There was/is a company known as Cardio Technologies, Inc., and as of
2001, they were located at 43 Route 43 East; Pine Brook, NJ  
07058-0710.  They developed a pneumatic assist device for people with
heart failure. A full description of this device can be found at
http://www.plexus.com/uploads/Cardio_Technologies_Product_Profile_0601CPP.pdf.

 My question is, what ever happened to either Cardio Technologies,
Inc., or their assist device.  Was it licensed, and if so, to whom? 
Did they go out of business?  An acceptable answer will contain
information no older than January, 2003 and needs to address at least
one or more of these issues.  A great answer would address all issues
as of today.

Your question was an opportunity for me to explore techniques on
finding a company that has moved, closed, or been acquired.  Here are
some leads for you, or for a paid researcher who may be able to take
these a step further to get you a current address for the company or
current status for the device.

The state of New Jersey provides free business name searches and (for
a $5 each fee) address details for registered businesses.  There are 2
businesses shown with the name Cardio Technologies ? one domestic
for-profit, one foreign for-profit.  You may also find UCC/debt
information from the same site, and there are 2 entries for Cardio
Technologies, Inc (Europe).
