Embodiment Construction

[0025] In one example, the present disclosure relates to medical devices and methods that allow for more accurate determination of one or more dimensions (eg, length, height, depth) of a target object captured by imaging techniques. Such target objects may include biological features such as active pathways (eg, blood vessels), items within active pathways (eg, blood clots), and / or any object that may be imaged using one or more imaging techniques. However, other embodiments may capture one or more objects in the target area targeted by the imaging technique. Using a medical example, a user may experience pain throughout or in specific areas of their body. Accordingly, it may be desirable to utilize an imaging device to capture images of the area without specifically targeting particular objects or features. Accordingly, the apparatus may be configured to capture a target area with one or more objects of interest.

[0026] As used herein, the terms "graphical representation"...

Abstract

Medical devices and methods for determining the size of blood vessels are disclosed. In one implementation, a blood vessel sizing device is configured for placement on an area of skin of a patient. The device includes a plurality of radiopaque concentric-circle elements. In one implementation, a blood vessel sizing method includes placing a marker having a plurality of concentric-circle elements on the skin of a patient, imaging a blood vessel of the patient and the device, and comparing the imaged blood vessel to the imaged circles to determine the blood vessel size, the concentric-circle elements allowing a determination of size without errors of parallax.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Application Serial No. 14 / 248,101, filed April 8, 2014, entitled "Blood Vessel Sizing Device," which is U.S. Patent Application Serial No. 13 / 427,084, entitled "Blood Vessel Sizing Device." Continuation-in-Part, filed March 22, 2012, now US Patent 8,971,995, the entire contents of both are hereby incorporated by reference for any and all non-limiting purposes. Background technique [0003] The present disclosure relates generally to medical devices, and more particularly to systems and methods for determining the size of an imaged object on a graphical representation of a medical device, for determining or measuring vessel dimensions during, for example, an angiogram. [0004] Rapid and accurate determination of vessel size is important, for example, when treating narrowed vessels with angioplasty or stenting. If the vessel is not sized correctly, it is possible that a stent that...
