An embodiment of the present invention may be made by the following steps: providing a mixture comprising a plurality of fibers, a lubricant, and a suspension fluid, with the suspension fluid filling a void space between said fibers and subjecting said mixture to at least one compressive force. The compressive force causes the migration and alignment of said fibers; and may remove substantially all of the suspension fluid from said mixture. The mixture may further comprise a biologically active agent, or a reinforcing agent.

An interventional catheter assembly comprises an operating head for removing obstructive material from a target site in a body lumen or cavity and at least one aspiration port located proximal to the operating head and penetrating the catheter assembly, the aspiration port being in communication with a sealed lumen that communicates with a vacuum system for withdrawing aspirate fluid and obstructive material from the target site. A rotatable member is positioned inside the catheter assembly at the site of the aspiration port and rotates during operation of the vacuum system. The rotatable member is provided with at least one upstanding bar that is sized to cooperate with the walls of the aspiration port and the inner surface of the catheter assembly to macerate debris that is drawn into the aspiration port.

A method of harvesting crop material includes gathering the crop material and separating chaff material, and subjecting the chaff material to fragmentation in a cage mill to destroy unwanted seed material contained therein. Also provided is a mobile agricultural apparatus which travels with a harvesting machine during a harvesting operation to receive chaff material produced during the harvesting operation. At least one cage mill having rotors for fragmentation of the chaff material is included with the mobile apparatus, to destroy unwanted seed material contained therein. Such a cage mill includes at least a casing defining a milling zone, a rotor for performing milling, an inlet for introducing material for reduction into the milling zone, an outlet for removal of material from the milling zone, and an airflow through the milling zone to assist movement of the material through the milling zone from the inlet to the outlet.

The invented vehicle includes a chassis, a cabin mounted on a first side of the chassis on a forward portion thereof, and a plurality of wheels coupled to the chassis to movably support the chassis. The vehicle also includes a boom unit, a tool coupled to an end of the boom unit, and turntable unit mounted to the chassis at a central portion thereof, the turntable unit coupled to and supporting the boom unit for rotation relative to the chassis. The turntable unit is capable of moving the boom unit and the tool over a second side of the chassis opposite the first side between a first position at which the tool is positioned forward of the chassis to pick up the load and a second position at which the tool is positioned over the dump body to dump the load into the dump body. The vehicle also includes a dump body mounted to a rear portion of the chassis. The dump body can be tilted to the rear or either side of the vehicle. The tool attached to the boom unit can be a dipper bucket, a loader bucket, a mower, thresher or auger, for example. An accessory tool such as a mower can also be attached to the rear of the vehicle.

A rake retractor for use in minimally invasive medical procedures such as laparoscopic surgery includes a handle shaft, rake prongs, and end configurations that can be used to move elements within a body cavity. The prongs of the rake retractor are biased to an open position such that when the rake prongs extend out of the needle they open, and they are closed by relative movement of the needle over them. The end configurations are offset so that they may be compactly brought together within the narrow space of a needle having a diameter typically not greater than 2.5 mm.
