Description of the device that is the subject of this premarket notification

The Acculis Accu2i pMTA (Mk2) Applicator is a surgically invasive, sterile single patient use device that delivers microwave energy for the purpose of the coagulation of soft tissue and represents modifications of the predicate generally to add an intermediate length and reduce system output power range. Based on the modifications within this submission the generator software will also include respective changes to control the output and add multi lingual capabilities.

The Acculis MTA System as a whole includes the (1) Acculis Accu2i pMTA (Mk2) Applicator, (2) Sulis VMMA Generator with ver. 2.1.0 software, (3) Acculis Local Control Station and (4) optional MTA temperature probes. The Acculis Accu2i pMTA (Mk2) Applicator is a surgically invasive, sterile, single patient use device designed to deliver microwave energy for the purpose of the coagulation of soft tissue.

The Acculis Accu2i pMTA (Mk2) Applicator is available in three lengths 14cm (standard); 19cm (intermediate) and 29cm (long). These lengths permit the user to select the appropriate length to reach the target tissue area. The Acculis Accu2i pMTA (Mk2) Applicator incorporates a bespoke connector which interfaces with the SulisVaMTA Generator via the Acculis pMTA Local Control Station (LCS). The LCS, used to control coolant flow to the applicator, is connected to the generator using a microwave coaxial cable and an integrated 12V power supply and data cable.

The SulisVPMTA Generator is controlled via software version 2.1.0.

Explanation of how the device functions

The device releases microwave energy into the target tissue from a tuned microwave emitting array at the distal end of the applicator. The volume of coagulated tissue is regulated by the user by selecting the microwave power level and the duration for which the power will be applied. Guidance is given to the user by way of tables in the Instructions For Use that provide estimated coagulation zone dimensions for differing tissues at differing output powers and durations. Coagulation zones are monitored during treatment using appropriate intra-operative imaging techniques.

The microwave energy is delivered to the emitting array by a coaxial microwave transmission line. The transmission of energy through the cables causes cable heating which is dissipated by the liquid cooling system, controlled by the LCS. The applicator handle comprises a right angled microwave connector and coolant inflow and outflow chambers. These chambers direct the coolant inside the applicator and receive the exhaust flow from the applicator. The handle also

contains connections from the thermocouple that sits in the coolant flow and monitors coolant temperature.

The exhaust coolant is channeled from the applicator handle through an umbilical tube in which the flexible microwave supply coaxial cable sits. This cools the coaxial cable along its length.

The umbilical is terminated with a bespoke connector that integrates the coolant drive piston; coolant feed lines from/to the coolant reservoir and microwave and data connectors.

Scientific concepts that form the basis for the device 8.

The device coagulates tissue by the action of the microwave on the tissue as it is absorbed around the emitting array. The array is designed to create a near spherical microwave field in the tissue around the tip. The microwave energy is absorbed by the tissue through the coupling of the microwave to the water dipoles in the tissue. The rapid oscillation of the dipoles results in the transference of energy to the tissue within the microwave field in the form of heat. A zone of thermal conduction extends the coagulated zone beyond the actively microwave heated zone.

The microwave energy decays exponentially with distance from the applicator as the energy of the wave is absorbed. This distance is dictated by the microwave frequency used. This is a constant and is not user controlled. The user can control the rate of development and the size of the thermal coagulation zone using the power level and duration settings.

Significant physical and performance characteristics of the device

ு.

An efficient tissue heating mechanism is required to achieve the zones of tissue coagulation desired within the operative window available to clinicians. Microwave energy is known for its efficient heating of water dense materials. The chosen frequency of the device, 2.45GHz, allows sufficiently high power levels to be safely delivered within the target tissue. The efficient high pressure liquid cooling system, in which the transmission lines are carried, ensures that the transmission lines do not overheat. Thus the system delivers the desired rapid, yet safe, controlled and confined coagulation of the targeted tissue.

Microwave applicators operate by creating a microwave field in the tissue around the emitting array. No return electrodes or other materials must be applied to the patient for it to function.

The use of bespoke integrated connectors and simple recirculating coolant facilitates the correct setup of the device and minimizes any opportunity for incorrect device preparation.

The SulisVPMIA Generator software v. 2.1.0 is an upgrade to introduce multi language options for the onscreen text displays and additional fault symbology. The settings in the power control data table referenced by the software reflect revised upper and lower limits. No hardware changes have been made to the SulisVoMTA Generator from the predicate.

Performance Testing – Non-Clinical Testing 12.

The performance of the proposed device has been characterized using the same method used for the predicate device. Ex-vivo tissue types were used and coagulations conducted at various power and duration settings. The shape and size of the coagulation zones created were analyzed and compared to that of the predicate. Bench testing also included verification of coolant flow rates, surface temperature, interface compatibility, calorimetry, skin penetration and dimensional characteristics. These tests demonstrate that the performance of the candidate device is equivalent to that of the predicate.

The designed components were individually verified and validated in the course of establishing adherence to the applicable IEC 60601 standards.

13. Performance Testing - Clinical

Determination of substantial equivalence is made on the basis of the non-clinical testing referred to above. Clinical testing has not been conducted for either the proposed or predicate devices for the purposes of establishing equivalence.

14. Substantial Equivalence Discussion

The proposed device represents a modification of the applicator and generator software compared to the predicate device. All other components of the system remain the same. The modifications do not change the intended use, fundamental scientific technology or principle of operation. The energy, the control methodology, the system of cooling, the process of sterilization, the packaging and materials are all unchanged between the predicate and proposed devices. They Non-clinical performance testing are ergonomically and visually similar. demonstrates the proposed device delivers substantially equivalent performance to the predicate device.
