BRAIDED MEDICAL DEVICES

A braided vaso-occlusive member formed out of first plurality of filaments interwoven with a second plurality of filaments, wherein filaments of the first plurality are helically wound in a first rotational direction along an elongate axis of the braided member, and filaments of the second plurality are wound in a second rotational direction opposite the first rotational direction, such that filaments of the first plurality cross over and/or under filaments of the second plurality at each of a plurality cross-over locations axially spaced along the elongate axis of the braided member, wherein at each cross-over location, the filaments of the first plurality cross over at least two consecutive filaments of the second plurality, then cross under only a single filament of the second plurality, and then cross over at least two additional consecutive filaments of the second plurality.

Method for forming an endodontic instrument or device

Methods for manufacturing an endodontic instrument or device, such as an endodontic file for use in performing root canal therapy on a tooth, are disclosed. The method may include the steps of: (a) providing a wire or wire blank comprising a nickel titanium alloy that has been heat-treated at a heat-treat temperature and has an angle greater than 5 degrees of permanent deformation after torque at 45 degrees of flexion tested in accordance with ISO Standard 3630 Part 1: General requirements and test methods and (b) removing material from the wire or wire blank to form an endodontic instrument or device. The method may include the steps of: (a) providing a wire or wire blank comprising a nickel titanium alloy at a first temperature; and (b) removing material from the wire or wire blank at a second temperature above the first temperature to form an endodontic instrument or device.

SYSTEMS, DEVICES, AND METHODS FOR DESIGNING AND FORMING A SURGICAL IMPLANT
20200196996 · 2020-06-25 ·

A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

CONNECTION STRUCTURE AND GUIDE WIRE HAVING THE CONNECTION STRUCTURE
20200179658 · 2020-06-11 · ·

A connection structure includes a multi-thread coil formed by winding first metal element wires formed of a first metal and second metal element wires formed of a second metal arranged between a first metal body including the first metal and a second metal body including the second metal. The first metal body is connected to the first metal element wires of the multi-thread coil, and the second metal body is connected to the second metal element wires of the multi-thread coil. The connection structure imparts improved flexibility to the connection between the first and second metal bodies, and an appropriate connection can be provided even when the first and second metal bodies are made of dissimilar metals.
