Objectives

• Develop tracheoesophageal voice prosthesis
  insertion kit
• To be used prior to insertion of Blom-Singer
  prosthesis
• Will create kit specific to tracheoesophageal
  puncture (TEP) procedure, eliminating the
  borrowing of equipment from other fields

Relevance

• There are about 50,000 post-laryngectomy
  patients living in the U.S.
• 12,500 new cases of laryngeal cancer are
  diagnosed each year, and approximately 9,000 of
  these patients survive treatment
• We estimate 2,500 - 3,500 patients could benefit
  from our product each year

TEP Combined with Blom-Singer Voice Prosthesis

• Back of trachea punctured, creating a passageway
  between trachea and esophagus
• Blom-Singer device is inserted as a valve
  between the trachea and esophagus
• Prosthesis allows for flow of air in one
  direction while blocking backflow of food and
  liquids

Future Work

• Build prototype with shown specifications
• Dr. Day will test our prototype during his next
  TEP procedure
• Contact manufacturers about implementing our
  design and packaging it with a red rubber
  catheter
