Abstract
A method for closing an aneurysm in a blood vessel may utilize a staple having two or more tines, where those tines are oriented at least partially in the proximal direction. The method may include advancing the staple through the vasculature to a location within the aneurysm, plastically deforming the staple to a splayed configuration, penetrating at least one said tine of the staple in that splayed configuration into tissue in proximity to the neck of the aneurysm, and plastically deforming the staple to a closed configuration to close the aneurysm.
Claims7
A method for closing an aneurysm, the aneurysm having a neck connected to a blood vessel, comprising:
- providing a staple having a plurality of tines, said tines oriented at least partially in the proximal direction;
- advancing said staple through the vasculature to a location within the aneurysm;
- plastically deforming said staple to a splayed configuration;
- penetrating at least one said tine of said staple in said splayed configuration into tissue in proximity to the neck of the aneurysm
- plastically deforming said staple to a closed configuration, whereby the neck of the aneurysm is substantially closed;
- and providing an end effector, wherein said end effector holds said staple;
- and wherein said plastically deforming said staple to a splayed configuration and said plastically deforming said staple to a closed configuration are performed by said end effector.
