Brief Summary

The goal of this study to better understand how the ellacor® Micro-Coring™ procedure works using an abdominoplasty, or tummy tuck surgery, model. The people participating in the study will have already decided that they want to have an abdominoplasty procedure.

The main questions this study aims to answer are:

1. how does the ellacor® procedure change skin tissue?

2. is the ellacor® device safe to use at specific treatment depths?

The ellacor® procedure will be performed on people who are going to have abdominoplasty surgery. The ellacor® treatment areas will be limited to the areas marked for removal of skin during the abdominoplasty. The treated tissue will be sent to a lab for microscopic study after the abdominoplasty procedure is complete. A minimum of 3 people will be treated in each of 2 groups for a total of 6 total participants.

3 participants in the first group will have the ellacor® procedure done 30 days before their abdominoplasty surgery. The ellacor® procedure will be done at different depths in designated locations: 4mm, 5mm and 7mm. The participants will be asked about any changes to their health or medications while on the study.

3 participants in the second group will have the ellacor® procedure done at 3 different timepoints, 30 days apart, all at the same depth of 4mm. They will also be asked about any changes to their health or medications while on the study.

Researchers will study the abdominoplasty tissue under a microscope after it has been removed from the participants. They will compare the areas treated by the ellacor® device to an area left untreated. This will reveal any changes in the skin tissue between treated and untreated areas, if they occur.

Study Groups

Cohort 1 Safety Evaluation of Treatment Depths

Each subject will be treated a single time at 4mm, 5mm and 7 mm depths at a minimum of 3 treatment areas. A non-treated control area will also be designated. Histology evaluations for all treatment areas and the control area will occur 30 days after treatment (Day 30).

Group Type: ACTIVE_COMPARATOR

ellacor® Micro-Coring procedure

Intervention Type: DEVICE

ellacor® Micro-Coring Technology is FDA approved for use by medical professionals for the treatment of moderate and severe wrinkles in the mid and lower face in adults aged 22 years or older with Fitzpatrick skin types I-IV.

Cohort 2 Multiple Treatment Histology

Each subject will be treated at a specified depth (4mm). Treatment area 1 will have 3 treatments with the study device, each treatment 30 days apart starting on Day 0. Treatment area 2 will have 2 treatments with the study device 30 days apart starting on Day 30. Treatment area 3 will have a single treatment with the study device on Day 60. A non-treated control area will also be designated. Histology evaluations for all treatment areas and the control area will occur 30 days after the area 3 treatment (Day 90).
