Abstract
An injection device includes a carrier, a needle, a driver coupled to the needle, the driver being slidable relative to the carrier between a retracted configuration and a deployed configuration, a shuttle configured to move the driver between the retracted configuration and the deployed configuration, and a stop configured to move from a first configuration to a second configuration, wherein the stop is configured to maintain the driver in the deployed configuration, and movement of the stop from the first configuration to the second configuration allows the shuttle to move the driver from the deployed configuration to the retracted configuration.
