Abstract

A needle structure for communicating media to or from a patient includes a hollow shaft having two ends and a longitudinal dimension between the two ends. A passage is provided along at least a portion of its longitudinal dimension for conveying a flowable media. The shaft has at least one bend along its longitudinal dimension to dampen motion of one end of the needle relative to the other end of the needle.

Claims

1. A needle structure for communicating media to or from a patient, the needle structure comprising a hollow needle having a longitudinal dimension, a passage along at least a portion of its longitudinal dimension for conveying a flowable medium and at least one bend along its longitudinal dimension.

2. A needle structure according to claim 1, wherein the hollow needle has a plurality of bends along its longitudinal dimension.

3. A needle structure according to claim 1, wherein one side of the needle is affixed to a reservoir containing infusion media and the other side of the needle has a sharp end for penetrating the skin of a user.

4. A needle structure according to claim 3, wherein the needle has a plurality of right-angle bends along its longitudinal dimension that dampen movements of the end of the needle that is affixed to the reservoir with respect to the sharp end of the needle.

5. A needle structure according to claim 3, wherein the needle has at least one loop along its longitudinal dimension that dampen movements of the end of the needle that is affixed to the reservoir with respect to the sharp end of the needle.

6. A needle structure according to claim 3, wherein the needle has a plurality of coiled loops along its longitudinal dimension that dampens movements of the end of the needle that is affixed to the reservoir with respect to the sharp end of the needle.

7. A needle structure according to claim 1, wherein the needle has two ends and a plurality of right-angle bends along its longitudinal dimension that dampen movements of one end of the needle with respect to the other end of the needle.

8. A needle structure according to claim 1, wherein the needle has two ends and at least one loop along its longitudinal dimension that dampen movements of one end of the needle with respect to the other end of the needle.

9. A needle structure according to claim 1, wherein the needle has two ends and a plurality of coiled loops along its longitudinal dimension that dampen movement of one end of the needle with respect to the other end of the needle.

10. A needle for selective introduction into a user, comprising a hollow tube having a longitudinal dimension a sharp end and a second end, a passage along at least a portion of its longitudinal dimension for conveying a flowable medium, the hollow tube having at least one nonlinear segment for dampening movements of the second end of the hollow tube relative to the sharp end of the hollow tube.

11. A needle according to claim 10, wherein the at least one nonlinear segment comprises a plurality of bends along a portion of the longitudinal dimension of the hollow tube.

12. A needle according to claim 11, wherein the at least one nonlinear segment comprises a plurality of right-angle bends along a portion of the longitudinal dimension of the hollow tube.

13. A needle according to claim 11, wherein the at least one nonlinear segment comprises a plurality of coiled loops along a portion of the longitudinal dimension of the hollow tube.

14. A needle according to claim 10, wherein the at least one nonlinear segment comprises at least one right angle bend along a portion of the longitudinal dimension of the hollow tube.

15. A needle according to claim 10, wherein the at least one nonlinear segment comprises at least one loop along a portion of the longitudinal dimension of the hollow tube.

16. A delivery device for delivering infusion media to a user, the delivery device comprising a reservoir for containing an infusion media and a needle for selective introduction into a user, wherein the needle comprises a hollow tube having a longitudinal dimension a dispensing end and a second end, a passage along at least a portion of its longitudinal dimension in flow communication with the reservoir for conveying a flowable media from the reservoir toward the dispensing end of the hollow tube, the hollow tube having at least one nonlinear segment for dampening movements of the reservoir or the second end of the hollow tube relative to the dispensing end of the hollow tube.

17. A device according to claim 16, wherein the at least one nonlinear segment of the hollow tube comprises a plurality of bends along a portion of the longitudinal dimension of the hollow tube.

18. A device according to claim 17, wherein the at least one nonlinear segment of the hollow tube comprises a plurality of right-angle bends along a portion of the longitudinal dimension of the hollow tube.

19. A device according to claim 17, wherein the at least one nonlinear segment of the hollow tube comprises a plurality of coiled loops along a portion of the longitudinal dimension of the hollow tube.

20. A device according to claim 16, wherein the at least one nonlinear segment comprises at least one right angle bend along a portion of the longitudinal dimension of the hollow tube.

21. A device according to claim 16, wherein the at least one nonlinear segment comprises at least one loop along a portion of the longitudinal dimension of the hollow tube.
