20120271318 | ROBOT FOR MINIMALLY INVASIVE INTERVENTIONS - Rather than trying to immobilize a living, moving organ to place the organ in the fixed frame of reference of a table-mounted robotic device, the present disclosure teaches mounting a robot in the moving frame of reference of the organ. A miniature crawling robotic device can be introduced, in the case of the heart, into the pericardium through a port, attach itself to the epicardial surface, and then, under the direct control of the surgeon, travel to the desired location for treatment. The problem of beating-heart motion is largely avoided by attaching the device directly to the epicardium. The device can be used for other organs and animals. | 10-25-2012 |

20080218588 | SYSTEM FOR REMOTE GUIDANCE BY EXPERT FOR IMAGING DEVICE - Systems and methods for combining tomographic images with human vision. The systems preferably include a first assembly located proximal to an object to be imaged and a second assembly remote from the target. The first assembly is preferably able to collect a tomographic image from a target object and superimpose that tomographic image onto a direct view of the target object. The first assembly also includes components that allow the transmission of the tomographic image to the remote assembly. At the remote location, a highly trained expert may interact with the captured image by placing electronic markers on the image via an electronic interface. The captured image plus electronic marker are then preferably transmitted back to the local site via a second transmitter-receiver. The local user may use the electronic marker to guide his actions during the appropriate task. The systems have particular utility in the medical field where a trained clinician at a remote location may provide guidance to an untrained individual in performing a medical procedure on a patient. | 09-11-2008 |
20080226134 | FINGERTIP VISUAL HAPTIC SENSOR CONTROLLER - Systems, methods and devices for capturing environmental image data and providing tactile feedback about the visual environment to a user. One or more image sensing devices are mounted on various appendages of a user and are used to sense the environment. The image data is sent to a computer vision system where it is processed in order to identify specific objects within the environment. When the computer vision system makes such an identification it may send a signal to a haptic stimulator mounted on a user's appendage or may be used to control an object in the environment. | 09-18-2008 |

20080218743 | COMBINING TOMOGRAPHIC IMAGES IN SITU WITH DIRECT VISION IN STERILE ENVIRONMENTS - A device for combining tomographic images with human vision using a half-silvered mirror to merge the visual outer surface of an object (or a robotic mock effector) with a simultaneous reflection of a tomographic image from the interior of the object. The device maybe used with various types of image modalities including ultrasound, CT, and MRI. The image capture device and the display may be enclosed in a sterile container (e.g., a probe bag) and a mirror and mirror housing may be separately attachable to the image capture device and display. In these embodiments, the mirror may be disposable and the sterility of the overall imaging device is maintained. | 09-11-2008 |
