A guidewire for use in guiding the insertion of catheters bears a plurality of unique identifiers. These unique identifiers are used to choose the appropriate length of catheter to be inserted into the patient. Many of the steps of marking and measuring a guidewire and calculations utilizing the measurements are eliminated through use of this catheter bearing unique identifiers. In place of the detailed and error prone set of marking, measuring and calculating steps, a set of unique identifiers are printed or otherwise directly and immovable associated with the guidewire. A practitioner determines the stock length of catheter needed in a procedure merely by noting the placement of one unique identifier relative to a standard landmark.

L'invention porte sur un fil de guidage destiné à être utilisé pour guider l'insertion des cathéters et comportant une pluralité d'identificateurs uniques. Ces identificateurs uniques sont utilisés pour choisir la longueur appropriée du cathéter à insérer dans le corps du patient. En utilisant ce cathéter portant des identificateurs uniques, il n'est plus nécessaire de procéder aux étapes de marquage et de mesure d'un fil de guidage et aux étapes de calcul en utilisant les mesures effectuées. Un ensemble d'identificateurs uniques, imprimés ou directement associés de manière fixe au fil de guidage, remplace les étapes de marquage, de mesure et de calcul, susceptibles d'entraîner des erreurs. Un praticien détermine la longueur du cathéter nécessaire à une intervention en notant simplement l'emplacement d'un identificateur unique par rapport à un point de repère anatomique standard.
