Cannula

A cannula adapted to receive an implant object into its interior at the proximal end, the cannula being attachable to an implantation device having a push-rod which enters the cannula at its proximal end, an operator utilizing the implantation device to make an incision in a body with the cutting edge of a bevel at the distal end of the cannula, the operator completing the implantation process by pushing on the push-bar thereby causing a force to be applied to the implant object resulting in the implant object moving from a position within the cannula out through the distal end and into the body, a structural impediment being incorporated in the bevel region of the cannula which prevents the implant object from falling out of the cannula at the distal end as a result of changes in cannula orientation prior to the execution of the implantation process, the structural impediment being automatically circumbented during the execution of the implantation process.
