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.
