1. A system for securing body tissue, comprising:
- an elongate member, wherein the elongate member is configured to secure at least one of a tissue, bone, and implant; and
a medical device configured to tension the elongate member, the medical device comprised of;
a handle;
an outer tube, fixed in position relative to the handle, including first and second ends and defining a longitudinal passage along a central longitudinal axis, wherein the second end of the outer tube is disposed in the handle, and wherein the elongate member is configured to enter the first end of the longitudinal passage of the outer tube, and pass at least partially through the longitudinal passage in the outer tube; and
a tensioning mechanism disposed on the handle of the medical device, the tensioning mechanism comprising;
a rotation assembly;
at least one biasing member configured to apply a tension force to the elongate member; and
a rotatable shaft positioned along an axis perpendicular to and intersecting the axis defined by the longitudinal passage of the outer tube, the rotatable shaft having an open end slotted aperture through which the elongate member is configured to be captured and secured,wherein rotational actuation of the rotation assembly of the tensioning mechanism applies tension to the elongate member as the rotation assembly wraps the elongate member around the rotatable shaft.

Abstract
A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. A medical device is used to secure the fastener to the elongate fastening member. The medical device includes a tensioning mechanism for tensioning the elongate fastening member. As crimping mechanism is used to secure the fastener to the elongated member, where a cutting mechanism cut the excess portion of the elongated member.
