20150305623 | METHODS FOR LOCALIZING AND TREATING A PARATHYROID ADENOMA - Parathyroid adenomas may be identified using optical probes which distinguish the diseased tissue from adjacent healthy tissue. Spectroscopic properties of the tissue may be used to distinguish healthy from diseased tissue. Traditional surgery to remove the parathyroid adenoma may be avoided by using techniques to occlude the blood supply to the diseased tissue. Occlusion may be accomplished by applying energy to the blood vessel such as with radiofrequency energy, ultrasound energy or laser energy. Cryogenic probes may also be used to occlude the blood flow. Clips, sutures or other mechanical mechanisms may also be used to occlude the flow, thereby destroying the diseased tissue. | 2015-10-29 |
20150305624 | FLUORESCENCE FILTER SPECTRUM COMPENSATION - A device provides incident light on oral structures, switchably between two states. In the first state, incident light causes autofluorescence of byproducts of decay, and an optical filter between the oral structures and either the user's eyes or a visualizing apparatus yields visually distinguishable appearances for that autofluorescence depending on whether the tissue is healthy or unhealthy. In the second state, the incident light is of a color composition that yields a substantially “white” spectrum after passing through the filter. | 2015-10-29 |
20150305625 | Flexible and Scalable Sensor Arrays for Recording and Modulating Physiological Activity - An implantable sensor array incorporates active electronic elements to greatly increase the number of sensors and their density that can be simultaneously recorded and activated. The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors/effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors/effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors/effectors on the array. | 2015-10-29 |

The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools.

In addition, a method for adjusting thermal dilution readings to compensate for varying shunt catheter depth is shown and for determining a steady state of the thermal dilution readings.
