Angioplasty apparatus comprises a hand-held unit 28 which reciprocates a wire 24 within a catheter 26. It is found that, by using a highly flexible wire and a reciprocation frequency of 50-1000 Hz a diffuse vibration is caused at the distal end of the wire, which enables the wire to pass relatively easily through difficult blockages.
Un dispositif d'angioplastie comprend une unité (28, 8) portative qui applique un mouvement alternatif à un fil (24, 6) se trouvant dans un cathéter (26, 2). Il a été découvert que l'utilisation d'un fil très souple et d'une fréquence d'alternance de 50 à 1000 Hz produit une vibration diffuse, au niveau de l'extrémité distale du fil, qui permet au fil de traverser relativement aisément des obstructions importantes.
