to five months after treatment. Surgical intervention may be required.
• Late-onset pain with a typical onset several days after a treatment and resolution within several weeks.
• Freeze burn: First and second degree freeze burn may occur during treatment. It typically resolves without
sequelae with proper care.
• Vasovagal symptoms: Dizziness, lightheadedness, nausea, flushing, sweating, or fainting during or
immediately after the treatment.
• Subcutaneous induration: Generalized hardness and/or discrete nodules within the treatment area, which
may develop after the treatment, and may present with pain and/or discomfort.
• Hyperpigmentation: Hyperpigmentation may occur after treatment. Typically, it resolves spontaneously.
• Hernia: Treatment may cause new hernia formation or exacerbate pre-existing hernia, which may require
surgical repair.
• Treatment Area Demarcation (TAD): An aesthetic outcome of treatment in which the patient experiences
excessive fat removal in the treatment area, resulting in a visible disruption to the continuous contour of
fat, or unwanted indentation in the treated area.
• Cold panniculitis: Cold panniculitis results from injury to adipose tissue exposed to cold and may result in a
mild to severe inflammatory response. In mild cases, the symptoms are self-resolving and may include
redness, swelling, skin nodules, warmth, tenderness, and possible low-grade fever. These cases typically
resolve without long-term sequelae. In more severe cases, an intense inflammatory response may result in
more extensive tissue damage, including fat necrosis, which may require medical or surgical intervention.
Freeze burn, vasovagal symptoms, and hyperpigmentation were observed during clinical trials, while the others
were reported in post market use.
Potential for Tissue Damage
The system operates at temperatures below 0°C, which can freeze tissue. Therefore, the system monitors
tissue during cooling and employs multiple safety features including the Freeze Detect
®
system, to minimize the
risk of damage to tissue. In spite of these measures, on rare occasions, the Freeze Detect system can detect a
possible freeze condition.
The Freeze Detect system is comprised of several features, including thermal sensors and proprietary
algorithmic software. Freeze Detect is an integral part of the CoolSculpting System and is automatically
employed when a treatment is initiated. When the Freeze Detect system detects a possible freeze condition, it
stops the treatment and displays a Z409 message. If you receive this message, remove the applicator and
gelpad or gel, and assess the tissue before taking further action. If you receive a second Z409 message for one
treatment site, discontinue the treatment. Failure to follow instructions could result in injury to the patient,
including first- or second-degree burns. Second-degree burns or complications of second-degree burns may
result in hypopigmentation.

About the System
The system is comprised of a control unit, a surface or vacuum applicator, and supplies. The applicators, foam
borders, gelpads, gel, liners, pretreatment skin wipes, and securement systems are patient -applied parts.
During a treatment, the operator applies a gelpad or gel and applicator to the patient’s skin. The vacuum
applicator draws tissue into the applicator cup and holds the tissue against the cooling surfaces of the
applicator; the surface applicator does not use vacuum pressure. The operator starts the treatment. Sensors in
the cooling surfaces of the applicator monitor the skin surface, providing feedback that controls the rate of
