Devices, systems and methods for medicament delivery
First Claim
1. An apparatus, comprising:
- a housing defining a first cavity and a second cavity, a longitudinal axis defined by the first cavity offset from a longitudinal axis defined by the second cavity, a distal end portion of the housing defining a first opening in fluid communication with the first cavity and a second opening in fluid communication with the second cavity;
a medicament injector movably disposed within the first cavity, the medicament injector including a medicament container and a needle;
an energy storage member disposed within second cavity, the energy storage member configured to produce a force to move the medicament injector to an injection position in which a portion of the needle is disposed through the first opening; and
an actuation member configured to actuate the energy storage member when the actuation member is moved from a first position to a second position, a first portion of the actuation member disposed within the second cavity when the actuation member is in the first position, a second portion of the actuation member disposed through the second opening when the actuation member is in the first position.

Abstract
An apparatus includes a housing, a medicament container and an actuator. The actuator includes a release member and an energy storage member having a first position and a second position. In the first position, the energy storage member has a first potential energy. In the second position the energy storage member has a second potential energy. The energy storage member is configured to convert a portion of the first potential energy into kinetic energy when moved from the first position to the second position to move the medicament container within the housing. The energy storage member has a longitudinal axis offset from a longitudinal axis of the medicament container. The release member is configured to selectively deploy the energy storage member from its first position to its second position.
