Atraumatic cannula for vocal cord paralysis and glottic incompetence; Ø2.0mm x 133mm

Delicate Precision for Laryngeal Augmentation with Safe Fat Harvesting

The Atraumatic Cannula for Vocal Cord Injection is purpose-built for the precise and gentle medialization of the vocal folds in patients with unilateral vocal cord paralysis or glottic insufficiency. Whether used with autologous fat or synthetic fillers, this cannula supports minimally invasive augmentation techniques via transoral, percutaneous, or endoscopic routes.

Atraumatic in both design and function, the cannula features a slender, smooth shaft and rounded distal tip, ensuring safe navigation through delicate laryngeal structures while allowing accurate placement into the paraglottic space.

Additionally, when used for autologous fat injection, the cannula plays a dual role in fat harvesting and delivery.
Careful harvesting is crucial to ensure successful and lasting vocal fold augmentation. In this design, the shape, spacing, and finish of the suction holes are optimized to protect the viability of adipose cells. The cannula's inner diameter is engineered to accommodate harvested fat without compression, allowing gentle aspiration under low negative pressure. This preserves cell structure, making it ideal for long-term integration in the vocal fold.

Features:

• Atraumatic rounded tip for safe transoral or percutaneous use

• Ultra-thin, flexible shaft designed for vocal fold anatomy

• Optimized suction port geometry for gentle, cell-preserving fat harvesting

• Fat drawn with minimal pressure into the syringe to avoid cell damage

• Compatible with injectable fillers or autologous fat

Indications:

• Vocal cord paralysis (unilateral)

• Glottic insufficiency due to atrophy, scarring, or presbylarynx

• Temporary or permanent vocal fold augmentation

• Treatment of aspiration, hoarseness, or breathy voice

The Atraumatic Vocal Cord Injection Cannula is the ENT surgeon’s trusted solution for safe harvesting and targeted delivery, combining laryngeal precision with biologic preservation for effective, lasting voice restoration.
