Claim Text:
1. A needle structure for communicating fluid to a patient from an external fluid reservoir configured to contain a flowable fluid and having a pierceable septum external to the patient, the needle structure comprising a hollow needle having a longitudinal dimension, a first end affixed to the fluid reservoir, and a second end having a sharp end for inserting the needle into the patient, wherein force applied to the first end of the needle pushes the needle through the pierceable septum to position the needle in fluid flow communication with the fluid reservoir and to insert the second end of the needle into the patient, the hollow needle further having a generally straight section extending along the longitudinal dimension adjacent the first end, the generally straight section passing through the pierceable septum external to the patient, a passage along at least a portion of its longitudinal dimension for conveying the flowable fluid to the patient and at least one bend along its longitudinal dimension between the generally straight section and the second end that dampens movements of the second end with respect to the first end, the needle being flexible at the at least one bend and flexes to dampen the transfer of motion from the second end of the needle to the generally straight section of the needle.
