Patent number: 7141046Abstract: 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: December 13, 2001Date of Patent: November 28, 2006Assignee: PulmonxInventors: Rodney A. Perkins, Peter P. Soltesz, Robert Kotmel

Publication number: 20060264772Abstract: Minimally invasive methods, systems and devices are provided for qualitatively and quantitatively assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding bronchus of the target compartment. The feeding bronchus is occluded by the catheter and a variety of measurements are taken with the use of the catheter in a manner which is of low risk to the patient. Examples of such measurements include but are not limited to flow rate, volume and pressure. These measurements are used to determine the presence of collateral ventilation and to quantify such collateral ventilation.Type: ApplicationFiled: December 7, 2005Publication date: November 23, 2006Applicant: PULMONXInventors: Nikolai Aljuri, Anthony Wondka, George Surjan, Kirk Davis, Peter Soltesz, Rodney Perkins

Publication number: 20060251278Abstract: The present invention provides hearing systems and methods that provide an improved high frequency response. The high frequency response improves the signal-to-noise ratio of the hearing system and allows for preservation and transmission of high frequency spatial localization cues.Type: ApplicationFiled: May 3, 2005Publication date: November 9, 2006Applicant: Rodney Perkins and AssociatesInventors: Sunil Puria, Rodney Perkins

Publication number: 20060023908Abstract: A hearing system for producing audio signals perceptible to an individual. The hearing system includes a transducer having a surface adapted to attach to a middle-ear acoustic member of the individual, wherein the transducer is responsive to variations in a magnetic field emitted by a transmitter to directly vibrate the acoustic member. The transmitter is supported within an ear canal of the individual. The transmitter has a coil and a core positioned so that the distal end of the core is located at a predetermined distance and orientation relative to the transducer.Type: ApplicationFiled: July 28, 2004Publication date: February 2, 2006Applicant: Rodney C.

Patent number: 6913579Abstract: An electrosurgical working end and method for obtaining a tissue sample for biopsy purposes, for example, from a patient's lung or a liver. The working end provides curved jaw members that are positioned on opposing sides of the targeted anatomic structure. The working end carries a slidable extension member that is laterally flexible with inner surfaced that slide over the jaw members to clamp tissue therebetween. As the extension member advances, the jaws compress the tissue just ahead of the advancing extension member to allow the laterally-outward portion of the extension member to ramp over the tissue while a cutting element contemporaneously cuts the tissue. By this means, the transected tissue margin is captured under high compression. The working end carries a bi-polar electrode arrangement that engages the just-transected medial tissue layers as well as surface layers to provides Rf current flow for tissue welding purposes that is described as a medial-to-surface bi-polar approach.Type: GrantFiled: April 30, 2002Date of Patent: July 5, 2005Assignee: SurgRx, Inc.Inventors: Csaba Truckai, Rodney Perkins, John H.

Publication number: 20030055331Abstract: Devices and methods are provided for acquiring and analyzing an image data file to generate diagnostic information reflecting an individual lung compartment. A lung compartment could be an entire lobe, a segment or a subsegment and beyond, hereinafter subsegments and beyond will be referred to simply as segments. Such analysis is used to assess the level of disease of individual lung compartments, both for quantification of the disease state and for determining the most appropriate treatment plan. This analysis allows the imaging technology to be used as a functional diagnostic tool as well as an anatomical diagnostic tool. To this end, dynamic data or images may also be acquired at specific points throughout the breathing cycle. Since air movement in and out of a lung compartment during the breathing cycle is a direct indicator of lung function in some diseases like emphysema, analysis of images during the breathing cycle will indicate levels of disease.Type: ApplicationFiled: September 11, 2002Publication date: March 20, 2003Applicant: PULMONxInventors: Robert Kotmel, Peter Soltesz, Anthony Wondka, Rodney Perkins

Publication number: 20030051733Abstract: 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 10, 2002Publication date: March 20, 2003Applicant: PulmonxInventors: Robert Kotmel, Peter Soltesz, Anthony Wondka, Rodney Perkins

Publication number: 20020077593Abstract: Apparatus, systems, methods, and kits are provided for isolating a target lung segment and treating that segment, usually by drug delivery or lavage. The systems include at least a lobar or sub-lobar isolation catheter which is introduced beyond a second lung bifurcation (i.e., beyond the first bifurcation in a lobe of the lung) and which can occlude a bronchial passage at that point. An inner catheter is usually introduced through the isolation catheter and used in cooperation with the isolation catheter for delivering and/or removing drugs or washing liquids from the isolated lung region. Optionally, the inner catheter will also have an occluding member near its distal end for further isolation of a target region within the lung.Type: ApplicationFiled: February 11, 2002Publication date: June 20, 2002Applicant: PULMONXInventors: Rodney A.
