1. A minimally invasive medical fastening device comprising:
- a housing;
a plurality of springs disposed in the housing;
a plurality of staples;
a shutter disposed in the housing between the plurality of springs and the plurality of staples; and
an anvil member;
wherein the shutter is movable sequentially from a first position in which the shutter holds all of the plurality of springs in a compressed condition, to a second position in which the movement of the shutter releases a first spring of said plurality of springs, causing a first staple of said plurality of staples to deploy, to an nth position in which the movement of the shutter has released all of the plurality of springs, causing all of said plurality of staples to deploy.
