Patent number: 9993362Abstract: An adjustable knee brace for fitting a variety of leg sizes and adjustable to limit flexion or extension motion of a knee. The knee brace includes an adjustable length provided by a strut that telescopes within a receiver. A latch assembly mounted on the receiver selectively applies a frictional force to lock the strut member and the receiver against relative telescoping movement. An adjustable range of motion hinge is operatively associated with the telescoping strut. The hinge includes a hinge plate connected to the strut member and having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys. A range of motion stop is movably positionable relative to the semi-circular peripheral edge and includes a movable latch having teeth.Type: GrantFiled: June 30, 2015Date of Patent: June 12, 2018Assignee: DeRoyal Global Healthcare Solutions LimitedInventors: Mark Costello, Charles J.

Publication number: 20160317774Abstract: Various embodiments of a connector assembly are provided to removably couple a proximal end of a tracheal tube to components associated with a ventilator or an anesthesiology machine. The disclosed embodiments include a compression fitting, which creates an airtight seal between walls of the tracheal tube and components of the compression fitting, thus allowing air to flow to and from a patient.Type: ApplicationFiled: July 7, 2016Publication date: November 3, 2016Inventor: Brian Ledwith

Publication number: 20140290649Abstract: Various embodiments of a tracheal tube having a suction lumen are provided. For example, the suction lumen may be associated with two spaced apart pressure transducers, whereby a pressure drop between the transducers indicates that the suction lumen is free of blockages and a characteristic lack of pressure drop and/or particular pressure curve is indicative of a blockage. In addition, embodiments may include a tracheal tube with sensors configured to sense a buildup of secretions. The sensors may be located proximate to an opening in the suction lumen. In other embodiments, a blockage-clearing system for a suction lumen may be provided that blows air into the suction lumen to clear blockages. In particular, in certain embodiments, the blockage-clearing system may operate to create its own pressurized air source by utilizing the pressure change created in the suction line by a blockage.Type: ApplicationFiled: June 13, 2014Publication date: October 2, 2014Inventors: Seamus Pio Maguire, Lockett E. Wood, Brian Ledwith

Patent number: 8408210Abstract: According to various embodiments, a tracheal tube ventilating device includes a sealing portion near a distal end of the tube. The sealing portion has an electroactive polymer configured to undergo a clinically effective change in volume, thickness, or both upon application of an electrical potential. Such a change in volume, thickness, or both enables sealing of the device against an inner surface of a trachea while permitting the free passage of ventilating gas through the tube. In addition, at least one electrical conductor is coupled to the electroactive polymer and is configured to apply the electrical potential.Type: GrantFiled: December 18, 2009Date of Patent: April 2, 2013Assignee: Covidien LPInventors: James Curley, Brian Ledwith

Publication number: 20110290254Abstract: A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has a tapered upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to prevent rotation of the cannula as well as rotation of the insert in the connector body. Features of the insert and connector body may also interface to mechanically retain the insert in the connector body. Different sizes of cannula may be accommodated by different inserts, while using the same or different connector bodies.Type: ApplicationFiled: May 27, 2010Publication date: December 1, 2011Applicant: Nellcor Puritan Bennett LLCInventors: Paul Waldron, Brian Ledwith, Roger Harrington, Seamus Maguire

Publication number: 20110265798Abstract: Various embodiments of a tracheal tube having spaced lumens and an associated ported adapter are provided. The lumens of the tracheal tube are spaced around the circumference of the tracheal tube to facilitate evacuation (e.g., suctioning and blowing) and other applications at various locations around the circumference of the tracheal tube. The ported adapter includes lumen extensions that may be inserted into the lumens of the tracheal tube, thereby forming a connection between the ported adapter and the tracheal tube. More specifically, hollow ports extending through the lumen extensions and the body of the ported adapter facilitate connection of the lumens of the tracheal tube with external equipment such as, for example, evacuation equipment for suctioning and blowing into and out of the lumens of the tracheal tube.Type: ApplicationFiled: April 30, 2010Publication date: November 3, 2011Applicant: Nellcor Puritan Bennett LLCInventors: Seamus Maguire, Roger Harrington, Brian Ledwith
