TISSUE SHAPING DEVICE

摘要

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.

1. A method of orienting an intraluminal cardiac device within the coronary sinus for the treatment of mitral valve regurgitation, the method comprising:
advancing an intraluminal cardiac device in a collapsed configuration into a coronary sinus, the intraluminal cardiac device comprising a distal expandable anchor, a proximal expandable anchor, and a connecting member extending between the distal and proximal expandable anchors, the connecting member predisposed with a curved configuration that generally corresponds to the curved shape of the coronary sinus, expanding the distal expandable anchor within the coronary sinus; anchoring the distal expandable anchor against movement in the coronary sinus; deploying the connecting member such that at least a portion of the curved configuration of the connecting member generally corresponds to the curved shape of the coronary sinus and such that the connecting member is disposed on the inside curve of the coronary sinus; expanding the proximal expandable anchor within the coronary sinus; and anchoring the proximal expandable anchor against movement in the coronary sinus.
