LAPAROSCOPIC GRASPERS AND SYSTEMS THEREFOR

摘要

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.

主权项

1. A system for manipulating tissue, comprising:
a grasper configured to be attached to tissue in a body of a patient; a delivery device configured to releasably engage the grasper and to actuate the grasper between a first configuration and a second configuration; and a magnetic control assembly comprising a magnet configured to generate a magnetic field and to apply a magnetic force to the grasper.
