Intended Use

The Focal One® device is indicated for transrectal high intensity focused ultrasound (HIFU) ablation of prostate tissue.

Device Story

Focal One® is a high-intensity focused ultrasound (HIFU) system for prostate tissue ablation. It utilizes an endorectal dynamic focusing probe to deliver ultrasound energy through the rectal wall, focusing on targeted prostate tissue to induce thermal ablation. The system includes a control module, computer, cooling unit, and disposable FocalPak kit. A coupling liquid (Ablasonic®) circulates through a balloon to protect the rectal wall. The device is operated by a physician in a clinical setting. The physician uses integrated imaging (ultrasound and DICOM fusion) to localize the prostate and plan treatment. The system uses pre-set algorithms to guide the stepwise destruction of targeted tissue. The device provides visual feedback via dual touch-screens, mouse, and keyboard. The procedure is minimally invasive and performed on an outpatient basis under anesthesia. The device benefits patients by providing a targeted, non-surgical ablation option for prostate tissue.

Predicate Device(s): EDAP Technomed, Inc.'s Focal One® (K172721)

## Intended Use:

The Focal One® device is indicated for transrectal high intensity focused ultrasound (HIFU) ablation of prostate tissue.

## Device Description:

The Focal One® is an evolution from the previous generation of Focal One® by EDAP as cleared in K172721. The Focal One® consists of the Focal One® module with a software control system, an endorectal dynamic focusing probe, a leg support, and a disposable set (FocalPak) including miscellaneous single use disposables and a coupling liquid pouch.

The Focal One® module consists of a motorized and manual endorectal dynamic focusing probe positioning unit, a RF amplifier to power the transducer, a computer to control device operation, a cooling system to cool Ablasonic (coupling liquid) and built-in safety features. It also allows the user to control the treatment while providing different user interfaces: two dual touch-screens, mouse, keyboard and printer. The Focal One® energy is delivered via an endorectal dynamic focusing probe, which includes an imaging system. The high-energy ultrasound waves propagate through the rectal wall and are focused on a portion of the prostate, generating heat and causing the ablation of tissue within the focal area. The process is then repeated in a stepwise fashion to destroy the targeted tissues within the prostate. The endorectal dynamic focusing probe is attached to a support, enabling movements in the longitudinal, transverse, vertical and angular directions, and in rotation. A coupling

liquid pouch (Ablasonic®) included in the FocalPak disposable kit, attached to a stand, maintained at a controlled temperature flows continuously (via a peristaltic pump) into the balloon to preserve the rectal wall from heating associated with the treatment. The module is mounted on four multidirectional wheels allowing an easy positioning of the device in the treatment room.

## Substantial Equivalence

The subject Focal One® device is an updated version of the previously cleared Focal One® (K172721) and is substantially equivalent to the Focal One® System cleared in K172721 ("predicate device"). The subject Focal One has the identical indications for use and principles of operation, and similar technological characteristics, as the previously cleared predicate. Minor differences in the technological characteristics between the subject device and the predicate do not raise different questions of safety or efficacy.

The ultrasound treatment by the therapeutic transducer remains unchanged compared to the cleared version. The main difference is the inclusion of a new imaging ultrasound to replace the imaging ultrasound in the cleared device. Notably, the modification to the imaging scanner has no impact on the overall device specification. Nor does it affect the user interface or the safety features of the device.

Other minor updates have been made, e.g., to replace obsolete components without altering specifications. None of the changes affect the treatment parameters or energy specifications.
