Patent attributes
A patch for interposing between an implantable device and a treatment site, such as to inhibit migration (e.g., lateral shifting) of the implantable device with respect to the treatment site without interfering with contact of the implantable device with the treatment site, and/or to reduce (and preferably inhibit or prevent) damage to tissue at the treatment site and/or movement of the anchor element (used to anchor the implantable device) with respect to the treatment site. The patch may extend continuously around the perimeter of the device, or discontinuously as more than one patch. The patch may be delivered on the implantable device to the treatment site, or separately delivered and deployed before the implantable device is delivered and deployed, the implantable device being implanted over the patch and the treatment site.
