Abstract
The invention relates to an annuloplasty device for use on a posterior annulus of a mitral valve, including at least a first and a second anchor unit, preferably a plurality of anchor units, that are deployable to the mitral valve by means of a vascular delivery device, such as a catheter, and positionable in a row along the annulus, including anchor means arranged on each of the first and second anchor units, wherein the first and second anchor units are interconnected by connection means defining a distance between the first and second anchor units, further including pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together, wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row.
Claims16
A delivery device with a first annuloplasty device and a second annuloplasty device, the first and second annuloplasty devices for use on a posterior annulus of a mitral valve, the delivery device for delivering and deploying the first and second annuloplasty devices to the annulus of the mitral valve, the first and second annuloplasty devices each comprising:
- at least a first and a second anchor unit that are deployable to the mitral valve by means of the delivery device and positionable in a row along the annulus, anchor means being arranged on each of the first and second anchor units;
- connection means interconnecting the first and second anchor units and defining a distance between the first and second anchor units;
- and
- pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together;
- wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row;
- and
- wherein the delivery device comprises:
- a first flexible tube and a second flexible tube, the first annuloplasty device being housed in the first flexible tube and the second annuloplasty device being housed in the second flexible tube prior to being delivered, the first and second flexible tubes being for a simultaneous delivery of the first and the second annuloplasty devices;
- a guiding wire for guiding the first and second flexible tubes to the annulus;
- and
- retracting means for retracting the first and second flexible tubes relative to the at least first and second anchor units of the first and second annuloplasty devices, respectively, so as to successively release the anchor units from the respective flexible tube.
An annuloplasty device, for use on a posterior annulus of a mitral valve, comprising:
- at least a first and a second anchor unit that are deployable to the mitral valve by means of a vascular delivery device and positionable in a row along the annulus, anchor means being arranged on each of the first and second anchor units;
- connection means interconnecting the first and second anchor units and defining a distance between the first and second anchor units;
- and
- pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together;
- wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row;
- and
- wherein the anchor means have a trident shape.
An annuloplasty device, for use on a posterior annulus of a mitral valve, comprising:
- at least a first and a second anchor unit that are deployable to the mitral valve by means of a vascular delivery device and positionable in a row along the annulus, anchor means being arranged on each of the first and second anchor units;
- connection means interconnecting the first and second anchor units and defining a distance between the first and second anchor units;
- and
- pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together;
- wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row;
- wherein a distal end of the annuloplasty device carries fixing means for fixing the distal end of the annuloplasty device to the annulus;
- and
- wherein the fixing means are formed by at least one of clamps and pliers.
A delivery device with an annuloplasty device, the annuloplasty device for use on a posterior annulus of a mitral valve, the delivery device for delivering and deploying the annuloplasty device to the annulus of the mitral valve, the annuloplasty device comprising:
- at least a first and a second anchor unit that are deployable to the mitral valve by means of the delivery device and positionable in a row along the annulus, anchor means being arranged on each of the first and second anchor units;
- connection means interconnecting the first and second anchor units and defining a distance between the first and second anchor units;
- and
- pulling means for reducing the distance between the first and second anchor units so as to pull the annulus together;
- wherein the anchor units are arranged to be rotatable to one another around a longitudinal axis extending along the row;
- and
- wherein the delivery device comprises:
- at least one flexible tube, in which the annuloplasty device is housed prior to being delivered;
- a guiding wire for guiding the flexible tube to the annulus;
- and
- retracting means for retracting the flexible tube relative to the at least first and second anchor units of the annuloplasty device so as to successively release the anchor units from the flexible tube;
- wherein a wall of the tube, on its inner side, has a cross-sectional profile that provides a form-fit to a corresponding cross-sectional profile of an outer surface of the anchor units so as to prevent a rotation of the anchor units within the flexible tube.
