Device that Enables Fast, Precise Creation of Tracheal Window

Invention
The University of Florida is actively seeking companies interested in commercializing a novel device to help ENT and emergency room physicians quickly and accurately create tracheal windows during tracheotomy. ENT surgeons perform more than 60,000 tracheotomies annually, making this one of their most frequent procedures. The most common method currently employed to create a window uses a combination of scalpel and heavy scissor dissection. However, this practice is difficult and extremely risky; the slightest imprecision can result in hypoxia and brain injury. Since this surgery is often performed under emergency conditions in which the patient is experiencing severe breathing difficulties, there is a need for an improved methodology. Researchers at the University of Florida have developed a “tracheal punch” device that enables surgeons to safely, rapidly create a precise window during a tracheotomy.
Applications
Fast, precise creation of a tracheal window during surgery
Advantages
# Provides a mechanism for creating an appropriately-sized rectangular window in every patient regardless of circumstances, thereby reducing imprecision and associated consequences such as brain damage
# Improves efficiency and safety of tracheotomy, providing greater patient survival rates
# Scientifically reduces hypoxia and associated brain injury, enhancing and prolonging patients’ lives
# Compact, easy to use device provides opportunity for broad market application
Technology
In elderly patients with calcified cartilage or in emergency tracheotomy cases where the airway in a conscious patient changes with respiration, using scalpel and heavy scissor dissection to create a tracheal window can be difficult. The “tracheal punch” device created by University of Florida researchers increases the speed and accuracy with which surgeons can create tracheal windows. After making an initial horizontal scalpel incision between cartilaginous tracheal rings (the standard first step to enter the airway), the surgeon inserts the device through the incision with a single handle squeeze maneuver called a “punch” to create a window in the trachea. This maneuver is similar to using a paper punch to make a hole in a sheet of paper. The device can then be sutured to the skin to assist with tracheotomy tube replacement.
To discuss this technology with a licensing officer call (352)392-8929 or email jmuir@ufl.edu and ask about record UF ID: 10785

Recycling Single-Use Medical Devices Saves Money But Raises Concerns
By LINDA A. JOHNSON AP Business Writer
TRENTON, N.J. Jul 31, 2006 (AP)— For eight months during his infancy, Sean Van Duyn gagged, retched and vomited daily. Now 6, the Winter Haven, Fla., boy still can't eat or drink by mouth, instead being fed by a permanent tube in his belly.
Beset by multiple medical problems in his first months, the boy had to have a breathing tube inserted through a hole cut in his neck. The gagging began and continued until his mother, Susan, discovered the tube was misshaped at the end and had been poking the back of his throat the whole time. The tube was replaced, but by then Sean's developing brain was programmed not to swallow; he still cannot.

BENIGN TRACHEAL STENOSIS by Susan A. Eicher, M.D.
Posted by: jill on Sunday, April 25, 2004 - 10:07 AM

Tracheal stenosis is a relatively uncommon problem that has a variety of etiologies. It frequently has an insidious onset, and the early signs and symptoms may be disregarded or mistaken for a variety of other disorders. Shortness of breath on exertion, which may progress to dyspnea at rest, a brassy cough, recurrent pneumonitis, wheezing, stridor, and cyanosis may all be a part of the clinical presentation. because many of these symptoms, especially dyspnea on exertion and wheezing, can be easily attributed to other respiratory disorders such as chronic bronchitis and asthma, the patient's past medical history becomes particularly important.

Tracheotomy in children – indications and complications
Lidia Zawadzka-Głos, Mieczysław Chmielik
Department of Paediatric Otorhinolaryngology, The Medical University of Warsaw, Poland
Head: Prof. Mieczysław Chmielik M.D.
Summary
Tracheostomy is a life-saving procedure when performed with an appropriate indication and surgical technique. There is a limited indication for tracheostomy procedures in paediatric surgery. It is rarely applied to the paediatric patient because they can be kept intubated for a longer period compared to adults. Indications for tracheostomy are prolonged intubation, subglotic stenosis, general body trauma, tracheomalasia, cervical tumour pressing the trachea and larynx, congenital diseases of the larynx, burn injuries of the trachea, and foreign body aspiration. In the last decade the number of cases with tracheotomy increased due to the development of new intensive care units, the use of mechanical ventilation, and the increasing number of patients needing prolonged ventilation support. Tracheotomy in children has been associated with significant operative and post-operative complications. When long-term tracheotomy is needed, parent education, together with special equipment and environment may allow the return of the tracheotomised child to home in secure conditions.

Dilatational Tracheotomy – minimally-invasive, bed-side, inexpensive – but safe?

Brussels, Belgium. 20-23 March 2001
Introduction
The dilatational tracheotomy becomes more and more a standard procedure in many ICUs. Complications of the dilatational tracheotomy are subject of controversial discussions. The estimation leads from 'inappropriate for the critically ill' up to 'even without surgical background to practice easily and safely'.
On the bases of the experience of 80 self-practiced dilatational tracheotomies we critically report observed complications, possible complications and in conclusion we present the 'quality-standard for dilatational tracheotomy'.

Hyoid Suspension for Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) syndrome is a life-threatening condition with a reported prevalence of up to 4% among adult men in the United States. Upper airway obstruction most often results from collapse of excess soft tissue in the soft palate, tonsillar pillars, tongue, tongue base, and hypopharyngeal walls. Surgical therapies for hypopharyngeal obstruction and collapse range from midline glossectomy to mandibular advancement and hyoid suspension. These complex, invasive procedures entail considerable morbidity and exhibit moderate results. We introduce the technique of hyoid suspension / myotomy (HSM) as an adjunctive procedure to relieve or ameliorate OSA resulting from an obstructive tongue base.
