| 20080234625 | Fuse Assembly For Single Use Medical Device - A disposable injection device includes a dispensing chamber, a plunger, a fuse in series with a light, and a housing. 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 housing at least partially encloses the dispensing chamber and the plunger. After the substance has been delivered from the dispensing chamber, the fuse is blown causing the light to go out and disabling the device. | 09-25-2008 |
| 20090036846 | Ophthalmic Injection System - An ophthalmic injection system has a tip segment attachable to and removable from a limited reuse assembly. The tip segment has a dispensing chamber housing, a plunger, a needle, a temperature control device, a thermal sensor, and a first housing at least partially enclosing the dispensing chamber housing, the temperature control device and the plunger. The limited reuse assembly has an actuator with a shaft, a power source for providing power to the actuator, a controller for controlling the actuator, a mechanical linkage interface, and a second housing at least partially enclosing the power source, the controller, and the actuator. The mechanical linkage interface is coupled to the actuator shaft and has a mating surface on one end. The substance is injected after the temperature of the substance is altered. | 02-05-2009 |
| 20090287150 | Universal Rechargeable Limited Reuse Assembly For Ophthalmic Hand Piece - The present invention is a universal limited reuse assembly for an ophthalmic hand piece having a power source for providing power to a tip segment, a controller for controlling the operation of the tip segment, a motor with a shaft, a mechanical linkage interface located on an end of the shaft, an interface for connecting the limited reuse assembly to the tip segment, and a housing at least partially enclosing the power source, the controller, and the motor. The limited reuse assembly is connectable to and removable from two or more types of tip segments. Each of the two or more types of tip segments is configured to perform a different procedure. | 11-19-2009 |
| 20100030136 | Ophthalmic Injection Device Including Dosage Control Device - An injection device includes a dispensing chamber, a plunger, a controller, a temperature control device, and a memory device. 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 temperature control device at least partially surrounds the dispensing chamber. The memory device has a parameter stored on it. The controller uses the parameter from the memory device to operate the injection device. | 02-04-2010 |
| 20100106083 | Method of Operating Ophthalmic Hand Piece with Disposable End - The present invention is a method of operating an ophthalmic hand piece. A connection between a tip segment and a limited reuse assembly is recognized. A type of tip segment connected to the limited reuse assembly is determined. Dosage information is received. A first input is received. In response to the first input, a heater is activated to heat a substance contained in a dispensing chamber. After the substance has reached a desired temperature range, the dosage information is used to control a distance a plunger travels. A second input is received. In response to the second input a motor is activated, and the drug is delivered into the eye. | 04-29-2010 |
| 20100211044 | BATTERY OPERATED SURGICAL HAND PIECE WITH DISPOSABLE END - The present invention is an ophthalmic injection system with a limited reuse assembly and a tip segment. The tip segment is connectable to and removable from the limited reuse assembly. The tip segment includes a dispensing chamber, a plunger, and a housing. The dispensing chamber holds a quantity of a substance to be injected into an eye. The proximate end of the plunger has a first mechanical linkage interface. The limited reuse assembly of the ophthalmic injection system has a power source, a controller, a motor, a second mechanical linkage interface located on an end of the motor shaft; and a second housing. The first mechanical linkage interface is mateable with the second mechanical linkage interface such that when the tip segment is connected to the limited reuse assembly, the first mechanical linkage interface mates with the second mechanical linkage interface so that motion of the shaft results in motion of the plunger. | 08-19-2010 |
| 20110022117 | Cytokine Production Via Electrical Stimulation to Treat Glaucoma - The present invention is a method of treating glaucoma by electrically stimulating the ciliary muscle to produce shear stress on the trabecular meshwork sufficient for cytokine production. A device for electrically stimulating the ciliary muscle includes a pair of electrodes configured to provide a voltage to the ciliary muscle. The electrodes are coupled to a voltage source. A controller operates to apply the voltage to the ciliary muscle. | 01-27-2011 |
| 20110230877 | Pulsed Electric Field Probe for Glaucoma Surgery - A small gauge pulsed electric field/aspirator probe. The probe has a generally cylindrical cannula with a generally smooth distal end. A port is located near a distal end of the cannula on a side of the cannula. A pair of electrodes is located at the port. An electric pulse generator is coupled to the pair of electrodes. A distance between the distal end of the cannula and the port is approximately equal to the distance between a back wall of Schlemm's canal and a trabecular meshwork in a human eye. The electric pulse generator applies a pulsed electric field to the pair of electrodes sufficient to dissociate protein bonds that hold the trabecular meshwork together. | 09-22-2011 |
