Guide-wire kit and assembly, use and mounting method

Abstract

Described herein is a method using an assembly having a guide-wire having distally a flexible tip, and a guide-wire kit having comprising an introduction element of the guide-wire, a torque body, proximal to the introduction element, which includes blocking element of the guide-wire to-the body, and a slide control which defines a support surface for the guide-wire, manually accessible to control (roto-)translations of the guide-wire, thereby orientations and/or sliding of the flexible tip, when the blocking element is in a release configuration. The torque body, the introduction element and the slide control are each diesengageable, independently of the others, from the guide-wire in a radial direction.

What is claimed is: 
     
         1 . Method of using, inside or outside the human body, an assembly of a guide-wire comprising the steps of:
 providing a guide-wire which extends along a main direction and which comprises distally a flexible tip;   providing an introduction element of the guide-wire kit, which identifies an inner space and which is tapered in a distal direction;   inserting the guide-wire in the inner space of the introduction element;   providing a slide control of the guide-wire kit, which defines a support surface for the guide-wire;   manually controlling (roto-)translations of the guide-wire, thereby orientations and/or sliding of the flexible tip, working with a finger/thumb on the support surface and on the guide-wire;   disengaging the introduction element and/or the slide control from the guide-wire in a radial direction;   and preferably comprising the further steps of:   providing a torque body of the guide-wire kit, which delimits internally a longitudinal passage and which comprises blocking means of said guide-wire in relation to said body, suitable for being reversibly switched;   housing part of the guide-wire in the longitudinal passage in a radial direction;   proximally to the introduction element, connecting the torque body to the slide control, for example by means of a shaped coupling, so that said slide projects in part from the torque body in a distal direction;   optionally disengaging the torque body from the guide-wire in a radial direction.   
     
     
         2 . Method of mounting a guide-wire assembly comprising the steps of:
 providing an introduction element of a guide-wire in an artery, which identifies an inner space and which is tapered in a distal direction to create an opening through an introduction catheter;   providing a torque body, proximal to the introduction element, which delimits internally a longitudinal passage and which comprises blocking means of said guide-wire to said body, suitable for being reversibly switched between a retention configuration wherein said means work on such guide wire to block it, and a release configuration to permit movements of the guide-wire in relation to said body;   providing a slide control which defines a support surface for the guide-wire, manually accessible to control (roto-)translations of the guide-wire, therefore orientations and/or sliding of the flexible tip, when said means are in the release configuration;   connecting the torque body, the introduction element and the slide control to each other.   
     
     
         3 . Mounting method according to  claim 2 , comprising a step of receiving, partially or mainly, the slide control in a slide seat of the torque body to retain the guide-wire in the torque body. 
     
     
         4 . Mounting method according to  claim 2 , comprising the steps of:
 providing a guide-wire which extends along a main direction and which comprises distally a flexible tip;   said guide-wire being housed and progressively fed from a guide-wire container;   making the guide-wire transit in the inner space of the introduction element, in the longitudinal passage of the torque body and on the support surface of the slide control;   attaching the guide-wire container proximally to the torque body and/or to the slide control.
