Abstract
The invention concerns monolithic foam sleeves that comprises titanium or titanium alloy foam having a porosity of 50 to 85% and possess a proximal end, a distal end, an interior wall that defines an interior channel and extends from the proximal end to the distal end; and a terraced outer surface that tapers such that said sleeve is widest at the distal end and most narrow at the proximal end.
