Publication number: 20190388034Abstract: The present invention provides systems, methods, devices and kits for assessing the level of pulmonary disease in individual lung compartments. A lung compartment comprises a subportion of a lung, such as a lobe, a segment or a subsegment, for example. By measuring individual lung compartments, the level of disease of the pulmonary system may be more precisely defined by determining values of disease parameters reflective of individual subportions or compartments of a lung. Likewise, compartments may be separately imaged to provide further measurement information. Once individual compartments are characterized, they may be compared and ranked based on a number of variables reflecting, for example, level of disease or need for treatment. Such comparison may be aided by simultaneous display of such variables or images on a visual display. Further, the same tests may be performed on the lung as a whole or on both lungs and to determine the affect of the diseased lung compartments on the overall lung performance.Type: ApplicationFiled: September 5, 2019Publication date: December 26, 2019Applicant: Pulmonx CorporationInventors: Robert Kotmel, Peter Soltesz, Anthony Wondka, Rodney Perkins

Patent number: 9131942Abstract: Methods, systems and devices are provided for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung and occluding various lung passageways with the use of occlusal stents. The occlusal stents are delivered with the use of an occlusal stent delivery system which is loaded with the occlusal stent with the use of an occlusal stent loading system.Type: GrantFiled: March 6, 2013Date of Patent: September 15, 2015Assignee: PULMONX CORPORATIONInventors: Anthony Wondka, Peter P.

Patent number: 8486060Abstract: A method for tissue ablation is described. An RF applicator including an electrode carrier with one or more bipolar electrodes thereon is positioned at a target tissue site for tissue ablation. A current at an initial current level is passed through the one or more bipolar electrodes to the target tissue site to apply an initial power density to destroy tissue for an initial time period. A vacuum source in fluid communication with the RF applicator is employed to remove moisture generated during ablation away from the target tissue site. After the initial time period, the power density is ramped up by increasing the current passed through the one or more bipolar electrodes to the target tissue site for a second time period.Type: GrantFiled: September 18, 2006Date of Patent: July 16, 2013Assignee: Cytyc CorporationInventors: Robert Kotmel, Russel M.

Patent number: 8177769Abstract: Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation/access catheter.Type: GrantFiled: June 22, 2010Date of Patent: May 15, 2012Assignee: Pulmonx CorporationInventors: Rodney C.
