Clot retrieval device for removing occlusive clot from a blood vessel
First Claim
1. A clot retrieval device for removing an occlusive clot from a blood vessel comprising:
- a planar clot engaging element having a constrained delivery configuration and an expanded deployed configuration, the clot engaging element having a mesh between a plurality of longitudinally extending undulating edges, the clot engaging element comprising;
a first peripheral portion comprising a peak,a second peripheral portion extended distally from the first peripheral portion, the second peripheral portion comprising a peak, anda clot engaging section between the peaks of the first and second peripheral portions,wherein, in the expanded configuration, the peaks of the peripheral portions are laterally spaced-apart and when under tension, configured to pinch the occlusive clot from the blood vessel between the peaks of the peripheral portions in the clot engaging section.

Abstract
A clot retrieval device for removal of occlusive clot from a blood vessel comprises a clot engaging element 700 having a constrained delivery configuration and an expanded deployed configuration. In the expanded configuration peripheral portions are laterally spaced-apart and the clot engaging section 700 extends between the peripheral portions. The device 700 may have two superimposed wave patterns provided by a large amplitude curve 723 and shorter pitch sinusoidal patterns 721, 722. A wave shape varies the contact pressure between a clot and the device along the length of the device, reducing the compression of the clot by the device at some locations. The device can elongate when placed under tension which aids elongation of the clot during dislodgement.
