Abstract: A filter system comprises an expandable filter, with a first end of the filter attached to an end of a first tube, and a second end of the filter attached to an end of a second tube. The tubes are arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move between a first collapsed, position and a second expanded position, where the filter extends outwardly. The filter may be a folded-over member, when in the expanded position, or a spiraling member.

Abstract: Provided is an implantable sling for supporting a body organ. The sling may be used, for example, as a urethral sling, a puborectal sling or a surgical mesh for pelvic organ prolapsed repair. The sling of the invention has a first sling element, having a first sling body and two or more slender first projections extending from the first sling body. The sling may further include a second sling element having a second sling body and two or more slender second projections extending from the second sling body, and one or more detachable connections connecting the first sling element and the second sling element. In some embodiments, the connections are configured to tear when the first and second sling elements are pulled apart.

Abstract: A set of two saw benching rolls. Each roll has a surface divided into two sections. One section is in the form of a convex surface and the other is in the form of a concave surface. The rolls are mounted in an opposed relationship and are operable to apply pressure to a saw placed there between. By moving the two rolls axially and relative to one another in the various positions, the saw may be "leveled up" or "leveled down" to remove discontinuities. The benching rolls may also be used in the conventional manner to tension or to shear the saw.
