Intravascular device

A device for producing occlusion of a vessel or an aneurysm, comprising:

• an intravascular device for placement within a patient, the intravascular device having a lead element, and a trailing element connected by a non-metallic member to the lead element;
• a detachment apparatus engaging the trailing element of the intravascular device;
• an introducing catheter having a distal end, the intravascular device being inserted into the introducing catheter, whereby the intravascular device may be positioned to occlude at least a portion of the vessel or the aneurysm, and the intravascular device may then be disengaged from the detachment apparatus.

A device for producing occlusion of a vessel or an aneurysm, comprising:

• an intravascular device having a lead element, and a non-spherical trailing element connected to the lead element;
• a detachment apparatus engaging the non-spherical trailing element of the intravascular device;
• an introducing catheter having a distal end, the intravascular device being inserted into the introducing catheter, whereby the intravascular device may be positioned to occlude at least a portion of the vessel or the aneurysm, and then may be disengaged from the detachment apparatus.

A device for producing occlusion of a vessel or an aneurysm, comprising:

• an intravascular device having a lead element, and a trailing element comprising a coil connected to the lead element;
• a detachment apparatus engaging the trailing element of the intravascular device;
• an introducing catheter having a distal end, the intravascular device being inserted into the introducing catheter, whereby the intravascular device can be positioned to occlude at least a portion of the vessel or the aneurysm, and the intravascular device may then be disengaged from the detachment apparatus.

A device for producing occlusion of a vessel or an aneurysm, comprising:

• an intravascular device having a lead element, and a trailing element connected to the lead element, the trailing element being configured to anchor the intravascular device within the vessel or aneurysm;
• a detachment apparatus which engages the trailing element of the intravascular device;
• an introducing catheter having a distal end, the intravascular device being inserted into the introducing catheter, whereby the intravascular device can be positioned to occlude at least a portion of the vessel or the aneurysm, and the intravascular device can then be disengaged from the detachment apparatus.
