  • Patent number: 11160549
    Abstract: A medical securing device for securing an object with a securing member into a tissue comprises an elongated sheath with proximal and distal ends, and a securing member introduction device having proximal and distal ends. The securing member comprises first and second ends. The distal end of the securing member introduction device is configured to extend the second end of the securing member from the sheath and introduce it to or through the tissue via an introduction movement so to secure the portion of the securing member to the object and/or to the tissue. This is advantageously configured to happen without extending the securing member introduction device through the tissue whereupon no extra hole is made to the tissue by the securing member introduction device.

  • Publication number: 20200397580
    Abstract: A device and method for improving the function of a heart valve involves insertion of a device having a first and a second shape into the heart valve. Two contact points of the device in the first shape are separated by a distance essentially corresponding to a distance between two commissures of the heart valve and separated by an increased distance in the second shape. The device is inserted into the heart valve to establish a contact between the contact points and the commissures and transformed from the first shape to said second shape in abutment with valve tissue throughout a cycle of heart action. The device may change the shape of the heart valve by stretching it between the commissures for improving the ability of the heart valve to close.
