Abstract: A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum and a ventilation element for generating a simulated breeze to artificially emulate conditions in an outside environment of an enclosed structure in which the lighting system is disposed. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day. The controller also controls the generated simulated breeze of the ventilation element to be one of a cool breeze and a warm breeze to artificially emulate the outside environment in correspondence with the artificially emulated daylight spectrum. The system further includes a networking facility that facilitates data communication with at least one external resource.

Abstract: A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature. The esophageal temperature is monitored utilizing an esophageal probe which may have any number of temperature sensing members. The esophageal probe may also have pre-formed shape. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature (from any thermistor), the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. The method and system may also be used during cryoablations.

Abstract: A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature, the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. In one embodiment, an esophageal cooling means is incorporated for cooling the esophagus during the procedure. If the temperature starts to increase a cooling means can be initiated and/or an ablation interrupt means is activated based on pre-determined events.

Abstract: An apparatus and method for stopping of ablation energy delivery to tissues during cardiac ablation procedures provides added safety. The apparatus uses control switch mechanism comprising relay switch and circuitry inserted between the ground patch and ablation generator. Alternatively, the control switching means can be on the catheter side of the ablation circuit. The switching mechanism is connected to a computer, which controls the on-off switch based on pre-determined conditions. When the control switch part of the circuit is opened, the ablation generator shuts of immediately. The software in the computer is configured, such that the computer controlled stopping of energy delivery only occurs when patient safety is at risk.

Abstract: Method and system of increasing safety of ablation of cardiac arrythmias, especially AVNRT and antero-septal accessory pathway ablations. A computer based system acquires, conditions, and analyzes the timing relationships between atrial and ventricualr signals during normal sinus (NSR) and junctional rhythms (JR) during ablation. If the timing analyses determines a safety issue, such as loss of retrograde conduction during junction rhythm, while slow pathway modification is being performed, the computer electronically disconnects the ablation circuit. This immediately stops the energy delivery to the tissues and provides a chance to reposition the ablation catheter tip to a more safer location. The ablation may be using radiofrequency (RF), cryoablation, or with high intensity focused ultrasound (HIFU). The functionality and circuitry of the system may also be incorporated within an ablation generator, EP recording and monitoring system, or a cardiac mapping system.
