Trimedyne Inc., a medical laser catheter manufacturer struggling to revive flagging sales, said Monday that it has received approval from the Food and Drug Administration to market the first so-called "cold laser" for opening blocked arteries of the legs. Trimedyne in 1987 was the first company to win the FDA's approval to market a laser-powered "hot-tip" catheter to sear through fatty plaque in leg arteries.

Researchers have combined laser beams and specially coated glass to produce the first computer-type circuit that processes data with light rather than electronically, scientists say. The simple circuit is an important step in showing the feasibility of "optical computing," said Frank Tooley, a lecturer in the physics department of Heriot-Watt University in Edinburgh, Scotland. Tooley is co-author of a report on the circuit in today's issue of the British journal Nature.

Ideological and political battles over nuclear weapon research were presumed as dead as the arms race, but bomb designers and arms control advocates are facing off yet again over a massive weapon project at Lawrence Livermore National Laboratory. The lab, east of San Francisco, wants to build a laser the size of a football stadium.

Authorities in Newark arrested a man and accused him of shining a laser pointer into the cockpit of a hovering news helicopter, temporarily blinding the pilot. Pedro Vega, 36, was charged with offenses including assault and interference with transportation. The WNBC-TV helicopter was covering a traffic accident Nov. 18 when the laser was shone into the cockpit from about 1,000 feet away, said Bill Maer, a Passaic County sheriff's spokesman.

Government advisors on Monday rejected a revolutionary approach to treating heart angina--a laser that promised to relieve chronic patients' crippling pain by zapping up to 40 tiny holes into the heart itself. Some patients clearly showed relief from pain, advisors to the Food and Drug Administration said.

The State Department on Friday endorsed a Pentagon decision to fire a powerful U.S. military laser against a $60-million satellite to test its destructive power, saying it will not complicate arms control goals. "We don't have trouble with this test," spokesman James Rubin told a news briefing. "It's not a test of an anti-satellite system. It's an experiment that will not destroy the satellite, will not result in any debris, will not pose any risk," he said.

The U.S. Food and Drug Administration has approved an Irvine company's laser catheter for use in clinical trials that will study new ways to clear clogged heart arteries. Advanced Interventional Systems said its catheter is better at removing plaque from arteries than existing methods and can more closely target hard-to-reach blockages. The catheter treatment will be administered to about 200 patients in the next six months, said Tom Allen, company president.

Hewlett-Packard is to laser printers what Mike Tyson is to heavyweight boxing--the unquestioned champion. Hewlett-Packard's line of LaserJet printers dominates the desktop page printer market with more than 2 million sold. But during the past two years, IBM has been preparing itself in Lexington, Ky., to emerge as a new contender. IBM recently introduced the 4019 laser printer, which not only lists for $100 less than the H-P LaserJet Series II but boasts lower operating and maintenance costs.

The doctors said Sid Vicious, the snake, was a perfect patient. But dealing with the news media, they said, was a zoo. Sid Vicious, an 8-foot boa constrictor owned by Mission Viejo High School, underwent laser treatment at UC Irvine on Thursday afternoon for cancer of the mouth. Laser specialists and veterinarians working on the snake proclaimed the therapy a success. But "the flash cameras in the operating room were driving me crazy," one veterinarian said.
