Methods of minimally-invasively treating mitral valve regurgitation. The methods include advancing an intraluminal cardiac device in a collapsed configuration into a coronary sinus, retracting a catheter proximally within the coronary sinus to cause a first expandable anchor of the device to self-expand within the coronary sinus, retracting the catheter proximally within the coronary sinus to expose a connecting member of the device, pulling proximally on the cardiac device to reshape mitral valve tissue to reduce mitral valve regurgitation, retracting the catheter proximally within the coronary sinus to cause a second expandable anchor of the device to self-expand within the coronary sinus, and releasing the intraluminal cardiac device from a delivery device.

Mitral valve annuloplasty device with twisted anchor

In one embodiment, the present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. Such tissue shaping device can include an expandable proximal anchor; a proximal anchor lock adapted to lock the proximal anchor in an expanded configuration; an expandable distal anchor; a distal anchor lock adapted to lock the distal anchor in an expanded configuration; and a connector disposed between the proximal anchor and the distal anchor, the connector having a substantially non-circular cross-section.

Tissue shaping device

An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.

Device and method for modifying the shape of a body organ

The present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. The device comprises a first anchor and a second anchor adapted to be deployed by a catheter to engage a vessel wall while the first anchor is adapted to resist the compression of a first part of the first anchor and resist the expansion of a second part of the first anchor in response to a compressive force on the first part.

Methods of minimally-invasively treating mitral valve regurgitation. The methods include advancing a device in a collapsed configuration into a coronary sinus, causing a distal anchor of the device to expand, exposing a connecting member of the device, pulling proximally on the device, causing a proximal anchor of the device to expand, and releasing the device.

Devices for treating mitral valve regurgitation, including a distal expandable anchor, a proximal expandable anchor, and a fixed length connecting member extending from the proximal expandable anchor to the distal expandable anchor, where at least one of the proximal and distal anchors includes first and second arm segments that extend from one end of the device toward the connecting member and the other anchor when in a collapsed delivery configuration, and where the at least one of the proximal and distal anchors that comprises the first and second arm segments has an expanded configuration in which the first and second arm segments extend radially outwardly such that the first and second arm segments extend away from one another toward the connector, and meet one another at a location axially spaced from the end of the device.
