Hurricane Sandy may have delayed trading for two days, but within the risky world of small-cap health care stocks, shares of a couple of companies wasted no time making huge moves once trading began.

On the postive end of the spectrum, shares of medical robotics company Hansen Medical (NASDAQ: HNSN) are soaring in response to a cash infusion from its larger peer, Intuitive Surgical (NASDAQ: ISRG).

In the following video, health care bureau chief Brenton Flynn discusses today's huge share price swings in the industry.
