摘要： An occlusion device (30) includes at least one self-expanding frame (42, 44) and graft material (46). Occlusion occurs by constricting the graft material (46) at a substantially central point or at an end of the device. The constriction is sized such that a guide wire (34) is able to pass therethrough. A valve mechanism (50) includes a screen (52) made from a resilient material and which includes a closable opening (54). The valve mechanism (50) allows a guide wire to pass through the occlusion device (30) whilst an effective physical barrier is maintained after removal of the guide wire (34).

摘要： A delivery assembly (10) for an implant (30) includes a release mechanism comprising a locking element (52) and a blocking member (56). The locking element (52) includes a latching pin (14) that engages with an eyelet (54) in the implant (30) to attach the implant (30) to a distal end of an inner catheter (36) of the deployment of the delivery assembly (10). The blocking member (56) prevents premature disengagement of the latching pin (14) from the implant (30). Withdrawal of the blocking member (56) allows disengagement of the latching pin (14) once the implant (30) has been correctly positioned within a patient's vasculature. The locking pin (52) and the blocking member (56) extend along the lumen of the inner catheter (36) from a handle (12) at the proximal end thereof, and are arranged such that a guide wire (34) is also able to extend through the lumen of the inner catheter (36). The locking pin (52) and the blocking member (56) preferably have a crescent-shaped transverse cross section. The release mechanism allows an implant (30) to be retrieved either during deployment of the implant (30) to allow the surgeon to correct any mislocation of the implant (30), or in order to remove a previously deployed temporary implant (30) from a patient.
