Radiometric systems may comprise a radiometer, an antenna and a processor communicatively coupled together. The processor may provide a contact-focused output based on filtering or other processing of a raw radiometric output signal. The contact-focused output may facilitate determination of whether contact has been achieved and/or assessment of contact. A miniaturized reflectometer may be configured to determine an amount of reflected power from the antenna. The processor may be configured to determine a reflection coefficient of the reflected power determined by the reflectometer and to identify tissue type based on the reflection coefficient. Systems and methods for facilitating deeper temperature measurements of a radiometer are described.

Radiometric tissue contact and tissue type detection

Systems and methods for measuring and monitoring intracavitary tissue temperature. The system may include a catheter shaft with a circuit board disposed therein, the circuit board having an array of sensors disposed thereon. The catheter shaft may have an opening and an expandable structure surrounding the opening to provide a field of view of the intracavitary tissue for the array of sensors through the opening. The system may include a software-based programming system run on a computer such that a clinician may review information indicative of temperature of the intracavitary tissue, and be alerted if the temperature exceeds a predetermined threshold.

Methods, systems, and apparatus for teaching students to read and play music, particularly on a keyboard. Musical notations having upper level letter charts and lower level letter charts for playing with right and left hand playing, respectively, in combination with a tab strip for easy and quick learning and playing of the upper and lower level letter charts. The tab strip has alignment markings and letter notes whereby the alignment markings are aligned with the black keys so that the letter notes align with their respective white keys and black keys. The tab strip may be removable and transportable for playing on various different instruments.

According to some embodiments, systems for energy delivery to targeted tissue comprise a catheter with an ablation member, a radiometer configured to detect temperature data from the targeted tissue, a processor configured to determine a calculated temperature (e.g., an extreme temperature, such as a peak or trough temperature) within the tissue by applying at least one factor to the temperature data detected by the radiometer, the processor configured to compare the calculated temperature to a setpoint and an energy source configured to energize the ablation member and to regulate delivery of ablative energy to the targeted tissue of the subject based at least in part on the comparison. In some embodiments, the factor depends on at least one characteristic of the targeted tissue. Information regarding a tissue characteristic can be provided using information from an imaging set (e.g., intracardiac echo) or an electrical signal of the subject (e.g., electrocardiogram).

The present invention provides systems and methods for temperature-controlled ablation using radiometric feedback. An interface module may include (a) a processor; (b) a first input/output (I/O) port to receive digital radiometer and digital thermocouple signals from an integrated catheter tip (ICT); (c) a second I/O port to receive ablative energy from a generator; (d) a temperature display; (e) a patient relay; (f) a computer-readable medium storing instructions for causing the processor to: (i) calculate a temperature adjacent to the ICT based on the digital radiometer and thermocouple signals and operation parameters; (ii) cause the temperature display to display the calculated temperature; and (iii) close the patient relay to pass ablative energy received on the second I/O port to the first I/O port; and (g) a temperature control subsystem to regulate the ablative power based on the calculated temperature.

Systems for temperature-controlled ablation using radiometric feedback

Methods and systems are provided for detecting tissue contact prior to and/or during energy delivery to tissue. For example, the methods may include calculating temperature and detecting tissue contact based on signal(s) received from a radiometer. The radiometer may provide information about whether a treatment device is in contact with the tissue, and thus provide feedback to assist a clinician in properly contacting and treating the tissue.

Methods and systems for treating tissue that employ a radiometer for temperature measurements and use feedback from the radiometer to regulate energy being applied to the tissue are provided. For example, methods and systems are provided for calculating temperature based on signal(s) from a radiometer, which may provide useful information about tissue temperature at depth, and automatically regulating energy applied to the tissue based on the tissue temperature.

A cutter motor rotates the cutter at constant speed, and a second sensor senses changes in cutter motor torque when the cutter comes into contact with a workpiece. A computer includes a memory for storing instructions for cutting a desired pattern, and the computer causes the first, second, third, fourth and fifth motors to vary the relative position of the cutter and workpiece support to cut a pattern in the workpiece.
