This is what surgical technology needs: not robots, but freezing powers. Safe, quick, and efficient, the CryoPen lets doctors put minor skin lesions on ice. Instead of applying local anesthetic and cutting away problem skin (say, a wart that won't go away), a doctor would simply fire up one of these cryogenic wands and press it to the area. In a matter of seconds, the CryoPen drops the temperature of the contacted skin tissue — a small chunk about 0.4 inch deep — to between 0°F and 40°F. The tissue then naturally becomes a blister and later a scab, healing on its own. Since it doesn't use any dangerous cryogenic chemicals like liquid nitrogen, the recently launched CryoPen is said to be safe for any exam room, potentially easing up on those copayments for referrals… and possibly a few warm martinis.
