Medtronic reports that the world’s smallest cardiac monitor was successfully implanted in an office setting, part of a study to determine whether the procedure is as safe as procedures performed in a traditional hospital setting, such as an operating room, cardiac catheterization laboratory, or electrophysiology laboratory.

Medtronic’s Reveal LINQ™ wireless cardiac monitoring implant has already exceeded expectations with a potential for annual sales of $1 billion to $2 billion.

The LINQ device is inserted through a small incision via an injection device about 8 mm under the skin of the chest over the heart. It has sufficient battery life to allow for three years of continuous monitoring.
