Prosthetic socket and socket liner with moisture management capability

A moisture management liner device for a prosthetic socket, configured to provide distal movement and radial escape of moisture from the prosthetic socket, the liner device comprising:

• an elongate, cup-shaped, elastomeric member, comprising an elastomeric material and extending from an open proximal end to a substantially closed distal end;
• a fluid exit aperture at the distal end of the elastomeric member, configured to allow fluid to pass out of the liner device;
• multiple longitudinally arranged fluid transport strips, comprising a wicking material and disposed at spaced-apart intervals around a circumference of an internal surface of the elastomeric member, over only a distal portion of the elastomeric member, wherein each of the longitudinally arranged fluid transport strips tapers from a large width at its proximal end to a narrow width at its distal end as the fluid transport strips converge centrally and terminate proximal the fluid exit aperture, and wherein the fluid transport strips are configured to facilitate passage of fluid out of the liner device through the fluid exit aperture;
• and
• multiple radially-directed pores disposed only on a distal-most region of a proximal portion of the elastomeric member, wherein the pores extend from the internal surface to an external surface of the elastomeric member, wherein the pores are arranged in lines around the circumference of the internal surface, and wherein a proximal-most region of the proximal portion of the elastomeric member has no pores, to facilitate forming an airtight seal between the proximal-most region and a residual limb.
