摘要： A spring assembly usable with an intravascular catheter can include a tubular body, two mounting surfaces, and a compressible framework. The tubular body extends along a longitudinal axis and is sized to traverse vasculature. Each mounting surface can be configured to engage a substantially planar electrical circuit and is positioned in the tubular body each in a respective plane perpendicular to the longitudinal axis. The mounting surfaces face toward each other in opposite directions. The compressible framework extends between the first and second mounting surfaces. The spring assembly can further include a pair of electrical circuits mounted to the pair mounting surfaces. Each electrical circuit can include an inductive coil such that the pair of electrical circuits is a distance transducer. A change in distance between the pair of electrical circuits can be detected when the compressible framework is compressed and/or bent.

摘要： A system for electrophysiological measurement includes a probe having a distal end configured for insertion into a body cavity of a living subject and including an array of electrodes that are disposed along the distal end and are configured to contact tissue at multiple locations within the body cavity. A processor is configured to acquire signals from the electrodes over a period of time during which the probe moves within the body cavity, to compute, in response the signals, metrics that are indicative of a respective quality of contact between each of the electrodes and the tissue over the period of time, and to output an indication of the metrics to a user of the system.

摘要： A radio frequency (RF) ablation system is disclosed including signal generator circuitry and control circuitry. The signal generator circuitry is configured to generate a plurality of RF ablation current signals each having a respective phase and a respective amplitude. The control circuitry is configured to reduce crosstalk between a first RF ablation signal of the plurality of RF ablation current signals and a second RF ablation signal of the plurality of RF ablation current signals by adjusting the respective phase of the first RF ablation signal in relation to the respective phase of the second RF ablation signal such that the respective phase of the first RF ablation signal is different than the respective phase of the second RF ablation signal.

摘要： A method for radiographic imaging of a body cavity includes imaging the body cavity using computerized tomography (CT) to form a CT image, registering a tracking system with the CT image, inserting into the body cavity a guidewire, including a position sensor, operating in the tracking system, attached to a distal end of the guidewire, in response to signals from the position sensor acquired by the tracking system, displaying a position of the distal end of the guidewire on the CT image. The method further includes assigning voxels within a predefined imaging volume relative to the distal end and having a radiodensity less than a predetermined threshold to have a uniform radiodensity of a predefined default value, incorporating the voxels with the assigned predefined default value into the CT image so as to form an updated CT image, and displaying the updated CT image.
