Abstract:
Embodiments of a sizing device that can be used to measure the size of airways lumens, such as those connected to lungs. The sizing device can have different expandable elements in order to accurately and consistently measure the particular dimensions of a lumen. In some embodiments, markings vie wable by a user can be used to determine the particular size.
Abstract:
Embodiments of the present invention include devices, systems, and methods for implanting and locating traceable markers in a region of a patient's body such as a lung, and in particular lung nodules which may be difficult to locate using traditional means. Further embodiments describe devices, systems, and methods that may be used to treat regions in the lung such as lung nodules with various treatment modalities including heating, microwave irradiation, chemical treatment, and which may be used in conjunction with embodiments of the traceable markers described herein.
Abstract:
Devices, systems, and methods for diagnosing physiological parameters of the lungs and treating associated medical conditions are disclosed herein. In particular, certain embodiments permit detection of air flow in lung passageways, air leaks, gas concentration (in particular oxygen), and temperature measurements. Measurements obtained using the devices, systems, and methods disclosed herein may also be used to determine optimal treatment sites for medical conditions such as emphysema, COPD, or lung volume reduction.
Abstract:
In certain embodiments, a device is configured to be compressed and inserted into the distal end of an endoscope. The delivery device can be configured to deliver the delivery catheter to the site of one or more fistulas in the wall of a body cavity or lumen within a patient. The delivery catheter is configured to deliver the device to the site of the one or more fistulas. The device is configured to expand at the site of the one or more fistulas and substantially seal the fistula in one or more directions. In some embodiments, at least a portion of the device is coated with and/or constructed of biocompatible material. In some configurations, the device is configured to be implanted for an extended period of time or even permanently. In some embodiments, at least a portion of the device is constructed of biodegradable, dissolvable and/or bioabsorbable material.
Abstract:
Devices and methods for occluding airways in at least one direction are disclosed, in some cases, the devices include anchoring mechanisms configured to keep an operative portion of the device (e.g., a valve) in position along a length of a lumen in which the device is deployed. The anchoring mechanisms can include anchors configured to settle into the lumen walls with little or no axial movement of the operative portion of the device. In some embodiments, the anchoring mechanisms include a secondary set of anchors configured to engage with the lumen wall to reduce, inhibit, or prevent axial movement of the operative portion of the device when the primary anchors settle into the walls of the lumen.
Abstract:
Embodiments of a simulated valve device can be used to determine whether a valve device would fit within a particular airway. The simulated valve device can include a shaft having at least one strut extending radially therefrom. The strut and at least part of the shaft can be surrounded by a membrane for viewing through a bronchoscope. In some embodiments, the membrane can include markings for viewing by a user.
Abstract:
The invention provides for treating deleterious body tissue located within healthy body tissue by isolating the deleterious tissue (70) from blood, air, and fluid communication. The device includes two structures (82, 86), each having a corresponding circumferential surface (83, 87) arranged to circumscribe the deleterious body tissue. When the first and second circumferential surfaces (83, 87) are brought together in an aligned relationship with the deleterious body tissue between the structures (82, 86), the two circumferential surfaces (83, 87) co-act to isolate the deleterious body tissue (70) from communication with the healthy body tissue. The deleterious tissue is resected according to the invention by allowing it to become ischemic and necrotic, or by excision.
