Abstract
A method of retrieving a previously implanted device from a native valve of a patient's heart includes attaching the retrieval device to the previously implanted device. An actuation member can engage the previously implanted device to move the previously implanted device from a closed configuration to an open configuration. A clasp capturing member can attach to a clasp of the previously implanted device.
Claims17
A method of retrieving a previously implanted valve repair device from a native valve of a patient with a retrieval device, the previously implanted valve repair device having a pair of paddles that are movable between an open position and a closed position, a pair of gripping clasps that secure the previously implanted valve repair device to the native valve, and a collar, the method comprising:
- securing the retrieval device to the collar of the previously implanted valve repair device;
- engaging the previously implanted valve repair device with an actuation element of the retrieval device to move the pair of paddles of the previously implanted valve repair device from the closed position to the open position;
- and
- removing the retrieval device and the previously implanted valve repair device from the patient.
A method of retrieving a previously implanted valve repair device from a native valve with a retrieval device, the previously implanted valve repair device having a pair of paddles that are movable between an open position and a closed position, a pair of gripping clasps that secure the previously implanted valve repair device to the native valve, and a collar, the method comprising:
- securing the retrieval device to the collar of the previously implanted valve repair device;
- engaging the pair of gripping clasps of the previously implanted valve repair device with at least one capturing member of the retrieval device to remove the pair of gripping clasps from the native valve;
- and
- removing the retrieval device and the previously implanted valve repair device away from the native valve.
A method of retrieving a previously implanted valve repair device from a native valve of a patient with a retrieval device, the previously implanted valve repair device having a pair of paddles that are movable between an open position and a closed position, a pair of gripping clasps that secure the previously implanted valve repair device to the native valve, and a collar, the method comprising:
- securing the retrieval device to the collar of the previously implanted valve repair device;
- engaging the previously implanted valve repair device with an actuation member of the retrieval device to move the pair of paddles of the previously implanted valve repair device from the closed position to the open position;
- rapidly moving the previously implanted valve repair device after the pair of paddles are moved from the closed position to the open position such that the pair of gripping clasps are removed from the native valve;
- and
- removing the retrieval device and the previously implanted valve repair device from the patient.
