The Li/SVO battery was pivotal in enabling the miniaturization and improved longevity of implantable cardiac defibrillators (ICDs). The extended lifespan of these devices significantly reduced the number of replacement surgeries required, directly benefiting patients by minimizing risks and improving quality of life. The reliability and high energy density of the Li/SVO battery were crucial for the effectiveness of ICDs in preventing sudden cardiac death.

While the Li/SVO battery's primary application was in ICDs, its impact extended to other implantable medical devices, such as pacemakers and neurostimulators. The reliable power source provided by Takeuchi's invention contributed to the overall effectiveness and safety of these devices, improving the health and well-being of patients with a variety of medical conditions.

The extended lifespan of batteries in implantable medical devices, made possible by Takeuchi's inventions, translated directly into a reduced burden for patients. Fewer replacement surgeries meant less pain, risk of complications, and disruption to their lives. This improvement in patient quality of life is a testament to the practical and human-centered impact of her research.
