Abstract
A device for treating balloon-type (or berry) aneurysms is provided. The device restricts blood flow into the aneurysm with a patch that covers the neck of the aneurysm. The patch is secured within the neck of the aneurysm by an anchor member, basket, insert or other structure that engages the inner surface of the aneurysm.
Claims22
An aneurysm basket comprising:
- a basket wall extending between a proximal basket end and a distal basket end, wherein the basket wall encloses a cavity and the proximal basket end comprises a ring;
- a basket neck region extending between the proximal basket end and a distal neck end;
- a spherical region extending between the distal neck end and the distal basket end;
- and
- a plurality of wires, wherein the plurality of wires comprise a plurality of proximal wire ends, the plurality of wires comprise the basket wall, and the plurality proximal wire ends comprise the proximal basket end.
A device for treating an aneurysm, comprising:
- an anchor member expandable between a collapsed state and an expanded state, the anchor member being adapted to be implanted intravascularly into an aneurysm, wherein the anchor member extends between a proximal anchor end and a distal anchor end;
- and
- a patch made of a covering material attached to the proximal anchor end, the patch adapted to cover a neck of the aneurysm;
- wherein the anchor member secures the patch to the neck of the aneurysm thereby restricting blood flow into the aneurysm.
An aneurysm insert comprising:
- a body, said body comprising an insert neck region extending between a proximal insert end and a distal neck end, the insert neck region being adapted to be inserted into a neck region of an aneurysm;
- and an insert spherical region extending between the distal neck end and a distal insert end, the insert spherical region being adapted to be inserted into a spherical interior region of an aneurysm, wherein at least a portion of the body is a compressible material.
A sealing apparatus for sealing a dilatation area of a body vessel from an aneurysm, the apparatus comprising:
- a sealing device including:
- a basket having an opening formed thereon defining a sealing lip, the basket configured to be introduced in the aneurysm to maintain the position of the sealing device at the dilatation area of the body vessel;
- a base attached to the sealing lip closing the opening, the base having connective tissue disposed thereon for tissue repair at the dilatation area of the body vessel, the connective tissue being configured to contact the body vessel to seal the dilatation area;
- an introducer sheath through which the sealing device is disposed for percutaneous insertion into a body vessel;
- a catheter having proximal and distal ends, and being configured to be passed through the introducer sheath to position the catheter in the body vessel, the catheter having a hub adjacent the proximal end;
- and
- a pusher wire for advancing the sealing device and adjusting the placement thereof during deployment into the body vessel.
An aneurysm insert adapted for intravascular delivery to the interior of an aneurysm, the insert comprising a structure that in a rest state intrinsically defines an exterior spheroidal surface, the structure being compressible to enable passage through a neck of the aneurysm.
