Abstract
The present invention relates to an instrument and method for passing a medical implement through tissue with magnetic forces. The implement can be an implant, either permanent or temporary, and is provided with a magnetic component. A magnetic field is established and the magnetic component and/or magnetic field is manipulated to drive the implant through tissue. Alternatively, the instrument itself is the implement and includes at least one magnetic element so that a magnetic field established by an external magnetic generator drives the instrument through tissue. In another embodiment, the instrument includes two magnetic elements that are moveable with respect to one another and interaction between the magnetic elements drives the instrument through the tissue. Examples of applications of the present invention include a suture passer and a tissue anchor.
