Abstract: Disclosed are devices and methods for facilitating directed delivery of a medicament into a human organ of a patient. An apparatus to facilitate directed delivery of a medicament into a human organ of a patient may include a container configured to enclose the medicament, a needle having a passage therethrough and a sharp distalmost tip, and a needle guard at least partially surrounding a shaft of the needle. The needle guard may include a distal surface, wherein the sharp distalmost tip of the needle may be configured to extend through an opening in the distal surface. The needle guard may be moveable relative to the needle along an axis of the needle to control a distance from the distal surface to the distalmost tip of the needle.

Abstract: A drug delivery device is disclosed, wherein the device comprises a housing; a cap located at a proximal end of the housing, the cap including a first pair of deflectable arms and a second pair of deflectable arms; a product vessel arranged in the housing, and a needle coupled to a distal end of the product vessel; a plunger rod for dispensing a product from the product vessel, wherein the plunger rod is slidably received within the cap and partially disposed inside the product vessel; and a needle cover at least partially disposed in the housing, wherein the first pair of deflectable arms are configured to deflect radially inwards towards the plunger rod and the second pair of deflectable arms are configured to radially outwards away from the plunger rod.

Abstract: A drug delivery device is disclosed, wherein the device comprises a housing; a product container arranged in the housing; a plunger rod partially disposed inside the product container; and a thumb pad configured to receive a portion of the plunger rod, wherein the thumb pad and the plunger rod are configured to transition from a first state to a second state, wherein at the first state, the plunger rod is prevented from moving in a proximal direction, and at the second state, the plunger rod moves freely in a proximal direction.

Abstract: A vial adapter assembly that includes a housing, a first receptacle formed within the housing and configured to receive a first vial within the housing, and a second receptacle formed within the housing and configured to receive a second vial within the housing. An opening of the first receptacle and an opening of the second receptacle is in fluid communication with the upper surface of the housing. The vial adapter assembly includes a cap that is coupled and movable relative to the housing from a closed configuration to an open configuration. In the closed configuration, the cap is configured to cover the opening of the first receptacle and the opening of the second receptacle on the upper surface. In the open configuration, the cap is configured to uncover the opening of the first receptacle and the opening of the second receptacle, and expose the upper surface.
