Abstract: In one embodiment, a medical system includes a catheter configured to be inserted into a body part of a living subject, a display configured to provide a view of at least part of a hand of a user, and a processor configured to track a position of the catheter in the body part, render to the display a three-dimensional view of an interior of an anatomical map of the body part and a representation of the catheter inside the anatomical map responsively to the tracked position, while the display is providing the view of the at least part of the hand of the user, recognize a gesture of the at least part of the hand of the user selecting a portion of the catheter, and perform an action responsively to recognizing selection by the user of the portion of the catheter.

Abstract: A catheter calibration system includes a calibration chamber, a receiver and a processor. The calibration chamber is configured to generate a calibration magnetic field that oscillates at a first frequency. The calibration chamber includes a cavity for inserting a distal end of a catheter having one or more magnetic-field sensors. The receiver is configured to be connected to the catheter, to receive from the catheter one or more signals, which are generated by the one or more magnetic-field sensors in response to the calibration magnetic field, and to convert the one or more signals into one or more respective intermediate frequency (IF) signals having a second frequency that is lower than the first frequency. The processor is configured to receive the one or more IF signals from the receiver and to calculate catheter navigation calibration data from the one or more IF signals.

Abstract: A method includes receiving: (i) a position of a target tissue intended to be ablated in an organ of a patient and having a predefined pattern, and (ii) an energy level of an ablation signal intended to be applied to the target tissue. One or more selected ablation electrodes that, when applying the ablation signal, produce together a lesion having a shape that covers the predefined pattern, are selected in a catheter that is inserted into the organ and has an array of ablation electrodes. In response to verifying that: (i) the one or more selected ablation electrodes are positioned on the target tissue, and (ii) a contact force between the one or more selected ablation electrode and the target tissue is larger than a force threshold, the ablation signal is applied to the target tissue using the one or more selected ablation electrodes.

Abstract: There is provided a medical device comprising a low intensity electromagnetic field source to increase the respiratory control index values (RCI) of mitochondria. The medical device may be implantable, such as a cardiac rhythm management device, a stent, or a vascular graft. The device may also be worn externally, such as a treatment device having a matrix of magnetic coils that is worn on the head for the treatment of various neurological conditions.

Abstract: An internal medical device for implantation into a human or animal where the internal medical device has an electric field source that may be an active source of electromotive force such as a battery or capacitor, or may be an electric field generating material such as an electret, piezoelectric, or the like.
