Abstract:
An aneurysm embolization device and deployment system for use in placing said embolization device at a preselected position within a vessel of a human body, said embolization device and deployment system comprising:a deployment catheter having a small diameter lumen extending therethrough and having a proximal section and a distal section, said catheter being formed of a material which is sufficiently flexible to pass through the vessel of the body, the proximal section of said catheter exhibiting the characteristic of having substantially no radial expansion when fluid pressure is applied to the lumen of said catheter, and the distal section of said catheter exhibiting the characteristic that, when fluid pressure is applied to the lumen of said catheter the distal section of said catheter expands radially; a headpiece having a proximal section and a distal section, the distal section of said headpiece takes the form of a hemisphere and the proximal section of said headpiece takes the form of a cylinder; a central connecting member which takes the form of a flexible fiber, said connecting member having a proximal end and a distal end, the proximal end of said connecting member being attached to the distal section of said headpiece; a spherical member which takes the form of a small diameter ball, said spherical member being disposed about the distal end of said central connecting member; a connector coupled to the proximal section of said deployment catheter and adapted for a fluid pressure generating device; and, said proximal section of said headpiece being disposed within the distal section of said deployment catheter so that when a fluid pressure is applied to the lumen of said catheter the distal section of said catheter expands radially thereby releasing said headpiece.
