INTRODUCTION One of a surgeon's most important tools is a highly developed sense of touch. Surgeons rely on sensations from the finger tips to guide manipulation and to perceive a wide variety of anatomical structures and pathologies. Unfortunately, new surgical techniques separate the surgeon's hands from the surgical site. These techniques include(More)
This paper presents a tactile sensor that provides transient event information at the jinger-object interface. The multi-element stress rate sensor consists of piezoelectric polymer strips molded into the surface of the rubber " skin " covering the robot finger tip. These piezoelectric elements provide localized information important to manipulation(More)
Early detection and removal of small pulmonary nodules significantly improves long term survival rates for patients with lung cancer. To aid in the localization of these tumors during video assisted thoracoscopic surgery (VATS), a tactile imaging system (TIS) is presented. The system consists of a capacitive array sensor mounted on a minimally invasive(More)
Menkes disease is an infantile-onset X-linked recessive neurodegenerative disorder caused by diverse mutations in a copper-transport gene, ATP7A. Affected patients are characterized by progressive hypotonia, seizures, failure to thrive and death in early childhood. Here, we report a case of Menkes disease presented by intractable seizures and infantile(More)
This paper presents initial results in integrating touch with vision for delicate manipulation tasks. A generalizable framework of behavioral primitives for tactile and visual feedback control is proposed. Since vision provides position and shape information at a distance, while tactile provides small-scale geometric and force information, we focus on the(More)
This paper describes a system for finding hidden arteries in remote and inaccessible locations. A tactile array sensor is located in the end of a long, 10 mm diameter probe. In a surgical application, the surgeon presses the sensor against the tissue of interest, and electronics read out the pressure distribution across the contact area at a high rate. A(More)
BACKGROUND AND OBJECTIVES Some patients with Kawasaki disease (KD) present with fever and cervical lymphadenopathy alone. The purpose of this study was to characterize the clinical features of these unusual KD patients and determine whether this is a severe form of KD associated with increased risks of intravenous immunoglobulin (IVIG) resistance and(More)
