A medical arrangement for introducing an object into an anatomical target position

A medical arrangement configured to introduce an object from a distal end of the arrangement into an anatomical target position, the medical arrangement comprising a first introducer and a guide wire, wherein:

• said guide wire has at least a first curved shape;
• said at least first curved shape has a preformed shape capable of being delivered in a straightened configuration through said first introducer and is configured to be activated to said at least first curved shape within or near the anatomical target position;
• said guide wire is configured to be introduced before the object into or towards said anatomical target position;
• said object is configured to be delivered along the guide wire into said anatomical target position after the guide wire is at least partially introduced from the distal end portion of the first introducer, whereupon said object is configured to follow said guide wire and said first curved shape of the guide wire into said anatomical target position;
• and
• said guide wire is configured to be retracted after said object has been introduced into said anatomical target position so that said object maintains the shape taken when introduced into said anatomical target position.
