Claims (1)

1. Client Ref.: 23-0223WO01 Attorney Docket No.: 06530-1305-00304 CLAIMS We claim: 1. A medical device comprising: a shaft comprising a working channel; and a distal tip, wherein the distal tip includes an assembly comprising an imaging device and an elevator, and wherein the assembly is movable from a lowered configuration to an angled configuration to move the imaging device and the elevator from the lowered configuration to the angled configuration. 2. The medical device of claim 1, wherein the assembly is movable from the lowered configuration to the angled configuration via a hinge. 3. The medical device of claim 1 or 2, wherein the assembly is housed within a recessed portion of a housing of the distal tip. 4. The medical device of claim 1, wherein the elevator and the imaging device are independently movable from the lowered configuration to the angled configuration. 5. The medical device of claim 1, wherein the imaging device is on a first lateral side of the distal tip, and wherein the elevator is on a second lateral side of the distal tip. 6. The medical device of any one of the preceding claims, wherein a bottom surface of the assembly contacts an inner surface of a housing of the distal tip in the lowered configuration. 7. The medical device of claim 6, wherein the assembly is coupled to a control wire, wherein distal movement of the control wire moves the assembly towards the inner surface of the housing, and wherein proximal movement of the control wire moves the assembly away from the inner surface of the housing. 8. The medical device of claim 7, wherein the elevator is disposed on a first side portion of the assembly, wherein the imaging device is coupled to a second side portion of the assembly, wherein the control wire is coupled to a medial portion of the assembly, and wherein the medial portion is between the first side portion and the second side portion. 9. The medical device of any one of the preceding claims, wherein, in the angled configuration, a longitudinal axis of the assembly forms an angle between 0° to 90° with a longitudinal axis of the shaft. Client Ref.: 23-0223WO01 Attorney Docket No.: 06530-1305-00304 10. The medical device of any one of the preceding claims, wherein the imaging device faces distally in the lowered configuration. 11. The medical device of any one of the preceding claims, wherein the imaging device faces at least partially radially outward in the angled configuration. 12. The medical device of any one of the preceding claims, wherein the elevator is positioned within a groove of the assembly. 13. The medical device of any one of the preceding claims, wherein when the assembly is in the angled configuration, the imaging device and the elevator are angled in approximately a same direction. 14. The medical device of any one of the preceding claims, wherein the assembly further comprises one or more lighting sources and an irrigation opening. 15. The medical device of claim 14, wherein the one or more lighting sources and the irrigation opening are movable from the lowered configuration to the angled configuration.

Description

Client Ref.: 23-0223WO01 Attorney Docket No.: 06530-1305-00304 DISTAL TIPS OF MEDICAL DEVICES AND RELATED METHODS CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of priority of U.S. Provisional Patent Application No.63/515,940, filed on July 27, 2023, the entirety of which is incorporated herein by reference. TECHNICAL FIELD [0002] Various aspects of this disclosure relate generally to distal tips of medical devices and related methods. In particular, aspects of this disclosure relate to rotating distal tips of scope devices, among other aspects. BACKGROUND [0003] A scope device, such as a duodenoscope, an endoscope, or other scope device, may include a handle and a shaft, and the shaft may be insertable into a body lumen of a subject. The shaft may terminate in a distal tip, which may include features such as optical components (e.g., camera, lighting), air/fluid outlets, and working channel openings. An elevator may be disposed at the distal tip and may be actuatable in order to change an orientation of a medical device/tool passed through the working channel. For example, the elevator may be rotatable or otherwise movable, while other components at the distal tip (e.g., the optical components) may be fixed. [0004] During a medical procedure, such as an endoscopic procedure, an operator may need to maneuver the shaft of the scope device through tortuous passages of the body to reach and position the distal tip of the shaft at a target site, e.g., a target site within the gastrointestinal tract (GI). For example, in third space endoscopy, an operator may create a tunnel between the mucosa and muscularis layers of the GI tract and maneuver the shaft through the tunnel to reach the target site. In order to view the target site, the operator may need to retroflex the shaft. A tortuous, retroflexed configuration of the shaft may make it difficult for the operator to use a medical device or tool at the target site. Therefore, a need exists for distal tips of medical devices and related methods. SUMMARY OF THE DISCLOSURE [0005] Each of the aspects disclosed herein may include one or more of the features described in connection with any of the other disclosed aspects, including rotating distal tips of scope devices. [0006] According to some aspects of the present disclosure, a medical device may include a shaft including a working channel and a distal tip. The distal tip may include an assembly including an imaging device and an elevator. The assembly may be movable from a lowered configuration to an angled configuration to move the imaging device and the elevator from the lowered configuration to the angled configuration. [0007] According to some aspects, the assembly may be movable from the lowered configuration to the angled configuration via a hinge. In some examples, the Client Ref.: 23-0223WO01 Attorney Docket No.: 06530-1305-00304 assembly may be housed within a recessed portion of a housing of the distal tip. In some examples, the elevator and the imaging device may be independently movable from the lowered configuration to the angled configuration. In some examples, the imaging device may be on a first lateral side of the distal tip and the elevator may be on a second lateral side of the distal tip. In some examples, a bottom surface of the assembly may contact an inner surface of a housing of the distal tip in the lowered configuration. In some examples, the assembly may be coupled to a control wire. In some examples, distal movement of the control wire may move the assembly towards the inner surface of the housing and proximal movement of the control wire may move the assembly away from the inner surface of the housing. In some examples, the elevator may be disposed on a first side portion of the assembly, the imaging device may be coupled to a second side portion of the assembly, the control wire may be coupled to a medial portion of the assembly, and the medial portion may be between the first side portion and the second side portion. In some examples, in the angled configuration, a longitudinal axis of the assembly may form an angle between 0° to 90° with a longitudinal axis of the shaft. In some examples, the imaging device may face distally in the lowered configuration. In some examples, the imaging device may face at least partially radially outward in the angled configuration. In some examples, the elevator may be positioned within a groove of the assembly. In some examples, when the assembly is in the angled configuration, the imaging device and the elevator may be angled in approximately a same direction. In some examples, the assembly may further include one or more lighting sources and an irrigation opening. In some examples, the one or more lighting sources and the irrigation opening may be movable from the lowered configuration to the angled configuration. [0008] According to some aspects of the present disclosure, a medical device may include a shaft a
