Abstract
A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed.
Claims20
A method of treating an intracranial aneurysm comprising the steps of:
- a) providing an occluding device having a lumen therein;
- b) providing a delivery catheter and a delivery member slidable within the delivery catheter, the delivery member supporting the occluding device;
- c) inserting the delivery member with the occluding device into the intracranial aneurysm, the delivery member retaining the occluding device during delivery of the occluding device to the intracranial aneurysm;
- and
- d) retracting the delivery member proximally from adjacent a distal opening within the lumen of the occluding device to a first stop to provide a gap to create a filling action through a capillary effect for blood flow through the distal opening and into the lumen of the occluding device and towards a proximal end of the occluding device while the occluding device is still retained by the delivery member.

A method of treating an intracranial aneurysm comprising the steps of:
- a) providing an occluding device having a distal opening, a lumen therein and a tubular marker band at a proximal portion;
- b) providing an elongated member extendable into the tubular marker band of the occluding device;
- c) inserting the elongated member and the occluding device through vasculature toward the intracranial aneurysm, the elongated member preventing release of the occluding device into the intracranial aneurysm;
- and
- d) retracting the elongated member proximally from adjacent the distal opening through the lumen of the occluding device to create a filling action through a capillary effect for blood flow proximally into the space previously occupied by the elongated member.
