Mölnlycke Health Care acquires innovative wound therapy treatment
Mölnlycke Health Care announces that it has acquired a pioneering electrical stimulation technology that helps to accelerate wound healing. The product currently marketed under the name of woundEL® has been purchased from Gerromed GmbH and is in an early phase of commercialization.
Mölnlycke Health Care’s acquisition will significantly accelerate the company’s entry into this novel treatment area for hard to heal wounds. Non-healing wounds can be very expensive to treat, placing a burden on healthcare systems world-wide. Electrical stimulation has been shown to accelerate several aspects of the wound healing process.

Non-healing wounds can be very expensive to treat, placing a burden on healthcare systems world-wide. Electrical stimulation has been shown to accelerate several aspects of the wound healing process. Mölnlycke Health Care’s acquisition will significantly accelerate our entry into this novel treatment area for hard to heal wounds.
The therapy/product we have acquired is currently marked under the name woundEL® and is a highly effective combination of moist wound treatment and application of controlled, low frequency DC impulses. woundEL-therapy was developed for the treatment of acute, subacute and chronic wounds. Our intention is to further work with the development of the product, the clinical evidence and reimbursement.
The woundEL-therapy system consists of a therapy device with dressing electrodes and a dispersing electrode. The therapy device generates adjustable low frequency DC impulses which are applied through the sterile dressing electrode to the wound and are collected to the dispersing electrode. The contact to the wounds of the sterile dressing electrode is a medical grade hydrogel layer which not only provides the required moist environment for healing but also absorbs excess wound liquid.
woundEL-therapy can support the healing of patients with the following indications:
- Chronic leg ulcers
- Decubitus pressure ulcers (grades 2 to 4)
- Wounds caused by diabetes mellitus (diabetic foot ulcers)
- Before and after plastic surgical interventions (wound bed preparation)
- Suture deshiscence
- Acute wounds (e.g. burns, abrasions)
- Chronic wounds, which are resistant to traditional therapy
The treatment in practice
The treatment regime requires the patient to take a 30 minute stimulation twice per day. The active electrode is left in place similar to a normal moist wound dressing and needs to be changed around every second to third day depending on the exudate level. The dispersal electrode is applied via self-adhesive to a part of the body at least 30 cm from the active electrode before each treatment and removed after the treatment. A positive side-effect that is often commented by clinicians is the active engagement of the patient in their own treatment.
Electro-stimulation therapy such as woundEL is proven to be effective
The therapeutic effectiveness of electrical stimulation in wound healing has been documented worldwide for over 35 years in more than 500 professional publications. Due to published basic research and numerous randomised clinical studies as well as two metaanalyses (1,2), electro-therapy is classified - according to criteria of evidence based medicine - in Evidence Class Ia for clinical effectiveness.
Basic research has shown (3) that a physiological electrical field is one of the most important elements for the progress of wound healing.
- An electrical field together with normal sources of chemical gradients and a free wound edge enhance healing.
- An electrical field can override and dominate the healing influences of normal sources of chemical gradients and of a free wound edge.
There are currently three product areas; therapy device, dressing electrode and dispersing electrode.
