Abstract: A cardiac ablation system includes a catheter and a head; the head is the ablation end of the system for cardiac tissue, and the catheter is a flexible tubular connector used by the system to couple to the head. The head has a plurality of individual ablation elements; each element provided with a contact surface for contacting cardiac tissue and a flexible support body for supporting the contact surface, wherein an energy acting part is arranged on the contact surface. The ablation element has two operating states of contraction and extension at the head position of the system; in the contraction state, a plurality of individual elements aggregate with each other and present a minimum volume; in the extension state, one or more mutually individual ablation elements open and adapt to various shape changes at the point where the cardiac tissue is contacted through the contact surfaces on each element.

Abstract: Disclosed is a method for implementing task-process-table based hardware control, which includes dividing a task that has to be implemented by a hardware circuit into multiple sub-processes, and determining the depth of the task process table according to the number of the sub-processes; according to the control information of the hardware unit corresponding to each sub-process and the number (SPAN) of clock cycles occupied by hardware processing for the sub-process, determining the bit width of the task process table and generating the task process table; starting the hardware unit corresponding to each sub-process in an order of the sub-processes, under the control of the control information in the task process table, and completing the processing of each sub-process. A device for implementing hardware control is also disclosed. The disclosure enables precise control of the hardware control flow and is of versatility.
