Patent number: 10603209Abstract: Described herein is an apparatus to insert an implantable therapeutic device into a patient. The apparatus includes a proximal handle and a distal placement portion coupled to the proximal handle and configured to hold the implantable therapeutic device. The distal placement portion includes a first side having a first engagement structure at a distal end of the first side, the first engagement structure configured to surround at least a first portion of a proximal end region of the implantable therapeutic device. The distal placement portion includes a second, opposite side having a second engagement structure at a distal end of the second side, the second engagement structure configured to surround at least a second, opposite portion of the proximal end region of the implantable therapeutic device.Type: GrantFiled: June 8, 2018Date of Patent: March 31, 2020Assignee: Forsight Vision4, Inc.Inventors: Eugene de Juan, Jr., Randolph E.

Publication number: 20160258855Abstract: Disclosed herein are improved therapeutic devices and methods and improved porous structures and measurement apparatus for use with therapeutic devices. In many embodiments, a porous structure is measured based on diffusion of the gas through the porous structure. The gas measurement may comprise an amount of gas measured to determine a resistance of the porous structure to diffusion. The diffusion of the gas through the porous structure can be used to determine release of a therapeutic agent through the porous structure, such that targeted amounts of therapeutic agent can be released for extended times and such that therapeutic device reservoir volume and porous frit structure can be tuned to release the therapeutic agent for an extended time above a target amount for the extended time.Type: ApplicationFiled: March 3, 2016Publication date: September 8, 2016Inventors: Kathleen Cogan Farinas, Cary Reich, Randolph E. Campbell, Signe Erickson, Michael S. Barrett

Publication number: 20110130834Abstract: Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway and includes a valve protector that at least partially surrounds a valve member. The valve protector has sufficient rigidity to maintain the shape of the valve member against compression.Type: ApplicationFiled: November 5, 2010Publication date: June 2, 2011Applicant: Pulmonx CorporationInventors: Peter M. Wilson, Antony J. Fields, Hanson S. Gifford, III, John G. McCutcheon, Michael J. Hendricksen, Alan R. Rapacki, David R. Tholfsen, Michael S. Barrett, Ronald Hundertmark, Douglas Sutton

Patent number: 6941950Abstract: Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. An identified region of the lung is targeted for treatment, such as to modify the flow to the targeted lung region or to achieve volume reduction or collapse of the targeted lung region. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. The bronchial isolation of the targeted lung region is accomplished by implanting a flow control device into a bronchial passageway that feeds air to a targeted lung region.Type: GrantFiled: October 10, 2002Date of Patent: September 13, 2005Assignee: Emphasys Medical, Inc.Inventors: Peter M. Wilson, Antony J. Fields, Hanson S. Gifford, III, John G. McCutcheon, Michael J. Hendrickson, Alan R. Rapacki, David R. Tholfsen, Michael S. Barrett, Ronald Hundertmark, Donald Sutton

Patent number: 6510799Abstract: Apparatus, systems and methods for levitating and moving objects are shown and described herein. The embodiments incorporate a track with lower rails having permanent magnets abutted against each other and aligned such that the upper surface of each of the lower rails has a uniform polarity; and the object with upper rails having permanent magnets aligned with the lower rails and oriented to oppose the polarity of the lower permanent magnets. Ferrous backing plates behind the lower rails and/or the upper rails may be incorporated. Embodiments may also incorporate a third rail of an electroconductive material, and a driving disc positioned near the third rail. Permanent magnets in the driving disc may be rotated with the driving disc in the presence of the third rail to accelerate the upper rails with respects to the lower rails.Type: GrantFiled: July 2, 2001Date of Patent: January 28, 2003Assignee: Magna Force, Inc.Inventors: Karl J. Lamb, Toby Merrill, Scott D. Gossage, Michael T. Sparks, Michael S. Barrett
