Patent number: 11751965Abstract: Devices, systems, and methods for providing remote traction to tissue may include a grasper and a control element. The grasper may have a first jaw, a second jaw, a main body, and a first magnetic element. The control element may include a second magnetic element. The first and second magnetic elements may attract the grasper to the control element such that the grasper is oriented parallel, perpendicularly, or at an angle between parallel and perpendicular with respect to the control element and/or a body. In some instances, the grasper may include first and second magnetic elements and the control element may include third and fourth magnetic elements.Type: GrantFiled: January 28, 2021Date of Patent: September 12, 2023Assignee: LEVITA MAGNETICS INTERNATIONAL CORP.Inventors: Alberto Rodriguez-Navarro, Bryan Loomas

Patent number: 11730476Abstract: 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.Type: GrantFiled: January 17, 2020Date of Patent: August 22, 2023Assignee: LEVITA MAGNETICS INTERNATIONAL CORP.Inventors: Alberto Rodriguez-Navarro, Mariel Fabro, Archana Nair, Olgy Datto

Patent number: 11583354Abstract: 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.Type: GrantFiled: October 9, 2017Date of Patent: February 21, 2023Assignee: LEVITA MAGNETICS INTERNATIONAL CORP.Inventors: Alberto Rodriguez-Navarro, Mariel Fabro, Archana Nair, Olgy Datto, Ruth Beeby, Bryan Loomas

Patent number: 11357525Abstract: 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.Type: GrantFiled: October 2, 2018Date of Patent: June 14, 2022Assignee: LEVITA MAGNETICS INTERNATIONAL CORP.Inventors: Alberto Rodriguez-Navarro, Ruth Beeby, Steve Brunell, Mariel Fabro
