Immersion delivers first-ever haptic medical simulation for new lung cancer diagnostic procedure

San Jose 04 March 2009Immersion Corporation, a developer and licensor of touch feedback technology, has introduced a new way to accurately and efficiently train pulmonologists and thoracic surgeons on a breakthrough emerging procedure for diagnosing and staging lung cancer. The maker of the industry's only haptic-enabled bronchoscopy simulator delivered a new module, Endobronchial Ultrasound with Transbronchial Needle Aspiration (EBUS-TBNA). It provides realistic multi-modal (sight, sound, and touch) virtual reality training for this difficult but highly accurate procedure that diagnoses and stages lung cancer, the cause of the most cancer deaths worldwide. It is the first and only haptic-enabled endoscopy simulator designed for EBUS-TBNA.

"This market-first simulation keeps Immersion at the forefront of innovation in highly sophisticated medical training that helps improve the quality of health care all over the world", stated Daniel Chavez, senior vice president and general manager of Immersion's Medical line of business. "By combining realistic touch feedback with our virtual reality environments that provide true-to-life simulation, Immersion is helping more and more doctors become skilled at critical new techniques that can save lives every day."

"Endobronchial ultrasound has been shown to be effective in significantly increasing the yield of sampling enlarged thoracic lymph nodes and facilitating the staging of lung cancer in a minimally-invasive fashion. Unfortunately, the learning curve for EBUS is fairly steep", stated Dr. Momen Wahidi, MD, MBA, and Director of Interventional Pulmonology at Duke University Medical Center, Durham, North Carolina. "The EBUS-TBNA simulation model created by Immersion should greatly enhance the learning of the large number of pulmonologists and thoracic surgeons who are eager to learn EBUS-TBNA and introduce it to their practice."

EBUS has been shown to be an effective tool for imaging and sampling mediastinal nodes. However, due to several factors such as an angled camera view and difficult to interpret ultrasound images, it requires intense training and can take over 50 procedures to learn. By using advanced virtual reality simulation to train, medical schools and institutions can provide a risk-free, cost-saving, and highly effective way for medical students, residents, and practising physicians to master the EBUS procedure.

Immersion provides the most cutting-edge methods of training for challenging procedures that help ensure better health care outcomes for a population that faces staggering mortality rates. Lung cancer has an extremely high mortality rate of 94 percent in the United States, with approximately 160.000 deaths occurring from 170.000 cases diagnosed each year. According to the World Health Organization, lung cancer causes more deaths worldwide than any other cancer. It accounts for about 1,4 million deaths each year, or 17,7 percent of all cancer deaths.

EBUS-TBNA provides a minimally invasive alternative to mediastinoscopy, the traditional method of staging lung cancer. Additionally, the image-guided component increases yields versus traditional "blind" TBNA techniques. EBUS-TBNA can offer ongoing cost savings by avoiding the need for mediastinoscopy and other more expensive procedures for some patients.

Endoscopic and bronchoscopic procedures are commonly practised medical procedures today. However, the motor skills necessary to perform these are difficult to train and assess. Immersion's EBUS-TBNA module for its EndoscopyVR System provides several key benefits, including:

  • Virtual patient anatomy derived from actual patient CT images to present a true-to-life environment.
  • Real-time ultrasound imaging with integrated colour Doppler.
  • Bronchoscope and TBNA needle that feels and handles realistically to simulate actual interactions experienced in patients, which reduces the need for cadavers.
  • Simulations that include realistic TouchSense force feedback, allowing the user to experience the feel of the real procedure.
  • Independent learning that reduces the cost of supervision. Realistic images and audio feedback combine with touch feedback to involve three key senses.
  • Modules with increasingly challenging cases to broaden experience and test progress. Physics-based simulation presents the trainee with digital virtual reality patients that respond accurately, adding to the level of realism.
  • Modular design allowing cost-effective medical simulation of multiple procedures on the same platform.
  • Physiological responses to vital signs based upon the user's interactions as well as medications administered during the procedure.
  • Medical simulators that are mobile and convenient for use in the training institution.

Immersion designs, manufactures, and markets computer-based surgical simulation training systems worldwide. The medical and surgical simulators integrate proprietary computer software and tactile feedback robotics to create highly realistic medical simulations that help train clinicians. The company's key product lines are the LaparoscopyVR surgical simulation system, Endoscopy AccuTouch simulator, CathLabVR surgical simulator, and the Virtual IV system.

Founded in 1993, Immersion Corporation is a recognized expert in developing, licensing, and marketing digital touch technology and products. Using Immersion's advanced touch feedback technology, electronic user interfaces are more compelling, entertaining, and in many applications, safer and more productive. Immersion's technology has helped manufacturers develop innovative and creative solutions for products such as hundreds of video games and leading video console gaming systems, medical training simulators installed around the world, driver controls for automotive manufacturers, and mobile phones, such as those from LG and Samsung. Immersion's patent portfolio includes over 700 issued or pending patents in the United States and other countries.
