1. An appliance configured to contact tissue, comprising:
(a) a tissue interface portion comprising a viscoelastic foam configured to provide a tissue contact surface of the appliance, wherein the viscoelastic foam comprises each of the following properties:
a Shore 000 of between 1 and 40, as measured using the Standard Test Method for Rubber Property-Durometer Hardness ASTM D2240-15;
a density (specific gravity) of between about 0.2 to 0.7 g/cm3; and/or
a level of tack of between about 0.2 and about 9 mJ/cm2 as measured using the Standard Test Method for Pressure-Sensitive Tack of Adhesives ASTM D2979-16;
an elastic (storage) modulus of between about 1 kPa and about 15 kPa;
a viscous (loss) modulus of between about 0.8 kPa and about 7 kPa; and

(b) a non-contacting portion configured to support the tissue interface portion and to be separated from the tissue by the tissue interface portion.
