Abstract: Multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a multi-filter blood filtering system captures and removes particulates dislodge or generated during a surgical procedure and circulating in a patient's vasculature. In some embodiments a dual filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.

Abstract: Methods related to delivery of various heart valve implants are described. The implant may be delivered using an ultrasound imaging delivery system. The ultrasound imaging delivery system may be used to deliver a variety of different devices, including mitral valve reshaping devices, mitral valve replacement valves, and others. A deployment catheter carrying an implant having a tissue anchor is advanced to a deployment site in a heart. An imaging element is positioned adjacent the implant and a relationship between the tissue anchor and an anatomical landmark in the heart is visualized. The implant is then attached by driving the tissue anchor into tissue in the heart.

Abstract: Solutions for reducing irritation and/or trauma which may result upon contact of an implanted implantable device with tissue surrounding or adjacent to the implantable device. Various embodiments include features which allow a tangential or otherwise atraumatic contact of the implantable device with the tissue, in contrast with a sharper contact which may occur with prior art implantable devices. The broad principles are applicable to annuloplasty devices, and have other broader applications as well.
