Abstract
The sealing sheath is for use with a prosthetic socket and associated liner. The sealing sheath includes a textile tube for surrounding at least a portion of a liner that is configured to wear on a residual limb. An annular seal, e.g. an elastomeric or silicone seal, is positioned adjacent a proximal end of the textile tube and continuously extends from an inside of the textile tube configured to be adjacent the liner, through the textile tube to an outside thereof configured to be adjacent an inside of the prosthetic socket. The annular seal may include a first wing on an inside of the textile tube configured to be adjacent the liner, a second wing on an outside of the textile tube configured to be adjacent an inside of the prosthetic socket, and a base connecting lower ends of the first and second wings to define a v-shaped cross-section of the annular seal.
