### Device Description

The ESU-1 Electrosurgical Generator is a high frequency isolated generator that utilizes electrical current via an assortment of surgical devices to cut and coagulate different types of tissue. The ESU-1 Electrosurgical Generator features cutting up to 300 watts with 2 cut modes, including "Cut T", a blend mode with 4 levels, 3 coagulation modes and 4 bipolar modes with Auto Bipolar option. "Cut T" mode is a new feature that includes a timing feature which automatically ceases RF activation after a user selectable period of time that can be altered between 0.1 and 3.0 seconds. The RF activation for Cut T mode is initially pre-set at 2 seconds (Note: if the operator changed these settings, the generator will powerup with the mode and setting in which the operator last activated the generator). The generator offers 2 monopolar headpiece outputs, monopolar foot controlled output, bipolar handpiece output, and bipolar foot controlled output. The generator has a return electrode sensing feature allows the user to use either a split or solid return electrode site. The padsensing feature allows the user to use either a split or solid return electrode.

The device consists of a generator and power cord and is packaged with a User's Guide in a cardboard shipping box with protective foam inserts. The main device components are a front panel containing the power button, wattage selection buttons, LED numeric display, alarm and return electrode indicator lights, and connector ports for accessories, a back panel consisting of footswitch ports, volume controls, a power cord outlet and fuse, and internal components (printed circuit boards, speakers, cabling).

### Indications for Use

The ESU-1 Electrosurgical Generator [ESU-1] is used to deliver RF energy via an assortment of surgical devices to cut and coagulate different kinds of tissue.

### Comparison of Indications for Use to Predicate Device

The ESU-1 has the same indications for use as the Bovie IDS-310.

### Comparison of Technological Characteristics to Predicate Device

The ESU-1 has the following similarities to the Bovie IDS-310:

- Both devices have the same intended use/indications for use
- . Each device is identical in size, weight and construction.
- Each device uses high frequency RF current to deliver a desired clinical effect.
- Each device offers monopolar and bipolar output modes.
- Each device offers the same waveforms, output frequencies and maximum output . power for all monopolar modes.

{5}------------------------------------------------

- . Each device offers the same waveforms, output frequencies and maximum output power for Micro. Standard and Bovie Bipolar modes.
- Each device offers the AutoBipolar Feature.
- Each device offers the same Return Electrode Monitoring System.
- . Each device has the same chassis.
- Each device has the same interconnections, internal printed circuit boards and electrical components.
- . Each device has the same rated duty cycle.

The RF output for both generators is identical and both generators have identical modes with the exception that the ESU-1 has a "Cut T" mode, which includes a timing feature which automatically ceases RF activation after a user selectable period of time that can be altered between 0.1 and 3.0 seconds. The RF activation for Cut T mode is initially pre-set at 2 seconds. The Cut T mode replaces the Cut II function on the IDS-310. The RF output for both generators is identical.

### Performance testing

The software for the ESU-1 has been verified and validated based on its moderate level of concern. The ESU-1 complies with IEC60601-1 (third edition), IEC60601-2 (electromagnetic compatibility), and IEC60601-2-2 standard for the safety of electrosurgical equipment. Bench testing was performed to demonstrate that the generator met its design specifications. The testing consisted of Mechanical Verification Testing, Inspection Verification Testing, Electrical Verification Testing, Shipping Study, FPGA Validation for Main Board, FPGA Validation for Display Board and was conducted on the ESU-1 or devices representative of its design.

The results from these tests demonstrate that the technological characteristics and performance criteria of the ESU-1 are adequate for the intended use of the device and that the device can perform in a manner equivalent to devices currently on the market with the same intended use.

### Sterilization

The ESU-1 Electrosurgical Generator is a non-sterile device.

### Biocompatibility

The ESU-1 Electrosurgical Generator is not a patient contacting device.

{6}------------------------------------------------

### Conclusion

The ESU-1 met all the predetermined acceptance criteria of design verification and validation as specified by applicable standards, guidance, test protocols and/or customer inputs. The ESU-1 is substantially equivalent to legally marketed predicate devices.
