摘要：
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.
