Abstract
An ophthalmic injection device has a dispensing chamber housing, a needle fluidly coupled to a dispensing chamber, a power source for providing current to the dispensing chamber housing, a controller for controlling the power source, and a housing at least partially enclosing the dispensing chamber housing, the power source, and the controller. The dispensing chamber housing is made of a shape memory alloy and has an inner surface defining a dispensing chamber for receiving a quantity of a substance. The controller directs a first current to the dispensing chamber housing to heat the substance contained in the dispensing chamber and a second current to the dispensing chamber housing to alter the shape of the dispensing chamber housing to deliver the substance.
