The device (10) has feeler units e.g. ring (30) and loops (31), deployed and arranged to change from a stowed form to a functional deployed form under control of a remote controlling unit so as to detect cavities of a native aorta valve (50) and a coronary valve (52), and to implant the device with reference to a position of the cavities. The feeler units are made from a shape memory material. The remote controlling unit is detachable, and comprises a retaining sleeve (42) to hold the feeler units in the stowed form. An independent claim is also included for a non-surgical and non-therapeutic aiming method for implantation of an implant.
