Complex wire formed devices
The devices and methods described herein relate to jointless construction of complex structures. Such devices have applicability in through-out the body, including clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.
1. A medical device for delivery through a catheter, the medical device comprising device comprising:
a first main bundle comprised of a plurality of wires;
a first shape formed by a divergence of the plurality of wires into a plurality of individual first subsets of wires, and where each first subset of wires diverges to form a network of wires,
where the network of wires converges to form a plurality of individual second subset of wires, and where each second subset of wires converges to form a second main bundle;
where a region of the device from the first shape to the second shape forms a self expanding basket structure having no joints that is configured to assume the expanded profile independently of the first shaped section; and
where the first and second shape each form a three dimensional structure.
2. The apparatus of claim 1 , where the network of wires comprise individual single wires.
3. The apparatus of claim 1 , where the first shape comprises a shape selected from the group consisting of a circle, an arcuate shape, a partial circular shape, a loop, an oval, a square, a rectangle, a polygon, an overlapping loop, a pair of semi-circles, a flower shape, and a Figure 8.
4. The apparatus of claim 1 , where the second shape comprises a shape selected from the group consisting of a circle, an arcuate shape, a partial circular shape, a loop, an oval, a square, a rectangle, a polygon, an overlapping loop, a pair of semi-circles, a flower shape, and a Figure 8.
5. The medical device of claim 1 , where the first shape is rotatable relative to the second shape, such that upon rotation the network of individual wires forms a mesh or helical pattern.
6. The apparatus of claim 1 , where each transition between each shape is jointless.
7. The apparatus of claim 1 , where each individual single wire comprises a plurality of filaments.
8. The apparatus of claim 1 , where the first main bundle and the second main bundle converge.
9. The apparatus of claim 1 , where main bundle of wires includes at least a first wire and a second wire where the first and second wire each has different characteristics.
10. The apparatus of claim 9 , where the characteristics are selected from a group consisting of material, cross-sectional shape, and cross-sectional size.
11. The apparatus of claim 9 , where the characteristics are selected from a group consisting of brittleness, ductility, elasticity, hardness, malleability, plasticity, strength, and toughness.
