Abstract: Described here are systems, devices, and methods for providing remote manipulation or traction to tissue using one or more graspers, delivery devices, and magnetic control assemblies. The graspers may be configured for insertion into the patient during a minimally-invasive procedure, such as a laparoscopic operation. The graspers may be configured to releasably connect to tissue. In some embodiments, the grasper may comprise a clip, a clamp, a suction device, a coil, or the like, and may be configured to connect to any suitable tissue. Delivery devices may be configured to releasably engage a grasper to deliver the grasper, remove it from the patient, or reposition it. The delivery devices may additionally be configured to actuate the grasper to attach it to tissue and/or detach it from tissue. The magnetic control elements may be configured to be positioned externally of the body to move, reposition, and/or hold the grasper.

Abstract: Described here are devices, systems, and methods for moving and/or supporting an internal organ or other tissue, such as during minimally-invasive surgery. Generally, a system for moving and/or supporting tissue may comprise a magnetic control component and a retractor having at least one magnetic portion. The retractor may have a first low-profile configuration for passing through an incision into a surgical site within a patient and a second expansive configuration for engaging tissue. The magnetic control component may be placed over the surgical site external to the patient and generate a magnetic field to manipulate the retractor and engaged tissue.

Abstract: Described here are devices and systems for applying an adjustable strength magnetic field to a magnetic device located within the body. In some variations, the devices may comprise a force modulation device comprising an adjustable shielding device. In other variations, the devices may comprise a force modulation device comprising a distance adjustment device. In some variations, the force modulation device may be adjusted by an automated control mechanism based on information from a sensor in the magnetic device.
