Flex cable and spring-loaded tube for tacking device

A surgical fastener applier, comprising:

• a handle portion;
• a tubular member extending from the handle portion and defining a longitudinal axis;
• a stiffener member having a different rigidity than the tubular member;
• a coiled spring disposed within the tubular member and being configured to maintain a substantially straight condition of the tubular member;
• a drive member rotatably supported in the tubular member and in the handle portion, the drive member including a central portion being radially flexible and torsionally stiff;
• and
• a plurality of fasteners disposed within the tubular member and each fastener being configured to engage a portion of the drive member such that rotational motion of the drive member causes distal advancement of at least one fastener of the plurality of fasteners through the tubular member, at least one fastener of the plurality of fasteners engaged with the coiled spring;
• wherein a clearance is defined between the drive member and the tubular member, and the drive member is configured for rotation in a deflected condition.
