Abstract
An aneurysm embolization device and deployment system for use in occluding the flow of blood at a preselected position within a vessel of the human body comprising a headpiece and a plurality of spherical members linked together with a central connecting member, which, when deployed the embolization device occludes the flow of blood in a high volume or wide neck aneurysm.
Claims9
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 vessels of the body;
- an embolization device including a headpiece having a proximal section and a distal section;
- 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 carried by said central connecting member;
- 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 catheter releases the headpiece at the preselected position.
A method for placing an aneurysm embolization device at a pre-selected position within a vessel, the method comprising the steps of:
- providing a deployment catheter having a small diameter lumen extending therethrough and being formed of a material which is sufficiently flexible to pass through the vessels of the body, providing an aneurysm embolization device including a headpiece coupled to the distal end of the said deployment catheter;
- the embolization device includes a central connecting member which takes the form of a flexible fiber, and is attached to the headpiece, and the embolization device includes a spherical member which takes the form of a small spherical ball which is attached to the central connecting member;
- introducing said deployment catheter with said aneurysm embolization device into a vessel and positioning said aneurysm embolization device at a pre-selected position within the vessel;
- and,
- releasing said aneurysm embolization device at the preselected site with the vessel.
