Complex wire formed devices
First Claim

1. A medical device for delivery through a catheter, the medical device comprising:
- a main bundle comprising a group of wires having a first end extending through the catheter and a second end;
where the main bundle of wires diverge at the second end to form a first shaped section, the first shaped section further comprises an expanded profile and a reduced profile for delivery through the catheter;
a plurality of individual subsets of wires each diverging from the first shaped section to form a second shaped section;
where the individual subsets of wires converge to form a third Shaped section, where the third shaped section comprises an expanded profile and a reduced profile for delivery through the catheter, where the third shaped section is self expanding to assume the expanded profile upon deployment from the catheter; and
where the convergence and divergence of wires occurs without junctions between wires and where the third shaped section is configured to assume the expanded profile independently of the first shaped section.

Abstract
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.

30. An intravascular apparatus for deployment in a vessel comprising:
-
a plurality of wires grouped into a main bundle, where at least a first portion of the plurality of wires diverge from the main bundle to form a first shape; a plurality of subsets of wires diverging from the first shape and extending normally from the first shape; a second shape thrilled by the convergence of the plurality of subsets of wires; where the first shape has a first expanded profile when unconstrained, such that on deployment in the vessel the first shape expands towards the first expanded profile; where the second shape is collapsible to fit within a microcatheter and has a second expanded profile when unconstrained, such that on deployment in the vessel the second shape expands towards the second expanded profile; and where the plurality of subsets of wires extending between the first and second shapes, and are spaced apart such that spacing the first and second shapes causes the plurality of subsets to move towards a wall of the vessel and where the second shape is configured to assume the second expanded profile independently of the first shape. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57)
