The Spirit Hydrocolloid Sheath Male External Catheter is expanding the boundaries of continence care. This external sheath catheter from Rochester Medical uses the same hydrocolloid adhesive often found in wound care dressings to give you the best possible adhesion that still wicks moisture away from the skin. The moisture is transported away from the skin and into the silicone sheath where it will evaporate. This prevents skin-damaging moisture buildup to keep your skin as healthy as possible.
