Abstract: Methods and systems are provided for illuminating various materials using an LED system. These methods and systems can be applied to a plurality of materials, including biological entities, and may be employed to effect one or more changes in the illuminated material. Exemplary systems may be particularly configured and suitable for use in medical applications, including diagnostic and therapeutic interventions.

Abstract: The systems and methods disclosed herein relate to sources of diffuse illumination for providing substantially uniform illumination to a surface. The diffuse illumination arises from varying the diffusion angle of light generated by an LED system. To vary the diffusion angle, a translucent member is placed between the LED system and the surface. Light emitted from the LED system across the translucent member can subsequently can uniformly cover the surface.

Abstract: An actuator is used in a surgical simulation system that simulates the catheterization of cardiac or peripheral vasculature. The simulation system provides haptic feedback to a user of a catheter or similar elongated object coupled to the system. The actuator includes sensors that generate sense signals indicative of axial translation and rotation of the object by the user. The sense signals are provided to a workstation executing a simulation program. In response to the sense signals, the workstation calculates axial forces and torques to be applied to the object as haptic feedback to the user, and generates drive signals representing the calculated axial forces and torques. Mechanisms within the actuator respond to the drive signals by applying corresponding axial force and torque to a rigid tube that is mechanically coupled to the object. One embodiment of the actuator includes a carriage assembly for holding the rigid tube between a pair of opposed pinch wheels.

Abstract: Disclosed herein is a current control for a lighting assembly, which may be an LED lighting assembly, which may be a pulse width modulated (“PWM”) current control or other form of current control where each current-controlled unit is uniquely addressable and capable of receiving illumination color information on a computer lighting network. In an embodiment, the invention includes a binary tree network configuration of lighting units (nodes). In another embodiment, the present invention comprises a heat dissipating housing, made out of a heat-conductive material, for housing the lighting assembly. The heat dissipating housing contains two stacked circuit boards holding respectively the power module and the light module. The light module is adapted to be conveniently interchanged with other light modules.

Abstract: A master/slave system is used for performing a surgical procedure such as theterization of cardiac or peripheral vasculature. Movements of catheters or similar tools within a patient are remotely controlled by a surgeon, and the surgeon receives haptic or tactile feedback caused by the movement of the tools within the patient. The system employs a master actuator with cylindrical controls and a slave actuator that engages the tools. The master actuator and slave actuator are electrically coupled to electrical interface circuitry by drive signals and sense signals. A fluid system is coupled to the slave actuator by fluid-carrying tubes for the delivery of contrast and other solutions to be injected into the vasculature for improved imaging and also to pressurize the balloon on a balloon catheter.
