Abstract

Disclosed embodiments provide an apparatus and method for converting a catheter to a magnetic catheter and using the magnetic catheter by coupling a clamp with magnetizable components to a catheter.

First claim

1 . An apparatus comprising:
a clamp having magnetizable components which clamps to a catheter, wherein the clamped portion of the catheter is configured to be inserted into a body, and wherein an application of a magnetic field to a body manipulates the catheter by acting on at least one of the magnetizable components within the clamp.

2 . The apparatus of claim 1 , wherein the clamp further comprises hinges.

3 . The apparatus of claim 1 , wherein the clamp further comprises interlocking components and the magnetizable components are integrally formed with the interlocking components or affixed to the interlocking components.

4 . The apparatus of claim 3 , wherein the clamp further comprises locking components configured to releasably or permanently lock the interlocking components together around the catheter.

5 . The apparatus of claim 1 , wherein at least one of magnetizable components is configured to be controlled independently by the application of the magnetic field.

6 . The apparatus of claim 1 , wherein the magnetizable components are pre-polarized.

7 . A method of converting a catheter into a magnetic catheter and using the magnetic catheter comprising:
affixing a clamp containing magnetizable components to a catheter for use when an external magnetic field is applied to a body.

8 . The method of claim 7 further comprising delivering therapy to tissues in a body via the magnetic catheter.

9 . The method of claim 8 wherein the therapy is lavage.

10 . The method of claim 7 wherein tissue is removed from a body via the magnetic catheter.

11 . The method of claim 7 , further comprising using an external magnetic field to image the magnetic catheter in the body.

12 . The method of claim 7 , where the affixing of the clamp is performed in the field.

13 . The method of claim 7 , where manipulation of the catheter is done by a system that also provides images of the catheter.

14 . The method of claim 13 , where the manipulation is performed robotically.

15 . The method of claim 7 , wherein the clamp is affixed via locking components configured to releasably or permanently lock interlocking components together around the catheter.
