摘要： A medical probe includes a flexible spline assembly coupled to a distal end of an elongated shaft and including spline conductors. The spline conductors are electrically coupled to each other at a common distal termination, and each spline conductor extends proximally in an arcuate shape. The medical probe includes elongated conductors extending through the elongated shaft and being electrically coupled to a respective spline conductor. A computational system is configured to provide an output to a plurality of radiators to thereby generate alternating magnetic fields, measure electrical signals across pairs of spline conductors induced by the alternating magnetic fiels, and calculate a position and an orientation of an ellipsoid volume encompassed by the spline conductors based on the electrical signals.

摘要： The present invention provides a method of treating or alleviating erectile dysfunction in a patient. Multiple electrodes are placed within a segment of the internal iliac artery of the patient and against blood vessel wall of the internal iliac artery. Radiofrequency energy is released through at least one of the multiple electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

摘要： Disclosed are various examples and embodiments of systems, devices, components and methods configured to detect a location of a source of at least one cardiac rhythm disorder in a patient's heart. In some embodiments, electrogram signals are acquired from inside a patient's heart, and subsequently normalized, adjusted and/or filtered, followed by generating a two-dimensional (2D) spatial map, grid or representation of the electrode positions, processing the amplitude-adjusted and filtered electrogram signals to generate a plurality of three-dimensional electrogram surfaces corresponding at least partially to the 2 D grid, one surface being generated for each of selected discrete times, and processing the plurality of three-dimensional electrogram surfaces through time to generate a velocity vector map corresponding at least partially to the 2 D grid. The resulting velocity vector map is configured to reveal the location of the source of the at least one cardiac rhythm disorder, which may be, by way of example, an active rotor in a patient's myocardium and atrium.
