Robotic Surgery   Robotic-assisted surgery may well be the most significant story in medical circles since the Jarvik artificial heart hit the headlines years ago. Using small surgical cuts, this minimally invasive procedure leads to faster recovery and less pain, bleeding, and risk of infection. You can expect to leave the hospital after an overnight stay and walk within a day following kidney or bladder removal, once considered major surgeries. Robotic-assisted techniques have even been extended to certain heart surgeries.

Robotics allows surgeons to work at a console only a few feet away from the operating table, remotely manipulating robotic arms at the bedside. The primary advantage is reducing the impact of hand tremors on surgical ...
