Fat Reduction Non-invasive
Brief summary
This study aims to generate data that conveys participant's experiences such as their satisfaction with treatment delivered by the redesigned CoolSculpting® Elite system for non-invasive fat reduction in the midsection area (abdomen and flanks) in addition to optional body areas of upper arms, inner thighs, outer thighs and/or submental area. By doing this, the study will provide insights for doctors to better inform participants about the expected outcomes when one or more body areas are considered for treatment.
Interventions
A treatment session is comprised of timed segments of cooling (treatment cycles) followed by 2 minutes of manual massage.

An AE will be considered a TESAE if it is a TEAE that additionally meets any SAE criterion. TEADE is defined as any TEAE with a reasonable possibility (Possible, Probable, or Causal relationship) that the event may have been caused by the study device. SADE is an ADE that might have led to any SAE consequences if a suitable action had not been taken or intervention had not been made. |

An AE will be considered a TEAE if the AE began or worsened (increased in severity or became serious) on or after the date (and time, if known) of the first dose of study intervention. An AE will be considered a TESAE if it is a TEAE that additionally meets any SAE criterion. TEADE is defined as any TEAE with a reasonable possibility (Possible, Probable, or Causal relationship) that the event may have been caused by the study device. SADE is an ADE that might have led to any SAE consequences if a suitable action had not been taken or intervention had not been made.
