hollow 1206 defined between two sides 1216 and 1218 of split tube 1212 in fig1 c tube 1212 is retracted relative to tube 1214 while pressing the whole remover forward thus the effect is that of advancing tube 1214 over tube 1212 in an exemplary embodiment of the invention tube 1212 includes one or more protrusions 1220 at its distal end that increase its diameter tube 1212 has an increasing outer diameter at its distal end and or outer tube 1214 has a narrowing inner diameter thus when tube 1214 reaches base 1210 or possibly before that time spike 1208 is gripped by inner tube 1212 continued retraction of inner tube 1212 for example as shown in fig1 d pulls spike 1208 through base ring portion 1210 in an embodiment where base ring 1210 includes a spring tab e g 718 fig7 a to prevent retraction of spike 1208 under normal conditions inner tube 1212 and or outer tube 1214 are optionally designed to allow freedom of motion for the tab spike 1208 is optionally straightened by the retraction through base ring 1210 alternatively or additionally to friction engaging of the spike in some embodiments of the invention protrusions 1220 engage a tab portion or an aperture formed in the spike in another embodiment of the invention a remover 1200 is adapted to remove a plurality or even all the spikes of a connector at one time in this case inner tube 1212 is optionally made of sufficient diameter to enclose the graft and the spikes are engaged between the inner tube and the outer tube a separate further outer tube relative to which the two other tubes are retracted and which provides a contra against the base ring may be provided thus in some embodiments.
