Patent ID: 8298187

Claim:
A medical device comprising: an elongate cannula comprising a distal end portion, a proximal end portion, and a lumen defined therethrough, an outer circumferential surface defining an upper portion, a right side portion, a bottom portion, and a left side portion each substantially equally spaced from their respective neighboring portion around the circumferential surface of the cannula, the cannula further comprising a plurality of apertures disposed through the distal end portion to provide communication from the lumen, a first of the plurality of apertures disposed on the right side portion, a second of the plurality of apertures disposed on the bottom portion, and a third of the plurality of apertures disposed on the left side portion, and a visually perceptible indicator that is configured to allow the cannula to be positioned at an appropriate rotational position within a patient, wherein the visually perceptible indicator is a line applied to the outer circumferential surface of the cannula parallel to a longitudinal axis thereof and is disposed at a circumferential position such that a central axis of the line parallel to the longitudinal axis is disposed between the upper portion and one of the right or left side portions of the outer circumferential surface of the cannula; a plurality of injection needles disposed within the lumen, each comprising a distal portion disposed in alignment with one of the first, second, and third apertures and a proximal end portion; and a first handle fixed with respect to the cannula and a second handle disposed in conjunction with the first handle and fixed to the proximal end portion of each of the plurality of needles, the first handle translatable with respect to the second handle to translate the plurality of needles from a first position where the distal portions of each of the plurality of needles are disposed within the lumen of the cannula, and a second position where the distal portion of each of the plurality of needles extends out of the lumen through their respective aperture.
