摘要： A tip electrode of a catheter includes an outer wall and a temperature sensor assembly. The outer wall includes a thermally conductive multilayer printed circuit board (TCM-PCB) that includes a void. The temperature sensor assembly, which is fitted in the void of the TCM-PCB, includes a temperature sensor, one or more thermally insulating layers that surround a volume of the temperature sensor excluding one facet of the volume, and a heat conductive layer covering the excluded facet.

摘要： Described embodiments include an apparatus that includes a flexible electrically-insulating substrate, including an inner surface and an outer surface, and shaped to define (i) multiple narrower channels passing between the inner surface and the outer surface, and (ii) one or more wider channels passing between the inner surface and the outer surface. The apparatus further includes an outer layer of an electrically-conducting metal covering at least part of the outer surface, an inner layer of the electrically-conducting metal covering at least part of the inner surface, a plating layer of the electrically-conducting metal that plates the wider channels such as to connect the outer layer to the inner layer, and respective columns of the electrically-conducting metal that fill the narrower channels such as to connect the outer layer to the inner layer. Other embodiments are also described.

摘要： Described embodiments include a system that includes a current source generator and a processor. The processor is configured to drive the current source generator to supply, for application to tissue of a subject, an electric current having an amplitude that varies in accordance with a predefined function of time, such that the amplitude initially monotonically increases to a maximum value. Other embodiments are also described.

摘要： A medical apparatus, used to acquire electrical activity of patient anatomy, is provided which includes an elongated body and a tip portion coupled to the elongated body. The tip portion includes one or more inflatable sections. Each inflatable section has a plurality of electrodes disposed on one of: (i) an outer surface of the one or more inflatable sections; and (ii) an inner surface and the outer surface of the one or more inflatable sections. The one or more inflatable sections, when inflated, cause a portion of the plurality of electrodes to contact a surface of an organ and provide a pathway for physiological fluid to flow through the tip portion. In one embodiment, the tip portion is a tulip balloon tip portion. In another embodiment, the tip portion is an inflatable tip portion having one or more concentrically wound inflatable sections.
