#### 4. Indications for Use
The Edison® System is indicated for the non-invasive destruction of liver tumors, including unresectable liver tumors, using a non-thermal, mechanical process of focused ultrasound.
#### 5. Device Description
The HistoSonics Edison System (the "System") provides users with a means to identify, target and destroy liver tumors entirely non-invasively using histotripsy, a non-ionizing, non
{5}------------------------------------------------
thermal, mechanical process of focused ultrasound. Histotripsy is created by delivering high amplitude, very short (microsecond), focused ultrasound pulses designed to induce controlled acoustic cavitation at a known focal location in the form of a "bubble cloud". The bubble cloud is a cluster of microbubbles that form, rapidly expand and collapse, imparting significant stress and strain on soft tissue, including liver tissue. After an adequate number of pulses (less than a few seconds at each bubble cloud location), liver tissue within the bubble cloud is mechanically destroyed, resulting in an acellular lysate with limited to no recognizable cellular structures. Acoustic cavitation (and bubble cloud formation) is only created when there is sufficient negative pressure to exceed the cavitation threshold, making it a threshold phenomenon.
The System is comprised of reusable medical equipment and disposable, single-patient use components intended for use in a professional healthcare environment. Reusable portions of the system include the Treatment Cart and a Support Arm and frame that is used to contain ultrasound medium (degassed water) that acoustically couples the system to the patient. Disposable aspects of the system include a clear, acoustically transparent and deformable membrane that holds the ultrasound medium as well as various non-active accessories used during patient set up. The Treatment Cart includes a Treatment Arm/Micropositioning System which is comprised of a six degree of freedom (6 DOF), dual encoded robotic arm. At the end of the arm is the Treatment Head which contains the histotripsy therapy transducer and a coaxially aligned diagnostic ultrasound probe. System software controls the Treatment Arm to direct the bubble cloud through the planned treatment volume.
The System is functionally integrated with a GE LOGIQ E10s ultrasound system (K211524), which is provided by HistoSonics with each Edison System.
# 6. Summary of Characteristics Compared to Predicate Devices
The Edison System under review is substantially equivalent to the Edison System cleared under DEN220087. The Edison System has the same technological characteristics as the predicates, that is, they operate in the same manner through the non-thermal, mechanical destruction of liver tumors by using non-invasive focused ultrasound.
Overall, the subject and primary predicate devices are all based on the same technological aspects as follows:
- . no change to the core histotripsy parameters or dose
- no increase in the level or amount of focused ultrasound energy delivered
- same thermal cooling table applied
{6}------------------------------------------------
The following primary technological differences exist between the subject and predicate devices:
- . Larger bubble cloud size of ~3x3x11mm (subject device) versus a ~3x3x6mm (predicate device) via the use of dynamic electronic micro-steering.
- . 3cm diameter sphere treated with the predicate device would take a minimum of 23 minutes while the subject device will take a minimum of approximately 13 minutes.
See table below for a detailed summary of the characteristics compared to the predicate device.
