PROBLEM TO BE SOLVED: To provide improved structures for removing obstructions from body lumens.SOLUTION: Such devices have applicability in through-out the body, including clearing of blockages within the vasculature, by addressing the factional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen. A medical device can include a capturing surface that is configured to generate a spring force against the translating surface when a proximal force applied by the main bundle of wires compresses the capturing surface against the translating surface when encountering resistance from the obstruction, where the capturing surface is configured to have a sufficient axial stiffness to direct the spring force and proximal force to the open proximal end as the open proximal end engages the obstruction where the capturing surface is also sufficiently flexible to conform to a shape of the vessel. |
