  • Patent number: 10287203
    Abstract: A method of drawing a material into sheet form includes forming a preform comprising at least one material as a large aspect ratio block wherein a first transverse dimension of the preform is much greater than a second transverse dimension substantially perpendicular to the first transverse dimension. A furnace having substantially linearly opposed heating elements one spaced from the other is provided and the heating elements are energized to apply heat to the preform to create a negative thermal gradient from an exterior surface along the first transverse dimension of the preform inward toward a central plane of the preform. The preform is drawn in such a manner that the material substantially maintains its first transverse dimension and deforms across its second transverse dimension.

    Abstract: A device is provided for collapsing a stented bioprosthetic valve, including first section and second sections, each spanning between first and second ends of the device. The second section of the device is associated with the first section to at least partially enclose an internal cavity formed by the first and second sections, the internal cavity tapering from an open insertion portion at a first end of the device to an open exit portion at a second end of the device. The insertion portion has a larger dimension than the exit portion. When the first section and second section are substantially enclosing the internal cavity, a stented bioprosthetic valve may be inserted into the insertion portion and collapsed as it is moved toward and through the exit portion. The valve may then be loaded on an apparatus for insertion into the body.

The Ni—Ti alloy that includes nickel, titanium, and about 3 atomic % (at %) to about 30 at % niobium (Nb). Cold working the Ni—Ti alloy stabilizes the alloy's martensitic phase and yields a linear pseudo-elastic microstructure where reversion to the austenite phase is retarded or altogether blocked. The martensitic phase of cold worked, linear pseudo-elastic Ni—Ti—Nb alloy has an elastic modulus that is considerably higher than the comparable cold worked, linear pseudoelastic binary Ni—Ti alloy. This yields a guide wire device that has better torque response and steerability as compared to cold worked, linear pseudoelastic binary Ni—Ti alloy or superelastic binary Ni—Ti alloy.

Provided is a method for producing a metal wire 1 including a process of drawing a metal wire by using a slip type drawing machine. For a cone 11 of the slip type drawing machine, a cone having an even surface without an inclination angle with respect to the axis of rotation is used, as well as, a die 12 of the slip type drawing machine is positioned such that the metal wire 1 passes a location nearest to a drive unit in the direction parallel to the axis of rotation of the cone 11.

    Abstract: A system for manufacturing wire having a mill and a finishing station configured to receive the wire output from the mill in a continuous fashion. The mill has first and second dies and first and second capstans. The first die is configured to receive a wire having a first cross-sectional area and to reduce the cross-sectional area of the wire as it passes through the first die. The first capstan is configured to receive the wire from the first die and apply a first force on the wire. The second die is configured to receive the wire from the first capstan and to further reduce the cross-sectional area of the wire as it passes through the second die. The second capstan is configured to receive the wire from the second die and apply a second force on the wire. The wire exits the mill having a second cross-sectional area that is smaller than the first cross-sectional area, and is finished by the finishing station.

  • Patent number: 7950126
    Abstract: Improved cored-wire fabrication replaces multiple roller pairs with one or more dies. In the preferred embodiment, flat stock is pulled through a single cylindrical die including an upper tab to ensure and orient the formation of a gap to receive internal powders. Once the powders are introduced, a cylindrical die is used for closure though again, one or more rollers may be used between the powder feed and the die used for closing. In the preferred embodiment, however, a single gap-forming die is used before the powder feed, and a single closing die is used after the powder feed, replacing numerous rollers and other moving parts, thereby dramatically simplifying the apparatus and method of manufacture.
