## Device Description Summary
21 CFR 807.92(a)(4)

The reprocessed HARMONIC 700 with Advanced Hemostasis are designed for soft tissue incisions requiring bleeding control and minimal thermal injury. These instruments serve as an adjunct to or substitute for electrosurgery, lasers, and steel scalpels in various procedures, including general, pediatric, gynecologic, urologic, and thoracic surgeries, as well as in the sealing and transection of lymphatic vessels. They enable the coagulation of vessels up to 7 mm in diameter using the Advanced Hemostasis hand control button.

The instruments are available in three (3) shaft lengths: 23cm, 36cm, and 45cm lengths (HAR723, HAR736, and HAR745 respectively). Each shaft length has a diameter of 5 mm. The following features are essential to the control and performance of the device:

- An actuating trigger that closes and releases the clamp arm, securing tissue against the scalpel rod.
- MIN/MAX control buttons that adjust energy levels between minimum and maximum modes on the generator, enabling vessel sealing up to 5 mm.
- An Advanced Hemostasis button that allows the clinician to activate an additional energy mode, enabling vessel sealing up to 7 mm.
- A rotation knob to rotate the shaft 360° unless energy is being delivered.
- A torque wrench, a sterile, single-use component, used to apply the correct amount of torque when attaching the Hand Piece to the device.

The instruments connect to a generator and hand piece, which are essential for the device's functionality but are outside the scope of this submission.

{6}

K250898

The hand piece is a reusable component that attaches to the device and plugs into the generator, allowing the device to interface with the generator. This component contains the transducer, which converts electrical power to ultrasonic mechanical energy.

The generator is a reusable component that generates the electrical signal. Colored light indicators on the front panel of the generator visually communicate device status information to the user.
