Device Story

Tracheostomy tubes provide artificial airway for adults requiring respiratory support or airway management. Device inserted through tracheotomy incision; secured via neckstrap attached to swivel neck flange. Features include extended proximal/distal lengths for anatomical variation, cuffed or uncuffed options, and flexible corrugated inner cannula (XIC) with 15mm push-lock connector. Used in clinical settings for spontaneous breathing or connection to anesthesia/ventilation equipment. Provides secure airway access; benefits include improved fit for unique patient anatomy and compatibility with standard ventilation equipment.

Clinical Evidence

Technological Characteristics

Tracheostomy tube with swivel neck flange. Materials: inflation cuffs utilize same material as Mallinckrodt Broncho-Cath. Features: extended proximal/distal lengths, flexible corrugated inner cannula (XIC), 15mm push-lock connector. Connectivity: mechanical interface for ventilation/anesthesia equipment. Sterilization: not specified.

Indications for Use

Indicated for adult patients requiring tracheal access for airway management, including spontaneous breathing or mechanical ventilation.

Regulatory Classification

Identification

A tracheostomy tube and tube cuff is a device intended to be placed into a surgical opening of the trachea to facilitate ventilation to the lungs. The cuff may be a separate or integral part of the tracheostomy tube and is, when inflated, intended to establish a seal between the tracheal wall and the tracheostomy tube. The cuff is used to prevent the patient's aspiration of substances, such as blood or vomit, or to provide a means for positive-pressure ventilation of the patient. This device is made of either stainless steel or plastic.

## Device Description:

These devices are used to provide an artificial airway, in order to assist in the treatment of a variety of respiratory diseases and airway management in adults. After insertion in place through a tracheotomy incision in the patient’s neck and trachea, the devices are then secured in place with a tiestrap around the patient’s neck, which is attached to the tracheostomy tube’s swivel neck plate/flange. Once in place, these devices provide a secure artificial airway for spontaneous breathing or direct hook-up to ventilation or anesthesia equipment.

## Intended Use:

The intended use of the modified devices will continue to be provision of tracheal access for airway management in adults.

## Comparison of Technological Characteristics of Subject Versus Predicate Devices:

### Similarities:

- The new devices will be available in extended lengths, up to 105mm (compared to the standard Shiley DCT). These lengths are comparable to the predicate Shiley Specialized Tracheostomy Tubes.
- The new devices will be available in *cuffed* and *uncuffed* versions.
- Like predicate Shiley tracheostomy tubes, each Extended Length tracheostomy tube will be packaged with an obturator and neckstrap.
- Soft Swivel Neck Flange: This feature was found to be substantially equivalent to the current stiff swivel neck flange design in 510(k) #K962173 (cleared 10/4/96).
- The new devices’ inflation cuffs will utilize the same material used in the Mallinckrodt Broncho-Cath Endobronchial Tube.

### Differences:

- Non-arcuate tracheostomy tube shapes (compared to the arcuate standard Shiley DCT): The Extended Length Tracheostomy Tubes devices will vary in tube length along the *proximal* end of the tube (*before* the curvature of the tube) or along the *distal* end of the tube (*after* the curvature of the

tube), in order to accommodate unique anatomical needs. Comparable non-arcuate trach tube shapes are currently available in the predicate Shiley Specialized Trach Tubes and the Shiley Sleep Apnea Trach Tubes.

- Flexible extended length, disposable Inner Cannula. In order to accommodate the extended proximal and distal section lengths of these new devices, it was necessary to develop a more *flexible* Disposable Inner Cannula. The new *flexible* Extended Length Inner Cannula (“XIC”) has a “corrugated” appearance which allows the inner cannula increased lateral flexibility, while maintaining appropriate column strength. The predicate SIMS Profile device also features a flexible disposable Inner Cannula.
- The new XIC Disposable Inner Cannula terminates in an integral 15mm *push*-lock Connector (current 15mm connectors on standard Disposable Inner Cannulae (DIC) feature an integral *snap*-lock connector design).
- More flexible Outer Cannula body than the standard Shiley DCT (comparable to the predicate Mallinckrodt Hi-Lo Tracheal Tubes).

## Performance/Clinical Data:

### A. In-vitro performance data:

| Test | Predicate Device Test Results | Modified Device Test Results | CEN Standard Requirements |
| --- | --- | --- | --- |
| Tie Strap Hole Strength: | 26.7 lbs force (SCT) | 45.8 lbs force | No requirement for this test parameter |
| Outer cannula body to Trach Head Base Bond Strength | 143.0 lbs force (SCT) | 55.0 lbs force | No requirement for this test parameter |
| Trach Head Base-to-Head Cap Bond | N/A | 90.5 lbs force | No requirement for this test parameter |
| Cuff Burst Strength | 8.3 lbs force (SCT) | 6.6 lbs force | No requirement for this test parameter |
| 15mm Connector Disconnect Force | 19.1 lbs force (SCT) | 19.4 lbs force | No requirement for this test parameter |
| Neck Plate to Trach Tube Body Attachment Strength: | 42.1 lbs force (DCT) | 27.7 lbs force | minimum 11.3 lbs force |

### B. Clinical Data: Clinical data was not necessary, since device performance can be adequately assessed by in-vitro testing.

In conclusion, the similarities to the predicate devices, in conjunction with the physical integrity test results, demonstrate that the proposed modifications to these devices do not impact safety or effectiveness.

## Summary:

The data presented demonstrate that the proposed modifications (extended proximal and distal lengths, flexible spiral inner cannula design) to Shiley Tracheostomy Tubes does not impact device performance characteristics and, thus, does not raise new safety and efficacy questions. This information supports the conclusion that the modified Shiley Tracheostomy Tubes and accessories are substantially equivalent in intended use, operation, and characteristics, as compared to existing legally marketed devices.
