Publication number: 20040059263Abstract: The invention provides a device for measuring an inside diameter of a body lumen, such as an air passageway. The device includes a flexible catheter having an inflation lumen, a fluid dispenser in fluid communication with the inflation lumen and operable to communicate a measurable fluid volume change with the inflation lumen, and an expandable member in fluid communication with the inflation lumen and having a known relationship between volume and a changeable transverse dimension, the transverse dimension being changeable in response to fluid volume changes of the fluid dispenser and arranged for placement adjacent to opposing portions of an interior wall of the air passageway. The expandable member may be dimensioned for transoral placement into the air passageway, and may comprise a balloon that includes a complaint material.Type: ApplicationFiled: September 24, 2002Publication date: March 25, 2004Applicant: Spiration, Inc.Inventors: Lauri J.

Publication number: 20030216769Abstract: An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.Type: ApplicationFiled: May 17, 2002Publication date: November 20, 2003Inventors: David H. Dillard, Hugo X. Gonzalez, Seung Yi, Lauri J.

Publication number: 20030216730Abstract: An electrosurgery device according to an embodiment of the invention captures a lymph nodule and resects it. The lymph node is captured with a vacuum and resected it with an electrode, which minimizes bleeding and limits the potentially malignant node from coming into contact with surround tissue as it is resected and removed. This limits the potential for inadvertent cancer spread. An electrosurgery device according to an embodiment of the invention also allows several lymph nodes to be resected in a single procedure, each lymph node being easily indexed according to its nodal station and stored in a manner that limits the potential for cross-contamination. An electrosurgery device according to an embodiment of the invention further provides a collector for individually receiving resected lymph nodes. The collector may be easily detached and sent to pathology without interrupting resection of other lymph nodes.Type: ApplicationFiled: May 14, 2002Publication date: November 20, 2003Applicant: Spiration, Inc.Inventors: Robert Lawrence Barry, Lauri J.

Publication number: 20030212412Abstract: An obstructive device prevents air from being inhaled into a lung portion to collapse the lung portion while providing mucus transport from the lung portion. When placed in an air passageway serving the lung portion, the obstructing member defines a pathway for mucus transport between the obstructing member and the air passageway. The device may include a tubular-shaped anchor to retain the device in the air passageway. A pathway for mucus transport is provided between a portion of the anchor and a portion of the obstructing device.Type: ApplicationFiled: May 9, 2002Publication date: November 13, 2003Applicant: Spiration, Inc.Inventors: David H.

The device includes an obstructing member that prevents air from being inhaled into the lung portion to collapse the lung portion, and an anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the air passageway wall. The anchoring device may frictionally engage the obstructing member and the air passageway, or engage both by piercing. The engagement provided by the anchoring device may be releasable for removal of the obstructing member. The anchoring device may be balloon expandable from a first shape to a second shape that engages the obstructing member and the air passageway. The obstructing member may be a one-way valve.Type: ApplicationFiled: April 16, 2002Publication date: October 16, 2003Applicant: Spiration, Inc.Inventor: Lauri J. DeVore

Publication number: 20030183235Abstract: A system and method deploys a bronchial obstruction device in an air passageway communicating with a lung portion to be at least temporarily collapsed. The system includes a conduit configured to be passed down a trachea, into a bronchus communicating with the trachea and into the air passageway communicating with the lung portion. The system further includes a capsule dimensioned to house the bronchial obstruction device and to be advanced down an internal lumen of the conduit into the air passageway. The capsule has a break-away distal end configured to release the bronchial obstruction device for deployment in the air passageway upon being pushed from the capsule by a pusher member.Type: ApplicationFiled: April 17, 2003Publication date: October 2, 2003Applicant: Spiration, Inc.Inventors: Jenni Rimbaugh, Lauri J.

Publication number: 20030154988Abstract: An intra-bronchial device provides a medicant intra-bronchially. The medicant may be used for controlling biological interaction of an intra-bronchial obstruction device with the patient, to treat a disease or condition of the lungs such as pneumonia or lung cancer, or to treat a systemic disease or condition. The medicant is provided by associating a medicant with the intra-bronchial device, either before, at the time of placement, or after placement. The medicant may overlie at least a portion of the intra-bronchial device, be absorbed into at least a portion of the intra-bronchial device, or be carried in a chamber. The intra-bronchial device may further include an absorptive member, and the medicant is absorbed by the absorptive member.Type: ApplicationFiled: June 21, 2002Publication date: August 21, 2003Applicant: Spiration, Inc.Inventors: Lauri J.

Publication number: 20030158515Abstract: The present invention includes an intra-bronchial device, system, and method for providing a therapeutic agent to a patient. A device includes a flow control member for placement in an air passageway communicating with a lung portion, and when deployed in the air passageway inhibits a therapeutic agent distal of the control member from moving proximal of the control member, and includes the therapeutic agent associated with the flow control member. The control member may inhibit movement of the therapeutic agent by limiting airflow, and may include a one-way valve limiting exhalation of air from the lung portion. The control member may include a flexible membrane impervious to air flow, or a separator arranged to inhibit the movement of the therapeutic agent. The control member may include at least one anchor, and the anchor may be releasable from the air passageway for removal of the intra-bronchial device.Type: ApplicationFiled: December 11, 2002Publication date: August 21, 2003Applicant: Spiration, Inc.Inventors: Hugo X.

Patent number: 5658364Abstract: The invention is a method of making fiber optic-to-metal connection seals. The optical fiber and a preform made of a sealing material are inserted into a metal cup. The metal is then heated to a temperature which melts the sealing material to form a hermetic seal between the cup and the fiber optic. The hermetic sealing material is selected from glass, glass-ceramic or braze and the metal is selected form stainless steel, a metal alloy or a high-strength superalloy. In a preferred method, the optical fiber is coated with a plastic buffer or pliant metal jacket.Type: GrantFiled: September 6, 1994Date of Patent: August 19, 1997Assignee: EG&G Mound Applied TechnologiesInventors: Lauri J.
