Abstract
An implant sleeve operable to center an implant at an implantation site. The implant sleeve includes a proximal end, a distal end, an annular sidewall, a mesh portion of the annular sidewall, and an interior area. The annular sidewall is between the proximal end and the distal end. The mesh portion defines a plurality of openings in the annular sidewall. The interior area is defined by the annular sidewall and is configured to receive a stem of the implant. A longitudinal axis of the implant sleeve extends along an axial center of the interior area. In response to force applied to the implant sleeve, the implant sleeve compresses and the mesh portion expands outward from the longitudinal axis.
