Abstract
Devices and methods for treatment of a patient's vasculature with some embodiments configured for delivery with a microcatheter for treatment of the cerebral vasculature of a patient. Some embodiments may include a permeable shell and inner structure configured to occlude blood flow therethrough.
Claims17
A device for implantation within a vascular defect or aneurysm, comprising:
- a self-expending resilient first layer including:
- a proximal end,
- a distal end,
- a longitudinal axis,
- a plurality of elongate filaments disposed in woven structure between the proximal end and distal end,
- the first layer being movable to a collapsed state configured for delivery within a microcatheter with the elongate filaments extending longitudinally from the proximal end to the distal end, the first layer being movable to an expanded state with a longitudinally shortened configuration relative to the collapsed state, first layer being formed as a continuous closed volume in the expanded state, the continuous closed volume formed by the elongate filaments defining a surface having a number of undulations.

An assembly comprising:
- a porous body including:
- a proximal end,
- a distal end,
- a plurality of elongate filaments disposed between the proximal end and distal end,
- the body being movable to a collapsed state configured for delivery within a microcatheter with the elongate filaments extending longitudinally from the proximal end to the distal end, the body being movable to an expanded state with a longitudinally shortened configuration relative to the collapsed state, the body being formed as a closed volume in the expanded state, wherein in the expanded state the body has a three-dimensional shape with a continuous outer surface such that edges of at least two portions of the body overlap each other.

An apparatus comprising:
- a body including;
- a proximal end,
- a distal end,
- a plurality of elongate filaments disposed between the proximal end and distal end,
- the body being movable to a collapsed state configured for delivery within a delivery device with the elongate filaments extending from the proximal end to the distal end, the body being movable to an expanded state with a longitudinally shortened configuration relative to the collapsed state, the body being formed as a closed volume in the expanded state, wherein in the expanded state the body has a three-dimensional shape with a continuous outer surface such that edges of at least two portions of the body overlap each other, the continuous outer surface having plural undulations.
