  • Patent number: 10682132
    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.

  • Patent number: 10624618
    Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.
