Mar-Med’s Derma-Stent™:

Derma-Stent is a new, minimally invasive cutaneous drain preferred over packing gauze by clinicians and patients alike in a recent trial. Clinicians are moving away from the use of gauze for incision and drainage because it’s painful, can cause toxic shock and often requires multiple visits for evaluation and management. Derma-Stent provides the ease and comfort of the “loop drain” method, but the unique design can be customized for use in 1 or 2 incisions, without tying clumsy knots or sutures.


Derma-Stent Clinical Trial Complete!

A randomized, controlled clinical trial ( Identifier: NCT03171714) comparing standard packing gauze to using Derma-Stent for abscess treatment was completed at Wayne State University under Aaron Brody, MD, MPH.  While the final manuscript on the trial is being written, The Journal of Emergency Medicine has published Dr. Brody’s description of using Derma-Stent on the trial’s first enrollee.

1) Drain the site using 1 or 2 incisions.

2) Measure the site along the Derma-Stent™. Cut to appropriate size.

3) Insert Derma-Stent™ into cavity.

4) Remove Derma-Stent™ in accordance with clinician instructions.

Derma-Stent™ Added Value

An estimated 4.5 million incision & drainage procedures are performed on abscesses in the USA each year in outpatient and acute care.  For years wound packing has been thought to keep abscess walls separated and allow drainage by preventing premature closure.  But it is extremely painful (especially for children), often requires follow up and still has a relatively high failure rate.  A new less invasive method is performed by tying a “loop drain” through two small incisions and meta-analysis of literature already suggests this method provides lower failure rates (4.10% vs 9.43%), potential for less pain, decreased scarring, and lower healthcare utilization costs.  A similar technique involving a Jacobi ring has been demonstrated to compare well against the Word catheter used on Bartholin cysts.

Our Solution

Mar-Med’s Derma-Stent was designed with the benefits of the minimally invasive method in mind, but simpler.  A clinical trial has recently demonstrated the comfort and efficacy of the device.  Whether for abscess or cysts, in pediatrics or adult patients, Derma-Stent may be considered to replace packing gauze, loop drains and Word catheters, while saving cost and improving care.

Loop Drainage Is Noninferior to Traditional Incision and Drainage of Cutaneous Abscesses in the Emergency Department, Elissa M. Schechter‐Perkins MD, MPH Kristin H. Dwyer MD, MPH Anish Amin MD Matthew D. Tyler MD James Liu MS Kerrie P. Nelson PhD Patricia M. Mitchell RN.

  • Summary: The study provides evidence that LD is noninferior to I&D in achieving complete abscess resolution at 14 days and is associated with fewer return ED visits and fewer complications. This makes it an attractive alternative treatment option for abscesses.

Comparison of the loop technique with incision and drainage for soft tissue abscesses: A systematic review and meta-analysis; Gottlieb M, et al.

  • Summary: This systematic review identified four studies comprising 470 total patients. Overall, the CID technique failed in 25 of 265 cases (9.43%). The LDT failed in 8 of 195 cases (4.10%)

  • Summary: LDT…saves operating theatre time with 30% of LDT treated in the Emergency Department and ensures excellent follow-up compliance as patients return for VessiLoop removal. Healthcare burden is greatly reduced using LDT; most patients require only one review at 10-14 days.

Treatment of subcutaneous abscesses in children with incision and loop drainage: A simplified method of care; Aprahamian CJ, et al, Journal of Pediatric Surgery.  Sep;52(9):1438-1441.

  • Summary:  The findings eliminate the need for repetitive wound packing and simplify postoperative wound care. Loop drainage offers shorter time to discharge, lower recurrence rates, and minimal scarring. Additionally, there is expected cost reduction.

Jacobi ring catheter treatment of Bartholin’s abscesses; Gennis P, et al. American Journal of Emergency Medicine. (May 2005) Volume 23, Issue 3, Pages 414–415.

  • Summary: “Ease of insertion was similar for the 2 devices. Patient satisfaction was higher in patients treated with the ring catheter.”


“The patients report no significant discomfort from the placement or removal. Some say they didn’t even realize it’s there. Much better than packing and re-packing wounds!”
