Patent number: 11937837Abstract: Designs are disclosed for devices capable of removing both firm and soft clots from body vessels that can have dual layers where an inner expandable body of cells runs within an outer expandable cage of cells. The designs can feature a constrained delivery configuration and an expanded deployed configuration. An outer cage can have wide opening struts to allow for clot integration into the device. Both the inner body and outer cage can be configured with shapes to pinch a clot in addition to embedding in it. The devices can also be capable of having a portion of the outer cage fold and invert proximally after engaging with a target clot to internalize it. These factors can increase the device's ability to capture clots of all compositions, allowing for safer and more efficient flow restoration.Type: GrantFiled: December 29, 2020Date of Patent: March 26, 2024Assignee: NEURAVI LIMITEDInventor: Declan Lee
