Occlusion device and method of use

A method for treating a vessel that is bifurcated into two branches, said method comprising the steps of:

• providing a catheter having first and second self-expandable occlusive members;
• inserting a first elongate member so as to cause the first self-expandable occlusive member to be in a radially collapsed state;
• inserting a second elongate member so as to cause the second self-expandable occlusive member to be in a radially collapsed state;
• inserting the catheter into the vessel such that the first self-expandable occlusive member is distal to a bifurcation of the vessel in one of the branches and the second self-expandable occlusive member is proximal to the bifurcation;
• retracting the first elongate member to allow the first self-expandable occlusive member to expand;
• and
• retracting the second elongate member to allow the second self-expandable occlusive member to expand.

A device comprising:

• a catheter having a distal portion, a proximal portion and at least one lumen extending therebetween, the catheter including first and second self-expandable occlusive baskets disposed over first and second longitudinally expandable portions of the catheter, respectively;
• and
• a first stylet insertable through a lumen of the catheter so as to cause expansion of the first longitudinally expandable portion of the catheter and transitioning of the first self-expandable occlusive basket from a radially expanded state to a radially collapsed state;
• and
• a second stylet insertable through the lumen of the catheter so as to cause expansion of the second longitudinally expandable portion of the catheter and transitioning of the second self-expandable occlusive basket from a radially expanded state to a radially collapsed state.

A device comprising:

• a catheter having a distal portion, a proximal portion and at least one lumen extending therebetween, the catheter including first and second self-expandable occlusive meshes disposed over first and second longitudinally expandable portions of the catheter, respectively;
• and
• a first stylet insertable through a lumen of the catheter so as to cause expansion of the first longitudinally expandable portion of the catheter and transitioning of the first self-expandable occlusive mesh from a radially expanded state to a radially collapsed state;
• and
• a second stylet insertable through the lumen of the catheter so as to cause expansion of the second longitudinally expandable portion of the catheter and transitioning of the second self-expandable occlusive mesh from a radially expanded state to a radially collapsed state.
