Embodiment Construction

[0014] In the following description, certain specific details are set forth to provide a thorough understanding of various embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of these specific details, or with other methods, components, materials, or the like. In other instances, well-known structures associated with systems, bronchoscopic catheter assemblies, markers, anti-migration devices, and / or storage devices have not been shown or described in detail in order to avoid unnecessarily obscuring the description of the embodiments of the invention.

[0015] Various embodiments and features of a bronchoscopic catheter assembly, marker or marker with an anchor according to embodiments of the present invention are illustrated and described in the drawings. In other embodiments of the invention, markers may include additional or different components than those shown in the figures. Furthe...

Abstract

Systems and methods for treating a lung of a patient. One embodiment of a method comprises positioning a leadless marker in the lung of the patient relative to the target, and collecting position data of the marker. This method further comprises determining the location of the marker in an external reference frame outside of the patient based on the collected position data, and providing an objective output in the external reference frame that is responsive to movement of the marker. The objective output is provided at a frequency (i.e., periodicity) that results in a clinically acceptable tracking error. In addition, the objective output can also be provided at least substantially contemporaneously with collecting the position data used to determine the location of the marker.

Description

technical field [0001] The present invention relates to the bronchoscopic implantation of a marker in the lung of a patient, and more particularly to a prefilled delivery catheter with the marker, wherein the marker includes an improved anti-migration device. Background technique [0002] Radiation therapy has become an important and very successful procedure for treating prostate, lung, brain, and many other types of localized cancers. Radiation therapy procedures typically involve (a) a planning process for determining radiation parameters (e.g., dose, shape, etc.), (b) a patient setup process for positioning targets at desired locations relative to the radiation beam, (c) The radiation sessions used to irradiate the cancer, and (d) the validation process used to assess the efficacy of the radiation sessions. Many radiation therapy procedures require several radiation sessions (ie, radiation fractions) over a period of about 5-45 days. [0003] To improve the treatment o...
