Abstract
A medical article and methods of using same. The medical article can include a machine direction (MD) and a cross-machine direction (CMD); a support layer; and a viscoelastic layer. The viscoelastic layer can be coupled to the support layer, and the viscoelastic layer can be discontinuous in the MD and/or the CMD. The viscoelastic layer can recover at least 70% of its deformation after 48 hours at room temperature after being strained to 50% elongation, such that the medical article has a first tensile stiffness Tat a first strain rate S, and a second tensile stiffness Tat a second strain rate S. The ratio of S/Scan be at least 100, and the ratio of T/Tcan be at least 1.5. The method can include wrapping the medical article around a body part; applying the first strain rate S; and applying the second strain rate S.
