Indications for Use

The Dyonics® InteliJET™ Inflow/Outflow Cannula is indicated for use with the InteliJET Fluid Management System during arthroscopic surgical procedures of the knee, shoulder and small joints to regulate flow of irrigation fluids through the joint to maintain intra-articular pressure for uniform distention and clear visualization of the surgical site.

Device Story

Dyonics InteliJET Inflow/Outflow Cannula establishes surgical portal during arthroscopy; functions with InteliJET Fluid Management System. Device utilizes pressure-sensing feedback mechanism to regulate irrigation fluid flow; maintains intra-articular pressure for uniform joint distention and clear visualization. Used in OR by surgeons; provides real-time fluid management to optimize surgical site visibility. Benefits include improved visualization and consistent joint distention during knee, shoulder, and small joint procedures.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and functional comparison to predicate devices.

Technological Characteristics

Cannula for arthroscopic fluid management; incorporates pressure-sensing feedback mechanism for integration with InteliJET Fluid Management System. Materials and design equivalent to existing reusable cannulas and 3M pressure-sensing sheath systems.

Indications for Use

Indicated for use during arthroscopic surgical procedures of the knee, shoulder, and small joints to regulate irrigation fluid flow and maintain intra-articular pressure for visualization.

Regulatory Classification

Identification

An arthroscope is an electrically powered endoscope intended to make visible the interior of a joint. The arthroscope and accessories also is intended to perform surgery within a joint.

Predicate Devices

• Dyonics InteliJET Reusable Cannulas
• 3M™ Inflow/Outflow Pressure Sensing Scope Sheath System

# Smith = Nephew

The Dyonics InteliJET Inflow/Outflow Cannula is substantially equivalent to the 3M™ Inflow/Outflow Pressure Sensing Scope Sheath System in design, materials, principal of operation and intended use. Both cannulas work with their respective control units to maintain and optimize joint distention via a pressure sensing feedback mechanism.

Furthermore, the InteliJET Inflow/Outflow Cannula is substantially equivalent in materials, function and intended use to currently offered InteliJET Reusable Cannulas.

#### Predicate Device:

The predicate devices for this submission are the currently marketed Dyonics InteliJET Reusable Cannulas and the 3M™ Inflow/Outflow Pressure Sensing Scope Sheath System.

#### Summary of Device Function:

The Dyonics InteliJET Inflow/Outflow Cannula is used to establish a portal to the surgical site during arthroscopic surgical procedures. The Dyonics InteliJET Inflow/Outflow Cannula is designed to work in conjunction with the InteliJET Fluid Management System to maintain intraarticular pressure for uniform distention and clear visualization of the surgical site.

### Intended Use of Device:

The Dyonics InteliJET Inflow/Outflow Cannula is indicated for use with the InteliJET Fluid Management System during arthroscopic surgical procedures of the knee, shoulder and small ioints to regulate flow of irrigation fluids through the joint to maintain intra-articular pressure for uniform distention and clear visualization of the surgical site.

## Comparison of Technological Characteristics of Predicate Device:

The basic technologies, design and function of the Dyonics InteliJET Inflow/Outflow Cannula is substantially equivalent to technologies, design and function found in the current InteliJET Reusable Cannulas and the 3M Inflow/Outflow Pressure Sensing Scope Sheath System. The minor differences between these devices raise no new issues of safety and effectiveness.
