The invention relates in general to the field of heart surgery. In the surgical field, instruments are used in order to examine the interior of living organisms and/or to use for operative interventions. These also include implants for the production of the functionality of a heart. The invention relates to such an implantable device and a method for eliminating regurgitation in the area of the heart. The implantable device is an annuloplasty ring with a large number of tissue anchors. An unfolded annuloplasty ring is positioned in the cavity of a body element in order to constrict a bodily opening. Using the minimally-invasive technique, each tissue anchor of the annuloplasty ring is intravascularly inserted in advance into a precise position on the edge of the mitral valve annulus. The annuloplasty ring that is configured in the shape of an arc or circle is mounted and fastened to the thus anchored fastening means in order to influence in size and shape the septal and lateral annulus of the mitral valve and to close the gap between the anterior and posterior cusps in the valve.

Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the risk of injury to the patient.

Various embodiments of an implant delivery systems including at least one removable actuator to reshape a valve annulus are described. The systems may use the removable actuator to customize annular reshaping at a treatment site and withdraw the actuator from the treatment site following custom reshaping to provide a low profile annuloplasty implant.

A prosthetic cardiac valve assembly and method of implanting the same is disclosed. In certain disclosed embodiments, the prosthetic valve assembly is an annuloplasty ring with an attached artificial valve. The prosthetic valve assembly can be secured to native heart tissue by suturing or other suitable method of the annuloplasty ring to the native heart tissue. The prosthetic valve leaflets of the prosthetic valve can also be anchored to the native heart tissue to prevent prolapse. In certain embodiments, the prosthetic valve leaflets are anchored to the native papillary muscles. In still other embodiments, the prosthetic valve assembly contains exactly the number of prosthetic valve leaflets as are in the native valve that the prosthetic valve assembly is configured to replace. With the prosthetic valve assembly properly positioned, it will replace the function of the native valve.

In some examples, the disclosure describes an annuloplasty device that comprises a tube-like structure configured to extend around at least part of a circumference of an annulus of a cardiac or vascular valve of a patient, and at least one anchor configured to anchor the tube-like structure to the annulus. The tube-like structure is configured to decrease a distance between valve leaflets that extend from the annulus.

Heart tissue electrical activity mapping used to guide the placement of devices to intervene in (treat) structural heart disease. In some embodiments, the intervention comprises placement of an implantable device, and/or positioning of a therapeutic device used to remove and/or remodel tissue. In some embodiments, electrical activity mapping is performed along with spatial mapping of a body cavity. In some embodiments, the intervention device position is compared to the measured positions of anatomical structures critical to heart electrical function to assess and/or prevent complications due to the device damaging heart electrical function.

An implantable device delivered and deployed with a visualization and/or imaging system. An imaging element is positioned on a distal end of a flexible elongate member of the visualization/imaging system. The distal end with the imaging element is positioned adjacent the implant and/or the implant site, and moved relative to the longitudinal axis of the flexible elongate member to adjust the viewing field of the imaging device.

Devices, systems, and methods for delivering various implantable devices, such as heart valve implants, with the use of a steerable imaging element are described. An imaging element is positioned adjacent the implantable device and implant site, a relationship between the implantable device and the implant site is visualized and/or imaged, and the implantable device is anchored and/or adjusted with reference to the visualization and/or imaging thereof.

An annuloplasty implant is disclosed comprising first and second support rings arranged in a coiled configuration around an axial direction, and being adapted to be arranged on opposite sides of native heart valve leaflets to pinch said leaflets. At least part of said first and second support ring is formed from a carbon fiber material. The first and second support rings are resiliently movable with respect to each other in opposite directions along said axial direction. A method of manufacturing an annuloplasty implant is also disclosed.

The present disclosure relates to an arrangement, a loop-shaped support, a prosthetic heart valve and a method of repairing or replacing a native heart valve. With the method or the arrangement, leakage or regurgitation between a prosthetic heart valve and the surrounding valve tissue is prevented. In one embodiment, an arrangement for replacement or repair of a native heart valve is provided, which comprises a loop-shaped support 41 and a prosthetic heart valve 70 and wherein an outer segment 32 of the loop-shaped support 41 is positionable towards surrounding valve tissue of a native heart valve and wherein an outer surface 74 of the prosthetic heart valve 70 is positionable towards an inner segment 34 of the loop-shaped support 41 so as to prevent paravalvular leakage or regurgitation between the prosthetic heart valve 70 and the surrounding valve tissue of the native heart valve.
