Abstract
A medical device for delivering and retrieving a medical implant is disclosed comprising a sheath, a wire having a distal end and being movable in a lumen of the sheath in a longitudinal direction of the sheath. The distal end comprises a locking structure for receiving and interlock with a complementary mating surface of a medical implant, wherein the locking structure comprises a first locking surface aligned in a first radial direction to lock rotational movement of the implant, when received in the locking structure, around the longitudinal direction. The wire comprises a pivotable locking portion having an open and a closed position, the locking portion has a locking structure with a recess locking movement of the implant, when received in the locking structure, in the longitudinal direction, when the locking portion is in the closed position.
