    摘要: A clot removal assembly for removing a clot from a vessel that includes a delivery catheter, a clot retrieval device, and a valve assembly is presented herein. In some examples, the clot retrieval device can include a cage structure and a shaft, and the cage structure can be configured to pinch a clot. A portion of the shaft extends through the delivery catheter. In some examples, the valve assembly can include a distal valve, a main body portion, a distal body portion, and a moveable head shell. The distal valve can be configured to engage the proximal region of the delivery catheter. In some examples, the distal body portion can include a plurality of grooves, and the moveable head can be configured to ratchet proximally over the plurality of grooves to thereby maintain tension on the shaft.

    摘要: A nested mechanical thrombectomy assembly deliverable as a single assembled unit that includes an outermost mechanical thrombectomy device and at least one inner mechanical thrombectomy device, each mechanical thrombectomy device being actuatable from a radially compressed state to a radially expanded state. While in the radially compressed state, the at least one inner mechanical thrombectomy device is disposed in the inner channel of the outermost mechanical thrombectomy device. Each of the outermost mechanical thrombectomy device and the at least one inner mechanical thrombectomy device is actuatable/deployable independently of one another.

    摘要: A clot removal device can include a caged portion which can include a distal end; a proximal end; an inner cage having a network of inner struts; and an outer cage having a network of outer struts. The inner cage and the outer cage can include a delivery configuration within a microcatheter and a deployed configuration distal of the microcatheter operable to retrieve at least a portion of the clot. The device can include a distal pinching portion located proximate the distal end of the caged portion, and a proximal pinching portion located proximate the proximal end of the caged portion, each pinching portion can include at least one pinching cell can include a collapsed state and an expanded state distal of the microcatheter operable to tweeze at least a portion of the clot.

    摘要: A clot removal assembly that includes a delivery microcatheter, a cage structure configured to transform between a delivery configuration and an expanded pinching configuration, and a shaft in communication with the cage structure and substantially disposed within the delivery microcatheter is presented herein. The catheter includes a distal portion including an elongate radiopaque indicator, and a proximal portion, and the elongate radiopaque indicator is configured to transform between a substantially straight non-indicating state and a substantially wavy indicating state responsive to an impingement of the cage structure on the delivery microcatheter.
