Abstract:
1. A tethered coil device adapted for treatment of a body lumen, comprising: a coiled member formed from a plurality of first shape coil segments alternatingly longitudinally connected with a plurality of second shape coil segments, the first shape coil segments being formed from a plurality of first shape coil elements longitudinally connected together and having an inner lumen and a first cross sectional area, and the second shape coil segments being formed from a plurality of second shape coil elements longitudinally connected together and longitudinally connected with said plurality of first coil elements, said second shape coil segments having an inner lumen and a second cross sectional area that is less than the first cross sectional area, the coiled member having a proximal end and a distal end, a first generally linear configuration, and a secondary complex three dimensional configuration; and a tether including a distal tether portion, a proximal tether portion, and an intermediate tether portion therebetween; the distal tether portion being connected with the coiled member of the device at an attachment point, and the intermediate tether portion being slidingly disposed generally longitudinally inside the inner lumen of at least one of said plurality of first shape coil segments and outside the inner lumen of at least one of said plurality of second shape coil segments; the proximal tether portion extending proximally beyond the proximal end of the coiled member and adapted for application of a proximal longitudinal force, wherein application of the proximal longitudinal force changes a shape of the coiled member from the first generally linear configuration to the secondary complex three dimensional configuration.
