  • Publication number: 20220022854
    Abstract: A device for treating a left atrial appendage, including an implant having a contact member configured to engage an inside tissue surface of the left atrial appendage and configured to rotate in at least a first direction from a first position to at least a second position so as to twist the left atrial appendage when the contact member is engaged with an inside tissue surface of the left atrial appendage. Some embodiments can also include a securing element configured to move between a first position in which the securing element is decoupled from the contact member and a second position in which the securing element is coupled with the contact member.
