| 20080312543 | MEASUREMENT OF PULMONARY HYPERTENSION FROM WITHIN THE AIRWAYS - This is directed to methods and devices suited for airway based measurements of pressure in a pulmonary artery. A device is advanced into an airway and in the vicinity of the pulmonary artery. Physical properties of the pulmonary artery are observed through the airway wall using one or more minimally invasive modalities. In a variation, a bronchial balloon catheter measures pressure of the pulmonary artery. | 12-18-2008 |
| 20090076491 | METHODS FOR MAINTAINING THE PATENCY OF COLLATERAL CHANNELS IN THE LUNGS USING CRYO-ENERGY - The 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 methods produce and 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. Devices and methods apply cryo-energy to maintain the patency of the surgically created openings. | 03-19-2009 |
| 20090124883 | AIRWAY BYPASS SITE SELECTION AND TREATMENT PLANNING - This invention relates to systems and methods for site selection and placement of extra-anatomic passages altering gaseous flow in a diseased lung. | 05-14-2009 |
| 20090131765 | METHOD AND SYSTEM FOR MEASURING PULMONARY ARTERY CIRCULATION INFORMATION - Minimally invasive systems and methods are described for measuring pulmonary circulation information from the pulmonary arteries. A transbronchial Doppler ultrasound catheter is advanced through the airways and in the vicinity of the pulmonary artery. Doppler ultrasound energy is sent through the airway wall and across the pulmonary artery to obtain velocity information of blood flowing through the artery. The velocity information is used to compute pulmonary circulation information including but not limited to flowrate. | 05-21-2009 |
| 20090143678 | DEVICES FOR CREATING PASSAGES AND SENSING BLOOD VESSELS - Devices and methods are disclosed for creating passages in tissue and detecting blood vessels in and around the passages. The devices may be used to create channels for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). In addition, the devices may be used to sample tissue during biopsy or other medical procedures where perforating a blood vessel could result in injury to a patient. | 06-04-2009 |
| 20090275840 | BLOOD VESSEL SENSING CATHETER HAVING WORKING LUMEN FOR MEDICAL APPLIANCES - Devices and methods are disclosed for providing a sensing element to scan tissue and detect the presence of structures within the tissue to avoid the structures when performing a procedure on the tissue. A catheter includes a blood vessel sensing assembly and a working lumen adapted to receive a medical appliance or instrument for performing various medical procedures. | 11-05-2009 |
| 20090287087 | DEVICES FOR CREATING PASSAGES AND SENSING FOR BLOOD VESSELS - Devices and methods are disclosed for creating passages in tissue and detecting blood vessels in and around the passages. The devices may be used to create opening in tissue without removing a sensing assembly from the tissue. The devices herein may be used for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). In addition, the devices may be used to sample tissue during biopsy or other medical procedures where perforating a blood vessel could result in injury to a patient. | 11-19-2009 |
| 20100305463 | AIRWAY BYPASS SITE SELECTION AND TREATMENT PLANNING - This invention relates to systems and methods for site selection and placement of extra-anatomic passages altering gaseous flow in a diseased lung. | 12-02-2010 |
| 20100312141 | TISSUE SAMPLING DEVICES, SYSTEMS AND METHODS - Methods, devices, and systems are described herein that allow for improved sampling of tissue from remote sites in the body. A tissue sampling device comprises a handle allowing single hand operation. In one variation the tissue sampling device includes a blood vessel scanning means and tissue coring means to excise a histology sample from a target site free of blood vessels. The sampling device also includes an adjustable stop to control the depth of a needle penetration. The sampling device may be used through a working channel of a bronchoscope. | 12-09-2010 |
| 20110146673 | METHODS FOR TREATING CHRONIC OBSTRUCTIVE PULMONARY DISEASE - The methods and devices disclosed altering gaseous flow within a lung to improve the expiration cycle of individuals having Chronic Obstructive Pulmonary Disease. | 06-23-2011 |
| 20110146674 | DEVICES FOR DELIVERING SUBSTANCES THROUGH AN EXTRA-ANATOMIC OPENING CREATED IN AN AIRWAY - Devices and methods for delivering substances to lung tissue through an extra-anatomic passage created in an airway. | 06-23-2011 |
