1. A trocar assembly for delivering a payload into tissue, comprising:
- a primary housing;
a cannula defining a lumen and having a proximal portion received in the housing and a distal portion extending from the housing;
a payload disposed in an initial position within the housing and in communication with the cannula;
an actuator for advancing the payload through the lumen to exit via the distal portion of the cannula;
a trocar comprising a distal end with a tip for piercing tissue and a proximal end in communication with a shifter for positioning the trocar, wherein, in an extended position, the trocar occupies the lumen and extends past the distal end of the cannula, and, in a retracted position, the trocar is sufficiently retracted from the lumen such that the payload can pass through the lumen to exit via the distal end of the cannula.
