Apparatus for securing an object to bone, the apparatus comprising:

• • a suture anchor assembly comprising a suture anchor body and a suture;
    • the suture anchor body being configured to be lockingly disposed within a hole formed in the bone, and having an opening formed therein for slidably receiving the suture therethrough;
    • the suture having a first end, a second end and an intermediate portion extending therebetween;
    • the suture extending through the opening in the suture anchor body so that the intermediate portion forms a loop on one side of the opening and the first and second ends are disposed on the other side of the opening, such that when the first end of the suture is passed through the loop and securingly engages the object, pulling on the second end of the suture draws the loop and a captured portion of the suture along a path toward the opening in the suture anchor body;
    • the suture anchor body being configured so that when the suture anchor body is disposed in the hole in the bone, a tapered binding zone is established along the path followed by the loop and the captured portion of the suture when the second end of the suture is pulled, the tapered binding zone having a successively decreasing cross-sectional area such that continued pulling of the second end of the suture causes the loop and the captured portion of the suture to be jammed tightly in the tapered binding zone, whereby to bind the suture, and hence the object, to the suture anchor body, which is itself lockingly disposed within the bone.

A method and apparatus are provided, for forming a filter element including a media pack in the form of a coiled web of fluted filter media, by feeding the web of fluted filter media at a controlled linear speed onto a mandrel rotated by a winding motor providing a controlled driving torque to the mandrel, to thereby maintain a controlled tension on the web of fluted filter media as the web is wound onto the mandrel. The web may be fed at a substantially constant linear speed to the mandrel, and/or the winding motor may be controlled in a manner providing substantially constant driving torque to the mandrel for maintaining a constant tension on the web as a function of the constant driving torque. Coiled media packs having circular or non-circular cross sections, can be formed with either cored, or core-less construction.

A surgical instrument may be used to apply tension to a flexible suture to close and secure a broken or cut bone (e.g. a sternum following a sternotomy). The device preferably applies an adjustable tension to the flexible suture in order to secure the bone together. Multiple instruments may be used together to ensure the desired tension is applied to the entire bone structure being secured with the flexible sutures. Once the desired tension is achieved, the device preferably provides a mechanism to apply a uniform twist to the flexible suture to lock the flexible suture in place. The instrument preferably decreases the upward tension applied to the flexible sutures over the duration of the application of twisting.. The device may automatically cut the flexible suture, or the flexible suture may be cut by the surgeon once the twisting action has been performed.
