Abstract
The present invention refers to a sealable device for temporary or permanent surgical placement through a bone to provide a passage into a cavity or internal anatomic site in a mammal. The sealable device comprises two preferred embodiments: in the first one the device comprises two members, the first one provides a passage through the bone, and the second one, which is movable, is used as a stopper means for the first member, and in the second embodiment, a third removable member is added, which may be connected with said second end of said first member so that the device is affixed to the bone it runs through. The device can be used, for example, for diagnostic purposes, for topical in situ therapy, of medical treatment or for viewing into the cavity. The cavity may be, for instance, the sinus maxillaris. If so, the temporary or permanent placement of the device is carried out via the canine fossa or the lower meatus.
