Title:

血管から閉塞性血餅を除去するための血餅回収デバイス

Document Type and Number:

Japanese Patent JP7389159

Kind Code:

B2

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.
