MRI and combined use possible leadless heart pacemaker

摘要

Topic The shrubbery type heart pacemaker system which it tries to be able to operate safely in MRI imaging over wide-ranging MRI condition is offered.SolutionsThe shrubbery type electric battery type leadless pacemaker or the organism stimulus device which can include optional ones among many features is offered. One feature of the organism stimulus device is that the organism stimulus device operates safely under wide-ranging MRI condition. One feature of the organism stimulus device, during MRI inspecting although excessive picture arch fact is evaded, is that the organism stimulus device has the sufficiently small all product. As for another feature of the organism stimulus device, in order to hold down heating the organization in the electrode advanced region of the organism stimulus device to minimum, it is to make the route length between the electrodes decrease. Furthermore as for another feature of the organism stimulus device, the electric current loop area inside the organism stimulus device, faradism inside the organism stimulus device and the extent which decreases voltage is small thing during MRI inspecting. Also the method of being related to the use of the organism stimulus device is included. Selective figure Figure 1
