Abstract
An injection system comprising a syringe barrel; a first sealing element and a second sealing element moveably disposed in the syringe barrel; an injection chamber between them; a puncture element extending from the first sealing element to deliver an injection agent from the injection chamber into a biological space, wherein one or more of the syringe barrel, the first or the second sealing element are configured to prevent proximal movement of the first sealing element past a pre-selected location, while allowing the second sealing element to come in contact with the first sealing element, the system is configured such that, when a force is applied on the second sealing element in a distal direction, in response to a first opposing force, the puncture element advances and in response to a second opposing force, the puncture element remains stationary and the injection agent is conveyed through the puncture element.
