Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority under 35 U.S.C. § 119 from U.S. Provisional Application No. 63/479,411, filed Jan. 11, 2023, which is incorporated by reference herein in its entirety. TECHNICAL FIELD Various aspects of this disclosure relate generally to medical treatment systems, devices, and related methods thereof. More specifically, embodiments of the disclosure relate to devices for treatment of, for example, blockages within the common bile duct and the pancreatic duct. BACKGROUND During a medical procedure, for example an endoscopic retrograde cholangiopancreatography, or ERCP, procedure, an operator may utilize endoscopic techniques to remove blockages, such as stones, or calculi, from the common bile duct. Occasionally, these blockages may be impacted into the wall of the bile duct, or may have a size which necessitates use of a wire basket to remove the blockages. However, a guidewire used to position a wire basket within the bile duct may not be ideally positioned with respect to the wire basket, making positioning of the basket and blockage retrieval difficult. Alternatively, the wire basket may not be positioned via a guidewire, which may result in accidental placement of the basket within the pancreatic duct. The current disclosure may solve one or more of these issues or other issues in the art. SUMMARY Each of the aspects disclosed herein may include one or more of the features described in connection with any of the other disclosed aspects. Aspects of the disclosure relate to, among other things, systems, devices, and methods for removal of material from a lumen within the body of a patient (for example, within the common bile duct and/or the pancreatic duct) during medical procedures. Aspects of the disclosure also relate to, among other things, a retrieval basket having features, such as loops, for accommodating a guide wire and positioning the basket relative to the guide wire. According to an example, a medical device may include an actuator and a basket at a distal end of the actuator. The basket may include a plurality of wires, and a plurality of eyelets extending from at least one wire of the plurality of wires, where the basket is configured to be transitioned from a collapsed configuration to an expanded configuration. Any of the medical devices described herein may include any of the following features. The plurality of eyelets is formed integrally with the at least one wire of the plurality of wires. The plurality of eyelets includes at least 4 eyelets. In the expanded configuration, each of the wires of the plurality of wires is configured to be moved outwardly with respect to a central axis of the medical device. The plurality of eyelets extends from only one wire of the plurality of wires. A guide wire extending through each of the eyelets of the plurality of eyelets. In the expanded configuration, the guide wire is configured to be arranged at approximately a periphery of the basket. In the expanded configuration, the guide wire is configured to follow a shape of the at least one wire to which the plurality of eyelets is coupled. The guide wire is configured to extend through each of the eyelets of the plurality of eyelets from a proximal end of the basket to a distal end of the basket. Each of the eyelets includes a shape memory material. An aperture defined by each of the eyelets lies in a plane perpendicular to a central longitudinal axis of the basket. A diameter of each of the eyelets is in a range of 1 mm to 1.5 mm. In the collapsed configuration, the plurality of eyelets is configured to receive a shipping mandrel. One of the eyelets includes an atraumatic end cap disposed on a distalmost end of the basket. A sheath surrounding the actuator. According to another example, a medical device may include an actuator, a basket at a distal end of the actuator, where the basket includes a plurality of wires, and a plurality of eyelets extending from at least one wire of the plurality of wires, where each of the plurality of eyelets is formed integrally with the at least one wire of the plurality of wires, and a guide wire extending through each of the eyelets of the plurality of eyelets, where the basket is configured to be transitioned from a collapsed configuration to an expanded configuration, and where in the expanded configuration, the guide wire is configured to follow a shape of the at least one wire having the plurality of eyelets. Any of the medical devices disclosed herein may include any of the following features. The guide wire is configured to be arranged at approximately a periphery of the basket. Each of the eyelets includes a shape memory material. According to another example, a method for manufacturing a medical device may include forming a plurality of loops in a first wire, where the first wire is in a first configuration, heating the first wire to a first temperature while the first wire is in the fi
