Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium, through the mitral valve, and into the left ventricle. A ventricular anchor is deployed from the catheter and into a wall of the left ventricle, leaving a ventricular suture attached to the ventricular anchor and extending proximally through the catheter. A leaflet anchor is deployed to secure a mitral valve leaflet to a leaflet suture, with the leaflet suture extending proximally through the catheter. The leaflet suture is secured to the ventricular suture to limit a range of travel of the leaflet in the direction of the left atrium. Also disclosed is an assembled in situ mitral valve leaflet restraint, having a neo papillary muscle and a neo chordae tendinea.

Abstract: This disclosure includes apparatuses and techniques to access the right ventricle via trans-femoral vein threading a catheter or catheters to the apex or bottom of the right ventricle. Piercing through the venous or right side of the heart in the interventricular septal wall to access the left ventricle a catheter can be passed to turn upward pointing to the mitral valve. From this access point in the left ventricle the flail mitral leaflet can be sutured and tethered pulling it back into position and reattached with a grounding anchor in the right ventricle or imbedding the anchor into the septal wall. The interventricular septal wall crossing technique could include the passing of a coaxial catheter through the first access catheter where the first access catheter could act as a guide to direct the internal or second coaxial catheter toward the flail mitral leaflet.

Abstract: Various devices, apparatuses, and methods for transseptal puncture and crossing are disclosed herein. A transseptal puncture and crossing device can include novel puncture member having a crossing coil mated to a body portion to be able to both cross a tissue and allow a wire or guard be inserted through the puncture member. Though not required, the puncture member can have one or more of novel features, including a tapered coil portion, a transition cutter, a gripper coil portion, an atraumatic guard, and a shaped cutting wire. Methods for transseptal punctures and crossing include adding rotation, oscillation and/or ultrasound to a transseptal puncture device.

Abstract: A system for treating a left atrial appendage, including a delivery catheter and an implant having a contact member configured to engage an inside tissue surface of the left atrial appendage and to rotate in at least a first direction from a first position to at least a second position so as to twist the left atrial appendage when the contact member is engaged with an inside tissue surface of the left atrial appendage. Some arrangements of the system include a support stand for supporting the delivery catheter during a procedure. Some arrangements of the implant include a securing element configured to engage the tissue of the left atrial appendage that has twisted.

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: Disclosed are embodiments of a method for occluding a left atrial appendage (LAA) and other cavities or openings within a body. Some embodiments of the method can include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.

Abstract: An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.
