Prosthetic Attachment System Vacuum Mechanical Suspension Patent Application
Summary
USPTO published patent application US20260108369A1 (application no. 19363285, filed 2025-10-20) for a prosthetic attachment system combining vacuum suspension and mechanical suspension. The system includes an attachment pin extending from a prosthetic liner, a connector assembly securing to a prosthetic socket, and a lanyard assembly with an external securing system. CPC classifications include A61F 2/7812 (prosthetic socket vacuum or weight-bearing chamber), A61F 2/60, A61F 2/80, and A61F 2002/7875. Five inventors are listed: Hafsteinn JONASSON, Sigurdur HANNESSON, Oskar Thor LARUSSON, Margret Sol RAGNARSDOTTIR, and Halldor ALBERTSSON.
“A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension.”

What changed
USPTO published patent application US20260108369A1 for a prosthetic attachment system and corresponding lock assembly. The system connects a distal end of a prosthetic liner to a distal end of a prosthetic socket using combined vacuum suspension and mechanical suspension. Key components include an attachment pin extending from the prosthetic liner, a connector assembly adapted for receiving and locking to the attachment pin, and a lanyard assembly with external securing system. The application covers five inventors and specifies CPC classifications in the A61F prosthetic domain.
For manufacturers of prosthetic components, this patent application indicates competitive activity in dual-suspension technology for prosthetic limbs. Medical device manufacturers and prosthetics companies should review their product development pipelines to assess potential overlap with the claimed vacuum-mechanical combination technology. This is a published application only — it does not yet grant enforceable patent rights.

Abstract
A prosthetic attachment system and corresponding lock assembly are provided for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket, by combining vacuum suspension and mechanical suspension. An attachment pin extends from a distal end of the prosthetic liner. A connector assembly secures to a distal end of the prosthetic socket and is adapted for receiving and locking to the attachment pin. A lanyard assembly has a first end secured to the connector assembly and a second end extending outwardly from the distal end of the prosthetic socket and adapted to secure to an exterior surface of the prosthetic socket by an external securing system.
