An interventional study of ellacor® Micro-Coring procedure in Wrinkle, Rhytides and Histopathology, sponsored by Cytrellis Biosystems, Inc.. Completed at 1 site in United States. Open to female participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-07-16.

The goal of this study is to observe the healing of skin after ellacor® treatment at different timepoints, depths and coring densities. The visual comparison of treated areas to untreated control areas will improve understanding of how the ellacor® procedure works to induce skin resurfacing 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:
How does human skin change after a series of the ellacor® procedures over a 14-day period?
Is the ellacor® device safe to use at different treatment time points, depths and densities?
The ellacor® procedure will be performed on people who are going to have abdominoplasty surgery. The ellacor® treatment areas will be limited to the skin areas marked for removal 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 the study.
The 3 participants will have the ellacor® procedure done at 4 different timepoints before their abdominoplasty surgery: -14 days, -7 days, -3 days and on day 0, just prior to the abdominoplasty procedure. At each treatment timepoint the participants will have 3 areas treated using a depth of 7mm and different skin removal percent settings of 5%, 7% and 8%. The participants will have photos taken of the treatment areas and will be asked about any changes to their health or medications over the 14-day 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, which is the control area. This will reveal, by visual comparison, any changes in the skin tissue between treated and untreated areas, if they occur.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Three participants will have the ellacor® procedure done at 4 different timepoints before their abdominoplasty surgery: -14 days, -7 days, -3 days and on day 0, just prior to the abdominoplasty procedure.

Device: ellacor® Micro-Coring procedure
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.
Incidence and severity of adverse events
The incidence and severity of adverse events will be evaluated for all subjects enrolled to the study.
Time frame: Adverse events will be collected from Day 0 (the initial ellacor treatment day) through the day of the scheduled abdominoplasty procedure (Day 14 for all subjects).
The change in histopathology of abdominoplasty tissue samples after sequential treatments with the ellacor® device at a micro-coring depth of 7mm over a 14-day period as compared to an untreated control area.
This 14-day healing evaluation of fractional skin resurfacing will compare the histopathology of stained tissue isolated after sequential ellacor® treatments on abdominal skin tissue. The samples will be isolated from excised abdominal tissue following abdominoplasty. The tissue will include an untreated control area compared to three ellacor® treated areas with depth of treatment at 7mm and different tissue percentage removal settings. Area 1 = 5% tissue removal, Area 2 = 7% and Area 3 = 8%. Each area will be treated on Day -14, Day -7, Day -3 and Day 0, the day of abdominoplasty. Histopathological evaluation will include Hematoxylin and Eosin (H\&E), Herovici, and Movat stains. The stains will provide comparison of structural tissue changes (H\&E stain), change in presence of Type III (young) collagen and Type I (mature) collagen (Herovici stain) and change in presence of collagen, fibrin and elastic fibers (Movat stain) over the 14-day time period compared to untreated control area.
Time frame: The abdominoplasty tissue will be excised 14 days after the initial ellacor® treatment. Histopathological studies will be performed upon receipt at the central pathology laboratory.
