International Classification:

A61B019/00

US Classification:

128898, 604541, 606107, 606166

Abstract:

Featured is a device for puncturing tissue of a body, such as the lamina cribosa and methods for treating a CVRO with such a puncturing device. The puncturing device includes a puncture member being generally configured and arranged to locally disrupt tissue proximal an area of the puncture site, to minimize the potential for damage to body parts or tissue immediately adjacent to this area of the puncture site and to facilitate perforation of the tissue at the puncture site. When the lamina cribosa is being punctured, the puncture member is more particularly configured and arranged to locally disrupt connective tissue of the lamina cribosa proximal to and surrounding the central retinal vein while minimizing the potential for structural damage to the central retinal vein. In an exemplary embodiment, the lamina cribosa is repeatedly punctured to strip/locally disrupt connective tissue surrounding the central retinal vein.

International Classification:

A61F 9/00

US Classification:

606107, 604 30, 600561

Abstract:

A surgical system includes a surgical instrument, an aspiration flow rate measurement device, a vacuum force measurement device, and an indicator. The surgical instrument has an aspiration portion and is located in a media type. The aspiration flow rate measurement device is configured to measure the flow rate generated by the aspiration portion. The vacuum force measurement device is configured to measure the vacuum force generated by the aspiration portion. The indicator provides an indication of the media type in which the surgical instrument is located. The indication is based on aspiration flow rate measurement information, vacuum force measurement information, and an operation and configuration of the surgical instrument.

International Classification:

A61M 35/00

US Classification:

604294, 604113, 604291

Abstract:

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.

International Classification:

A61M 35/00

US Classification:

604290000

Abstract:

A method of injecting a substance into an eye is disclosed. A connection between a disposable tip segment and a limited reuse assembly is recognized. A temperature control device is activated to alter the temperature of a substance contained in a dispensing chamber. Dosage information is read. In response to the dosage information, a mechanical linkage interface is advanced to advance a plunger to expel the substance from the dispensing chamber. The mechanical linkage interface is retracted without substantially retracting the plunger to prevent reflux of the substance. Reuse of the disposable tip segment is prevented. The removal of the disposable tip segment from the limited reuse assembly is recognized.

US Classification:

320137, 3405728, 235375

Abstract:

A safety charging system for a battery-operated surgical hand includes a charging base, a battery pack, and control logic. The charging base has an RFID reader antenna disposed near a top surface of the charging base and charge circuitry for charging the battery. The battery pack has the battery used with the hand piece and an RFID tag antenna disposed near a bottom surface of the battery pack. The control logic determines if the battery should be charged based on a data point read by the RFID reader antenna.

International Classification:

A61F 9/007
G05D 23/19

US Classification:

604 67, 700300

Abstract:

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.
