Abstract

A catheter system utilizing one or more sensors is described. The catheter can be used as part of an embolic coil system, guidewire system, or combined embolic coil/guidewire system where the devices interact with the catheter system. A variable detachment embolic coil system and guidewire system are also described.

Claims (29)

1. A delivery system, comprising:

a catheter; and

an embolic structure releasably attached to the catheter, the embolic structure including a pair of conductive sleeves and a degradable portion between the pair of conductive sleeves; and,

wherein, upon an electrical current flowing through a completed electrical circuit, the embolic structure is released from the catheter.

2. The delivery system of claim 1 , wherein the pair of conductive sleeves comprises a proximal conductive sleeve and a distal conductive sleeve.

3. The delivery system of claim 1 , wherein the embolic structure is comprised of an embolic coil.

4. The delivery system of claim 1 , wherein the embolic structure includes a link and a pair of segments.

5. The delivery system of claim 4 , wherein the link is positioned between the pair of segments of the embolic structure.

6. The delivery system of claim 1 , wherein the catheter includes a first contact and a second contact.

7. The delivery system of claim 6 , wherein the electrical circuit is completed when the first contact and the second contact of the catheter are in electrical communication with a first conductive sleeve and a second conductive sleeve of the pair of conductive sleeves.

8. The delivery system of claim 7 , wherein the degradable portion degrades in response to current flowing through the completed circuit such that a pair of segments of the embolic structure detach from each other.

9. The delivery system of claim 1 , wherein the degradable portion is a monofilament.

10. The delivery system of claim 1 , wherein the degradable portion is a fuse.

11. The delivery system of claim 1 , further comprising a user interface including a button which, once actuated, initiates a detachment sequence to cause a pair of segments of the embolic structure to detach from each other.

12. The delivery system of claim 1 , further comprising a user interface, wherein a video or audio cue is produced from the user interface when the catheter is in electrical communication with the pair of conductive sleeves.

13. A delivery system, comprising:

a catheter including a pair of contacts; and

an embolic structure releasably attached to the catheter, the embolic structure including a pair of conductive sleeves and a degradable portion between the pair of conductive sleeves; and,

wherein, upon an electrical current flowing through a completed electrical circuit between the pair of contacts of the catheter and the pair of conductive sleeves of the embolic structure, the embolic structure is released from the catheter.

14. The delivery system of claim 13 , wherein the embolic structure includes two segments and a link.

15. The delivery system of claim 14 , further comprising an insulating member positioned between the two segments of the embolic structure.

16. The delivery system of claim 14 , wherein the link is positioned between the two segments of the embolic structure.

17. The delivery system of claim 14 , wherein the embolic structure is comprised of an embolic coil.

18. The delivery system of claim 17 , wherein at least part of the link is positioned within the segments of the embolic coil.

19. The delivery system of claim 13 , wherein the embolic structure includes a heater coil.

20. A delivery system, comprising:

a delivery means; and

an embolic means releasably attached to the delivery means, the embolic means including a pair of conductive sleeves and a degradable portion between the pair of conductive sleeves; and,

wherein, upon an electrical current flowing through a completed electrical circuit, the embolic means is released from the delivery means.
