The Blom-Singer Indwelling voice prosthesis is an indwelling style, clinician-placed voice prosthesis. The product is designed for laryngectomees who are unable or unwilling to routinely remove, clean, and reinsert a patient-changeable voice prosthesis.

Blom-Singer Indwelling voice prostheses are available in four product styles and offered in nonsterile or sterile, and with or without silver oxide (anti-fungal substance). Nonsterile product is not intended for primary placement procedures.

The ADVANTAGE indwelling voice prosthesis is the newest advancement in Blom-Singer voice restoration. Silver oxide has been incorporated into the prosthesis as a material preservative. The ADVANTAGE is placed by the clinician in the tracheoesophageal puncture so that routine changing of a voice prosthesis is unnecessary. It is ideal for laryngectomees who are unable or resistant to changing a removable voice prosthesis, such as the Duckbill or Low Pressure styles. The ADVANTAGE is inserted and replaced on an as needed basis by a speech pathologist or physician only.

Available in two diameter sizes, 16 Fr. and 20 Fr., and a range of lengths from 4 mm to 22 mm. Includes nonsterile voice prosthesis for secondary/replacement procedures; with insertion/cleaning accessories.

The ADVANTAGE Hard Valve Assembly prostheses are not available in England, Germany, Sweden or Netherlands.

Since its introduction in 1994, the Blom-Singer Classic Indwelling voice prosthesis has been a premier voice restoration product for laryngectomees worldwide. Like the ADVANTAGE Indwelling voice prosthesis, the Classic indwelling is intended for laryngectomees who are unable or reluctant to perform the routine removal and insertion necessary for the cleaning and maintenance of traditional, patient-maintained voice prostheses. The Classic Indwelling voice prosthesis is clinician placed; it is inserted and replaced on an as needed basis by a speech pathologist or physician only. It is available in a variety of sizes and styles.

The Low Pressure is a silicone one-way flapper valve prosthesis designed for placement in a passage between the trachea and the esophagus for voice restoration following laryngectomy. Like the Duckbill Voice Prosthesis, the one-way valve protects the airway during swallowing and opens under positive pressure so that air crosses into the esophagus to produce voice. The Low Pressure is a patient-maintained device; the patient may insert, remove and clean the device independently. Low Pressure Voice Prostheses are available in two diameters: 16 Fr. and 20 Fr. and a range of lengths from 6mm to 28mm. Special order sizes/styles available.
