Title (EN) GUIDE WIRE INTRODUCER ASSEMBLY WITH GUIDE WIRE GRIP AND RELEASE MEANS
(FR) ENSEMBLE INTRODUCTEUR DE FIL DE GUIDAGE, POURVU DE MOYENS DE SERRAGE ET DE RELACHEMENT DE CE FIL
Abstract:
(EN) Introduction aid (9) for stretching one end of a guide wire (15) and securing the guide wire (15) in a dispenser tube (11), which aid has an elongate hollow element open at both ends, with an essentially cylindrical section (1) and a conical section (2) which tapers towards the distal end (3), a U-shaped slit (5) extending in the longitudinal direction being present in the wall (4) of the hollow element so that a tongue (6) which can be pressed into the inside of the hollow element is formed between the legs of the U-shaped slit (5) open towards the distal end (3), characterized in that the essentially cylindrical section (1) has at the proximal end an undercut (8), and a connection element (10) for connecting this introduction aid to the dispenser tube (11), which element has a proximal connector (12) for fastening the distal end of the dispenser tube (11), a tubular distal connector (13) onto which the introduction aid (9) can be pushed with its cylindrical section (1) and remains displaceable in the longitudinal direction after connection has taken place, and a central piece (7) located between them and having an advancing surface (17), which is freely accessible from outside, for the guide wire (15), a retaining means (20) being present on the distal connector (13) and/or at the distal end of the central piece (7) and gripping the undercut (8) of the introduction aid (9) at maximum excursion in the distal direction of the introduction aid which has been fitted onto the distal connector (13) in order to limit the movement of the aid in the longitudinal direction.
(FR) Ce dispositif introducteur (9), destiné à étirer une extrémité d'un fil de guidage (15) et à attacher ce fil (15) dans un tube distributeur (11), comporte un élément creux de forme allongée, ouvert sur ses deux extrémités et présentant une section cylindrique (1), une section conique (2) effilée vers l'extrémité distale (3), ainsi qu'une fente en forme de U (5) s'étendant dans la direction longitudinale et ménagée dans la paroi (4) de l'élément creux de manière à ce qu'une languette (6), qui peut être comprimée dans l'intérieur de l'élément creux, se forme entre les branches de la fente en U (5) ouverte vers l'extrémité distale (3). Ce dispositif est caractérisé en ce que la section essentiellement cylindrique (1) comprend au niveau de son extrémité proximale une contre-dépouille (8) ainsi qu'un élément de raccordement (10) destiné à relier ce dispositif introducteur au tube distributeur (11), lequel élément se compose d'un raccord proximal (12), servant à attacher l'extrémité distale du tube distributeur (11), d'un raccord distal tubulaire (13) sur lequel on peut pousser la section cylindrique (1) du dispositif introducteur (9), celui-ci restant mobile dans la direction longitudinale, après raccordement, ainsi que d'une pièce centrale (7) placée entre ces deux raccords et présentant une surface d'avancement (17) aisément accessible de l'extérieur et destinée au fil de guidage (15). Par ailleurs, des moyens de rétention (20) sont montés sur le raccord distal (13) et/ou au niveau de l'extrémité distale de la pièce centrale (7) et ils serrent la contre-dépouille (8) du dispositif introducteur (9) au niveau de la course maximum, dans la direction distale, du dispositif, lequel est ajusté sur le raccord distal (13) de manière à ce que son déplacement soit limité dans la direction longitudinale.
