Abstract

A device for at least partially occluding an aneurysm is disclosed. The device includes a first elongate member having a distal end. A bridge is positioned proximate the distal end and transformable between a delivery configuration and a deployed configuration. A second elongate member is movable relative to the first elongate member, the first and second elongate members being configured such that one can be moved relative to the other in order to transform the bridge between the delivery and deployed configurations.

Claims

1. A device for at least partially sealing an aneurysm, comprising:

a first elongate member having a distal end;

a bridge positioned proximate the distal end and transformable between a delivery configuration and a deployed configuration in which it forms a plurality of protruding members that extend from, and are radially disposed around, the first elongate member;

a second elongate member that is movable relative the first elongate member, the first and second elongate members being configured such that one can be moved relative the other in order to transform the bridge between the delivery and deployed configurations;

a clip for retaining said bridge in the deployed configuration; and

a detachment zone of material proximally located relative to the bridge and the distal end of the first elongate member when said detachment zone of material is in a connected configuration, wherein the detachment zone of material is a GDC detachment zone.

2. A device for at least partially sealing an aneurysm comprising:

a first elongate member having a proximal end, a distal end and an elongated length therebetween;

a clip assembly attached proximate to the distal end of the first elongate member and having a clip that is moveable between a first position and a second position, said clip assembly comprising a tube having a slot formed therein and an extension piece that extends through the slot when the clip is in the second position and is retracted within the tube when the clip is in the first position; and

a bridge positioned proximate to the clip assembly and expandable between a delivery configuration when the clip is in the first position, and a deployed configuration when the clip is in the second position.

3. The device of claim 2 wherein a portion of the extension piece is attached within the tube.

4. A device for at least partially sealing an aneurysm comprising:

a first elongate member having a proximal end, a distal end and an elongated length therebetween;

a clip assembly attached to the distal end of the first elongate member and having a clip that is moveable between a first position and a second position said clip disposed substantially within said bridge when in said first position, and said clip extending at least partially outside of said bridge said bridge when in said second position; and

a bridge positioned proximate to the clip assembly and expandable between a delivery configuration when the clip is in the first position, and a deployed configuration in which it forms a plurality of protruding members that extend from, and are radially disposed around, the first elongate member, when the clip is in the second position such that said clip retains said bridge in the deployed configuration; and

a detachment zone of material proximally located relative to the clip when said detachment zone of material is in a connected configuration, wherein the detachment zone of material is a GDC detachment zone.
