摘要： A system includes a display, an input device, and a processor. The processor is configured to present to a user, on the display, a GUI that illustrates multiple electrodes disposed on an expandable frame of a multi-electrode catheter, and indicates which of the electrodes is active and which of the electrodes is inactive. The processor is further configured to (a) receive, via the input device first user input that chooses between a single-electrode-selection mode and a fan-selection mode, (b) when in the single-electrode-selection mode, receive via the input device second user input that specifies for activation or deactivation individual ones of the electrodes, and (c) when in the fan-selection mode, receive via the input device third user input that specifies for activation or deactivation an angular sector including two or more of the electrodes, and activate and deactivate the electrodes responsively to the first, second and third user inputs.

摘要： A system includes a signal generator, configured to pass a generated signal, which has two different generated frequencies, through a circuit including a bidirectional semiconductor device. The system further includes a processor, configured to identify, while the generated signal is passed through the circuit, a derived frequency, which derives from the generated frequencies, on the circuit, and to generate, in response to identifying the derived frequency, an output indicating that a property of the bidirectional semiconductor device is asymmetric.

摘要： A haptic feedback device receives a signal reflecting pressure exerted by a medical tool against an anatomical surface. A fastener secures the feedback device to, for example, a wrist of an operator. A haptic exertion component exerts haptic stimulation to the operator based on the received signal such that when the received signal reflects a pressure being exerted by the medical tool against the anatomical surface of a patient is in a defined range for operation of the medical tool, the exertion component exerts haptic stimulation at a predetermined level that indicates pressure of the medical tool is being exerted in the defined range. Otherwise, the exertion component does not exert a level of haptic stimulation that is equal to or more than the predetermined level or the exertion component exerts a level of haptic stimulation to the operator that is more than the predetermined level.

摘要： An apparatus includes two or more medical systems and a low impedance path. The two or more medical systems have respective electrical outputs and respective separate isolation grounds each isolated from power lines and from earth ground, wherein the two or more medical systems are electrically coupled one with the other via the patient. The low impedance path connects the separate isolation grounds of the medical systems to one another, causing one or more leakage currents to flow via the low impedance path instead of via the patient.

摘要： A signal return-path symmetry measurement apparatus includes a transformer and monitoring circuitry. The transformer is coupled to first and second return-path electrodes that are attached to a body of a patient and serve as a return path for an electrical signal applied to the patient. The transformer is configured to generate a return-path-difference electrical signal responsive to a difference between electrical signals returning from the first and second return-path electrodes. The monitoring circuitry is configured to generate an electrode symmetry measure responsive to the return-path-difference electrical signal.

摘要： An apparatus includes a controllable signal source and a processor. The controllable signal source is configured to apply an Alternating Current (AC) signal to multiple electrodes of a multi-electrode catheter immersed in an aquatic solution. The processor is configured to, responsively to the applied AC signal, estimate a respective surface impedance or a respective electrical noise level of each of the electrodes. The processor is further configured to disconnect each electrode, independently of other electrodes, when the estimated surface impedance or electrical noise level of the electrode drops below a preset value.

摘要： In a flexible catheterization probe a resilient member couples the tip to the distal portion of the probe and is configured to deform in response to pressure exerted on the tip when engaging tissue. A position sensor in the distal portion of the probe senses the position of the tip relative to the distal portion of the probe. The relative position changes in response to deformation of the resilient member. The position sensor generates a signal indicative of the position of the tip responsively to a magnetic field produced by a magnetic field generator located in the position sensor. The position sensor has a first coil of conductive wire having first windings, and three second coils of conductive wire having respective second windings. The second coils are symmetrically distributed about the longitudinal axis of the first coil.

摘要： Methods and systems of catheterization include a flexible catheter adapted for insertion into a heart of a living subject. The catheter has a lumen for passing an electrically conductive fluid therethrough with the fluid exiting the catheter at the distal portion. The lumen is connectable to an irrigation pump to form a fluid communication therewith. A fluid reservoir connected to the lumen supplies the fluid to the catheter. Electrocardiogram circuitry is connectable to the subject for monitoring electrical activity in the heart. An electrically conductive cable diverts induced charges in the fluid from the catheter electrodes, for example by connection to an isolated ground of the electrocardiogram.

摘要： A wiring assembly (111) includes a differential input port (60a,60b), a differential output port (62a,62b), and first (54a,54b) and second (55a,55b) pairs of electrical conductors. The differential input port (60a,60b) is configured to receive a differential signal from a sensor at a first end of the wiring assembly (111). The differential output port (62a,62b) is configured to output the differential signal at a second end of the wiring assembly (111). The first and second pairs of electrical conductors are laid out in a three-dimensional (3D) crossover configuration relative to one another and configured to conduct the differential signal from the first end to the second end, and to cancel pickup of a magnetic field by the wiring assembly (111). The electrical conductors of each pair are connected to one another at the first end and at the second end.
