Endoscopic, Laparoscopic, Robotic And Minimally Invasive Force Sensor And Monitoring System

Minimally invasive ureteroscopy is a common procedure in adults, with over 10,000 procedures conducted annually in California alone. The ureteral access sheath (“UAS”), a highly effective device used to facilitate minimally invasive ureteroscopy, can injure the patient when excessive force is used during its placement. Inventors at UCI have developed a minimally invasive force sensor and monitoring system that measures force during UAS placement and can preclude injury by alerting the physician when the threshold for injury is being approached. It thus can be used for medical personnel safety training, quality control and standardization of minimally invasive ureteroscopy, as well as being applied to the passage of other catheters into natural orifices or channels./

Handheld Device to Detect Ear Infections

Acute otitis media (AOM) is a painful ear infection with a high incidence rate in children. Despite its prevalence, it is commonly misdiagnosed especially in the youngest children, in part due to obstruction of the ear canal by earwax. Researchers at UCI have developed a compact, low-cost, adaptable device to diagnose otitis media through LED light absorption. The device is able to diagnose otitis media through earwax that could be obstructing the view of the eardrum.

Near Infrared Fluorescent Imaging Used to Assess Tissue Perfusion in Surgery

Near infrared (NIR) fluorescence imaging (FI) utilizing the fluorophore indocyanine green (ICG) has become more popular for use in medical diagnostics. It is useful for assessing tissue perfusion in a number of surgeries, particularly abdominal, heart, plastic, hepatic as well as other areas of medicine. The light needed for the excitation of the fluorescence is generated by a near infrared light source which is attached directly to a camera. A digital video camera allows the absorption of the ICG fluorescence to be recorded in real time, which means that perfusion can be assessed and documented. Currently, ICG provides a visual representation of tissue perfusion as a global view. Although some efforts have been put into density analysis, no device or software currently performs dynamic evaluation of blood flow for a surgeon. Without objective dynamic measurements, practitioners are only limited to snap shot view of the static environment. This is a problem because it is the dynamics of blood flow that determines tissue perfusion, not how much blood present at a stationary point in time. Furthermore, because there are no numerical evaluations out on the market that can capture this dynamic aspect of blood flow, practitioners are forced to use the naked eye to make a clinical decision that is not only subjective, but is difficult to assess between cases.
