At the 64th annual Scientific Sessions of the American Heart Association (AHA), held in Anaheim, Calif, many presentations dealt with the safety and efficacy of alternative devices designed during the past few years to remove fatty deposits or prop open arterial walls after percutaneous transluminal coronary angioplasty (PTCA).

Experimental Now, Clinical in '92?
The major devices include specialized balloon and laser catheters, mechanical atherectomy or ablation devices, and metallic and bioabsorbable stents. With one exception (the Atherocath, which has
