Claim 0:
1. A method of simultaneously driving a plurality of tissue screws to affix an apical cuff to heart tissue, comprising the steps of:
a. aligning the apical cuff to a desired position on a heart;
b. simultaneously driving the plurality of tissue screws through a sewing skirt on the apical cuff and into heart tissue by providing a synchronous multi-driver tool for affixing the apical cuff to a heart, the synchronous multi-driver tool having a drive input sub-system, a transfer sub-system, and a driver sub-system whereby rotational input at the drive input sub-system transfers rotational force to the transfer sub-system, which, in turn, transfers rotational force to the driver sub-system and drives a plurality of driver members each operably coupled to a tissue screw to apply rotational force to each tissue screw simultaneously without substantial axial force applied to each tissue screw;
c. axially compressing the apical cuff onto the heart tissue with the plurality of tissue screws; and
d. releasing the apical cuff joined to the heart tissue.
