Medical device for a cardiac valve implant
First Claim
1. A medical implant delivery and retrieval device comprisinga sheath,a wire having a distal end and being movable in a lumen of said sheath in a longitudinal direction of said sheath, said distal end comprising a locking structure for receiving and interlocking with a complementary mating surface of a medical implant,wherein said locking structure comprises a first locking surface aligned in a first radial direction (R) to lock rotational movement of said implant, when received in said locking structure, around said longitudinal direction,wherein said wire comprises a pivotable locking portion having an open and a closed position, and the locking portion has a locking structure with a recess locking movement of said implant, when received in said locking structure, in said longitudinal direction, when said locking portion is in the closed position andwherein said first locking surface is curved in a radial direction.

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.
