Given Imaging ( GIVN) has a product that could revolutionize the health care industry, Jim Cramer told viewers of his "Mad Money" TV show on Speculation Friday.

The Given System is a wireless imaging system that uses disposable video capsules, he explained. And the company sells a medical device called the PillCam, a pill-sized camera that people swallow to detect internal problems.

Israel-based Given has already used its PillCam capsule for endoscopy procedures in which cameras have checked out patients' upper and lower intestines. This method, Cramer said, seems much more comfortable than checking out gastronomical problems the old-fashioned way.

In the past, Cramer said, he's made viewers money in such medical device companies as Hansen Medical ( HNSN), Micrus Endovascular ( MEND), Kyphon ( KYPH) and Intuitive Surgical ( ISRG).

In Intuitive Surgical's case, Cramer speculated on much more complicated technology, whereas in Given's case, he said he's betting on the success of a simple PillCam.

If people buy Given, they'll be taking a "calculated risk." But if the PillCam is as much of a hit as he believes it might be, the big earnings should start rolling in within a couple of years, Cramer said.

For medical devices, he said, he looks at both rigor and pending approvals. Given is coming out with PillCams for the esophagus and colon. Plus, its guidance looks promising and is a sign that there's more to come from the company.

The Next aQuantive

The next Internet-related advertising company that could get bought out is Omniture ( OMTR), Cramer told viewers.

Interestingly, the company recently had a secondary offering, in which it sold over 8 million shares at $18 and change. If Omniture can sell this amount of stock at $18, "no amount of stupid sellers can knock this thing down," Cramer said. "There's too much demand."

In addition, the company has a "great niche," he said. It makes the software that lets companies know what people are watching on the Internet. It measures trends and customer behavior on the Web.

"With Omniture, you can tell advertisers what is hot at the exact moment," Cramer said.

If he were in charge of Google ( GOOG), Microsoft ( MSFT) or Yahoo! ( YHOO), which he owns for his charitable trust, Action Alerts PLUS, Cramer said he would have bought Omniture yesterday.

Using comparative analysis, Cramer said that if Omniture's earnings are valued the same as Microsoft valued aQuantive's ( AQNT) earnings when it purchased the company for $16 billion, Omniture is a $35 stock. Omniture closed at $20.66 Friday.

However, Cramer said he's recommending Omniture here on Speculation Friday not because of its margins but because it's a likely takeover candidate.

Game Plan

Cramer urged people not to worry about the two hedge funds that recently imploded at Bear Stearns ( BSC).

While one fund was saved, the other could not be. "What really happened here is a foolish money manager made a stupid mistake," Cramer said. When there is a "wounded" manager out there, it is bad news for the fund.

All this might sound serious, but it shouldn't have any impact on Bear Stearns, he reassured viewers. In fact, he said he would buy Bear Stearns next Thursday.

The two funds, Cramer said, are not as significant to the company as people think.

Moving on with his "Game Plan," Cramer said that next week he'd look at the companies speaking at the Wachovia ( WB) and Jefferies ( JEF) conferences.

In particular, Cramer said he would consider XTO Energy ( XTO), Medco Health ( MHS) and Express Scripts ( ESRX).

Further, he said he would put half his position on Nike ( NKE) before it reports and put the second half on any weakness after earnings. Cramer owns Nike and XTO for his charitable trust, Action Alerts PLUS.

Cramer told market players to consider getting into Kroger ( KR), which doesn't seem to be getting the credit it deserves, as well as Oracle ( ORCL) and the "low-risk" play McCormick ( MKC).

On Thursday, Rite Aid ( RAD) reports. "It should continue to motor up," he said. "Buy it on any weakness between now and then."

Finally, if people don't own Research In Motion ( RIMM) already, Cramer advised waiting until after it reports next week to buy it.

In his "Mad Mail" segment, Cramer agreed with a viewer that Posco ( PKX), a stock that Warren Buffett owns, is a very inexpensive stock and a great steel company.

Moreover, he told another mailer that he believes Cummins ( CMI) is still going higher and that people should be careful with Spartan ( SPAR), which was down a couple of points today.

Lightning Round

Cramer was bullish on Huron Consulting Group ( HURN), Accenture ( ACN), Infosys Technologies ( INFY), Monster Worldwide ( MNST), Hasbro ( HAS), Mattel ( MAT), Syneron Medical ( ELOS) and Guidance Software ( GUID).

Cramer was bearish on Disney ( DIS) and Charter Communications ( CHTR).
