Remotely activated mitral annuloplasty system and methods
First Claim
Patent Images
1. An implant for applying pressure to the mitral valve annulus of a patient, comprising:
- a body, configured to be positioned within the coronary sinus of the patient by a delivery device, the body being adjustable between a first configuration and a second configuration that applies pressure on the mitral valve annulus when the body is positioned within the coronary sinus;
a tensioning member, extending within the body between a proximal end of the body and a distal end of the body, the tensioning member adjusting the body from the first configuration to the second configuration by drawing the proximal end of the body and the distal end of the body together when a tension of the tensioning member is changed; and
an electronically driven actuator comprising a motor, the actuator being carried by the body and configured to adjust the implant between the first configuration and the second configuration by changing the tension of the tensioning member after positioning the body within the coronary sinus and after the delivery device is removed from the patient.

Abstract
Disclosed are implants and methods for remote remodeling of a mitral valve annulus. The implant comprises a body transformable from a flexible configuration for navigation to a treatment site, to a remodeling configuration for, in one application, applying pressure to the posterior leaflet of the mitral valve. On board electronics allow post deployment adjustment of the implant.

22. A medical apparatus for remodeling a mitral valve annulus adjacent to the coronary sinus of a patient, comprising:
-
an elongate body, having a proximal end and a distal end, the elongate body being movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus; an electronically driven module comprising a motor, carried by the elongate body, and configured to transform the elongate body between the first delivery configuration and the second remodeling configuration; and a forming member positioned within the elongate body, a distal portion of the forming member being coupled to the elongate body distal end and a translatable proximal portion of the forming member being positioned at the elongate body proximal end; wherein the elongate body is configured to be transluminally delivered within the patient by a delivery device, and the electronically driven module is configured to transform, by translation of the forming member proximal portion within the elongate body, the elongate body within the coronary sinus after removal of the delivery device from the patient. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. An implant for positioning within a patient, comprising:
-
an elongate flexible body that is sized and shaped to be positioned within a body lumen of the patient; an electronically actuated forming element extending through a portion of the body and coupling a distal portion of the body to a proximal portion of the body, the forming element being manipulatable within the portion of the body; and a detachable coupling on the body, that removably couples the body to a deployment device; wherein manipulation of the forming element deflects the distal portion of the body with respect to the proximal portion of the body by adjusting a tension of the forming element between the distal portion of the body and the proximal portion of the body; wherein, the forming element is configured to be electronically actuated to deflect the distal portion of the body with respect to the proximal portion of the body after the body is positioned in the body lumen of the patient and after the body is decoupled from the deployment device. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A medical apparatus for remodeling a mitral valve annulus adjacent to the coronary sinus of a patient, comprising:
-
an elongate body, having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the elongate body being movable from a first configuration, for transluminal delivery to at least a portion of the coronary sinus, to a second configuration, for remodeling the mitral valve annulus; an electronically driven module comprising a motor, carried within the elongate body, the module configured to transform the elongate body between the first configuration and the second configuration; and a tension cable extending, within the elongate body lumen, between the proximal end and distal end, a distal portion of the tension cable being coupled to the elongate body distal end and a proximal portion of the tension cable being coupled to the module; wherein the elongate body is configured to move between the first configuration and the second configuration in response to adjustments of tension, by the module, in the tension cable.
