Abstract
A prosthesis sleeve for attaching a prosthesis to a partially amputated limb of the body which is made of an elastomeric material which may have a tube shape and having concentric annular ribbing on an inside surface of one end to engage the remaining portion of the limb, thereby creating a suction-type seal therebetween to suspend the prosthesis. Another end of the sleeve has a smooth inside surface which engages the prosthesis forming a seal therebetween. The combination of seals creates an air tight junction and secure attachment of the prosthesis to the limb for rigorous activity such as athletics for persons requiring prostheses.
