High energy density film capacitors for Compact Implantable Cardioverter Defibril

描述(申请人提供)：每天有1000多名美国人死于心脏骤停(SCA)，这比乳腺癌、艾滋病和肺癌夺走的生命加起来还多。1植入式心脏复律除颤器(ICD)可以24小时监测心率并提供即时有效的治疗，从而可以将总死亡率降低23%，并为患者多提供2.5年的生命。然而，目前ICD的大小、成本和可靠性限制了它被患者接受。作为一个关键部件，电容器占据了ICD体积的三分之一以上，并将必要的除颤能量传递给心脏。战略聚合物科学公司(SPS)开发了一系列新型极性含氟聚合物介质，其能量密度(25J/cm3)至少是目前的ICD电容器(4-6J/cm3)的四倍，比其他聚合物薄膜电容器(&lt；6此外，SPS介电聚合物具有自愈特性，不含任何液体，不需要定期重整，从而提高了ICD的可靠性，延长了电池寿命。SPS正在与电容器和ICD制造商合作，将这些新材料商业化。

DESCRIPTION (provided by applicant): More than 1000 Americans die every single day due to sudden cardiac arrest (SCA), which claims more lives than breast cancer, AIDS, and lung cancer combined.1 Implantable Cardioverter Defibrillators (ICD) can provide 24-hour monitoring of heart rhythm and deliver immediate effective treatment, thus can reduce overall mortality by 23% and provide 2.5 more years of life for a patient. However, the size, cost, and reliability of current ICD limit its acceptance by the patients. As a key component, the capacitor occupies more than 1/3 of the ICD volume and delivers the necessary defibrillation energy to the heart. Strategic Polymer Sciences, Inc (SPS) has developed a series of new polar fluoropolymer dielectrics that have energy density (25 J/cm3) at least four times higher than the current ICD capacitors (4-6 J/cm3) and ten times higher than other polymer film capacitors (< 2 J/cm3), therefore they can significantly reduce the size and weight of ICD (Science 313:334 (2006), "A dielectric polymer with high electric energy density and fast discharge speed").6 In addition, SPS dielectric polymers have self-healing feature, do not contain any liquid, do not require regular reforming, thus can improve the reliability of the ICD and extend the battery life. SPS is working with both capacitor and ICD manufacturers to commercialize these new materials.
