  • Publication number: 20200323528
    Abstract: A system for excising an implanted clip approximating opposed valve leaflets in a heart valve includes a capture catheter configured to be introduced proximate the valve leaflets on one side of the clip, a transfer catheter configured to be introduced proximate the valve leaflets on another side of the clip, and a cutting tool configured to be deployed between the capture and transfer catheters and to be engaged against tissue of at least one of the valve leaflets and to excise the clip. A removal catheter may optionally be used to remove the clip from the heart.

  • Publication number: 20200205966
    Abstract: Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle.

  • Patent number: 9597514
    Abstract: Embodiments of the present invention generally relate to epicardial heart rhythm management. In some embodiments a method is provided for managing heart rhythm by implanting a pa device within the pericardial space of a patient. In some embodiments, an implantable device is provided for pacing the epicardial surface of a patient. The device may include a first module coupled to a second module by a tether. The first and second modules may be selectively placed for bi-ventricular pacing or for dual chamber pacing in some embodiments. Optionally the modules may be separate and may wirelessly communicate with one another and may also communicate with a heart stimulation device programmer. Optionally, a plurality of devices may be implanted in the pericardial space. A delivery device for delivering the implantable device to the pericardial space is also provided. Further embodiments provide implant retrieval devices and methods.

  • Patent number: 8308765
    Abstract: Apparatus and methods for positioning and securing anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism either within the anchor itself of positioned proximally of the anchor may allow for the uni-directional translation while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This unidirectional anchor locking mechanism facilitates the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.
