Abstract

Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary device in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.

Claims

1. An elongate medical device for penetrating tissue, comprising:

an elongate shaft having a proximal segment and a reduced diameter distal segment, the distal segment unitarily formed with the proximal segment;

a coil positioned around the distal segment;

a tip member fixedly securing a distal end of the coil to the distal segment; and

a distal portion of the distal segment extending distal of the distal end of the coil and extending distal of a distalmost end of the tip member;

wherein the distal portion of the distal segment defines a probe adapted and configured to pierce tissue.

2. The elongate medical device of claim 1, wherein the probe defines a distalmost end of the elongate medical device.

3. The elongate medical device of claim 1, wherein the probe is exposed from all other components of the elongate medical device.

4. The elongate medical device of claim 1, wherein the elongate shaft includes a tapered segment between the proximal segment and the distal segment.

5. The elongate medical device of claim 4, wherein a proximal end of the coil is secured to the tapered segment of the elongate shaft.

6. The elongate medical device of claim 5, wherein the proximal segment has a constant diameter.

7. The elongate medical device of claim 6, wherein the distal segment has a constant diameter.

8. The elongate medical device of claim 1, wherein the probe extends distally beyond all other components of the elongate medical device by a distance that is greater than 0.003 inches.

9. The elongate medical device of claim 8, wherein the probe extends distally beyond all other components of the elongate medical device by a distance that is less than 0.012 inches.

10. The elongate medical device of claim 1, wherein the elongate shaft comprises a bend disposed between the proximal segment and the distal portion of the distal segment such that the distal portion of the distal segment extends at an angle to the proximal segment, the angle being greater than 90 degrees and less than 180 degrees.

11. The elongate medical device of claim 10, wherein the angle is greater than 120 degrees and less than 150 degrees.

12. An elongate medical device for penetrating tissue, comprising:

an elongate shaft having a proximal segment and a reduced diameter distal segment, the distal segment unitarily formed with the proximal segment;

a tubular component positioned around and fixedly secured to the distal segment of the elongate shaft; and

a distal portion of the distal segment extending distal of a distal end of the tubular component and forming a probe adapted and configured to pierce tissue;

the probe being exposed from all other components of the elongate medical device and defining a distalmost end of the elongate medical device.

13. The elongate medical device of claim 12, wherein the elongate shaft includes a tapered segment between the proximal segment and the distal segment.

14. The elongate medical device of claim 13, wherein a proximal end of the tubular component is secured to the tapered segment of the elongate shaft.

15. The elongate medical device of claim 14, wherein the proximal segment has a constant diameter.

16. The elongate medical device of claim 15, wherein the distal segment has a constant diameter.

17. The elongate medical device of claim 12, wherein the probe extends distally beyond all other components of the elongate medical device by a distance that is greater than 0.003 inches.

18. The elongate medical device of claim 17, wherein the probe extends distally beyond all other components of the elongate medical device by a distance that is less than 0.012 inches.

19. The elongate medical device of claim 12, wherein the elongate shaft comprises a bend disposed between the proximal segment and the distal portion of the distal segment such that the distal portion of the distal segment extends at an angle to the proximal segment, the angle being greater than 90 degrees and less than 180 degrees.

20. The elongate medical device of claim 19, wherein the angle is greater than 120 degrees and less than 150 degrees.
