A medical device, such as a prosthesis, and method of forming the same are disclosed. The medical device includes a cover material and a reinforcement element, and may include a stent frame structure. The reinforcement element includes a plurality of bends disposed about a pattern axis. The pattern axis is arranged helically along the cover material.

A complex coil and a fixture for forming same configured such that loops are formed having various configurations relative to each other. The configurations provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

A flat embolic braid having a first side comprising a first side surface, and a second side comprising a second side surface facing in an opposite direction than the first side surface, the braid having an elongated constrained configuration for being deployed through a delivery catheter, and a three-dimensional unconstrained configuration, wherein in the three-dimensional unconstrained configuration, the braid assumes a plurality of successive loops in which the braid is at least partially twisted between successive loops of the plurality, so that the first side surface faces externally of each loop, and the second side surface faces an interior of each loop, respectively, regardless of a change in direction and/or orientation of the braid.

The present invention relates to a stent that uses a shape memory alloy wire, the stent being an expansion device installed on a part of a body lumen, which is constricted, or which has been constricted, so as to widen the passage of the lumen in response to the lesion part. The purpose of the present invention is to provide a method for manufacturing a stent using a shape memory alloy wire such that the stent maintains a high degree of conformability in a bent portion of a body lumen in which the same is inserted while substantially improving rigidness and durability against continuously applied fatigue, a stent manufactured thereby, and a jig for manufacturing the same.

A system and a method is provided in which a CAD system receives a solid model and receives user input to select points on the surface of the solid model, to create a wire part program file based on the selected points, and to transmit the wire part program file to a bending machine. The wire part program files is configured such that the bending machine will manufacture a wire based on the wire part program file.

An occlusive device, occlusive device delivery system, method of using, and method of delivering an occlusive device, and method of making an occlusive device to treat various intravascular conditions is described.

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.

A method of manufacturing a flexible catheter with a locatable sensor includes simultaneously rotating first and second spools about a common axis, whereby first and second leads of a wire twist together to form a twisted pair of the wire, and rotating a catheter body about a longitudinal axis defined by the catheter body, whereby the twisted pair of the wire wraps about a proximal end portion of the catheter body.

A flat embolic braid having a first side comprising a first side surface, and a second side comprising a second side surface facing in an opposite direction than the first side surface, the braid having an elongated constrained configuration for being deployed through a delivery catheter, and a three-dimensional unconstrained configuration, wherein in the three-dimensional unconstrained configuration, the braid assumes a plurality of successive loops in which the braid is at least partially twisted between successive loops of the plurality, so that the first side surface faces externally of each loop, and the second side surface faces an interior of each loop, respectively, regardless of a change in direction and/or orientation of the braid.
