Title: Method and apparatus for completing a wellbore
Inventor: MACKENZIE ALAN
IPC: E21B43/08
Filed: 2000-12-07
Granted: 2005-02-15
Abstract: A method and apparatus to provide a large bore hook hanger system incorporating sand exclusion at a junction in a multilateral wellbore includes the running of a lateral liner having an expandable sleeve positioned thereon to bridge a milled window from the lateral borehole to the primary borehole, expandable sleeve including a pre-machined window and a hook to hang the liner from the primary borehole. The hook further acts to center the pre-machined window in the expandable sleeve to provide access to the primary wellbore. The expandable sleeve is preferably covered on its outer surface with an elastomeric material and is outwardly concentric to an expandable packer for run-in. Once the expandable sleeve is positioned at the appropriate location in the junction, the expandable packer is inflated thus permanently deforming the expandable sleeve into contact with the open hole of the lateral borehole thereby preventing sand or gravel ingress to the primary borehole.

Inventor: BRAIN ARCHIBALD IAN JEREMY
IPC: A61M25/00
Filed: 2000-10-09
Granted: 2009-06-16
Abstract: An artificial airway device (20) for use in unconscious patients comprises a laryngo-pharyngeal mask (52) including a roughly elliptical expandable masking ring (55). The expandable mask sealingly surrounding the laryngeal inlet (50) when expanded to obstruct communication between the laryngeal inlet and oesophagus (37). One or more airway tubes (125, 127) connected to the mask provide for fluid flow to a portion of the mask facing the laryngeal inlet when the mask sealingly surrounds the laryngeal inlet. A gastro-tube (75) connected to the mask is bonded along most of its length to the airway tube(s) and provides a fluid flow-path to the surface of the mask facing the oesophagus when the mask sealingly surrounds the laryngeal inlet. The cross-section area of the gastro-tube is at least as great as that of the airway tube(s). The distal end of the gastro tube passes through the masking ring at its narrower distal region (62) where, when installed in a patient, it abuts the oesophagus; and the distal portion (80) of the gastro-tube (75) flattens when the mask is deflated to facilitate smooth passage behind the larynx during insertion through the patient's airway (22).
