简要总结
A prospective, interventional, single-arm study to evaluate histologic changes in skin following cryotherapy with the study device.
详细描述
This study is to include healthy adults who intend to undergo an abdominoplasty surgery, and agree to have small areas of their middle and lower abdomen exposed to cooling with the Dermal Cooling System within 180 days before the planned surgery. Exposure of multiple test sites will be completed in areas of skin that will be excised as part of the abdominoplasty procedure. Clinical assessments of the treatment sites at 1-week post-treatment and at 1-month post-treatment intervals throughout the time period prior to surgical excision, and histologic evaluation of the treated skin will be conducted to assess skin changes.

- •Subject is taking methylxanthines (phosphodiesterase-inhibitors like amino- or theophylline)
- •Artificial tanning in the area of intended treatment within 1 month (e.g., spray, lotion, tanning bed) or intention to use artificial tanning within the follow-up period.
- •Subject is unable or unwilling to comply with the study requirements.
- •Subject has any dermatological conditions or scars (other than stretch marks) within the area of planned abdominoplasty excision that may interfere with the ability to obtain test sites for treatment or evaluation.
- •Subject has a history of abnormal wound healing or abnormal scarring.
- •Subject is currently enrolled in a clinical study of any other unapproved investigational drug or device.
- •Patient is pregnant or intending to become pregnant within the next 6 months.
