A gun that heals?

A gun that heals?

This revolutionary skin-cell spray gun drastically cuts healing time for burns by using the patient’s own stem cells.

Patients have healed in days rather than months

For patients suffering severe burns and other wounds, the prospect of a quick-healing, gentle spray containing their own stem cells will be a promising alternative to conventional skin graft surgery, which can be painful, prone to complications, and slow-to-heal.

Patients can be treated within 90 minutes of arriving in an emergency room

Makers of the device, RenovaCare, say of their SkinGun spray that it is the world’s most advanced technology of its kind, using a gentle positive-pressure air stream to spray a solution of the patient’s own stem cells onto wounds. This is a marked improvement over pump spray devices, which spray by creating high pressure behind a narrow aperture, and expose fragile cells to strong forces that are likely to tear them apart.

Two-phase system is improvemnt on current technology, say makers

The company website had this to say of the technology –

RenovaCare’s CellMist™ System is comprised of two components: 

  • CellMist™ Solution – A liquid suspension of the patient’s own stem cells.
  • SkinGun™ An ultra-gentle spray device which delicately deposits the CellMist™ Solution on to a patient’s wounds.

What is the CellMist Solution?

 The CellMist Solution is a liquid suspension containing a patient’s own regenerative skin stem cells. A small sample (as little as a square inch) of the patient’s skin is quickly processed to liberate the stem cells from surrounding tissue. The resulting product is referred to as the ‘CellMist™ Solution’. The CellMist™ Solution is placed in the SkinGun™ for spray application onto the patient’s wound. 

What is the SkinGun? 

The CellMist Solution, containing the patient’s stem cells, is transferred to the SkinGun™. The SkinGun™ sprays the cells onto wound sites to begin healing. Unlike conventional aerosol and pump systems, our next-generation fluid sprayer does not expose fragile cells to strong forces that can tear them apart. Instead our SkinGun™ gently delivers the CellMist™ Solution directly to the wound site using a positive-pressure air stream. 

Note: RenovaCare products remain under development and are not yet FDA approved for sale in the United States.

Similar skin-spraying technique substantially cut the death toll in the Bali bombings in 2002

Skin spraying have been in use for some time elsewhere, such as in Australia, where Dr Fiona Wood of the West Australia Burns Unit developed a method called “spray-on-skin.” Dr Wood’s method uses an aerosol system to spray on cultured skin cells. This system also cuts healing time to days rather than weeks or months, and the technique substantially cut the death toll in the Bali bombings in 2002.

The depth of a burn determines its severity. First degree burns damage the outer layer of skin (epidermis) and cause pain, redness and swelling (erythema). Second degree burns damage the epidermis and the inner layer, the dermis, causing erythema and blistering. Damage from third degree burns extend into the hypodermis, causing destruction of the full thickness of skin with its nerve supply (numbness). Third degree burns leave scars and may cause loss of function and/or sensation.
