Embodiment Construction

[0080] There remains a clinical need for improved endoluminal filter devices and methods. The improved intraluminal filter device provides effective filtration across a range of lumen sizes and is easy to deploy into and retrieve from the lumen. Additionally, the improved intraluminal filter device minimizes thrombus formation or tissue ingrowth on the device and does not migrate along the lumen. Embodiments of the filter device of the present invention address many—and in some cases all—features of an improved intraluminal filter and have numerous applications such as, but not limited to: embolic protection, hemoplasty, vascular Occlusion, and tethered or non-tethered distal protection.

[0081] Several embodiments of the present invention provide durable and improved filter devices, provide effective and nearly constant filter capacity over a range of lumen sizes, and are easily delivered or removed from the lumen by either end of the device. Additionally, the embodiments ...

Abstract

An endoluminal filter including a first support member having a first end and a second end and a second support member attached to the first end of the first support member or the second end of the first support member and forming a crossover with the first support member. The endoluminal filter also includes a material capture structure extending between the first and second support members, the crossover and the first end or the second end of the first support member and at least one tissue anchor on the first support member or the second support member. A method of positioning a filter within a lumen including advancing a sheath containing a filter through the lumen. Next, deploying a portion of the filter from the sheath into the lumen to engage the lumen wall while maintaining substantially all of a material capture structure of the filter within the sheath. Next, deploying the material capture structure of the filter from the sheath to a position across the lumen.
