DEVICES, SYSTEMS, AND METHODS FOR RESHAPING A HEART VALVE ANNULUS INCLUDING THE USE OF MAGNETIC TOOLS

摘要

Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize a bridge stop to secure the implant, and the methods of implantation employ various tools.

主权项

1. A method of treatment a human or veterinary patient involving two adjacent bodily structures comprising:
providing a first catheter having a first interior channel, the first catheter having a first orifice between said first interior channel and the exterior of the catheter, said first catheter having a first magnetically attracting tip, said first magnetically attracting tip comprising a ferromagnetic material, located in the length of said first catheter that includes said first orifice, said first magnetically attracting tip having a polarity parallel to said interior channel; providing a second catheter having a second interior channel, the second catheter having a second orifice between said second interior channel and the exterior of the second catheter through the side wall of said second catheter, said second catheter having a second magnetically attracting tip, said second magnetically attracting tip comprising a ferromagnetic material, located in the length of said catheter that includes said second orifice, said second magnetically attracting tip comprised of three magnetic sections, a first magnetic section, a middle magnetic section and a third magnetic section, said first and third magnetic sections having opposing polarity, and said middle magnetic section having its polarity oriented perpendicular to the polarity of said first and second section; locating said first catheter within a first body structure; locating said second catheter within a second body structure adjacent body structure; placing said first magnetically attracting tip within said first body structure adjacent said second magnetically attracting tip with a layer of tissue between said first magnetically and second magnetically attracting tips such that said first and second magnetically attracting tips align and magnetically couple to each other with first and second orifices opposed to each other but separated by the layer of tissue between them; and passing a piercing device through the first orifice, through the layer of tissue, and into the second orifice.
