Abstract

Claims (47)

1. A catheter, comprising:

a body defining at least one longitudinal lumen therein;

a plurality of electrodes positioned radially outward of the at least one lumen;

a flexible member including a plurality of leads separated by insulating material;

an aperture corresponding to at least one first electrode of the plurality of electrodes; and

a connection disposed in the aperture;

wherein a lead of the plurality of leads is electrically connected to the at least one first electrode of the plurality of electrodes through only the connection; and

activation of at least two second electrodes of the plurality of electrodes generates an electrical field extending radially outward from only a portion of a circumference of the catheter.

2. The catheter of claim 1 , wherein a portion of the connection is radially outward of the lead and radially inward of the at least one first electrode.

3. The catheter of claim 2 , wherein the portion is transverse to the at least one lumen.

4. The catheter of claim 1 , wherein every electrode of the plurality of electrodes is electrically connected to a corresponding lead of the plurality of leads.

5. The catheter of claim 1 , wherein the plurality of electrodes includes a plurality of proximal electrodes and a plurality of distal electrodes;

the proximal electrodes include at least two longitudinally extending rows of electrodes; and

the distal electrodes include at least two longitudinally extending rows of electrodes.

6. The catheter of claim 1 , wherein each electrode of the plurality of electrodes is aligned with a corresponding aperture in a nonconductive material.

7. The catheter of claim 1 , wherein the flexible member is affixed to the body.

8. The catheter of claim 7 , wherein the flexible member is affixed to the body with an adhesive.

9. A catheter, comprising:

a body defining at least one longitudinal lumen therein;

a plurality of electrodes positioned radially outward of the at least one lumen, including a first row of electrodes positioned along a first length of the catheter and a second row of electrodes positioned along a second length of the catheter, wherein the second length is distal to the first length;

an aperture corresponding to an electrode of the plurality of electrodes;

a connection disposed in the aperture; and

a plurality of leads separated by insulating material;

wherein a lead of the plurality of leads is electrically connected to the electrode of the plurality of electrodes via the connection;

wherein the first row of electrodes has a first circumferential position on the catheter, and the second length of the catheter does not include an electrode at the first circumferential position.

10. The catheter of claim 9 , wherein the second row of electrodes has a second circumferential position on the catheter, and the first length of the catheter does not include an electrode at the second circumferential position.

11. The catheter of claim 9 , wherein the first length and the second length do not overlap.

12. The catheter of claim 11 , wherein the second length is distal to the first length.

13. The catheter of claim 9 , wherein a lead of the plurality leads is electrically connected to an electrode of the second row of electrodes and electrically insulated from each electrode of the first row of electrodes.

14. The catheter of claim 9 , wherein a longitudinal distance between a distalmost electrode of the first row of electrodes and a proximalmost electrode of the second row of electrodes is greater than a longitudinal distance between any two adjacent electrodes of the first row of electrodes, and the longitudinal distance between the distalmost electrode of the first row of electrodes and the proximalmost electrode of the second row of electrodes is greater than a longitudinal distance between any two adjacent electrodes of the second row of electrodes.

15. A catheter, comprising:

a body defining a longitudinal lumen therein;

a plurality of electrodes positioned radially outward of the lumen; and

a plurality of leads separated by insulating material;

an aperture corresponding to a first electrode of the plurality of electrodes;

a connection disposed in the aperture, wherein a portion of the connection is transverse to the at least one longitudinal lumen; and

a chip configured to interface with a controller, wherein the controller is external to the catheter, and the controller is configured to send electrical signals to one or more electrodes of the plurality of electrodes;

wherein a lead of the plurality of leads is electrically connected to the first electrode of the plurality of electrodes via the connection; and

wherein, upon receipt of a signal from the controller, the first electrode is configured to emit an electrical field extending radially outward from only a portion of a circumference of the catheter.

16. The catheter of claim 15 , wherein a portion of the connection is radially outward of the lead and radially inward of the electrode.

17. The catheter of claim 15 , further comprising a flexible member affixed to the body, wherein the flexible member includes the plurality of leads.

18. The catheter of claim 15 , wherein:

the electrode is positioned along a first length of the catheter;

the plurality of electrodes further includes a second row of electrodes positioned along a second length of the catheter;

wherein the electrode has a first circumferential position on the catheter, and the second length of the catheter does not include an electrode at the first circumferential position; and

the second length is distal to the first length.

19. The catheter of claim 15 , wherein the lead of the plurality of leads is electrically connected to the at least one first electrode of the plurality of electrodes through only the connection.
