  • Patent number: 8470027
    Abstract: A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve, and a second loop-shaped support, which is configured to abut a second side of the heart valve opposite to said first side, whereby a portion of the valve tissue is trapped between the first and second supports. An outer boundary of the second support is greater than an outer boundary of the first support.

  • Patent number: 8128691
    Abstract: A device for improving the function of a heart valve comprises: a support member formed from a shape memory material, and a restraining member providing a restraining action on a course of the support member. The support member may abut one side of the valve conforming to the shape of the valve annulus upon said shape memory material assuming an activated shape while the restraining member restrains the course of the support member. The restraining action is removable for allowing the support member to assume a desired, altered course. The restraining member may be biodegradable to be degraded within a patient or may be detachable from the support member to be withdrawn. The support member according to another embodiment presents a shape change in that an increased cross-section is associated with a shortened length of the support member. The support member according to yet another embodiment has a first and a second activated shape.

  • Publication number: 20100331971
    Abstract: A device for repairing a heart valve comprises a medical device (10). The medical device (10) comprises an element in order to downsize the annulus upon insertion and allow the leaflets to open and close properly. The medical device (10) provides a temporary or permanent downsizing of the heart valve. An annuloplasty implant and/or heart valve prosthesis is in embodiments releasably attached to the medical device for insertion to the annulus and permanent fixation of the latter in a desired shape.
