DEFINITION

Classification: 602/43

Wound contact surface:

(under subclass 42) Subject matter wherein the wound covering device has particular physical surface features designed to improve the wound taction properties (e.g., healing rate, wound adherence, etc.).

(1) Note. This subclass contains skin laceration or wound covers which specify physical structural features or surface textural features which directly contact the wound (e.g., nonstick properties). Subclass 48 contains skin laceration or wound covers which have treatment material or composition in the wound contacting layer designed to promote healing of a wound. A patent which discloses a treatment material or

composition only and has no mention of surface textural features is properly classifiable in subclass 48. If both surface textural features and a treatment material are present, then the patent is properly originally classifiable in subclass 43 and a cross reference should be made in subclass 48.
