Abstract
Vascular expandable devices and associated methods are disclosed herein. An expandable device can be implantable across an aneurysm in a blood vessel of a patient. The expandable device can include a generally tubular structure formed of a plurality of braided strands. Each of the plurality of strands can have a diameter that is 0.002 inches (0.0508 mm) or less, and each of at least some of the plurality of strands can have a diameter that is 0.0009 inches (0.02286 mm) or less. The device can be self-expandable from a compressed state to an expanded state, in which the expanded state diameter is at least 1.75 mm.
Claims24
An expandable device implantable across an aneurysm in a blood vessel of a patient, the expandable device comprising:
- a generally tubular structure formed of a plurality of braided strands, the tubular structure having a proximal end, a distal end, and a length between the proximal end and the distal end;
- each of the plurality of strands having a diameter that is 0.002 inches (0.0508 mm) or less, and each of at least some of the plurality of strands having a diameter that is 0.0009 inches (0.02286 mm) or less;
- and
- the expandable device having a compressed state and an expanded state, and being self-expandable from the compressed state to the expanded state, in which the expandable device has an expanded state diameter of at least 1.75 mm.
A system comprising:
- a core assembly;
- and
- a generally tubular structure disposed on the core assembly, wherein:
- the tubular structure is formed of a plurality of braided strands, and has a proximal end, a distal end, and a length between the proximal end and the distal end;
- each of the plurality of strands has a diameter that is 0.002 inches (0.0508 mm) or less, and each of at least some of the plurality of strands has a diameter that is 0.0009 inches (0.02286 mm) or less;
- and
- the tubular structure has a compressed state and an expanded state, and is self-expandable from the compressed state to the expanded state, in which the tubular structure has an expanded state diameter of at least 1.75 mm.
