In many processes used in fabricating semiconductors the wafer is seated on the top surface of a pedestal and heated in a high energy process step, such as plasma etching. The pedestal, chuck or platen may be cooling but the wafer gradually heats until the process can no longer continue. Where large, e.g. 300 mm diameter, wafers are being processed the temperature level across the wafer is difficult to maintain substantially constant. In this system and method the lateral temperature distribution is equalized by a heat sink structure in a chamber immediately under the wafer support on top of the pedestal. A number of spatially distributed wicking posts extend downwardly from a layer of wicking material across the top of the chamber, into a pool of a vaporizable liquid. At hot spots, vaporized liquid is generated and transported to adjacent condensation posts extending up from the liquid. The system thus passively extracts heat to equalize temperatures while recirculating liquid and assuring adequate supply. The free volume above and within the liquid, and the short distances between posts, assure adequate heat transfer rates.

An improved, easy opening, screw-cap for threaded opening type containers is disclosed, consisting of a plastic or metal cap of generally cylindrical shape. Located along the upper section of the cap's outer circumferential surface are three, equally spaced, grasping protrusions, that extend radially outward from the radial center of the cap, so as to form a cap of a generally rounded, triangular configuration as seen from above. These grasping protrusions provide torsional, mechanical interference for the hand and it applies rotational force to screw on or off the cap. A series of vertically extending, gripping ribs, are equally spaced along the outer circumferential surface of the upper section of the cap, and are designed to make it easier to screw the cap on and off the neck of a conventional container, such as a bottle. Conventional internal screw threads are used on the internal cavity of the cap to attach the cap to the neck of a conventional container, such as a bottle.

A graft ligament is looped through a graft hole in a graft ligament support block, and the graft ligament support block is mounted to an installation tool. Then the installation tool is used to advance the graft ligament support block into a bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with a transverse fixation pin hole in the graft ligament support block. Then the graft ligament support block is secured in place by pinning the graft ligament support block within the tunnel, i.e., by advancing a transverse fixation pin along the transverse tunnel and into the transverse fixation pin hole in the graft ligament support block. Then the installation tool is detached from the graft ligament support block and withdrawn from the surgical site.

A method for removing thrombus or other material from a natural or synthetic body vessel or cavity without the need for direct surgical access. The method includes providing a device supplying high pressure fluid to at least one distal orifice, causing high pressure fluid to emanate from the orifice creating at least one fluid jet, and using the fluid jet to break up material in the vessel. The method further includes directing at least one fluid jet at the opening of an exhaust lumen or target incorporated into the device and using the jet to provide a localized negative pressure which entrains material into the jet for break-up. The method optionally includes using the jet to provide stagnation pressure which drives material along the exhaust lumen. The method optionally includes metering the exhaust to match the fluid input or to be greater or less than the input. A positive displacement pump operating at steady or pulsatile flow provides the high pressure saline to the distal end of the catheter.

A device for removing a thrombus or other tissue deposit from the cardiovascular system, natural or synthetic tubule or cavity found in the human body of a patient without the need to surgically access the location of the thrombus or other tissue deposit via a cut-down or other surgical procedure. A flexible metal or high pressure plastic tube conveys an extremely high pressure stream of sterile saline or other physiologic solution to at least one jet at the distal end of the catheter. At least one jet is directed at the opening of a large exhaust lumen or other target. The jet(s) is responsible for providing a localized negative pressure which entrains tissue into the jet from break-up of the debris. This jet(s) can also provide stagnation pressure in the exhaust lumen which drives the tissue or thrombotic debris out of the exhaust lumen. Operation of the device with tip pressure greater than 500 psi provides this device with the entrainment and exhaust characteristics which contribute to its effectiveness. The rate of exhaust of tissue debris is metered to ensure minimal local impact on the vasculature at the site of the thrombus deposit. A fluid metering means, such as a roller pump, controls the rate of exhaust such that it is in balance with the saline input or can be adjusted to be greater or less than the input. A positive displacement pump operating at steady or pulsatile flow provides the high pressure saline to the tip of the catheter.
