The disrupter (16) includes an elongated hollow barrel (18) having a cylindrical inner chamber (20), a closed rear (26) end and an opened front end (22), the latter closed with a front frangible seal (38). A channel member (46) partly surrounds an intermediate portion of the barrel, and is securely attached thereto. A pair of recoil channels (76, 78) extend from the barrel inner chamber, radially outwardly and rearwardly through the barrel and the channel member, and are linked to rearwardly oriented recoil tubes (52, 54) which have opened rear end portions (60, 62) closed with rear frangible seals (64, 66). In use, a cartridge (90) including an explosive charge (88) is to be inserted in the barrel inner chamber at its rear end, and the barrel, recoil channels and recoil tubes (52, 54) are to be filled with water. The frangible seals (38, 64, 66) prevent the water from leaking out of the disrupter while it is positioned near a bomb to be deactivated. A trigger (36) is linked to the disrupter, and more particularly to the cartridge, to remotely detonate the explosive charge. Upon the explosive charge being detonated, a portion of the water is propelled and ejected at high velocity out through the barrel front end, rupturing the front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components. Another portion of the water is redirected through the side recoil channels and recoil tubes, rupturing the rear frangible seals, to be ejected rearwardly out of the disrupter. The recoil created by the detonation of the explosive charge which ejects the water through the barrel front end, is at least partially counteracted by the water being laterally and rearwardly redirected to be ejected rearwardly out through the recoil tubes. The recoil tubes have at their rear ends (60, 62) transverse blades (73, 74) for wide angle dispersal of the fluid jet being ejected rearwardly.

The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

The invention provides a monoclonal antibody, a fragment thereof, or a molecular complex thereof that binds to an extracellular domain of an EphA2 receptor molecule, wherein binding of the monoclonal antibody or fragment thereof to the EphA2 receptor molecule present in the membrane of a cancer cell favorably alters activity of the EphA2 receptor molecule. The invention further relates to methods of making and using the monoclonal antibodies, fragments, and molecular complexes regarding the same. The monoclonal antibodies of the present invention target the extracellular domain of EphA2 and operate to redirect the function of EphA2 to selectively block the growth and invasiveness of metastatic cells. The invention thus makes possible therapeutic strategies that optimally target metastatic cells while preventing collateral damage to normal tissues.

An ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.

A specialized tool is provided for the removal of components in a microwave module in which a fixed tool having a channeled tip is positioned adjacent the component to be removed. A hot stream of gas, in one embodiment nitrogen, is then forced through the channel onto the top surface of the component to be removed, with the microwave module lying on a heated platen, such that the local increase in temperature at the component to be removed is enough hotter than the ambient temperature of the module as determined by the heated platen to soften the silver epoxy used to mount the component to the module without damaging nearby components. With the fixed tool adjacent the component to be removed and with the component provided with targeted heating, the module is moved against the tool to cause a shear force that moves the component away from its original position, thus breaking the epoxy bond, after which the component is plucked from the module. The subject tool and technique eliminates collateral damage associated with the use of a ball peen hammer and chisel, and results in a tenfold decrease in rework time.

A method for HIFU treatment of localized prostate cancer in a patient includes identifying the cancer locations in a patient's prostate; visually segmenting the patient's prostate into areas for analysis and treatment, where the section including the area of most aggressive cancer is determined to be the primary area. The primary area is subjected to a first full HIFU treatment for a period intended to ablate the cancerous tumor. HIFU treatment is then stopped on the primary area and the primary area is allowed to rest while simultaneously subjecting the next contiguous area of the patient's prostate to a first HIFU treatment to ablate any additional areas of suspected cancer in the next contiguous area. HIFU treatment is then stopped in the contiguous area. The primary area is then subjected to a second full HIFU treatment for a period sufficient to ensure the complete ablation of the cancerous tumor. The method further includes repeating alternating full HIFU treatment processes on subsequent contiguous areas of the patient's prostate to ensure the complete ablation of any cancerous tumors in the patient's prostate. The entire process is completed under one treatment of anesthesia.
