—Palpating tissues and organs to identify hidden tumors or to detect buried vessels is not a viable option in laparoscopic surgery due to lack of force feedback. So far, research toward restoring tactile and kinesthetic sensations in minimally invasive surgery has focused on the distal sensing element or on the proximal rendering of haptic cues. In this(More)
In an open surgery, identification of precise margins for curative tissue resection is performed by manual palpation. This is not the case for minimally invasive and robotic procedures, where tactile feedback is either distorted or not available. In this paper, we introduce the concept of intraoperative wireless tissue palpation. The wireless palpation(More)
—Medical devices like the Implantable Cardioverter Defibrillator (ICD) are life-critical systems. Malfunctions of the device can cause serious injury or death of the patient. In addition to rigorous testing and verification during the development process, new medical devices often go through clinical trials to evaluate their safety and performance on sample(More)
The purpose of this study is to validate a Jacobian-based iterative method for real-time localization of magnetically controlled endoscopic capsules. The proposed approach applies finite-element solutions to the magnetic field problem and least-squares interpolations to obtain closed-form and fast estimates of the magnetic field. By defining a closed-form(More)
Ensuring that medical devices, such as pacemakers and implantable cardioverter defibrillators (ICDs), deliver the appropriate therapy only when necessary is made difficult by complex software and variability conditions between patients. Because of patient condition variability, safety recalls have affected over 600,000 devices between 1990 and 2000 [1]. Of(More)
Gastric cancer is the second leading cause of cancer death worldwide and screening programs have had a significant impact on reducing mortality. The majority of cases occur in low- and middle-income countries (LMIC), where endoscopy resources are traditionally limited. In this paper, we introduce a platform designed to enable inexpensive gastric screening(More)
Over the last decade, researchers have explored the design space of medical capsule robots: devices that operate autonomously within the human body and can monitor, diagnose, prevent, and cure diseases. Medical capsule robots are severely resource constrained devices in size, power, and computational capacity. As such, the design process is time consuming(More)
