Description

PRIORITY This application claims the benefit of priority under 35 USC § 119 to United States Provisional Patent Application Serial No. 62/954,875, filed December 30, 2019, which is incorporated by reference herein in its entirety and for all purposes. FIELD This disclosure relates generally to medical devices, systems, and methods for locating devices and/or anatomy during medical procedures. More particularly, in some embodiments, the disclosure relates to medical device and/or anatomy locating devices, access devices, and systems and methods thereof, for use during gastrojejunostomy procedures. BACKGROUND Various health issues, e.g., obesity and diabetes, affect a growing population and may cause additional diseases, increasing risk of a patient's health. Surgical procedures such as bariatric surgery, e.g., to restrict a portion of a stomach and/or bypass portions of the intestine and/or other portions of the gastrointestinal (GI) tract, may be an option for certain patients with these and/or other health issues. These types of procedures may have significant side effects, e.g., such as enteric hormonal changes, and may be invasive surgical procedures with associated complications, tissue trauma, anastomotic leaks, infections, and/or additional surgeries to modify the initial surgery, e.g., to reorient the placement of a bypass device, which in some instances may put patients at increased risk. Accordingly, it may be desirable for less invasive medical devices, systems, and related methods for treating the GI tract and/or bypassing portions of the intestine, to reduce complications associated with treating some of these and other health issues. This disclosure may solve one or more of these problems or other problems in the art.
