Abstract[English]
A cardiac guidewire (20) is provided that is advanceable to a target cardiac site (10). The cardiac guidewire (20) is shaped so as to define an elongate portion (22), which is straight when unconstrained, and a spiral distal portion (24), which extends from and is supported by a distal end (26) of the elongate portion (22). The cardiac guidewire (20) is configured such that the spiral distal portion (24), when in an unconstrained resting state, is shaped as a spiral (30) that (a) spirals radially outward at an increasing distance from the distal end (26) of the elongate portion (22) so as to define an outer turn (32), and (b) has a zero or non-zero height. The cardiac guidewire (20) is further configured such that pushing of the elongate portion (22) in a distal direction (34), when the outer turn (32) of the spiral (30) engages cardiac tissue (36) at the target cardiac site (10), changes the height of the spiral (30) and deforms the spiral (30). Other embodiments are also described.[French]
Fil-guide cardiaque (20) pouvant être avancé vers un site cardiaque cible (10). Le fil-guide cardiaque (20) est formé de manière à définir une partie allongée (22), qui est droite lorsqu'elle n'est pas contrainte, et une partie distale en spirale (24), qui s'étend depuis une extrémité distale (26) de la partie allongée (22) et est supportée par celle-ci. Le fil-guide cardiaque (20) est configuré de telle sorte que la partie distale en spirale (24), lorsqu'elle est dans un état de repos non contraint, a la forme d'une spirale (30) qui (a) s'enroule en spirale radialement vers l'extérieur à une distance croissante à partir de l'extrémité distale (26) de la partie allongée (22) de façon à définir une spire externe (32), et (b) a une hauteur nulle ou non nulle. Le fil-guide cardiaque (20) est en outre configuré de telle sorte que la poussée de la partie allongée (22) dans une direction distale (34), lorsque la spire externe (32) de la spirale (30) vient en prise avec un tissu cardiaque (36) au niveau du site cardiaque cible (10), change la hauteur de la spirale (30) et déforme la spirale (30). D'autres modes de réalisation sont également décrits.
