Filed:

Nov 19, 2004

Appl. No.:

10/994169

Inventors:

Mark L. Mathis - Fremont CA, US
Leonard Kowalsky - Bothell WA, US
David G. Reuter - Bothell WA, US
Cruz Beeson - Sacramento CA, US

Assignee:

Cardiac Dimensions, Inc. - Kirkland WA

International Classification:

A61F 2/06

US Classification:

623 236, 623 111

Abstract:

An anchor anchors a therapeutic device having an elongated body within a body lumen. The anchor includes a fixation member carried on the device which is adjustable from a first configuration that permits placement of the device in the body lumen to a second configuration that anchors the device within the body lumen. The anchor further includes a lock that locks the fixation member in the second configuration. The fixation member may be locked in any one of a plurality of intermediate points between the first configuration and a maximum second configuration.

International Classification:

A61F 2/06

US Classification:

623 236

Abstract:

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.

International Classification:

A61F 2/24

US Classification:

623 237, 128898

Abstract:

A tissue shaping device adapted to be deployed in a lumen to modify the shape of target tissue adjacent to the lumen. In one embodiment the device includes first and second anchors; a connector disposed between the first and second anchors; and a focal deflector disposed between the first and second anchors and may be adapted to extend away from the lumen axis and toward the target tissue and/or away from the lumen axis and away from the target tissue when the device is deployed in the lumen. The invention is also a method of modifying target tissue shape. The method includes the steps of providing a tissue shaping device comprising proximal and distal anchors, a connector disposed between the proximal and distal anchors, and a focal deflector; placing the tissue shaping device in a lumen adjacent the target tissue; applying a shaping force from the focal deflector against a lumen wall to modify the shape of the target tissue; and expanding the proximal and distal anchors to anchor the device in the lumen.

International Classification:

A61F 2/24

US Classification:

623 237

Abstract:

A device affects the mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus within the heart and a second anchor configured to be positioned within the coronary sinus of the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart. The second anchor, when deployed, anchors against distal movement and is moveable in a proximal direction. The device further includes a connecting member having a fixed length permanently attached to the first and second anchors. As a result, when the first and second anchors are within the coronary sinus with the first anchor anchored in the coronary sinus, the second anchor may be displaced proximally to affect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry.
