Abstract
Abstract The three dimensional device is adapted to be inserted into a portion of a vasculature for occluding the portion of the vasculature for use in interventional therapy and vascular surgery. The device is formed from a multi-stranded microcable having a plurality of flexible strands of a shape memory material and at least one radiopaque strand. The flexible strands in a multi-stranded micro-cable of the device can be helically wound, or can be configured as parallel, longitudinal strands, and can also be formed to have a secondary, three dimensional therapeutic configuration, such as helical, conical, spherical, or other geometric shapes. The strands can be made of a shape memory nickel titanium alloy, that is highly flexible at a temperature appropriate for introduction into the body via a catheter, and that after placement will take on the therapeutic shape. The device can also include a therapeutic agent, and can be bundled by an outer cover to constrain the strands of the micro-cable about a longitudinal axis to produce a composite banded cable.
