Devices, systems, and methods for detecting fluid flow
A medical device may comprise a plurality of prongs, each of the prongs having a sensor configured to detect a flow of fluid; and a sleeve disposed radially outward of the plurality of prongs. The sleeve may be configured to move proximally and distally relative to the plurality of prongs to transition the plurality of prongs from a contracted configuration to an expanded configuration.
1. A medical device, comprising
a plurality of prongs, each of the prongs having a sensor configured to detect a flow of fluid, and wherein each of the prongs includes an indicator that communicates whether the respective sensor detects the flow of fluid; and
a sleeve disposed radially outward of the plurality of prongs;
wherein the sleeve is configured to move proximally and distally relative to the plurality of prongs to transition the plurality of prongs from a contracted configuration to an expanded configuration.
2. The medical device of claim 1 , wherein the sensor is disposed at a distal end of the prong, and wherein the distal ends of the plurality of prongs are closer to one another in the contracted configuration than in the expanded configuration.
3. The medical device of claim 1 , wherein each of the plurality of prongs is attached to a base.
4. The medical device of claim 3 , wherein each of the plurality of prongs is attached to the base via a hinge.
5. The medical device of claim 3 , wherein the base is annular or tubular.
6. The medical device of claim 3 , wherein the base is configured to slidably receive an endoscope in an opening of the base.
7. The medical device of claim 6 , wherein distal ends of the prongs are configured to be visible on a view using an imaging device of the endoscope.
8. The medical device of claim 1 , wherein the sensor includes at least one of an ultrasound sensor or an optical sensor.
9. The medical device of claim 1 , wherein, in the contracted configuration, distal ends of the prongs are closer to a central longitudinal axis of the sleeve than in the expanded configuration.
10. The medical device of claim 1 , wherein moving the sleeve proximally relative to the prongs transitions the plurality of prongs from the contracted configuration to the expanded configuration.
11. The medical device of claim 1 , wherein the indicator includes a light.
12. The medical device of claim 1 , wherein, in at least one of the contracted configuration or the expanded configuration, distal ends of the prongs form a circular shape.
13. The medical device of claim 12 , wherein the sleeve is further configured to transition the plurality of prongs from the expanded configuration to a partially expanded configuration, wherein the distal ends of the plurality of prongs are closer to one another in the partially expanded configuration than in the expanded configuration.
14. The medical device of claim 12 , wherein the distal end of each of the prongs includes a distal tip that is angled radially inward relative to a proximal portion of the prong.
15. A medical device, comprising
a detection device including a plurality of prongs, each of the prongs having a sensor at a distal end of the prong, wherein the sensor is configured to detect a flow of fluid, wherein the distal end of each of the plurality of prongs includes an indicator that communicates whether the respective sensor detects the flow of fluid, wherein the detection device is configured to transition from a first configuration to a second configuration, and wherein the distal ends of the plurality of prongs are radially closer to one another in the first configuration than in the second configuration; and
an endoscope, wherein an outer surface of the endoscope is received within an opening of the detection device.
16. The medical device of claim 15 , wherein the detection device further includes a sleeve disposed radially outward of the plurality of prongs, and wherein the sleeve is configured to move proximally and distally relative to the plurality of prongs to transition the plurality of prongs from the first configuration to the second configuration.
17. The medical device of claim 15 , wherein the sensor includes at least one of an ultrasound sensor or an optical sensor.
18. The medical device of claim 15 , wherein each of the plurality of prongs is attached to a base, and wherein the base has an opening configured to slidably receive the endoscope therein.
19. The medical device of claim 18 , wherein the endoscope includes an imaging device, and wherein distal ends of the prongs of the detection device are configured to be visible on a view using the imaging device.
20. A method of treatment comprising:
positioning an endoscope having a detection device at a treatment site in a body lumen of a patient, wherein the detection device includes a plurality of prongs, wherein a distal end of each of the plurality of prongs includes an ultrasound sensor or an optical sensor;
transitioning the plurality of prongs of the detection device from a collapsed configuration to an expanded configuration, wherein the distal ends of the plurality of prongs are radially closer to one another in the collapsed configuration than in the expanded configuration; and
using the ultrasound sensor or the optical sensor of the detection device to determine whether there is a flow of fluid proximate to one or more of the plurality of prongs, and wherein the distal end of each of the plurality of prongs includes an indicator that communicates whether the respective sensor detects the flow of fluid.
