Abstract: Medical articles comprising a conformable wound dressing and delivery system. The wound dressing generally comprises a backing having a first major surface and a second major surface, an adhesive on the second major surface of the backing, and an absorbent pad proximate the second major surface of the backing. The backing extends beyond the perimeter of the absorbent pad, typically beyond the entire perimeter of the pad. The perimeter of the wound dressing has a concave feature that exhibits a local minimum. An axis extends from the local minimum to the perimeter of the wound dressing opposite the local minimum. The carrier overlies at least a portion of the backing on each side of the axis but does not overlie the backing along the axis. The wound dressing is especially designed for use on round or irregular shaped body parts, such as an elbow or heel.

Abstract: A viscoelastic wound closure dressing. The dressing can include a viscoelastic backing having a first major surface configured to face skin when in use, a first end, a second end, and a middle section located between the first end and the second end. The wound closure dressing can further include a skin-contact adhesive on the first major surface of the viscoelastic backing adjacent the first end and the second end. A majority of the first major surface of the middle section can be free of the skin-contact adhesive. The viscoelastic backing can recover, at room temperature: (i) no more than 40% of its deformation after 10 seconds, after being strained to 50% elongation for 30 minutes, and (ii) at least 70% of its deformation after 48 hours, after being strained to 50% elongation for 30 minutes.
