   - Subject has signs or symptoms of active heart failure (i.e., is NYHA class IV) at the
   time of the index procedure

   - Subject is participating in another investigational drug or device clinical study that
   has not reached its primary endpoint

   - Subject intends to participate in another investigational drug or device clinical
   study within 12 months after the index procedure

   - Subject is a woman of child-bearing potential with known intention to procreate within
   12 months after the index procedure. (Women of child-bearing potential who are
   sexually active must agree to use a reliable method of contraception from the time of
   screening through 12 months after the index procedure)

   - Subject is a woman who is pregnant or nursing (A pregnancy test must be performed
   within 7 days prior to the index procedure in women of child-bearing potential)
