Abstract

A device for introduction into a vessel including a main elongated element having a main elongated element proximal end and a main elongated element distal end, a balloon positioned at the main elongated element distal end, and a core wire attached to the device at a core wire attachment point and including an internal core wire portion positioned in the main elongated element and an external core wire portion positioned distally with respect to the internal core wire portion and positioned in parallel relation and external to the balloon.

Claims

1. A device for introduction into a vessel, the device comprising:

a main elongated element having a main elongated element proximal end and a main elongated element distal end;

a balloon positioned at the main elongated element distal end; and

a core wire bonded to the device at a core wire attachment point, comprising an internal core wire portion positioned in the main elongated element and an external core wire portion positioned distally with respect to the internal core wire portion and positioned in parallel relation and external to the balloon.

2. The device according to claim 1, further comprising an auxiliary elongated element having an auxiliary elongated element proximal end and an auxiliary elongated element distal end, the auxiliary elongated element distal end positioned proximal to the balloon.

3. The device according to claim 2, further comprising a distal connecting element positioned at a distal end of the balloon to receive a guidewire during use, the balloon being pushed along the guidewire upon application of a pushing force to the proximal end of the main elongated element.

4. The device according to claim 3, wherein the distal connecting element is at a rotational distance from the auxiliary elongated element, and wherein the distal connecting element and the auxiliary elongated element are at rotational distances from the external core wire portion.

5. The device according to claim 4, wherein the rotational distances are between 60 and 120 degrees.

6. The device according to claim 3, wherein the distal connecting element is rotationally aligned with the auxiliary elongated element.

7. The device according to claim 1, wherein the balloon is a fixed wire balloon.

8. The device according to claim 2, wherein the auxiliary elongated element is positioned at least partially inside of the main elongated element.

9. The device according to claim 2, wherein the device is an over-the-wire catheter and wherein the auxiliary elongated element runs along an entire length of the device.

10. The device according to claim 9, further comprising an occlusion balloon positioned proximal to the auxiliary elongated element distal end.

11. The device according to claim 2, wherein the auxiliary elongated element proximal end is positioned at a point along the main elongated element such that a guidewire placed through the auxiliary elongated element may exit at the auxiliary elongated element proximal end for rapid exchange.

12. The device according to claim 1, further comprising a distal connecting element positioned at a distal end of the balloon to receive a guidewire during use, the balloon being pushed along the guidewire upon application of a pushing force to the proximal end of the main elongated element.

13. The device according to claim 1, wherein the external core wire portion further comprises a coil wrapped around at least a portion thereof, the coil-wrapped portion being positioned adjacent to the balloon.

14. The device according to claim 1, wherein the external core wire portion comprises at least one radiopaque marker.

15. The device according to claim 1, wherein the main elongated element comprises a flexible portion and wherein the internal core wire portion is positioned along an entire length of the flexible portion.

16. The device according to claim 1, wherein the main elongated element comprises a stiff proximal portion and a flexible distal portion, wherein the attachment point is at an interface between the stiff proximal portion and the flexible distal portion.

17. The device according to claim 16, wherein the stiff proximal portion comprises a hypotube in a proximal portion of the main elongate element.

18. The device of claim 16, comprising additional attachment points at a distal tip of the balloon and at a transition of the internal core wire portion to the external core wire portion.

19. The device of claim 1, wherein the attachment point is at a distal end of the balloon.

20. The device of claim 1, wherein the attachment point is at a proximal end of the device.
