A guide wire for minimally invasive operations with a distal wire end piece (3, II) connected to a wire main piece (2), wherein the guide wire (I, 10) has, at least in the distal wire end piece (3, II), an inner shaft (4, 14) and at least one protective layer enclosing the inner shaft (4, 14), the inner shaft (4, 14) comprises a first fibre composite material and, at least in the distal wire end piece (3, II), the inner shaft (4, 14) has a plurality of weakened points (8, 18), which are created by mechanical interventions, is characterised in that the weakened points (8, 18) are created by buckling load, bending load and/or breaking load. Correspondingly, for a method for producing a guide wire of this kind it is proposed that the weakened points (8, 18) are created by buckling load, bending load and/or breaking load.

A manipulator, including an elongated chassis containing a U-shaped channel defining a distal direction and a proximal direction. The manipulator also includes an adjuster that is configured to slide in the U-shaped channel. The adjuster includes a first wheel which on rotation translates a guidewire positioned in the adjuster along an axis of the guidewire, and a second wheel which on rotation rotates the guidewire positioned in the adjuster about the axis of the guidewire. The adjuster also includes a port, distal to the first and the second wheel, that is configured to accept a tubular balloon and the guidewire.

A medical probe includes a guidewire, a magnetic position sensor, and an ultrasound (US) transducer. The guidewire is configured for insertion into a blood vessel of a patient. The magnetic position sensor is fitted at a distal end of the guidewire and is configured to produce signals indicative of a position of the distal end. The US transducer is fitted at the distal end of the guidewire and is configured to transmit US waves inside the blood vessel, and acquire respective US echoes indicative of blood velocity in the blood vessel.

A method is used to manufacture a surgical guidewire that includes an outer coil assembly, a position sensor, a communication wire, an adhesive, a core wire, a hollow tube, and an atraumatic tip. The outer coil assembly has an outer coil that extends distally from a proximal coil retainer to a distal coil retainer. The position sensor is located distally within the outer coil assembly and is configured to be in communication with a processor via the communication wire. The core wire is between an outer coil proximal portion and the hollow tube. A distal end of the hollow tube is bonded to the atraumatic tip. The method includes affixing the atraumatic tip to the distal end of the hollow tube with the adhesive. The adhesive is constructed of instant glue.

This disclosure describes a micro-cutting machine for forming cuts in catheters, guidewires, and similar products. The micro-cutting machine can directly control the dimensions of the resultant beams being cut into these types of products, and can also capture images of each cut for feedback control and accuracy verification. The micro-cutting machine has two cutting blades each with cutting edges aligned with a vertical axis. Motors operate to move the cutting blades in a direction perpendicular to the longitudinal axis of the stock material being cut to form a pair of opposing grooves in the stock material with each cut.

A method of treating a patient includes providing a guidewire having an elongate body defining a proximal end and a distal end, the elongate body including a shapeable portion disposed proximate the proximal end, the shapeable portion being malleable so as to be shaped into a shape and remain in the shape until reshaped. The distal end of the elongate body is advanced into a vasculature of the patient. The shapeable portion of the elongate body is shaped into a first shape that prevents advancement of the guidewire further into the vasculature of the patient.

A medical guide wire which can have both slidability and operability and can be easily manufactured is provided. A medical guide wire includes a long flexible wire body, and a wire-like material structure including a wire-like material arranged on the surface of the wire body, in which the wire-like material structure is thermally fused onto the wire body.

The present disclosure provides an improved guidewire assembly including a sensor disposed on a distal portion thereof and a proximal connector disposed on a proximal portion thereof for electrically coupling the guidewire assembly to an external device. The proximal connector comprises at least one proximal contact and at least one reflowed insulative element disposed adjacent the at least one proximal contact.

Provided is a guide wire having a novel structure, with which it is possible to improve production efficiency and to effectively prevent large irregularities from forming on an outer circumferential surface of a core wire. Further provided is a guide wire having a novel structure, with which it is possible to more meticulously set bending rigidity to a distal end portion thereof. In a guide wire having a coil externally mounted about a distal end portion of a core wire, a proximal end portion of the coil is integrally joined to the core wire during formation of the coil. Furthermore, in a guide wire having a coil externally mounted about a distal end portion of a core wire, a cross-sectional shape of a wire that constitutes the coil varies in a lengthwise direction of the coil.
