18. The method of claim 16, wherein the subject has a condition or disease characterized by undesired fluid production or accumulation and wherein treatment of the condition or disease comprises removal of the fluid via the catheter according to claim 1.

19. The method of claim 16, further comprising administration of a drug via the catheter according to claim 1.

20. A commercial package comprising a catheter according to claim 1.
