Abstract: An illustrative mechanical thrombectomy system may comprise an outer catheter extending from a proximal end to a distal end and defining a first lumen extending therethrough and an inner sheath extending from a proximal end to a distal end and defining a second lumen extending therethrough. The inner sheath may be slidably disposed within the first lumen of the outer catheter. An inner shaft may be slidably disposed within the second lumen of the inner sheath and an expandable anchor mechanism may be coupled to the distal end region of the inner shaft. The expandable anchor mechanism may be configured to move between a collapsed delivery configuration and an expanded configuration.

Abstract: Systems, devices, and methods for closing a large bore access site are disclosed. An example system may include a delivery catheter and a closure device releasably coupled to the delivery catheter. The closure device may include an expandable frame and a patch secured to the expandable frame. The closure device may be configured to shift between a delivery configuration and an expanded configuration. The closure device may be configured to be delivered by the delivery catheter through a blood vessel to a position adjacent to a large bore opening formed in the blood vessel while in the delivery configuration and then shifted to the expanded configuration within the blood vessel so that the patch engages and covers the large bore opening.
