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.

- 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.
- 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.
