A first end of a wire is transluminally penetrated through tissue at a first cardiovascular site of a subject. A capture device is transluminally advanced into the subject, and is used to capture the first end of the wire and pull the first end of the wire away from the first cardiovascular site. From the first end of the wire, a first anchor is tracked along the wire, and is then anchored to the tissue at the first cardiovascular site. A second anchor is anchored to tissue at a second cardiovascular site. Subsequently, the first and second cardiovascular sites are drawn together by applying tension between the first and second anchors. Other embodiments are also described.

Devices and methods for percutaneous tricuspid valve repair

A system is transluminally advanced into a subject. A first portion of the system is positioned adjacent a cardiovascular tissue of the subject, the system including wires disposed at the first portion. The first portion is stabilized at the cardiovascular tissue by positioning a distal portion of the system against a cardiovascular wall of the subject. While the distal portion of the system remains against the cardiovascular wall, the wires are induced to bow laterally such that the wires press against the cardiovascular tissue. While the wires remain pressed against the cardiovascular tissue, the shape of the wires is radiographically imaged. While (i) the first portion remains stabilized, and (ii) the wires remain pressed against the cardiovascular tissue, at least a portion of the system is transluminally implanted at the cardiovascular tissue, facilitated by the imaging. Other embodiments are also described.

Devices and methods for locating and implanting tissue anchors at mitral valve commissure

A first anchor is anchored inside a coronary sinus of a heart of a subject. A second anchor can be driven into a tricuspid annulus of the heart. A distal portion of the second anchor can be disposed adjacent and parallel to a center portion of the second anchor. The second anchor can be seated against a surface of the annulus, for example, such that (i) the distal portion is disposed perpendicular to the center portion, (ii) the center portion extends through the annulus, and (iii) a proximal portion of the second anchor is disposed in the atrium. A distance between the first and second anchors can be reduced by applying tension to a tensioning member coupled to the first anchor and the proximal portion of the second anchor. Other embodiments are also described.

System and method for reducing tricuspid regurgitation

A first end of a wire is transluminally advanced to a location adjacent an atrium of a heart of a subject, while a second end of the wire remains disposed outside of the subject. From the location, the first end of the wire is penetrated through tissue into the atrium. A capture device is transluminally advanced into the atrium. Using the capture device, the first end of the wire is captured and pulled out of the subject. From the first end of the wire, a first anchor is tracked along the wire into the atrium, and is anchored to an annulus of a valve of the heart. A second anchor is advanced into the atrium, and is anchored to the annulus. Subsequently, the annulus is reshaped by applying tension between the first and second anchors.

A system is transluminally advanced into the heart of a subject. A first portion of the system is positioned through a native valve of the heart, the system including wires disposed at the first portion. The first portion is stabilized at the native valve by positioning a distal portion of the system within a blood vessel of the subject. While the distal portion of the system remains within the blood vessel, the wires are induced to bow laterally such that the wires press against the native valve. While the wires remain pressed against the native valve, the shape of the wires is radiographically imaged. An anchor is transluminally anchored to tissue of the native valve, facilitated by the imaging. Other embodiments are also described.

The present teachings provide systems, devices, and methods for reshaping the heart and reducing valve regurgitation. A device can be positioned proximate the heart and have a delivery profile and an inflated profile. The device can have a primary cavity and a secondary cavity, and an adhesive inside the secondary cavity. An injectable medium can be injected to the primary cavity of the device. As the primary cavity is filled, the adhesive is forced out of the secondary cavity to adhere the device. The inflated device can exert pressure on the heart, change the shape of a valve annulus, and allow a better coaptation of the valve leaflets.

System and method for reshaping heart

Systems, devices and methods for securing tissue including the annulus of a mitral valve. The systems, devices and methods may employ catheter based techniques and devices to plicate tissue and perform an annuloplasty.

Tissue anchors, systems and methods, and devices

The present teachings provide methods for resizing, reducing, and/or closing an atrial appendage. A delivery catheter is percutaneously advanced to the atrial appendage. At least two tissue anchors are implanted in tissue of the heart. Both tissue anchors are pulled together so that the atrial appendage is resized, reduced, and/or closed. This closure method and system could be used alone in closing the atrial appendage. This closure method and system could also be used in addition to other treatment mechanisms.

Method and system for closing left atrial appendage

An aspect of the present teachings includes a method of percutaneously treating a paravalvular leakage. In a preferred embodiment, the method includes providing an anchor having an elongate anchor member and a tensioning member, positioning the anchor through a paravalvular leakage, deploying the anchor wherein at least a part of the distal portion of the elongate anchor member is on one side of the paravalvular leakage, and applying tension to the tensioning member so that at least a part of the distal portion of the elongate anchor member transitions from the elongate configuration to the shortened configuration. Another aspect of the present teachings includes a device that can be used in a method of percutaneously treating a paravalvular leakage.

Devices for treating paravalvular leakage and methods use thereof

The present teachings provide devices and methods of locating a mitral valve commissure, and implanting tissue anchors at or near the mitral valve commissure. Specifically, one aspect of the present teachings provides devices and methods for locating a mitral valve commissure percutaneously and allowing a guide wire to be placed across a mitral annulus at the mitral valve commissure. Another aspect of the present teachings provides methods for deploying a tissue anchor across a mitral annulus at a mitral valve commissure, including near the Por Pregions of the posterior mitral annulus. Another aspect of the present teachings further provides methods of plicating a mitral annulus between two or more tissue anchors.

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, another aspect of the present teachings provides devices and methods of placing a wire across the tricuspid annulus at such an identified location, another aspect of the present teachings provides devices and methods of deploying a tissue anchor across such an identified location, and yet another aspect of the present teachings provides devices and methods of applying tension to two or more of such tissue anchors and reducing the circumference of the tricuspid annulus. As a result, a regurgitation jet is reduced or eliminated.

The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices each includes a vascular anchor, an annulus anchor, and at least one tensioning member connecting with the vascular anchor or the annulus anchor. Another aspect of the present teachings provides methods of deploying a vascular anchor at a first treatment location inside the coronary sinus, and deploying an annulus anchor at a second treatment location across the tricuspid annulus. When both the anchors are pulled towards each other, the portion of the annulus between the two anchors is plicated, which improves the coaptation of the tricuspid valve leaflets.

The present teachings provide devices and methods of reshaping the right heart and reducing tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides an inflatable device to be deployed in the space between the sternum and the right heart. An injectable medium is injected to the cavity of the device. Once the device is filled, the device is detached from the delivery system, and released inside the body. The inflated device exerts pressure to the right heart, changes the shape of the tricuspid annulus, and allows a better coaptation of the tricuspid leaflets.

System and method for reshaping right heart

The present teachings provide methods for resizing, reducing, and closing left atrial appendage. Specifically, a percutaneous trans-septal access is first established from outside the body to a patient's LAA. At least two tissue anchors are then implanted inside the LAA chamber and along the tissue wall. At least one anchor is implanted near the opening of the LAA camber. Both tissue anchors are pulled together so that the wall of the LAA chamber collapse. The LAA chamber is therefore resized, reduced, and/or closed off completely. This closure method and system could be used alone in closing LAA chamber. This closure method and system could also be used in addition to other treatment mechanisms, such as filling the LAA chamber with space-filling material, then closing off its opening.
