Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Thoratec
So what: HeartWare International said its new five-ounce implantable pump, that will compete with Thoratec's HeartMate II, has seen positive results in a study. The new device has yet to be approved in the U.S., but is half the weight of the HeartMate II.
Now what: The weight difference alone is astounding for an implanted device. It doesn't sound good for Thoratec's $230 million device unless regulators hold up the new device some surgeons are raving about. I hate to sell on a down day but the increased competition doesn't look good for Thoratec in the long run.
