A new DNA-based cell-transformation method could be a simpler, safer way to convert cells into beating heart cells, according to researchers at Johns Hopkins Medical Institutions. It involves no viruses and is a foolproof method to create cardiac cells that beat, they say.
The first American to be implanted with a wireless pacemaker is now walking happily around while the device communicates remotely with her doctor.
Carol Kasyjanski of New York became the first patient to receive the new pacemaker, which was made by St. Jude Medical Inc. and approved by the FDA in July. The device downloads all its information into a remote monitor in Kasyjanski's home at least once a day and the monitor automatically assesses the performance of both the pacemaker and the patient's heart. Then it uploads the information to a central server.
