An insertion device that allows gaining access to the left ventricle of the heart, via the tissue forming the wall of the right ventricle and via the ventricular septum, which includes a tubular shaft with a lumen extending there through, the shaft comprising distal, proximal and central sections, whereby the distal and proximal sections are disc-shaped extended thus forming each a double disc and whereby the central section links the distally placed double disc with the proximally placed double disc and whereby pressure valves are fixed inside the shaft preferably on its distal and proximal end.

Devices and related methods of use are provided for improving heart function. In one embodiment of the present disclosure, a device includes a ring-like structure configured to be secured to a heart valve; at least one elongate member extending from the ring-like structure, wherein an end of the elongate member is configured to be secured to heart geometry other than a heart valve; and an adjustment mechanism for simultaneously altering a dimension of the ring-like structure and a length of the elongate member.

Described is a collapsible atrial cage for percutaneous delivery and implantation of an atrioventricular valve within an atrium of the heart. The atrial cage includes an atrial portion and a ventricular portion. The ventricular portion is attached with and separated from the atrial portion by a valve juncture portion. Notably, the cage includes at least one interlock shaped to lock with and secure an atrioventricular valve proximate the valve juncture portion. Thus, when deployed and expanded, the atrioventricular valve is secured at the atrioventricular juncture.

Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.

Described herein are implant loading and delivery systems for treating heart failure. An implant loading system may include a funnel having a flared first end and a second end, such that the flared first end is configured for receiving and collapsing the expandable implant, and a sleeve removably coupled to the second end of the funnel and configured to transfer the expandable implant to a guide catheter. The expandable device may have a foot for contacting a first interior wall portion of a heart, a support frame including a plurality of radially expandable struts, and a membrane coupled to the support frame. The expandable device may be coupled to a delivery catheter. An expansion member coupled to a distal end of the delivery catheter may apply pressure to the support frame of the expandable device to move the expandable device from a collapsed configuration to an expanded deployed configuration.

A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.

The present invention relates to a medical chamber system (700) for implantation in the chest of a patient to support the heart activity, preferably by displacing the heart apex (105), comprising at least a first chamber (702) for arrangement inside the heart sac (300) and a second chamber (701) for arrangement outside the heart sac (300), wherein the chambers (701, 702) comprise at least one connection portion or connection channel (703) which connects the two chambers (701, 702) to each other, the chambers (701, 702) and the connection channel (703) are further embodied to be filled with fluid (705) and, preferably in the implanted state, to be arranged such that the heart activity acts on the first chamber (702) and that the second chamber (701) acts as a volume storage and/or energy storage for the fluid (705). Furthermore, the present invention relates to an introduction system for a medical chamber system (700) and to a kit, encompassing a medical chamber system (700) and an introduction system.

A heart valve stent having a section with a heart valve implant and several proximally disposed tissue anchors, also comprising a plurality of anchoring threats, each with a proximate end fastened to the stent or valve and a distal end attached to tissue within a heart chamber to provide tension between the heart chamber tissue and the stent.

Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet.

Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilise an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.
