Abstract:
A vasoocclusive coil deployment system for use in placing a coil at a preselected site within a vessel comprising:an elongated flexible catheter having a lumen extending therethrough and having a proximal section and a distal section, said distal section of the catheter being formed of a material having a durometer which exhibits the characteristic that when a fluid pressure is applied to the lumen of the catheter the walls of the distal section of the catheter expand outwardly; an embolic coil being disposed in fluid-tight engagement within the lumen of the distal section of the catheter; and, a source of fluid pressure coupled to the proximal section of the catheter for upon actuation applying fluid pressure to the lumen of the catheter to thereby cause the distal section of the catheter to expand outwardly to thereby release the embolic coil.
