Abstract
A tissue mapping injection device suitable for use during a lymphatic breast mapping procedure is provided. The device includes a housing having an elongated body portion extending distally therefrom. A plunger is slidably positioned within the housing. A connector rod is secured to the forward end of the plunger and extends distally through the elongated body portion. The plunger and the connector rod define a fluid delivery channel. A plurality of needles are secured to the distal end of the connector rod. Each of the needles is constructed from a shape memory material and defines a fluid injection channel which communicates with the fluid delivery channel. The plunger is movable from a retracted position wherein the needles are positioned within the elongated body portion to an advanced position wherein the needles extend outwardly from the distal end of the elongated body portion.
