Abstract
A self-expanding, pseudo-braided device embodying a high expansion ratio and flexibility as well as comformability and improved radial force. The pseudo-braided device is particularly suited for advancement through and deployment within highly tortuous and very distal vasculature. Various forms of the pseudo-braided device are adapted for the repair of aneurysms and stenoses as well as for use in thrombectomies and embolic protection therapy.
Claims17
A method involving employing a device for use in embolic therapy within vasculature having an aneurysm sac, comprising:
- gaining access to vasculature;
- placing within an aneurysm sac a device including an elongate filament configured into a pseudo-braided pattern and formed to define a generally tubular body with a first end and a second end;
- and
- configuring the body to facilitate thrombus formation within the aneurysm sac, said first and second ends each being defined by a plurality of endless reversals of direction of said filament.
A method involving employing a device for use in embolic therapy within vasculature having an aneurysm sac, comprising:
- gaining access to vasculature;
- placing a device including an elongate filament configured into a pseudo-braided pattern and formed to define a generally spherical body within a delivery microcatheter, said generally spherical body formed by a generally tubular body having first and second ends that are collapsed upon themselves, said first and second ends each comprising a plurality of endless reversals of direction of said filament the spherical body shaped to facilitate thrombus formation within the aneurysm sac, the delivery microcatheter releasably connected to said spherical body;
- placing the delivery microcatheter within vasculature;
- and
- deploying the device to facilitate thrombus formation within an aneurysm sac.
