DEVICES AND METHODS FOR DELIVERING MEDICAMENTS FROM A MULTI-CHAMBER CONTAINER
First Claim
1. An apparatus, comprising:
- a medicament container configured to be movably coupled to a carrier of a medicament delivery device, the carrier including a needle;
a first elastomeric member disposed within a proximal end portion of the medicament container;
a second elastomeric member disposed within the medicament container, the first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively defining, at least in part, a medicament volume; and
a stopper coupled to a distal end portion of the medicament container, the second elastomeric member, a second portion of the medicament container and the stopper collectively defining, at least in part, a vent volume, the stopper having a first retention portion and a second retention portion, the first retention portion configured to engage a first portion of the carrier to limit movement of the medicament container relative to the carrier when the medicament container is in a first position relative to the carrier, the second retention portion configured to engage a second portion of the carrier to limit movement of the medicament container relative to the carrier when the medicament container is in a second position relative to the carrier.

Abstract
An apparatus includes a medicament container, a first elastomeric member, a second elastomeric member and a stopper. The first and second elastomeric members are disposed within the medicament container. The first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively define a medicament volume. The stopper is coupled to a distal end portion of the medicament container. The second elastomeric member, a second portion of the medicament container and the stopper collectively define a vent volume. A first retainer of the stopper is configured to engage a first portion of a carrier to limit movement of the medicament container when in a first position. A second retainer of the stopper is configured to engage a second portion of the carrier to limit movement of the medicament container when in a second position.

10. An apparatus, comprising:
-
a medicament container configured to be movably coupled to a carrier of a medicament delivery device, the carrier including a needle; a first elastomeric member disposed within a proximal end portion of the medicament container; a second elastomeric member disposed within the medicament container, the first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively defining, at least in part, a medicament volume; and a stopper coupled to a distal end portion of the medicament container, the second elastomeric member, a second portion of the medicament container and the stopper collectively defining, at least in part, a vent volume, a retention portion of the stopper configured to engage a portion of the carrier to limit movement of the medicament container relative to the carrier when the medicament container is in a first position relative to the carrier, the stopper defining a needle volume within which the needle is disposed when the medicament container is in the first position, the retention portion and the portion of the carrier collectively forming a substantially fluid-tight seal such that the needle volume is fluidically isolated from a volume outside of the medicament container when the medicament container is in the first position. - View Dependent Claims (11, 12, 13)

14. An apparatus, comprising:
-
a carrier of a medicament delivery device, the carrier coupled to a needle; and a medicament container configured to be movably coupled to the carrier, the medicament container including; a first elastomeric member disposed within a proximal end portion of the medicament container; a second elastomeric member disposed within the medicament container such that the first elastomeric member, a first portion of the medicament container and the second elastomeric member collectively define a first medicament volume; a third elastomeric member disposed within the medicament container, the second elastomeric member, a second portion of the medicament container and the third elastomeric member collectively defining, at least in part, a second medicament volume; and a stopper coupled to a distal end portion of the medicament container, the third elastomeric member, a third portion of the medicament container and the stopper collectively defining, at least in part, a vent volume, the stopper configured to fluidically isolate the needle from the vent volume when the medicament container is in a first position relative to the carrier, the needle disposed through a portion of the stopper to fluidically couple the vent volume to the needle when the medicament container is in the second position, the needle disposed through a portion of the third elastomeric member to fluidically couple the second medicament volume to the needle when the medicament container is in a third position relative to the carrier.

15. A method, comprising
moving a medicament container having a first elastomeric member, a second elastomeric member and a third elastomeric member disposed therein from a first position to a second position relative to a carrier of a medicament delivery device such that a needle of the carrier pierces a stopper coupled to a distal end portion of the medicament container to place a vent volume in fluid communication with the needle, the vent volume defined, in part, between the third elastomeric member and the stopper; -
moving the second elastomeric member within the medicament container to convey a gas from a solid medicament volume to the vent volume, the solid medicament volume defined, in part, by the third elastomeric member and the second elastomeric member; and moving the medicament container to a third position relative to the carrier such that the needle of the carrier pierces the third elastomeric member to place the solid medicament volume in fluid communication with the needle. - View Dependent Claims (16, 17, 18, 19)
