An expandable intraluminal catheter is used for removing occlusive material from a body passage. The catheter includes a handle having both a proximal handle end and a distal handle end. Attached to the distal handle end is an elongate tubular body, which includes a proximal body end and a distal body end. The elongate tubular body further includes a lumen between the proximal body end and the distal body end. A number of expandable segments are disposed on the elongate tubular body near the distal body end. These expandable segments can be mechanically activated by a user when the distal body end is within a blood vessel, to thereby isolate and partition occlusive material within the blood vessel. The isolated and partitioned occlusive material within the blood vessel can then be removed.

A self-expanding medical occlusion device treats a heart defect in a patient and is inserted into the body in minimally invasive fashion using a catheter system, and includes a braiding of thin threads which exhibits a first preliminarily definable shape as the occlusion device is being inserted into the patient's body and a second preliminarily definable shape in the implanted state, whereby the occlusion device is in a collapsed state in the first shape of the braiding and in an expanded state in the second shape of the braiding. The threads of braiding are composed of a shape memory polymer composite such that braiding deforms from a temporary shape to a permanent shape in consequence of an external stimulus, whereby the temporary shape is given in a first profile form of the braiding and the permanent shape is given in a second profile form of the braiding.

A system for processing a simplified plastic container (C) that is to be filled with a hot product includes the step of blow-molding parison to form a container body, where the container body has a neck, a base, a side surface relatively free of structural geometry that surrounds an interior of the container body and, prior to being filled with the hot product, a projection (12) extending from the container body. After the container body is filled with a hot product in a production line, the neck of the filled container body is capped with a cap and then, the container body is cooled. During the cooling operation, the hot product is contracted so that the projection extending from the container can be pushed (P) into the container body like a traditional push-up so that the resultant, filled and cooled container body is relatively free of structural geometry.

In a semiconductor wafer including a plurality of imaginary-divided-regions which are partitioned by imaginary-dividing-lines that are respectively arranged in a grid-like arrangement on the semiconductor wafer and a circumferential line that is the outer periphery outline of the semiconductor wafer, a mask is placed so as to expose an entirety of surfaces of the wafer corresponding to respective removal-regions. The removal-regions are regions in approximately triangular form partitioned by the circumferential line of the wafer and the imaginary-dividing-lines. Then, plasma etching is performed on a mask placement-side surface of the wafer, by which the semiconductor wafer is divided into the individual semiconductor devices along dividing lines while portions corresponding to the removal-regions of the wafer are removed.

To provide a technology capable of improving reliability and manufacturing yield of a semiconductor device by reducing variations of electrical characteristics in connection hole portions. After a semiconductor wafer is placed over a wafer stage provided in a chamber for dry cleaning treatment of a deposition system, dry cleaning treatment is performed to a principal surface of the semiconductor wafer by supplying reducing gas, sequentially, heat treatment is performed to the semiconductor wafer at a first temperature of 100 to 150° C. by a showerhead which is maintained at 180° C. Next, after the semiconductor wafer is vacuum transferred from the chamber to a chamber for heat treatment, heat treatment is performed to the semiconductor wafer at a second temperature of 150 to 400° C. in the chamber, thereby removing a product remaining over the principal surface of the semiconductor wafer.

An instrument for precisely cutting tissue to controlled dimensions (length, width, depth, and shape) is provided for the removal of tissue specimens from remote sites in the body of a patient, such as from the gastrointestinal tract, urinary tract, or vascular structures, or any tissue surface or soft tissue of the body. The instrument has a housing and a substantially flexible shaft extending from the housing to a distal end. The distal end of the instrument has an open cavity into which tissue is receivable. Suction can be communicated along the shaft to the distal end for distribution across the cavity utilizing a manifold having a grated tissue engaging surface with opening(s) for applying the suction, thereby pulling tissue adjacent to the distal end into the cavity against the tissue engaging surface of the manifold. One or more hollow needles are extendable from the housing through the shaft into the cavity to enable infusion of fluid, such as saline or a hemostatic agent, into the tissue. A blade in the distal end is extendable through the cavity over the manifold and across the opening to cut the tissue held by suction and stabilized by the needles in the cavity. The shape and depth of the tissue removed by the cuts is in accordance with the contour of the tissue engaging surface and the size and shape of the cavity at the distal end. The tissue so removed by the instrument may be for therapeutic intervention and / or represent a tissue specimen for biopsy suitable of diagnostic evaluation. The tissue edges in the patient's body left after cutting with this instrument readily avail themselves to apposition for enhanced healing.

Expandable laser catheters for utilizing laser energy to remove obstructions from body passages are described. In one embodiment, the laser catheter includes a shaftway having a distal end including a flexible portion configured in a series of radial folds. Multiple optical fibers, configured to transmit laser energy, extend along the shaftway and are attached to the flexible portion. An inflatable, ring-shaped balloon is attached to the catheter within the flexible portion. In use, the catheter is inserted into a body passage such as an artery, and advanced until the distal end is adjacent to an obstruction. The balloon is inflated to expand the flexible portion and to bring the optical fibers nearer the inner wall of the body passage. Laser energy is directed by the optical fibers toward targeted regions of the obstruction. As the catheter is advanced and the process repeated, a core is formed from the obstruction and contained within the flexible portion. The flexible portion is then contracted to hold the core, and the core is removed from the body passage by withdrawing the catheter.

A method for removing sludge from a petroleum storage tank is based on a two-step approach utilizing solvent extraction to dissolve organic components of the sludge followed by water wash to remove inorganic materials. Sludges contain both organic-based solids (e.g., waxes and asphaltenes) as well as inorganic-based solids (known to exist as salts such as chlorides, carbonates, and oxides). The organic components of the sludge are dissolved using petroleum-based solvent streams that have been identified to possess high solvent power. The dissolved material can then be processed and recovered in the refinery using conventional refining operations. A water wash following removal of the organic materials is effective to remove the inorganic materials that can then be disposed of without the complications of the having to treat the oily organics along with them. A beneficial part of the method includes mixing and heating to improve the dissolution of soluble materials in both steps of the process.
