Intended Use

The Sonowand Invite System is intended for use as a tool to aid intraoperative ultrasound imaging and image guided surgery during neurosurgery. It is also intended for use as a standard neuronavigation system and as a stand-alone ultrasound scanner. The intended use of a localizer is to enable navigation by showing the position of surgical instruments or pointers relative to MR, CT or Ultrasound images. The General purpose localizers with adapters are intended to be used to attach surgical tools manufactured by other vendors. SonoWand Invite System will display position and orientation of the tools in the medical images on the screen.

Device Story

SonoWand Invite is a neuronavigation system integrating an ultrasound scanner; used in neurosurgery. System tracks position/orientation of surgical tools or pointers relative to MR, CT, or ultrasound images. New accessories (general purpose localizers and adapters) allow attachment of third-party surgical tools to the system. Surgeon operates system via graphical touch screen or footswitch. Output displayed on screen; assists surgeon in visualizing tool location relative to patient anatomy during procedures. Benefits include improved navigation accuracy and intraoperative imaging capabilities.

Clinical Evidence

Bench testing only. No clinical data. Testing included cleaning and sterilization validation, system integration testing, and verification of fit, calibration, and accuracy for the new localizers and adapters.

Technological Characteristics

Materials: 316L Stainless steel, 6082 Aluminium with DLC coating, and Radel PPSU (PEEK). System integrates ultrasound scanner with neuronavigation rack. Connectivity: Touch screen and footswitch interface. Sterilization: Compatible with standard surgical cleaning/sterilization protocols. Biocompatibility: Compliant with USP and ISO 10993-1.

Indications for Use

Indicated for neurosurgery patients requiring intraoperative ultrasound imaging or image-guided surgery. Used by surgeons to track surgical instruments or pointers relative to preoperative MR, CT, or intraoperative ultrasound images.

Regulatory Classification

Identification

## Equivalent Device Identification:

The purpose of this submission is to add additional accessories to the SonoWand Invite System. The additional accessories are general purpose localizers with adapters. These accessories are equivalent in function and intended use to the Navigator tool which was cleared in the original 510(k), K083597.

### Device Description:

The 510(k) cleared SonoWand Invite System is a neuronavigation system with intraoperative imaging capabilities. An ultrasound scanner is physically integrated with a neuronavigation system in a single rack of equipment.

SonoWand Invite can be used as a conventional neuronavigation system based on preoperative MR or CT-images, or as a stand-alone ultrasound scanner for real-time 2D imaging or as a combined system where 3D ultrasound data can be transferred to the navigation system for direct navigation.

SonoWand Invite has basically two functionalities. It supports the surgeon by showing the position of tools or pointers relative to MR, CT or Ultrasound images. It also makes it possible for the surgeon to acquire ultrasound images during operation, which can be compared with other images (such as MR or CT) and can be used for supporting the surgeon by showing the position of tools and pointers. The control is primarily by a graphical touch screen. The secondary control is by a footswitch.

The new accessories, General purpose localizers with adapters, shall be used to attach surgical tools manufactured by other vendors. SonoWand Invite will then display position and orientation of the tools in the medical images on the screen in the same way as the previous 510(k) cleared Navigator tool.

The localizers with adapters are designed to fit surgical tools normally used in the operating room.

There are no changes to the Intended use, function or technological aspects including software of the SonoWand Invite. The additional accessories are being added to increase usability of the SonoWand Invite system.
