52. Apparatus for delivering a material or an implant into a bone, comprising:
-
(a) a delivery tube having a lumen and a distal end adapted for insertion into a body;
(b) a payload comprising at least one of material and an implant inside said lumen;
(c) a lining disposed between said tube and said payload; and
(d) an advancing mechanism adapted to move said liner and said payload to said distal end, wherein said liner reduces a friction of said payload against said delivery tube. - View Dependent Claims (53, 54, 55, 56)
