MAGNETIC PELLETS AND EXTERNAL ELECTROMAGNETIC DEVICE FOR ASSISTING LEFT VENTRICULAR CONTRACTION, METHOD OF PELLET INSERTION, AND METHOD OF VENTRICULAR ELECTROMAGNETIC ASSISTANCE

摘要

Magnetic pellets (10) for use in treating a patient's congestive heart includes a contact portion (14) and a plurality of wings (12). The pellets (10) are implated into the heart wall (25,27).
