Intended Use

The Helix Hydro-Jet is intended for the cutting and dissection of soft tissue such as the liver, kidney, etc, within the abdomen, including Total Mesorectal Excision (TME), in open as well as laparoscopic surgery.

Device Story

Helix Hydro-Jet is a hydraulic pressure delivery system using physiological saline to cut and dissect soft tissue. System components include a unit, suction container, power cord, foot pedal, fluid cartridge, suction bag, and various applicators. Operates by delivering a pressurized saline jet (1 to 2,175 psi) through a cannula (120 µm jet diameter). Used in OR by surgeons for open or laparoscopic abdominal procedures. Added applicators feature handles, flexible tips, hooks, and increased lengths (up to 336 mm) to improve access in hard-to-reach areas. Surgeon controls jet delivery via foot pedal. Provides tissue selectivity and improved visibility during dissection compared to traditional methods. Benefits include precise tissue cutting and dissection in proximity to critical structures.

Clinical Evidence

No clinical trials conducted. Evidence consists of an exhaustive literature search and clinical evaluations supporting the safety and efficacy of the water jet system for TME and laparoscopic abdominal surgery. Documentation indicates the device provides greater visibility and tissue selectivity compared to other approved equipment.

Technological Characteristics

Hydraulic pressure delivery system. Pressurized sterile saline (1-2,175 psi) used for cutting/dissection. Applicators: 1.6-6 mm outer diameter, 60-336 mm length, various tip geometries (straight, curved, flexible, hooked). Materials: No change from K012464. Sterilization: Fluid cartridge (Gamma), Applicators (Ethylene Oxide). System includes reusable unit/pedal and disposable fluid/suction components.

Indications for Use

Indicated for patients requiring open or laparoscopic surgery in and around the abdomen for the cutting and dissection of soft tissue, including Total Mesorectal Excision (TME).

Regulatory Classification

Identification

A jet lavage is a device used to clean a wound by a pulsatile jet of sterile fluid. The device consists of the pulsing head, tubing to connect to a container of sterile fluid, and a means of propelling the fluid through the tubing, such as an electric roller pump.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 880.9.

Common Name: Water Jet Dissector

Helix Hydro-Jet™ Trade/Proprietary Name:

Classification Name: Jet Lavage (21CFR880.5475)

FQH Product Code:

Legally Marketed Device: Helix Hydro-Jet

Note: This 510(k) is being submitted to modestly expand the intended use for the Helix Hydro-Jet. There are three additional applicators in this 510(k) that would support the added indications. They were also included in the previous 510(k) [K012464] but were removed when the intended use was limited.

### Device Description:

The Helix Hydro-Jet is a hydraulic pressure delivery system that uses physiological saline to cut and dissect soft tissue. A very detail description of the system can be found in the previous 510(k), K012464, Device Description 1-1.

Note: A summary of design control activities, risk analysis, verifications/validations, and biocompatibility can also be found respectively in Sections 4-1, 5-1, 6-1, 9-1, and 8-1 of the previous 510(k). Also, certifications and the declaration of conformity are in the former 510(k) Appendices A and B respectively.

## Intended Use *:

The Helix Hydro-Jet is intended for the cutting and dissection of soft tissue such as the liver, kidney, etc, within the abdomen, including Total Mesorectal Excision (TME), in open as well as laparoscopic surgery.

*Modified 10/18/02 per request by FDA.

# 510K SUMMARY

Similarities and Differences of the Modified Device to the Current Device (Predicate Comparison/Substantial Equivalence):

The modified device is the same as the predicate except for a slight expansion of the intended use and the addition of supporting applicators.

The difference to the indication is:

- 1. Cutting and dissection of soft tissue in the abdomen including Total Mesorectal Excision (TME)* {Change from just using the device in the Abdomen} and
- 2. Laparoscopic use in treating the target tissue (Change from just using the device in open surgerv).

The modest change to the intended use is supported by scientific documentation provided in this Section as apart of Clinical Evaluations (See 111-9).

Collectively the added applicators are different in that:

- 1. One of the applicators has a handle and a flexible tip,
- 2. The maximum cannula length changed from 300 to 336 mm, and
- 3. One of the applicators has a hook.

The additional features in having a handle, flexible tip, hook, and/or being slightly longer provide surgeon's applicators that would especially be useful in hard to reach areas as well as for laparoscopic use in or near the abdomen. The applicators have been verified/validated in design control. Risk analysis also has been performed with regards to the features.

## Conclusion:

All available/known studies involving the Helix Hydro-Jet and like water jet equipment in conjunction with the expanded intended use have been provided in this submission (Note: An exhaustive literature search was performed.). The clinical documentation provided demonstrates that the Helix Hydro-Jet may be used safely and effectively to cut/dissect soft tissue that is in close proximity of the abdomen [Note: Shown by use in Total Mesorectal Excision (TME)]. The evaluations also show that system can be used in laparoscopic procedures for the target tissues with regards to safety and efficacy. Finally, the modified structural and dimensional features of the added applicators do not adversely affect the safety or effectiveness of the Helix Hydro-Jet.

The use of the Helix Hydro-Jet in TME was found to be better in comparison to other approved equipment. Greater visibility and tissue selectivity with the water jet system
