# SUMMARY OF SAFETY AND EFFECTIVENESS INFORMATION CUSA EXCEL ULTRASONIC SURGICAL ASPIRATOR SYSTEM

## Product Description:

The CUSA EXcel Ultrasonic Surgical Aspirator System is an ultrasonically vibrating surgical device which, in combination with irrigation and aspiration, fragments, emulsifies and removes unwanted tissue. It allows the selective dissection of target tissues while preserving vessels, ducts and other delicate structures. The CUSA EXcel System consists of a console which provides control and power functions, a surgical handpiece which provides ultrasonic mechanical energy to the surgical site, a titanium handpiece tip and flexible irrigation flue, and a suction/irrigation system (manifold tubing and cooling water canister). The CUSA EXcel System accommodates most commercially available suction canisters, and specimen traps (optional). A two-pedal footswitch is provided with the console.

The CUSA EXcel System may be used with an external CUSA Electrosurgical Module (CEM), which will provide optional electrosurgical capability. The CEM module is a Force FX-8 Generator (FDA clearance was received for the Force FX Generator under K#944602). This provides the surgeon with the option of delivering cutting or coagulating current through the CUSA handpiece tip to the surgical site. The CEM function is controlled either with the Force FX-8 footswitch or by hand, using the CEM nosecone control button(s).

The main features of the CUSA EXcel Ultrasonic Surgical Aspirator System are as follows:

- Console is small and easy to move �
- Small, lightweight, ergonomic handpiece (CUSA EXcel 36kHz Handpiece) �
- Variety of tip diameters and lengths for specific surgical applications �
- � External CUSA Electrosurgical Module (CEM) provides optional electrosurgical capability and hemostasis
- � Protective, flexible irrigation flue to shield the surgical tip and prevent trauma to surrounding tissue
- � Simple to set-up and use
- � CUSA EXcel Console is compatible with the currently marketed Valleylab CUSA PFT Ultrasonic 23kHz Straight Handpiece (C2500)
- � Ability to change tips in a sterile surgical environment, such as a hospital operating room
- � Preaspiration holes in the surgical tip minimize clogging and keep tip clear of debris
- � Two-mode suction capability for open and laparoscopic procedures

{1}------------------------------------------------

- Fast Flush mode flushes the operative site with irrigation fluid �
- Coaxial fluid delivery to maintain cooling and irrigation at the surgical tip, � and to efficiently remove debris for added visualization
- Includes TISSUE Select feature for control of fragmentation rate, and � enhanced tactile feedback for added selectivity

#### II. Intended Use:

Validation and verification of the CUSA EXcel System will be accomplished through a combination of analysis and testing. This process will include a Risk Analysis and an electro/mechanical performance test on prototype units. The safe performance and proper function of the hardware and external controls of the CUSA EXcel Console will be tested (Note: the EXcel Console contains no microprocessor and no memory). The CUSA EXcel Handpiece and accessories will also be tested, both alone and in conjunction with the Console. The following is a summary of the testing to date, including test criteria, performed on the CUSA EXcel Console and the CUSA EXcel Handpiece. Testing has verified the safe performance and proper function of the product

The biological safety of the CUSA EXcel Ultrasonic Surgical Aspirator System devices has been assured through the selection of materials which demonstrate appropriate levels of biocompatibility. Many of the materials used in the CUSA EXcel System are the same as currently used in Valleylab CUSA System 200 devices, which are legally marketed device(s); refer to Attachment 3 for a complete listing and 510(k) references. Those materials which are unique to the CUSA EXcel System are currently undergoing testing in accordance with ISO Standard 10993-1, Biological Evaluation of Medical Devices, Part 1 - Guidance on Selection of Tests, Device Category "External Communicating Device, Blood Path Indirect, contact duration A".

- Summary of Substantial Equivalence: IV.
The CUSA EXcel Ultrasonic Surgical Aspirator System (Console, Handpiece, and Accessories) is substantially equivalent in function and intended use to the following legally marketed devices:

- Valleylab CUSA System 200 (510(k)'s K#921251, K#931902, K#934628) ◆ This console system operates at a frequency of 23kHz. The above submissions included 23kHz handpieces (CUSA PFT Ultrasonic Handpiece) and system accessories.
- . Valleylab CUSA System 200H with 37kHz Handpiece (510(k) K#884413). This smaller handpiece operates at a higher frequency (37kHz) for applications which demand greater precision and user visibility.

A comparison chart of product features is located in Attachment 6. Included in Attachment 7 is a copy of the advertising literature for the CUSA System 200 Console and CUSA PFT Ultrasonic Handpiece.

The surgical indications outlined for the CUSA EXcel Ultrasonic Surgical Aspirator System (refer to section G. Intended Use) are identical to those indications which have been cleared by FDA in previous 510(k) submissions for the CUSA System 200 Ultrasonic Surgical Aspirators. Refer Attachment 8 for a
