Abstract
Methods and devices are disclosed for retaining embolic microcoils or other embolic materials within an aneurysm, such as a distal basilar artery aneurysm. The device includes a self expandable tubular support structure for positioning within the basilar artery. The support structure holds a barrier across the opening of the aneurysm.
Claims45
A basilar aneurysm occlusion device, comprising:
- a radially expandable support structure, moveable between a reduced cross section for transluminal navigation and an enlarged cross section for retention within the basilar artery;
- at least one axially extending link;
- and
- a basilar aneurysm patch attached to the link, and moveable between a reduced cross section orientation and an implanted orientation;
- wherein the patch resides in an axial orientation when in the reduced cross section orientation and a transverse orientation when in the implanted orientation.
A method of treating a distal basilar aneurysm, comprising the steps of:
- positioning an embolic material in a distal basilar aneurysm;
- positioning a tubular support structure within the basilar artery such that a retention element carried by the support inhibits escape of material from the aneurysm.
A self expandable bifurcation aneurysm occlusion device, comprising:
- a tubular support structure having a proximal end, a distal end, and a longitudinal axis;
- at least one strut extending distally from the support structure;
- and
- a barrier carried by the strut.
A device for obstructing the opening to an aneurysm, comprising:
- a self expandable wire support, having a proximal end, a distal end and a tubular wall extending therebetween, the wall comprising a plurality of struts connected by bends;
- an axially oriented opening at the proximal end of the support;
- a transverse barrier carried by the distal end of the support;
- and
- at least one lateral opening proximal to the transverse barrier.
A flow deflector, for implantation at a bifurcation in a vascular structure, comprising a support structure for positioning in a main vessel proximal to the bifurcation, the support structure having a proximal end, a distal end, and a longitudinal axis, and a flow deflection surface carried by the support structure, the flow deflection surface extending transversely across the longitudinal axis.
A method of isolating an aneurysm, comprising the steps of:
- positioning a neointimal cell growth support across the opening of an aneurysm;
- and
- holding the support in position using a retention structure positioned in a vessel outside of the aneurysm.
An embolic coil for treating an aneurysm, comprising:
- at least one embolic microcoil,
- a support, for retaining the microcoil in an aneurysm;
- and
- a strut, connecting the microcoil to the support.
