Abstract
An embolectomy device includes a pair of elongate spine members extending in a substantially parallel configuration along a longitudinal axis of the device, a first plurality of clot engaging structures having first ends attached to a first one of the spine members and second ends attached to other one of the spine members, and a second plurality of clot engaging structures having first and second ends attached to the respective first and second spine members offset 180° from the first plurality of attached clot engaging structures, such that, when the embolectomy device is unsheathed within in a blood vessel alongside a clot, one of the first and second plurality of the clot engaging structures contact and compress against a wall of the blood vessel to provide a biasing force to facilitate engagement of the other one of the first and second plurality of the clot engaging structures with the clot.
