Described here are devices, systems, and methods for providing remote traction to tissue. Generally, the systems may include a grasper and a delivery device configured to releasably couple to the grasper. The grasper may have a first jaw and a second jaw and a main body having a barrel portion. The barrel portion may have a lumen extending therethrough, and a portion of the delivery device may be advanced through the lumen to rotate one or both of the jaws. The delivery devices may include a handle, a shaft, and a distal engagement portion. The delivery devices may further include an actuation rod which may be advanced through a barrel portion of a grasper to actuate the grasper. In some instances, the delivery device may further include a locking sheath, wherein the locking sheath is configured to temporarily couple to a grasper.

1. A system for grasping tissue comprising: a grasper comprising a main body comprising a barrel portion having a lumen extending therethrough, a first jaw rotatably coupled to the main body, and a second jaw; anda delivery device comprising a handle, a distal engagement portion configured to releasably couple to the grasper, a shaft connecting the handle and the distal engagement portion, and an actuation rod,wherein the actuation rod is advanceable through the lumen to rotate the first jaw relative to the second jaw and the actuation rod is retractable through the lumen to decouple the grasper from the distal engagement portion; wherein the distal engagement portion comprises a coupling magnet; and wherein the coupling magnet is moveable relative to a longitudinal axis of the distal engagement portion between an advanced position and a retracted position. 2. The system of claim 1 wherein the grasper comprises a proximal arm connected to the first jaw, such that rotation of the proximal arm relative to main body rotates the first jaw away from the second jaw. 3. The system of claim 1 wherein at least a portion of the grasper comprises one or more of a metallic and magnetic material configured to be attracted to a magnetic field. 4. The system of claim 3 wherein the grasper comprises a ferromagnet. 5. The system of claim 4 wherein the grasper comprises one or more of stainless steel, iron, cobalt, nickel, neodymium iron boron, samarium cobalt, aluminum nickel cobalt alloy, ceramic ferrite, and alloys thereof. 6. A system for grasping tissue comprising: a grasper comprising a main body comprising a barrel portion having a lumen extending therethrough, a first jaw rotatably coupled to the main body, and a second jaw; anda delivery device comprising a handle, a distal engagement portion configured to releasably couple to the grasper, a shaft connecting the handle and the distal engagement portion, and an actuation rod,wherein the actuation rod is advanceable through the lumen to rotate the first jaw relative to the second jaw,wherein the delivery device comprises a locking sheath having an expandable distal end, wherein the delivery device is configured to expand the expandable distal portion from an unexpanded configuration to an expanded configuration in the lumen of the barrel portion to couple the locking sheath to the grasper. 7. The system of claim 6 wherein the locking sheath and the actuation rod are configured to engage using a friction fit. 8. The system of claim 6 wherein the locking sheath and the actuation rod are configured to engage by a mechanical interlock. 9. A system for grasping tissue comprising: a grasper comprising a main body comprising a barrel portion having a lumen extending therethrough, a first jaw rotatably coupled to the main body, and a second jaw;a delivery device comprising a handle, a distal engagement portion configured to releasably couple to the grasper, a shaft connecting the handle and the distal engagement portion, and an actuation rod, wherein the actuation rod is advanceable through the lumen to rotate the first jaw relative to the second jaw; anda trigger configured to releasably couple the delivery device to the grasper; wherein the distal engagement portion comprises a coupling magnet; and wherein the coupling magnet is moveable relative to a longitudinal axis of the distal engagement portion between an advanced position and a retracted position. 10. The system of claim 9 wherein a trigger configured to move between a first position, a second position, and a third position, wherein the first position is an intermediate position between the second position and the third position, wherein the grasper is configured to be in a closed configuration when the trigger is in the first position, wherein the grasper is configured to be in an open configuration when the trigger is in the second position, and wherein the delivery device is configured to be decoupled from the grasper when the trigger is in the third position configuration when the trigger is in the first position, wherein the grasper is configured to be in an open configuration when the trigger is in the second position, and wherein the delivery device is configured to be decoupled from the grasper when the trigger is in the third position.
