Abstract: An injection system includes an injection system body defining a proximal opening at a proximal end thereof and a distal needle interface at a distal end thereof. The system also includes proximal and distal stopper members disposed in the injection system body, forming a proximal drug and a distal drug chamber. The system further includes a plunger member configured to insert the proximal stopper member relative to the injection system body. Moreover, the system includes a valve forming an openable barrier between the distal needle interface and the distal drug chamber. The valve includes an outer member including a distal diaphragm, and an inner member. The distal diaphragm is configured to elastically deform distally away from the inner member with increased pressure in the distal drug chamber to allow flow from the distal drug chamber to the distal needle interface.

Abstract: A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is retractable into plunger interior upon manipulation of the plunger member to actuate the energy-storage member latching member.

Abstract: A method for preparing a pre-filled multi-chamber injection system includes providing an injection system body, the injection system body defining an open proximal end, a body interior, and an open distal end. The method also includes introducing a first substance into a distal end of the body interior. The method further includes disposing a distal stopper member in the body interior, the distal stopper member and the injection system body defining proximal and distal chambers in the body interior. Moreover, the method includes introducing a second substance into the body interior. In addition, the method includes disposing a proximal stopper member in the body interior. The method also includes inserting an elongate member at least partially into the body interior, the elongate member having a plurality of flow channels for fluidly coupling the proximal and distal chambers. The method further includes coupling a plunger member to the proximal stopper member.

Abstract: A system for mixing drug products and injecting includes a syringe body, proximal and distal stopper members disposed in the syringe body, a plunger member, and a needle hub assembly coupled to the distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber between there between and a distal drug chamber between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention feature, an energy-storage member, and an energy-storage member latching member all disposed in disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body. The needle is at least partially retractable into plunger interior upon manipulation of the plunger member relative to the syringe body.
