Embolisation system for promoting clot formation

An embolisation system comprising:

• the apparatus of any preceding claim;
• and
• a delivery element for delivering the embolisation device to a bodily lumen through the delivery catheter;
• wherein the recapture mechanism is actuatable to decrease the radial profile the set of flexible bristles to a radial profile smaller than an inner radius of the distal tip of the delivery catheter.

A method of manufacturing an apparatus comprising an embolisation device for promoting clot formation in a bodily lumen, the embolisation device comprising a core and a plurality of flexible bristles extending outwardly from the core, the bristles having a collapsed delivery configuration and an expanded deployed configuration in which the bristles extend at least radially outwardly from the core to contact the lumen and to anchor the device in the lumen, the method comprising:

• providing a delivery catheter;
• providing a core;
• providing a set of flexible bristles configured to extend radially outwardly from the core and longitudinally in a proximal direction opposite to a direction in which the embolisation device is configured to be delivered from a delivery catheter;
• and
• providing a recapture mechanism, actuatable independently of the movement of the delivery catheter over the bristles, for moving the set of bristles to a lower radial profile than an expanded deployed configuration of the set of bristles before the delivery catheter is moved over the set of flexible bristles.
