Methods and apparatus for sealing a puncture or incision formed percutane ously in tissue separating two internal portions of the body of a living bei ng with an anchor, a sealing plug and a filament connecting the anchor and s ealing plug are disclosed. The methods and apparatus provide for automatic t amping of the sealing plug. In addition, torque required to tamp the sealing plug is automatically sensed and gear ratios of an automatic tamping device are automatically changed in response to sensed changes in torque. A planet ary transmission may be used to automatically change gear ratios in response to the changes in torque. |
