Electrophysiology devices (think ablation catheters and medical lasers) should reach $4.4 billion in global sales by 2015 as the sector approaches nearly double-digit growth, concludes a new industry report. Broken down, North America will generate 35% of the total and Europe is expected to produce 30%, RnR Market Research's report states. But the Asia-Pacific region--particularly China, India and South Korea--will be the fastest growing region in the coming years and will catch up in a major way, the report predicts. Case in point: The sector's compound annual growth rate through 2015 should hit 9.7%, but that number climbs to 10.8% in the Asia-Pacific region on its own. Item
