  • 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member may be biodegradable to be degraded within a patient or may be detachable from the support member to be withdrawn.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.

  • Patent number: 7951195
    Abstract: A device for repairing a heart valve comprises an implantation instrument. The implantation instrument comprises a first support ring, and a second support ring connected to said first support ring to form a coiled configuration. The first support ring is configured to abut one side of the valve and the second support ring is configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween. The device further comprises an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly. The annuloplasty implant is connected to the implantation instrument for insertion to the annulus.

  • Patent number: 6964684
    Abstract: Devices for repairing and replacing a heart valve in various embodiments, the devices include at least first and second support rings connected together in a coiled configuration to abut opposite sides of a valve annulus. A replacement valve may be secured to the coil-shaped device. Various alternative fastening systems include suture fastening systems, mechanical fastening systems, shape memory alloy fastening systems and other fastening systems relying only on the resilience between adjacent coils. A method generally includes inserting a first end of the coil-shaped member through a valve annulus, rotating a first ring of the coil-shaped member into position on one side of the valve annulus and positioning at least a second ring of the coil-shaped member on an opposite side of the valve annulus.
