Patent number: 6692494Abstract: The devices and methods disclosed herein are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, these devices and methods produce and to maintain collateral openings or channels through the airway wall so that expired air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. The devices and methods also disclose locating and selecting a site for creation of a collateral opening.Type: GrantFiled: August 7, 2000Date of Patent: February 17, 2004Assignee: Broncus Technologies, Inc.Inventors: Joel D.

Publication number: 20030233099Abstract: This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airway of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the air ways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airway to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter.Type: ApplicationFiled: April 14, 2003Publication date: December 18, 2003Applicant: Broncus Technologies, Inc.Inventors: Christopher James Danaek, Michael Biggs, Keith M. Burger, Bryan Loomas, Thomas Keast, Dave Haugaard

Patent number: 6634363Abstract: This relates to treating a lung having at least one symptom of reversible obstructive pulmonary disease, and more particularly, relates to advancing a treatment device into the lung and treating the lung with the device to at least reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease. This also includes additional steps that reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease and to reduce the resistance to the flow of air through a lung.Type: GrantFiled: March 27, 2000Date of Patent: October 21, 2003Assignee: Broncus Technologies, Inc.Inventors: Christopher James Danek, Michael Biggs, Bryan Loomas, Michael D.

Patent number: 6632232Abstract: This invention is a surgical device for producing a generally circular, interlamellar pathway within the corneal stroma of the eye. The device is made up of three major components: a vacuum centering guide having an inner bore which fits at one end against the front of the eye, a barrel which fits within the inner bore of the centering guide and to which is attached the third major component, a generally circular dissecting ring. The dissecting ring is shaped in such way that when an eye surgeon twists the barrel to which the ring is attached, the ring moves through the interlamellar space in the stroma producing the desired channel or pathway. The centering guide may optionally include a ring having one or more pins which firmly engage the cornea's epiphilium. The constituent parts of the surgical device, particularly the dissecting ring, also form a part of this invention.Type: GrantFiled: September 19, 1997Date of Patent: October 14, 2003Assignee: Addition Technology, Inc.Inventors: Bryan Loomas, James Davenport, Mark Mathis

Publication number: 20030070676Abstract: Devices and related methods are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, conduits maintain collateral openings or channels through the airway wall so that air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. The conduits include a center section with a passageway extending through the center section. The conduits further include a distal cage structure which has a passageway and at least one opening in fluid communication with the center section passageway. The medical kits disclosed herein are also directed to maintain collateral openings through airway walls.Type: ApplicationFiled: September 4, 2002Publication date: April 17, 2003Inventors: Joel D.

Publication number: 20020091379Abstract: A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.Type: ApplicationFiled: October 25, 2001Publication date: July 11, 2002Inventors: Christopher J.

Patent number: RE35974Abstract: A method for refractive correction of the eye in order to improve the vision of the eye while not adversely affecting its natural asphericity is described. The method involves determining the amount of correction necessary, selecting an intrastromal corneal ring (ICR) of appropriate thickness to obtain the necessary correction from a selection of ICRs of varying thickness, and inserting the ICR into the corneal stroma. The method may be useful for the correction of mypoia and excessive astigmatism.Type: GrantFiled: April 10, 1996Date of Patent: December 1, 1998Inventors: James Davenport, Bryan Loomas, Mark Mathis, Thomas Silvestrini
