Prosthetic interface

A prosthetic interface comprising:

• a body portion including a proximal end having an open configuration, and a distal end having a closed configuration, the body portion formed by a membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface, the internal flow space arranged to transport fluid through the membrane component and relative to the skin surface, the body portion including an elastomeric wall portion and the membrane component is positioned radially inside of the wall portion along an inner side of the elastomeric wall portion;
• and
• a textile cover extends along an outer side of the elastomeric wall portion;
• a distal cup formed of a polymeric material at the distal end of the body portion;
• at least one material coating selectively applied to the membrane component such that the at least one material coating interacts with at least one of the membrane component and the distal cup to define a breathable region, and an impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket;
• wherein the membrane component defines an inner side and an outer side, the at least one material coating extending along the outer side of the membrane component;
• wherein the at least one material coating is formed from an elastomeric material.
