Title:
ARTIFICIAL JOINT COMPONENTS INCLUDING SYNOVIAL FLUID DEFLECTING STRUCTURES AND PARTICLE RETAINING STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2014/052150
Kind Code:
A3
Abstract:
Artificial joint prosthetic components including synovial fluid deflection structures are described. Embodiments of artificial joint prosthesis include those with: a bone-facing surface of an artificial joint prosthesis, the bone-facing surface configured to face a bone-prosthesis interface in vivo; a non-contact surface of the artificial joint prosthesis; and at least one fluid deflection structure positioned on the non-contact surface, the fluid deflection structure positioned to deflect synovial fluid away from the bone-prosthesis interface in vivo. Some embodiments include at least one particle retaining structure positioned to contact the directed flow of synovial fluid and configured to retain particles present within the synovial fluid.
