Medical device company MiRus led this week's massive funding rounds with a $1.5 billion corporate investment from Boston Scientific. The deal gives Boston Scientific a 34% equity stake in the Georgia-based firm developing orthopedic and spinal technologies. Physical tech dominated the top deals as venture capital continues flowing into healthcare and AI sectors.

Artificial intelligence startups claimed multiple spots on the list.

This week's deals signal investors are still willing to fund high-growth companies despite market volatility.
