Abstract

A catheter having a catheter body having a proximal end and a distal end and a proximal portion fixedly connected to the proximal end is disclosed. A magnet is disposed around the catheter body distally of the proximal portion.

Claims

1. A catheter comprising:

a catheter body having a proximal end and a distal end;

a proximal portion fixedly connected to the proximal end; and

a magnet disposed around the catheter body distally of the proximal portion.

2. The catheter according to claim 1, wherein the magnet is annularly shaped.

3. The catheter according to claim 2, wherein only one of a north pole and a south pole of the magnet is disposed proximate to the catheter body.

4. The catheter according to claim 3, wherein only the south pole of the magnet is disposed proximate to the catheter body.

5. The catheter according to claim 1, wherein the proximal portion comprises a hub.

6. The catheter according to claim 1, further comprising a cuff disposed on the body distal of the magnet.

7. The catheter according to claim 6, wherein the magnet is slidably disposed along the body between the cuff and the proximal portion.

8. The catheter according to claim 1, wherein the magnet has a magnetic strength of between 700 and 1000 Gauss.

9. The catheter according to claim 1, wherein the magnet is encased in an annular casing.

10. The catheter according to claim 1, wherein the catheter body comprises a plurality of lumens.

11. The catheter according to claim 1, further comprising a hub connecting the proximal end and the distal end.

12. A catheter comprising:

a catheter body having a proximal end and a distal end;

a hub connecting the proximal end and the distal end; and

a magnet disposed within the hub.

13. The catheter according to claim 12, wherein the catheter body comprises a plurality of lumens.

14. The catheter according to claim 13, wherein the magnet comprises a like plurality of magnets, wherein each of the plurality of magnets is annularly disposed around a respective each of the plurality of lumens.

15. The catheter according to claim 14, wherein each of the plurality of magnets has a magnetic strength of between 700 and 1000 Gauss.

16. The catheter according to claim 14, wherein only one of a north pole and a south pole of each of the plurality of magnets is disposed proximate to each of the respective plurality of lumens.

17. The catheter according to claim 16, wherein only the south pole of each of the plurality of magnets is disposed proximate to each of the respective plurality of lumens.
