摘要： An implantable medical lead configured to reduce resonant currents in a resonating circuit during MRI scans and a method of manufacturing the same are disclosed herein. The method of manufacturing includes providing a medical lead comprising an electrical pathway from a tip electrode located at a distal end of the lead to a lead connector located at a proximal end and coupling a resonating circuit to the tip electrode such that the resonating circuit is in the electrical pathway for the tip electrode. Further, the method includes coupling a capacitive element to a proximal end of the resonating circuit. The capacitive element is configured to shunt at least part of an RF current induced on the electrical pathway into surrounding tissue or fluid and also works as a heat sink to spread the heat from the internal LC resonant circuit.

摘要： A filtering scheme for an implantable medical device mitigates potentially adverse effects that may be caused by MRI-induced signals. In some aspects filtering is provided to attenuate MRI-induced signals on an implanted cardiac lead that is coupled to an implanted device. In some aspects the filter may be configured to complement a capacitor circuit (e.g., a feedthrough capacitor) that reduces the amount of EMI that enters the implanted device via the cardiac lead. In some implementations the filter consists of a LC tank circuit and a series LC circuit, where the LC tank circuit is in series with the cardiac lead and a cardiac stimulation circuit and the series LC circuit is in a shunt configuration across the cardiac stimulation circuit.

摘要： A conducting sheath is provided along at least a portion of an implantable medical device lead, and preferably along substantially its entire length, for mitigating heating problems arising during magnetic resonance imaging (MRI) procedures, particularly problems arising due to a problem described herein as the “coiling effect.” During device implant, the clinician may elect to wrap or coil excess proximal portions of leads around or under the medical device being implanted. Thereafter, during MRI procedures, shunt capacitance may develop between the housing of the implantable device and insulated coils within the proximal portions of the lead that are near the device, resulting in greater lead heating during the MRI. The conducting sheath helps suppress induced currents and also reduces or eliminates shunt capacitance. The conducting sheath may be, for example, formed using a metal mesh or a conducting polymer tube incorporating non-ferrous metal powders. The sheath may be formed in ¼ wavelength segments.
摘要翻译：沿着植入式医疗装置引线的至少一部分，优选地沿着其整个长度设置导电护套，用于减轻磁共振成像（MRI）程序期间产生的加热问题，特别是由于本文所述的问题而产生的问题，如 “卷绕效应”。在装置植入期间，临床医生可以选择包裹或卷绕在被植入的医疗装置周围或之下的引线的多余近端部分。此后，在MRI程序期间，可以在可植入装置的外壳和靠近装置的引线的近端部分内的绝缘线圈之间产生并联电容，从而在MRI期间产生更大的引线加热。导电护套有助于抑制感应电流，并且还可以减少或消除并联电容。导电护套可以例如使用金属网或引入有色金属粉末的导电聚合物管形成。护套可以形成为1/4波段。
