1. Apparatus for occluding a cardiovascular defect or a gap between a medical device and adjacent body tissue, the apparatus for use with a guidewire and a delivery system, the apparatus comprising:
an occlusion device, which has a longitudinally extended form from which the occlusion device is shortenable, the occlusion device comprising:
a compliant balloon (a) defining a fluid-tight balloon chamber, and (b) comprising an inflation port for filling and unfilling a fluid into and from the balloon chamber;
a tube, which (a) is disposed within the fluid-tight balloon chamber, and (b) when the occlusion device is in the longitudinally extended form, forms a longitudinal passage from a proximal side to a distal side of the balloon such that the fluid-tight balloon chamber radially surrounds the tube;
a distal tip element disposed at the distal side of the balloon, and a proximal base element disposed at the proximal side of the balloon;
a locking mechanism; and
a proximal connection element that is disposed at the proximal side of the balloon and is configured to releasably connect the occlusion device to a correspondingly configured distal connection element of the delivery system; and
an elongate actuating element disposed longitudinally slidable in the tube, connected to the distal tip element, and longitudinally moveable with respect to the proximal base element so as to set a distance between the distal tip element and the proximal base element,
wherein the locking mechanism is configured to maintain, between the distal tip element and the proximal base element, the distance set using the elongate actuating element.
