Connection joints for joining wires and pads constructed of different conductive materials and methods of making the same
10912940 · 2021-02-09 · ·

An exemplary connection joint includes a wire constructed from a first conductive material having a first melting point and a pad constructed from a second conductive material different from the first conductive material and having a second melting point lower than the first melting point. The connection joint further includes a groove within the pad that partially surrounds the wire and a fixative covering the wire and the pad so as to fix the wire in place within the groove. The groove is formed by a displacement of the second conductive material that occurs when the wire is in contact with the pad at a contact area of the pad that is heated to a temperature between the first and second melting points so as to reflow the second conductive material from which the pad is constructed without reflowing the first conductive material from which the wire is constructed.

An ultrasonic welding assembly joins bare ends of an insulated wire bundle to a wire terminal in a weldment zone by intimate contact with a sonotrode of an ultrasonic stack. A door allows the operator to place the terminal into the nest within the weldment zone. One operator hand holds the wire bundle while one contacts an external sensor. A pair of terminal clamps extend inwardly and down to secure the terminal and create a taller capture area for the loose bare wire ends. A pair of clamp finger assemblies reversibly extend towards the insulated wires away from the weldment zone for securing the wires. A wire gatherer descends upon and captures all of the wire bare ends and secures them until the horn descends, captures, and holds the wire ends in place, then extends away from the weldment zone for ultrasonic welding to commence.

GUIDEWIRE HAVING RADIOPAQUE INNER COIL

A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.
