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.

11. A device that effects the condition of a mitral valve annulus of a heart comprising:
-
an elongated body dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus;
a fixation member carried by the device, the fixation member being adjustable from a first configuration that permits placement of the device in the coronary sinus to a second configuration that anchors the device within the coronary sinus the fixation member being elongated and having a first end hingedly coupled to the device body, wherein the fixation member extends along the device body closely spaced to the device body when in the first configuration and wherein the fixation member is pivoted from the device body when in the second configuration to engage the coronary sinus and anchor the device in the coronary sinus, and wherein the fixation member includes a second end opposite the first end;
a support that renders the fixation member substantially rigid when in the second configuration, wherein the support comprises a support member having a first end hingedly coupled to the fixation member second end, wherein the support member has a second end opposite the support member first end; and
a lock that locks the fixation member in the second configuration, wherein the lock locks the support member second end on the device body. - View Dependent Claims (12, 13)

25. An assembly that effects the condition of a mitral valve annulus of a heart, the assembly comprising:
-
a mitral valve therapy device dimensioned to be placed in the coronary sinus adjacent the mitral valve annulus, the device including an elongated body, a fixation member carried by the device, the fixation member being adjustable from a first configuration that permits placement of the device in the coronary sinus to a second configuration that anchors the device within the coronary sinus, and a lock that locks the fixation member in the second configuration, the fixation member being elongated and having a first end hingedly coupled to the device body wherein the fixation member extends along the device body when in the first configuration, and wherein the fixation member includes a second end opposite the first end;
a flexible catheter having a lumen that receives the device and being dimensioned to be advanced into the coronary sinus to place the device adjacent the coronary sinus, wherein the catheter transitions the fixation member from the first configuration to the second configuration and wherein the fixation member is pivoted from the device body into the second configuration by distal movement of the catheter with respect to the device to engage the coronary sinus and anchor the device in the coronary sinus;
a support that renders the fixation member substantially rigid when in the second configuration, wherein the support comprises a support member having a first end hingedly coupled to the fixation member second end, wherein the support member has a second end opposite the support member first end, and wherein the lock locks the support member second end on the device body when the support member second end is in a locked position; and
a tether receivable by the catheter lumen and engagable with the device to pull the device distally with respect to the catheter. - View Dependent Claims (17, 26, 27, 28, 29)

40. An anchor that anchors, in a body lumen, a device having an elongated body dimensioned to be placed in the body lumen, the anchor comprising:
-
a fixation member carried on the device, the fixation member being 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, wherein the fixation member is elongated and has a first end hingedly coupled to the device body, wherein the fixation member extends along the device body closely spaced to the device body when in the first configuration and wherein the fixation member is pivoted from the device body when in the second configuration to engage the body lumen and anchor the device in the body lumen wherein the fixation member includes a second end opposite the first end;
a support that renders the fixation member substantially rigid when in the second configuration, wherein the support comprises a support member having a first end hingedly coupled to the fixation member second end, wherein the support member has a second end opposite the support member first end; and
a lock that locks the fixation member in the second configuration, wherein the lock locks the support member second end on the device body. - View Dependent Claims (41, 42)

43. A mitral valve regurgitation treatment device comprising:
-
an elongated body dimensioned to be placed in a coronary sinus of a heart adjacent a mitral valve annulus; and
an anchor adjustable from a first configuration that permits placement of the device in the coronary sinus to a second configuration that anchors the device within the coronary sinus, the anchor comprising;
an elongated fixation member having a first end coupled to the device body and a second end opposite the first end, wherein the fixation member extends along the device body closely spaced to the device body when the anchor is in the first configuration and wherein the fixation member is pivoted from the device body when the anchor is in the second configuration to engage the coronary sinus and anchor the device in the coronary sinus; and
a support member having a first end hingedly coupled to the fixation member second end, the support member rendering the fixation member substantially rigid when the anchor is in the second configuration. - View Dependent Claims (2, 3, 44, 45, 46, 47, 48)
