A tool assembly designed to couple to a torsion spring and torsion rod to wind and unwind the torsion spring on the torsion rod. The tool assembly includes a variety of components in mechanical communication with one other to rotate the torsion spring. Specifically, the assembly includes a worm gear in mechanical communication with a ring gear and a set of brackets securable to a torsion spring. Between the ring gear and the brackets are a series of plates arranged and assembled on a base, providing a singular device within the assembly that a user can grip to manipulate a torsion spring in a safer manner than possible in the prior art. A drill or other device can couple to attachment points in mechanical communication with the worm gear to rotate the worm gear at a greater rate, thereby reducing the winding and unwinding time of the torsion spring.

A biomaterial collection device can include a wire that includes a functional member including a proximal end, a distal end, a first flat surface and a second flat surface opposing the first surface. The functional member can be configured to fit within a body lumen. The functional member can include binding elements configured to bind circulating biomolecules and cells. The functional member can include curved portions that form revolutions around the longitudinal axis of the device.

Disclosed is a system for automating and optimizing coil formation in a wire rod cooling conveyor comprising: (a) a speed measuring device (e.g., a laser velocometer) measuring a speed of a material entering a laying head; (b) a processor that: (1) receives, as input, the speed measured in (a), (2) computes an optimal speed of the laying head based on the received speed of the material entering the laying head; and wherein the processor dynamically computes the optimal speed of the laying head as the speed of the material changes. Also disclosed is a camera that monitors actual ring formation on the wire rod cooling conveyor at an exit point of the laying head, wherein the processor receives such monitored information from the camera and outputs a control signal to override the speed measuring device and to adjust a speed of the wire rod cooling conveyor.
