    摘要: A clot retrieval device is disclosed to remove clot from a blood vessel. The device can include a collapsed configuration and an expanded configuration. The device can include an inner expandable body with a framework of struts. The device can include an outer expandable body with a framework of struts that at least partially radially surrounding the inner expandable body. A distal portion of the outer expandable body can extend in the deployed configuration towards the outer expandable body to a greater extent than the inner expandable body, closed cells of the distal portion distally tapering and being smaller than cells proximal thereof in the outer expandable body. The plurality of closed cells of the distal portion can include a pair of axially aligned smaller diamond shaped cells formed by struts of the distal portion and positioned along upper and lower regions of the distal portion.

    摘要: A clot retrieval device includes an inner expandable member and an outer expandable member, each formed from respective strut frameworks such that the outer expandable member has larger cell openings than the inner expandable member. The outer expandable member can have multiple discontinuous body segments spaced apart in relation to a longitudinal axis of the device. Adjacent discontinuous body segments can be joined by a pair of tapered connecting arms that are able to bend with a small radius of curvature compared to the body segments. Some or all of the body segments can include radiopaque markers positioned to illustrate a circumference of the respective body segment and slightly staggered in relation to a longitudinal axis of the device such that the markers nest when the device is collapsed for delivery.

    摘要: An introducer tool for use with a vascular entryway system and method. While a radially self-expanding distal section of an aspiration catheter is in a radially non-compressed state, an aspiration catheter is pre-assembled into a flared proximal section of the introducer tool. Together as a single unit, the introducer tool with the aspiration catheter pre-assembled therein is introduced into a hemostasis valve and a tapered guide sheath luer. The aspiration catheter is pushed through the introducer tool. While traversing the compressing section of the lumen of the shaft of the introducer tool and/or the tapered inner profile of a tapered guide sheath luer, the radially self-expanding distal section of the aspiration catheter is radially compressed to be receivable in a lumen of a guide sheath catheter. While the radially self-expanding distal section is radially compressed, the aspiration catheter is slid into the lumen of the guide sheath catheter.

    摘要: The disclosed technology includes a clot retrieval device being configured to retrieve a clot from a blood vessel and having a constrained delivery configuration and a clot engaging configuration. The device can include a first expandable framework having a first plurality of struts that form a first body and a second expandable framework having a second plurality of struts that form a second body upon the clot retrieval device transitioning from the constrained delivery configuration to the clot engaging configuration. In the clot engaging configuration, the first body can be configured to move from a first position to a second position in relation to the second body. Upon moving from the first position to the second position, the clot retrieval device can pinch the clot between the first body and the second body.

    摘要: A clot removal device comprising an outer cage, an inner cage concentrically positioned within the outer cage, a first elongated member in communication with the outer cage, and a second elongated member in communication with the inner cage. The first elongated member can be attached to a proximal end of the outer cage and configured to move the outer cage between delivery and expanded configurations. The second elongated member can be attached to a proximal end of the inner cage and configured to move the inner cage between delivery and expanded configurations.
