Abstract:
A vascular occlusive coil deployment system comprising:a catheter having a tubular wall and having a lumen extending throughout the length of the catheter, said catheter further having a proximal section and a distal section, said distal section of the catheter being formed from a material which exhibits the characteristic that the wall of the distal section of the catheter expands outwardly when a liquid is applied within the lumen of the catheter; a syringe coupled to said proximal section of the catheter for applying the liquid within the lumen of the catheter; an embolic coil having a proximal end and a distal end, said proximal end of the embolic coil being disposed in fluid-tight engagement within said lumen of the distal section of the catheter, said proximal end of the embolic coil being released when the liquid is applied within the lumen of the catheter and the wall of the distal section of the catheter expands outwardly; and, at least one aperture for purging air from said lumen of the catheter, said aperture extending radially through said wall of the distal section of the catheter at a point proximal to the proximal end of the embolic coil.
