Measure Description
Time Frame
Morbi-mortality
Time Frame: Morbi-mortality related to the device/procedure will be assessed at 365 days, in alignment with the standard of care of the participating sites.

  1. - No significant disability. Able to carry out all usual activities, despite some symptoms.
  2. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.
  3. - Moderate disability. Requires some help, but able to walk unassisted.
  4. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.
  5. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.
  6. - Dead
Morbi-mortality related to the device/procedure will be assessed at 365 days, in alignment with the standard of care of the participating sites.
