The piezoelectric array is activated to pump the substance from the storage chamber to the dispensing chamber.

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.

Abstract: An ophthalmic injection system has a tip segment attachable to and removable from limited reuse assembly. The tip segment includes a flexible chamber for receiving a quantity of a substance, a piezoelectric array located near the flexible chamber, a needle fluidly coupled to the flexible chamber, and a first housing at least partially enclosing the flexible chamber and the piezoelectric array. The limited reuse assembly includes a power source for providing power to the piezoelectric array, a controller for controlling the power source, and a second housing at least partially enclosing the power source and the controller. The piezoelectric array is activated to compress the flexible chamber and dispense the substance from the flexible chamber.

Abstract: An ophthalmic injection device has a dispensing chamber housing, a plunger, a needle fluidly coupled to a dispensing chamber, a temperature control device, a power source for providing power to the temperature control device, a controller for controlling the temperature control device, and a mechanical linkage mechanism. The interior surface of the dispensing chamber housing partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. A plunger shaft is coupled to the plunger. The temperature control device can alter the temperature of the substance contained therein. The mechanical linkage mechanism has at least two pivots and at least two shafts and transfers force from a lever to the plunger.

Abstract: An injection device includes a dispensing chamber, a plunger, a controller, a memory device resistant to sterilization, and a housing at least partially enclosing the dispensing chamber and the plunger. The dispensing chamber has an inner surface and an outer surface. The inner surface defines a cavity for receiving a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber, is capable of sliding in the cavity of the dispensing chamber, and is fluidly sealed to the inner surface of the dispensing chamber. The controller controls the operation of the injection device. The controller reads dosage data from the memory device and operates the injection device to deliver a dosage corresponding to the dosage data.

Abstract: A technique can be used increase the flow of fluid through the trabecular meshwork. The fluid pulses can be focused, thereby perforating the trabecular meshwork, or applied over a larger area so as to stimulate the trabecular meshwork for improved fluid transport. In addition, the pulses of the irrigating fluid can clean away material, such as iris pigment, that may be blocking or clogging the trabecular meshwork. Such a technique may be practiced using the tip of the present invention and commercially available surgical handpieces.
