Abstract
Methods and devices for blocking orifices and occluding cavities within a patient are provided. The device in one variation comprises first and second tubular members attached to a collapsible sealing element. The device can be placed through an orifice and the collapsible sealing element can be collapsed to seal the orifice. An embolic may be introduced distal to the sealing element to occlude a cavity. The device may incorporate a locking mechanism which can be engaged to lock the sealing element into the collapsed position. The device may incorporate a valve to prevent flow through the tubular members, for example to prevent egress of the embolic from a cavity. The device can be detached to provide a permanent seal of the orifice, and can retain the embolic within the cavity. The device may be used in conjunction with a stent or other retention device to assist the sealing element in maintaining the seal.
