Patent ID: 7648483

Claim:
An apparatus, comprising: a housing having a distal end portion and a proximal end portion; a needle configured to move between a first position and a second position, in the first position the needle is contained within the housing, in the second position at least a portion of the needle extends from the distal end portion of the housing; an energy storage member having a first configuration and a second configuration, the energy storage member configured to produce a force when moved between its first configuration and its second configuration to move the needle from its first position to its second position; an actuator configured to move the energy storage member from its first configuration to its second configuration, the actuator including a first actuation member disposed within the housing and a second actuation member coupled to the distal end portion of the housing; and a locking member configured to be movably coupled to the distal end portion of the housing such that the locking member can be moved between a first position and a second position, the locking member including a protrusion configured to extend through an opening defined by the second actuation member and engage a portion of the first actuation member when the locking member is in its first position to prevent the actuator from moving the energy storage member to the second configuration.
