Intended Use

The device is a helium gas electrosurgical cutting and coagulator for use in all soft tissue surgery-laparoscopic ,endoscopic and open .

Device Story

Helium gas electrosurgical system consisting of power generator control unit and application probe. Device generates ionized helium gas plasma flame. In corona mode, flame has high electron temperature but low molecular temperature (~20C). Upon proximity (within 3mm) to earthed tissue, flame transitions to arc discharge (~800C). Inert helium flow minimizes oxidation. LTC probe features retractable 4mm PTFE sheath exposing brass insert for mechanical/thermal cutting while cauterizing small vessels. Used in OR/clinic by surgeons for soft tissue surgery. Visual feedback guides depth/width of effect. Benefits include controlled necrosis depth and lower power requirements compared to argon beam coagulators.

Clinical Evidence

Bench testing only. In vitro comparison of Helica thermal coagulator (HTC) vs. argon beam coagulator (ABC) performed. Results indicate HTC provides better control of necrosis depth than ABC, with similar clinical outcomes at lower power levels, supporting a favorable safety profile.

Technological Characteristics

Helium gas electrosurgical coagulator. Components: power generator, helium supply, PTFE application probe with brass insert. Energy: alternating current, fixed frequency (kHz range), 2-30W power range. Principle: ionized helium gas plasma (corona to arc discharge).

Indications for Use

Indicated for use in all soft tissue surgery, including laparoscopic, endoscopic, and open procedures, for cutting and coagulation.

Regulatory Classification

Identification

## Description of Device:

"The device is a helium gas electrosurgical coagulator for use in all soft tissue surgery-laparoscopic, endoscopic and open"

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

K032969 (pg 2 of 3)

It consists of two parts:

- A power generator control unit with a Helium gas supply. .
- . An application probe.

An ionised gas plasma flame is generated in a controlled Helium gas flow at the end of a 4mm PTFE application tube (the probe). This produces a corona-type flame issuing from the open end of the probe with a high electron temperature but low molecular temperature of about 20C. When the probe is brought close (within 3 mm) to a surface connected to earth - such as human tissue - the corona-type flame changes to an arc discharge flame with a temperature of approx. 800C. The inert Helium gas flow in which the discharge takes place protects the area of discharge and minimises oxidation.

This plasma flame can be used to stop blood flow from damaged tissue by cauterisation.

The electrical generator provides an alternating current at a fixed frequency in the kilo hertz range with a power supply range of between 2 and 30W.

Referring to the application probe, which the model is the LT, the L is for Laparoscopic and the T is the length.

The new probe is the LTC. This is a cutting probe where the 4mm PTFE tube retracts, exposing the point which is approximately 8-10mm long. This probe works by using the Corona flame passing between the point and the tissue at the nearest point which could be on the side of the probe. The point area which is hot then cuts through the tissue and cauterises small blood vessels as it passes through.

# Statement of Intended Use:

"The device is a helium gas electrosurgical cutting and coagulator for use in all soft tissue surgery-laparoscopic ,endoscopic and open ".

#### Description of Modification:

The basic design of the Helica probe remains the same. However the handle of the LTC probe has been modified to allow the PTFE sheath to be retracted; this exposes the brass insert, which can then be used as a cutting instrument.

# Summary of Non Clinical Tests:

In vitro comparison of the Helica thermal coagulator (HTC) and the argon beam coagulator (ABC); Dr. John Webb, Ph.D:

{2}------------------------------------------------

K032964 (pg 3 of 3)

The helium unit does have a much better control of the depth of necrosis than that of the ABC, but slightly less control over the width, perhaps due to the significantly greater power applied by the ABC to get the same effect. However, the judgement of effect of each of these unite while in use during surgery is visual and it will be easy to judge the spread of the effect and not easy to judge the depth.

It can therefore be concluded that the use of the HTC should be easier than the AB, even given similar results, and the HTC should be considered "safer" with its much lower power at point of application.

# Substantial Equivalence:

The has the following similarities to those which previously received 510(k) clearance:

- have the same indicated use, .
- . use the same operating principle,
- incorporate the same design, .
- incorporate the same materials, .
- have the same shelf life, .
- and are packaged using the same materials and processes. .

In summary, described in this submission is substantially equivalent to the predicate device
