The Montgomery® Laryngeal Stent is a molded silicone prosthesis designed to conform to the normal endolaryngeal surface.  The stent is constructed of radiopaque implant grade silicone that is firm enough to support the endolarynx postoperatively, yet is soft and flexible enough to ensure a conforming fit while minimizing injury to soft tissues.

The stent may be utilized as a direct support for intralaryngeal mucosal or dermal graphs to denuded areas of the endolarynx.  Each Montgomery® Laryngeal Stent includes two silicone suture buttons to support the stent externally.

INDICATIONS FOR USE:

For the prevention and treatment of laryngeal stenosis when the glottic stenosis involves the midglottis, posterior glottis, supraglottis, and subglottis, singularly or in combination.

SUPPLIED:

Sterile, 1 stent, 2 suture buttons per carton

 FEATURES:

• Implant grade silicone.
• Non-adherent smooth surface.
• Integral removal loop.
• Radiopaque color for maximum visualization.

The Montgomery® Laryngeal Keel with its unique umbrella shape, has proven useful in the repair of anterior subglottic stenosis (web), with or without vocal cord paralysis.  Use of the keel can be made following repair of stenosis, or, if use of a Montgomery® Laryngeal Stent is indicated, following removal of the stent to aid in formation of a sharp anterior commissure.

The keel also has application following hemilaryngectomy to prevent stenosis. The intralaryngeal extension of the keel is thinner than the umbrella of the extralaryngeal portion. The extralaryngeal portion, when secured to thyroid laminae with a figure-of-eight suture, covers the thyrotomy repair with its umbrella. Tightly secured, the keel prevents re-stenosis or the formation of granulation tissue.

The keel is made of soft medical grade silicone (clear or radiopaque) and is available in three sizes.

INDICATIONS FOR USE:

Repair of anterior glottic stenosis.
Formation of a sharp anterior commissure following laryngeal stent removal.
Prevention of stenosis following hemilaryngectomy.

SUPPLIED:

Sterile, 1 keel per carton

 FEATURES:

• Implant grade silicone.
• Non-adherent smooth surface.
• Available in clear or radiopaque material.

The Montgomery® Salivary Bypass Tube may be used to stent repair of cervical esophageal and hypopharyngeal strictures or to facilitate the management of fistulae resulting from a variety of causes including advanced malignancy, surgery, radiation, trauma, and caustic ingestion.  The constant bathing by saliva of tissues altered by surgery, infection, or radiation therapy is a prime factor in retarding the progress of healing and fistula closure.

INDICATIONS FOR USE:

Prevention of fistula formation following surgery.
Repair of cervical esophageal and hypopharyngeal strictures.
Management of esophageal and hypopharyngeal fistulae.

SUPPLIED:

Sterile, 1 tube per carton

PRODUCT CODES:

 FEATURES:

• Implant grade silicone.
• Non-adherent smooth surface.
• Available in clear or radiopaque material.

The Har-El Pharyngeal Salivary Bypass Tube allows the surgeon to handle a wider variety of indications for treatment of esophageal fistulae.  The tube features a unique superior funnel shape designed for anchoring at the level of the tongue base. The tube has applications for:  
1) the treatment of orocutaneous and pharyngocutaneous fistulae following head and neck oncologic resection, 
2) placement in patients with an existing fistula prior to reconstructive procedures, and, 
3) prophylactic placement in patients who are at high risk for development of a fistula.

INDICATIONS FOR USE:

Treatment of esophageal fistulae.

SUPPLIED:

Sterile, 1 tube per carton

 FEATURES:

• Implant grade silicone.
• Non-adherent smooth surface.
• Available in clear or radiopaque material

The Montgomery® Esophageal Tube is used to bridge the gap between the pharyngostome and esophagostome following laryngoesophagectomy and first stage reconstruction of the cervical esophagus.  The tube features a funnel-shaped superior end to conform to the hypopharynx, and two firm oval bands designed to ensure proper positioning and to prevent leakage of saliva after laryngoesophagectomy.

The Montgomery® Esophageal Tube has three functions:  1) it tends to eliminate the problem of profuse salivary leakage by way of the pharyngostome,  2) it maintains a widely patent pharyngostome and esophagostome, and,  3) it creates a trough between the pharyngostome and esophagostome facilitating the second stage procedure.

INDICATIONS FOR USE:

For two-stage reconstruction of the cervical esophagus.

SUPPLIED:

Sterile, 1 tube per carton

 FEATURES:

• Implant grade silicone.
• Non-adherent smooth surface.
• Available in clear or radiopaque material.
