Abstract
An embolisation device (10) for promoting clot formation in a bodily lumen (L) and having a collapsed delivery configuration for delivery of the embolisation device (10) into, and retrieval of the embolisation device (10) from, the bodily lumen (L) and an expanded deployed configuration for anchoring the embolisation device (10) in the bodily lumen (L). The embolisation device (10) comprises a tubular cage (20) having a collapsed delivery configuration and an expanded deployed configuration. The embolisation device further comprises an embolisation member (30) disposed in the tubular cage (20), the embolisation member (30) comprising a stem (31) and a plurality of flexible bristles (32) extending outwardly from the stem, the plurality of flexible bristles having a collapsed delivery configuration and an expanded deployed configuration. The embolisation device (10) is configured such that as the tubular cage (20) is transitioned from its expanded deployed configuration to its collapsed delivery configuration the plurality of flexible bristles (32) is urged by the tubular cage (20) from the expanded deployed configuration of the flexible bristles (32) to the collapsed delivery config…
