Abstract
An occlusive system for the vasculature and an embolic coil used in such an occlusive system is described. Also described is an occlusive plug which can be used for occlusive purposes within the vasculature.
Claims39
A vascular disorder treatment system comprising:
- a first tube;
- a second tube slidably movable within said first tube;
- a containment device associated with a distal end of said second tube;
- said containment device having a non-expanded state and an expanded state;
- said containment device sized to seat said containment device at an entrance of a vascular disorder when in said expanded state;
- said containment device having an opening for receiving an embolic agent for treatment of said vascular disorder.
3 more elements
An apparatus for occluding a vascular site comprising:
- a first catheter;
- a second catheter movable within said first catheter;
- an occlusion protective device associated with a distal end of said second catheter;
- said occlusion protective device having a non-deployed state and a deployed state;
- said occlusion protective device sized and shaped to seat said occlusion protective device at an entrance of a vascular disorder when in a substantially deployed state;
- said occlusion protective device having an opening for receiving an embolic agent for treatment of said vascular site.
3 more elements
A method of occluding a vascular disorder comprising:
- positioning a catheter at said vascular disorder;
- deploying a embolic containment device from said catheter at an entrance of said vascular disorder;
- expanding said embolic containment device such that said embolic containment device is seated at said entrance of said vascular disorder;
- introducing an embolic agent into said vascular disorder through an opening of said embolic containment device.
1 more element
An embolic coil comprising:
- a coupler for connecting said coil to a delivery pusher;
- at least one sheet fixed to said coil.
A vascular occlusion device comprising:
- a first support layer comprised of multiple struts;
- a first occlusion layer associated with said first support layer;
- said first occlusion layer having a porosity to limit blood flow through said occlusion device.
