Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those 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. The implant is secured to tissue with anchors that can rotate without axial advancement to engage tissue while drawing the implant closer to the tissue. Collars are used to decrease the angle between struts of a frame to contract the implant. The implants can include a rotatable shaft, such as a threaded shaft, located internally to an axially translatable collar. Rotation of the shaft transmits force to the collar to cause the collar to translate axially, closing the angle of adjacent struts and decreasing the width of the implant and thus of the annulus. The implants can be delivered, secured and contracted via a catheter. The implants are repositionable and retrievable via catheter.

Abstract: Disclosed is a novel filter and delivery means. The device described within will not interfere with standard practice and tools used during standard surgical procedures and tools such as cannulas, clamps or dissection instruments including valve replacement sizing gages or other surgical procedures where the patient must be put on a heart-lung machine cross-clamping the aorta.

Abstract: Excessive dilation of the annulus of a mitral valve may lead to regurgitation of blood during ventricular contraction. This regurgitation may lead to a reduction in cardiac output. Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The implant may then contract to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the mitral valve and lessening any of the associated symptoms including mitral regurgitation.

Abstract: Features for a heart valve device are described. The device may include a frame with anchors configured to secure the device to tissue. The frame may include a flared end or skirt for additional securement of the implanted device. The device may include a seal such as a barrier and/or cuff for preventing leakage. The device may contract for endovascular delivery of the device to the heart and expand for securement within the heart, such as the within the native mitral valve annulus. The device may include a replacement valve. The valve may have leaflets configured to re-direct blood flow along a primary flow axis.

Abstract: Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the risk of injury to the patient.

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: Systems, devices and methods for resizing a valve annulus are described. An implant is delivered proximate a mitral valve, the implant comprising a tubular body and a plurality of piercing helical anchors, the tubular body comprising an proximal diameter and a distal diameter. Tissue proximate the mitral valve is engaged by rotating the plurality of anchors with corresponding rotational drivers. The tubular body may be transitioned from a first structural configuration having the proximal diameter smaller than the distal diameter to a second structural configuration having the proximal diameter larger than the distal diameter.
