A purpose of the present invention is to provide a technology that allows corrugated tubes of various diameter sizes to be easily and reliably cut at a convex portion. In order to achieve the purpose, a cutting device is provided with a feeder feeding a corrugated tube such that an axial direction of the corrugated tube lies along a feeding path; a cutter cutting along a circumferential direction of the corrugated tube being fed along the feeding path; and an imager capturing an image of a planned cutting position of the corrugated tube. A controller performs image analysis of the captured image of the planned cutting position to determine whether the planned cutting position is a convex portion of the corrugated tube and, when a positive determination result is obtained, causes the cutter to cut the corrugated tube at the planned cutting position.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

A method of cutting a control line mounted on an outer surface of a downhole tubular that includes providing a cutting tool having a main body, and a cutting head on a lower end of the body that rotates with respect to the body. A cutting blade is on a lower end of the cutting head, which is rotatable by a motor, where the blade is selectively pivoted radially outward from an axis of the cutting head. As the cutting head rotates, the cutting blade orbits within the tubular axially offset from the axis. When the tool is inserted into the tubular, the radial offset of the blade is controlled so it pivots radially outward into contact with the tubular when the blade approaches an azimuthal area proximate the control line. The cutting blade is retracted when its orbit moves it past the azimuthal area proximate the control line.

A rotary cutting apparatus includes a pair of cutting tools each having a cutting blade along a tip end of its outer peripheral portion having a mountain-shaped cross section, and cuts a cylindrical material into pieces with a predetermined width by sandwiching the cylindrical material between the cutting blades so the cutting blades are respectively placed on inner and outer peripheries of the cylindrical material, and relatively rotating and moving the pair of cutting tools along an entire circumference of the cylindrical material. A second imaginary line connecting an axial center of the cylindrical material and an axial center of the inner peripheral-side cutting tool is shifted in a circumferential direction of the cylindrical material about the axial center of the cylindrical material with respect to a first imaginary line connecting the axial center of the cylindrical material and an axial center of the outer peripheral-side cutting tool.

A cutting method and an apparatus are provided which enable a rim area or other part of a vitreous silica crucible to be cut off so as to leave a smooth cut surface without damaging the cut edge, etc. The apparatus for cutting the crucible comprises a disk-shaped cutting blade (10) disposed to be movable with respect to the crucible. Without rotating the crucible (20), the rotating cutting blade (10) is brought into contact with a surface of the crucible wall and pushed forward in the wall thickness direction to make a cut piercing the crucible wall. The cutting blade (10) is moved relatively to the crucible (20) in the circumferential direction of the crucible (20) while keeping the cutting blade in the state of piercing the wall. A rim area (25) of the crucible (20) is thus cut off.

A tool for manufacturing a cap for a container comprises a blade set that includes a plurality of knives. The knives are configured to make incisions in a cap having a main body having a top plate and a circular sidewall. The top plate has a top surface, wherein two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connects to one surface of the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end and a ring member, which is located at the opened end of the main body. There is a first tab on the ring member and a second tab on the sidewall.

A vascular filter device (1) has a support frame (2) and filter elements (4). The filter elements (4) extend from the support frame towards filter element ends forming an on-axis apex (5) at which they are interconnected by a holder (6). The filter elements (4) are biased such that if unconnected the filter element ends are located between the support frame and said central axis when the vascular filter device is unconstrained. The filter element unconnected positions are provided by the filter element shapes and the angles at which they extend from the support frame, and in one example this is achieved by laser cutting tubing and heat setting the material.
