US 5,928,260 A · Removable occlusion system for aneurysm neck

Abstract

A system for treating an aneurysm in a vessel includes a delivery device having a delivery portion suitable for delivery of embolic material. The delivery device is placed in a neck of the aneurysm and an expandable member is placed proximate the neck. The expandable member is expanded to overlie substantially the entire neck. Embolic material is delivered to the aneurysm with a delivery device. The expandable member is held over the neck to inhibit movement of the embolic material out of the aneurysm. Blood is allowed to flow out of the aneurysm, past the neck of the aneurysm, and through the vessel while the expandable member is held over the neck of the aneurysm.

Dependent claims

A system for treating an aneurysm in a vessel, the aneurysm having a neck communicating with the vessel, the system comprising:

an embolic material;
and
a delivery catheter adapted for delivering the embolic material to the aneurysm, the delivery catheter comprising:
a first elongate member;
a second elongate member longitudinally movable relative to the first elongate member;
a tubular expandable member radially expandable and contractible in response to longitudinal movement of the first and second elongate members relative to one another;
and
wherein the expandable member is configured, when overlying the neck of the aneurysm, to allow delivery of embolic material to the aneurysm, to inhibit the embolic material from moving out of the aneurysm into the vessel, and to allow blood to flow through the vessel and to flow out of the aneurysm during delivery of the embolic material into the aneurysm.
