Abstract
A magnet-assisted suture grasper for grasping a magnetic suture is provided. The magnet-assisted suture grasper includes a suture retrieval needle, a retriever body, a grasper wire, a grasper arm, and a grasper magnet. Translation of the retriever body within a needle lumen of the suture retrieval needle in a first direction causes the grasper arm to move from a first position to a second position, thereby exposing the grasper magnet from the needle lumen and allowing contact between the grasper magnet and a magnetic suture attracted thereto. Translation of the retriever body within the needle lumen in a second direction opposite the first direction causes the grasper arm to move from the second position to the first position, thereby sequestering the grasper magnet and grasping the magnetic suture within the needle lumen.
