Intended Use

The OmniSonics Ultrasonic Probes are used in conjunction with the OmniSonics Ultrasonic Surgical System to utilize ultrasonic energy for the removal of tissue. The intended use of the device is the breakup and removal of soft tissues in Neurosurgery, GI and affiliated organ surgery, Urology, General surgery, Plastic and Reconstructive surgery, Orthopedic, GYN, Thoracic. The OmniSonics Ultrasonic Probes are designed to be introduced through natural body cavities or surgical incisions through introducers, needles or trocars, catheters, sheaths or other devices with lumens having an inside diameter larger than the outside diameter of the probe.

Device Story

Ultrasonic aspiration device; consists of titanium probes used with OmniSonics Ultrasonic Surgical System generator. Generator converts electrical signal to ultrasonic motion in handle; transferred to probe shaft. Probe contact with tissue induces localized cavitation; microbubble formation and collapse creates focused shock waves; destroys and removes soft tissue. Used in surgical settings (neurosurgery, GI, urology, general, plastic, orthopedic, GYN, thoracic) by surgeons. Introduced via natural orifices or incisions using trocars/catheters. Provides precise tissue removal limited to probe contact area; benefits patient through controlled, localized tissue destruction.

Clinical Evidence

Bench testing only. Device tested for compliance with IEC 60601. Materials confirmed biocompatible. Sterilization validated to SAL 10^-6 per AAMI guidelines for ETO.

Technological Characteristics

Titanium construction; ultrasonic aspiration principle; energy source: external ultrasonic generator; dimensions: 1-10mm exterior diameter, 0.5-8mm interior diameter, 10-30mm length; sterilization: ETO.

Indications for Use

Indicated for the breakup and removal of soft tissues in neurosurgery, GI, urology, general surgery, plastic/reconstructive surgery, orthopedic, GYN, and thoracic surgery. Designed for introduction via natural body cavities or surgical incisions using introducers, needles, trocars, or catheters.

Proprietary Name: OmniSonics Ultrasonic Probes Common/Usual Name: Ultrasonic Aspiration Device Classification Name: Ultrasonic Aspiration Device

- Identification of Predicate or Legally Marketed Device 3.
The OmniSonics Ultrasonic probes are substantially equivalent to the following predicate devices: Sonokinetics SONOTOME System (K99XXXX) and Valleylabs Inc. CUSA® 200 System (K853143, K864983, K884412, K884413, K894600, K910696) and CUSA EXCEL System (K981262).

- 4. Device Description
### Principle of Operation

The OmniSonics Ultrasonic probes work in conjunction with the OmniSonics Ultrasonic Generator. The generator creates a specific electrical signal that is directed into the OmniSoncs ultrasonic handle. The signal is converted into an ultrasonic motion within the handle and this motion is transferred to the ultrasonic probe.

> The ultrasonic energy in contact with the probe causes a specifically defined motion to occur on the probe shaft. The motion of the probe in contact with the tissue causes a localized cavitation, and immediate destruction of the tissue in contact with the probe. Cavitation is caused by the motion of the probe within water and in contact with tissue.

The motion of the probe causes the formation of microbubbles to be formed. The upstoke of the probe causes the formation of the bubble behind the probe, the downstroke causes the collapse of the bubble and a small localized shock wave. This focused wave formed at the tip of the probe causes a localized and focused shock wave to be formed which impinges upon the tissue and breaks off the most least tightly bound tissue layer. The action is limited to a specific contact area of the probe upon the tissue, and does not travel beyond these contact points.

### Device Configuration and Materials

The OmniSonics Ultrasonic Probes are constructed of titanium and are all specifically designed for use and operation with the OmniSonics Ultrasonic Surgical System.

The specifications of the proposed OmniSonics Ultrasonic Probes are the following:

| Diameter Exterior | 1 mm - 10 mm |
|-------------------|---------------|
| Diameter Interior | .5 mm - 8 mm |
| Length | 10 mm - 30 mm |

#### న్. Intended Use

The OmniSonics Ultrasonic Probes are used in conjunction with the OmniSonics Ultrasonic Surgical System to utilize ultrasonic energy for the removal of tissue. The intended use of the device is the breakup and removal of soft tissues in Neurosurgery, GI and affiliated organ surgery, Urology, General surgery, Plastic and Reconstructive surgery, Orthopedic, GYN, Thoracic.

#### Comparison of Technological Characteristics 6.

The OmniSonics Ultrasonic probes are substantially equivalent to the following predicate devices: Sonokinetics SONOTOME System (K990572) and Valleylabs Inc. CUSA® 200 System (K853143, K864983, K884412, K884413, K894600, K910696) and CUSA EXCEL System (K981262).

Ultrasonic aspiration of tissue through hollow titanium needles has been a part of the U.S. medical landscape since the 1960s. As such, the predicate devices to which the OmniSonics Ultrasonic Probes is substantially equivalent in intended use are based on a well developed technology.

The intended use of the OmniSonics Ultrasonic Probes are the same as that of other manufactures of ultrasonic probes in that they are intended for the breakup and removal of soft tissues in Neurosurgery, GI and affiliated organ surgery, Urology, General surgery, Plastic and Reconstructive surgery, Orthopedic, GYN, Thoracic.

The OmniSonics Ultrasonic Probes have similar technological characteristics to and similar applications as the predicates Sonokinetics SONOTOME System and CUSA® 200 System, in that they are all metal alloy instruments that are attached to an ultrasonic handle providing the ultrasonic energy and motion to the probe to cause a destruction of contacted tissues. All of the devices on the market offer various configurations, lengths, diameters, use an external ultrasonic handpiece as the source of energy and are made of either titanium, stainless steel. The OmniSonics tip does not raise new questions of safety and effectiveness.

- 7 Performance Testing
The OmniSonics Ultrasonic Probes are tested in compliance with IEC 60601.

The materials used in the manufacture of the OmniSonics Ultrasonic Probes are biocompatable.

The OmniSonics Ultrasonic Probes are sterilized to an SAL of 10° in accordance with AAMI guidelines for ETO sterilization.
