Device Story

Silverlon™ CA is a sterile, non-woven wound dressing composed of calcium alginate and a silver nylon contact layer.

The dressing absorbs wound exudate, maintains a moist wound environment, and allows for intact removal. It is intended for use on moderate to heavy exudating wounds. The device is applied topically by healthcare providers in clinical settings. It benefits patients by managing exudate and providing an antimicrobial barrier to support wound healing.

Clinical Evidence

Bench testing only. Three non-clinical studies were conducted: Systemic Injection Test in Mice, Cytotoxicity (Agar Diffusion), and Primary Dermal Irritation in Rabbits. No clinical data provided.

Technological Characteristics

Non-woven dressing composed of calcium alginate and silver nylon contact layer. Sterile, packaged in Tyvek pouches. Available in various sizes and rope form. Antimicrobial barrier provided by silver ion release. No software or electronic components.

Indications for Use

Indicated for patients with moderate to heavy exudating partial and full-thickness wounds, including pressure, venous, and diabetic ulcers, donor and graft sites, traumatic and surgical wounds, and 1st and 2nd degree burns. For external use only.
