Description

Technical Field

[0001] The present disclosure generally relates to medical devices, systems, and related methods for wetting medical instruments. More specifically, at least some embodiments of the present disclosure relate to devices, systems, and related methods for lubricating a medical instrument prior to insertion into a body lumen of a subject.

Background Art

[0002] Medical instruments / devices are often inserted into a subject's body to perform treatment and / or diagnostic procedures within the subject's body. Examples of such devices are catheters that are introduced into the body to access various parts of the subject's living structure and / or deliver treatment to a target tissue. A catheter is inserted into the subject's body through an opening (e.g., a natural opening or an incision) and is delivered to a target tissue site inside the body, for example, through a body lumen. In one embodiment, the catheter can be inserted directly into the subject's mouth and advanced to the target site through the subject's esophagus. In another embodiment, the catheter can be inserted into the subject via a secondary medical device such as a device having a working channel (e.g., a scope such as an endoscope).

[0003] Prior to inserting a catheter into a subject, one or more portions of the catheter or other medical instrument / device can be wetted or lubricated. Wetting one or more portions of a catheter or other medical device / instrument prior to inserting the catheter into a subject can help enhance the comfort of the subject during the procedure. For example, lubricating the catheter can help reduce friction between the catheter or other medical device / instrument and the subject and / or between the catheter and the secondary medical device. Therefore, there is a need for medical systems, devices, and related methods for wetting or lubricating medical instruments during a medical procedure.

Each example disclosed herein may include one or more features described in relation to any of the other disclosed examples.

[0005] According to one embodiment, the medical system may include a fluid source, a fluid reservoir, and a valve. The valve may be coupled to the fluid source and the fluid reservoir to allow fluid flow between the fluid source and the fluid reservoir. The valve may include a first opening configured to receive a medical device. When the medical device is inserted into the first opening of the valve, the medical device may be lubricated by fluid from the fluid source.

[0006] In some embodiments, the medical system may further include an adapter. The first end of the adapter may be coupled to the first opening of the valve. The second end of the adapter may include an opening configured to receive the medical device. The adapter may include a gate configured to prevent fluid flow from the first end of the adapter to the second end of the adapter. The gate may include a first end and a second end. The first end may be fixed to the wall of the adapter. The second end of the gate may be a free end.

[0007] In some embodiments, in the first configuration, the second end of the gate may abut against the lumen wall of the adapter. When the medical device is inserted into the adapter and passes through the gate, the gate may transition to a second configuration. In the second configuration, the second end of the gate may abut against the surface of the medical device. In the second configuration, the gate may be configured to prevent fluid flow from the first end of the adapter to the second end of the adapter. In some embodiments, the second end of the gate may be located between the first end of the adapter and the first end of the gate.

[0008] In some embodiments, the adapter may include a channel extending through the wall of the adapter. The channel may extend along at least a portion of the length of the adapter. In some embodiments, the adapter may be formed integrally with the valve.

[0009] In some embodiments, the valve may further include a first arm, a second arm, a third arm, and a fourth arm. The first arm may be coupled to the fluid source. The second arm may be coupled to the fluid reservoir. The third arm may include the first opening configured to receive the medical device. The fourth arm may include the second opening.

[0010] In some embodiments, the longitudinal axis of the third arm may be angled in a first direction with respect to the longitudinal axis of the first arm. The longitudinal axis of the fourth arm may be angled in a second direction with respect to the longitudinal axis of the first arm. The longitudinal axis of the first arm and the longitudinal axis of the fourth arm may be parallel or coaxial. The longitudinal axis of the second arm and the longitudinal axis of the third arm may be parallel or coaxial.

[0011] In some embodiments, the first direction of the third arm may be opposite to the second direction of the fourth arm. In some embodiments, the fluid reservoir can be fluidly coupled to a medical device.

[0014] In some embodiments, the medical system may further include a stopper. The stopper may be configured in a first configuration to prevent the flow of fluid into the immersion container. The stopper may be configured in a second configuration to allow the flow of fluid into the immersion container.

[0015] In some embodiments, the medical system may further include a coupling fixed to the immersion vessel. The coupling may be configured to removably connect the immersion vessel to the fluid vessel.

[0016] In some embodiments, the walls of the fluid container may define the walls of the immersion container. In another embodiment, the medical device may include a bridge, a base, an arm, and a gap between the base and the arm. The base may extend laterally from the bridge in a first direction. The arm may extend laterally from the bridge in a first direction. The arm may include a nozzle configured to deliver fluid into the gap. When a medical instrument is inserted through the gap, the fluid may be applied to the surface of the medical instrument.

[0017] In some embodiments, the medical device includes a controller, which is configured to control the delivery of the fluid. Any of the examples described herein may have any combination of these features. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0019] Next, aspects of the present disclosure will be referred to in detail, and examples thereof are shown in the accompanying drawings. As far as possible, the same or similar reference numerals are used to refer to the same or similar parts throughout the drawings. The term "distal" refers to the part that is farthest from the user when the device is introduced into a subject (e.g., a patient). In contrast, the term "proximal" refers to the part that is closest to the user when the device is placed within the subject. The proximal direction and the distal direction are labeled with arrows marked "P" and "D", respectively, throughout the various figures.

[0020] Both the general description above and the detailed description below are illustrative and descriptive only and do not limit the claimed features. Where used herein, the terms “comprises,” “comprising,” “has,” “having,” “includes,” “including,” or other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements may include other elements not expressly enumerated or specific to such process, method, article, or apparatus, rather than only those elements. In this disclosure, relative terms such as, for example, “about,” “substantially,” “generally,” and “approximately” are used to indicate a possible variation of ±10% in the described value or characteristic. In addition, terms describing the geometric shape of a component / surface encompass both exact and approximate shapes.

[0021] Medical devices / instruments (e.g., scopes, catheters, guidewires, baskets, forceps, or any other medical devices) are often inserted into the body of a subject to perform therapeutic and / or diagnostic procedures within the subject's body. The terms “medical device” and “medical instrument” are used interchangeably herein. A medical device may be inserted directly into the body of a subject (e.g., through an opening in the subject) or through another medical device, such as an endoscope or other type of scope with a working channel. Insertion of a medical device into a subject and / or into another medical device may be difficult due to friction between the medical devices and / or between the medical device and the tissue of the subject. These frictional forces may result in discomfort, injury to the subject, prolonged procedure time, or other undesirable consequences. To overcome these frictional forces between medical devices and / or between the medical device and the subject, the surface of the medical device is often lubricated.

[0022] Currently, to wet or lubricate medical devices, a portion of the device (e.g., the distal part) is immersed in an open container filled with water, saline solution, or other lubricant. The container may be placed, for example, in a treatment room on a tower or a flat surface (e.g., a counter, table, etc.). The container may occupy valuable space in the treatment room, and the presence of an open container in the treatment room increases the likelihood of water or lubricant spilling onto the floor or other surfaces. Spills can be dangerous to the electrical equipment and / or users of the treatment room.

[0023] This disclosure relates to medical systems, apparatus, and related methods for wetting or lubricating the surfaces of medical devices / instruments. Wetting one or more parts of a medical device before inserting it into a subject or into a working channel of another medical device can provide benefits such as, among other things, improving the comfort of the subject during the procedure. For example, lubricating the device can help reduce friction between the device and the subject and / or between the device and secondary medical devices. Some embodiments described herein utilize a fluid source used in other aspects of medical procedures (e.g., a fluid source for perfusion / lens cleaning) as a fluid source for lubricating the medical device. Aspects of this disclosure may provide a source of lubricating fluid without requiring an open container.

[0024] This disclosure is described with reference to exemplary medical systems for lubricating or wetting medical devices. This may improve the functionality of medical devices / instruments and / or assist medical professionals in performing medical procedures. However, it should be noted that references to specific devices and / or specific procedures are provided for convenience and are not intended to limit this disclosure. Those skilled in the art will recognize that the underlying concepts of the disclosed systems, devices and methods of application may be used in any suitable procedure, medical treatment, or otherwise. The devices, assemblies and systems described herein may be used in combination with other types of medical devices. This disclosure may be understood with reference to the following description and accompanying drawings, where identical elements are indicated by the same reference numerals.

[0025] Referring to Figure 1, an exemplary embodiment of the medical system 10 is shown. The medical system 10 may include a medical device 20, a wetting system 40, and a processing unit 5. The medical device 20 may include a handle 22 and an insertion section 24 (e.g., a shaft or catheter). The insertion section 24 may be connected to the distal end of the handle 22. The insertion section 24 may terminate distally at the distal tip 26. The umbilical 7 may extend from the proximal end of the handle 22 (or another part of the handle 22).

[0026] The umbilical 7 may be detachably coupled to the processing unit 5 (e.g., directly or indirectly). The processing unit 5 may be configured to process information received from the medical device 20 (e.g., sensor data, imaging data, optical data, etc.). In some embodiments, the processing unit 5 may be a controller associated with the medical device 20. The umbilical 7 may include one or more electrical cables and / or optical cables for coupling to the processing unit 5, for example, via a detachable connector. Although not shown, the processing unit 5 may include a visual output (e.g., an internal monitor or screen), or the processing unit 5 may be coupled to a visual output (e.g., an external or separate monitor or screen). Although not shown, the umbilical 7 may additionally or alternatively include one or more lumens for supplying gas or liquid to the handle 22 and / or insertion section 24.

[0027] The handle 22 may include a first actuator 28A and / or a second actuator 28B. The first actuator 28A and / or the second actuator 28B may include a rotatable knob that rotates to push / pull one or more elements extending through the insertion portion 24 and connected to the distal end 30 of the insertion portion 24. For example, the first actuator 28A and / or the second actuator 28B may be configured to rotate about their axes to push / pull actuating elements (e.g., wires, not shown) extending within one or more lumens of the insertion portion 24. The rotation of the first actuator 28A and / or the second actuator 28B may bend the insertion portion 24 and / or the distal end 30, for example, via an articulated joint (not shown). In addition, or alternatively, the handle 22 may include additional actuators (e.g., buttons, knobs, levers, locks, etc.) that can, for example, restrict the movement of the first actuator 28A and / or the second actuator 28B, close or open the forceps, rotate the end effector about its longitudinal axis, raise or lower the elevator, capture an image, and / or provide other functionality to the end effector and / or distal end 30.

[0028] The handle 22 may also include a first valve 32A and a second valve 32B. Although two valves (i.e., the first valve 32A and the second valve 32B) are shown, the handle 22 may include additional valves (e.g., a third valve, a fourth valve, etc.) or fewer valves (e.g., no valves, or only the first valve 32A). In some embodiments, the first valve 32A may be configured to control the supply of air and / or water to the distal end 30. The second valve 32B may be configured to control the application of suction to the distal end 30. Further valves may be used, for example, to control the application of one or more medicines, drugs, materials, etc. to the distal end 30.

[0029] The handle 22 may also include a proximal port / opening 34 which can be fluidically connected to one or more lumens (e.g., working channels) of the insertion section 24. For example, a medical device (not shown in Figure 1) may be inserted into the proximal opening 34 and extend through one or more lumens to the distal end 30. The lumens may have one or more distal openings 36 at the distal tip 26, which may be the most distal end of the distal end 30. The distal openings 36 may be fluidically coupled to the proximal opening 34. In this way, a medical device inserted into the proximal opening 34 may extend distally through the distal openings 36 and may extend distally from the distal openings 36. Additionally or alternatively, one or more materials (e.g., liquids, gels, gases, patches, powders, etc.) may be supplied to the target site through the distal openings 36. Additionally or alternatively, suction may be supplied through the proximal opening 34, for example, to remove debris from the target site through the distal openings 36.

[0030] Although not shown, the distal end 30 may include one or more articular joints. The distal tip 26 may include one or more end effectors and / or openings for suction, irrigation, blowing, and other devices. The distal end 30 may further include one or more devices 38. The devices 38 may include one or more visualization devices (e.g., cameras, image sensors, lenses, etc.), one or more illumination devices (e.g., LEDs, optical fibers, etc.), one or more treatment devices (e.g., laser fibers, elevators, etc.), and / or one or more other devices for otherwise imaging, visualizing, or otherwise treating the treatment site.

[0031] The wetting system 40 may be configured to wet or lubricate a medical instrument (not shown in Figure 1) before it is inserted into the medical device 20, for example, into the proximal opening 34 of the handle 22 of the medical device 20. For example, the medical instrument may be inserted into and / or through the wetting system 40 and lubricated by the wetting system 40. Once lubricated by the wetting system 40, the medical instrument may be inserted into the proximal opening 34 and may extend through one or more lumens to the distal end 30 of the medical device 20.

[0032] In some configurations, the wetting system 40 can be fluidically coupled to one or more aspects of the medical device 20. For example, the wetting system 40 can be fluidly coupled to the proximal opening 34 via an arbitrary conduit 42 extending between the wetting system 40 and the medical device 20. For example, the first end of the conduit 42 can be fixedly or detachably coupled to the wetting system 40. The second end of the conduit 42 can be fixedly or detachably coupled to the proximal opening 34 and / or one or more lumens of the medical device 20. In this way, the medical device can be inserted into the proximal opening 34 of the handle 22 of the medical device 20 via the wetting system 40 and the conduit 42. For example, the medical device may first be inserted into the wetting system 40, where it is lubricated. The lubricated medical device may then extend through the conduit 42 and then into the proximal opening 34 of the medical device 20.

[0033] In addition or alternatively, in some configurations, the wetting system 40 may be fluidically coupled to the umbilical 7 and / or treatment unit 5 of the medical device 20. For example, conduits 42 and / or another conduit 44 (shown by dashed lines) may fluidly couple the wetting system 40 to one or more parts of the umbilical 7 and / or treatment unit 5. The wetting system 40 may be used in conjunction with the medical device 20 or as a standalone system. For example, the wetting system 40 and embodiments discussed herein may be used in conjunction with any medical system or device to which the medical device is wetting or lubricated. In some configurations, the wetting system 40 may be used with an external fluid source. For example, the external fluid source may be a fluid source for irrigation / lens cleaning, used for or in conjunction with the medical device 20.

[0034] Figure 2 shows a front view of an exemplary configuration of the wetting system 140 in use. The wetting system 140 includes a fluid container 144, a reservoir 146, and a valve 148. The valve 148 may be configured to allow fluid communication between the fluid container 144 and the reservoir 146. For example, fluid from the fluid container 144 may flow into the reservoir 146 through the valve 148. Figures 3A to 3C show further details of the valve 148.

[0035] The fluid container 144 may be any flexible or rigid container configured to contain a fluid. For example, the fluid container 144 may be water, saline solution, or an intravenous (IV) bag or bottle. The fluid container 144 may contain a fluid (e.g., water, saline solution, or another fluid). The fluid container 144 may include one or more ports. For example, the fluid container 144 may include a first port 144A and / or a second port 144B. One or both of the first port 144A and the second port 144B may be made of a self-sealing rubber or silicone material. For example, the first port 144A and / or the second port 144B may be punctured once or more times to allow fluid flow in or out of the fluid container 144.

[0036] In some embodiments, the first port 144A may be configured to allow a user to inject additional fluid into the fluid container 144 and / or withdraw fluid from the fluid container 144. The user may, for example, use a needle or an alternative injector to inject fluid into or withdraw fluid from the fluid container 144. In some embodiments, the user may inject a drug, such as a pharmaceutical or another fluid, into the fluid container 144. The drug may be any drug in liquid form, such as an analgesic, coagulant, anticoagulant, or any other drug commonly used in endoscopic procedures. The drug may be combined with another fluid already in the fluid container 144, or it may be the only fluid in the fluid container 144.

[0037] A second port 144B may be configured to allow fluid to flow out of the fluid container 144. For example, the second port 144B may be configured for puncture of the valve 148 by a spike 150. The spike 150 may be configured to facilitate fluid connection between the fluid container 144 and the valve 148. The spike 150 may be conical with a sharp tip for puncturing the second port 144B of the fluid container 144. In some embodiments, the spike 150 may be shaped like a needle. The spike 150 may have an opening 150A at its tip that can provide access to one or more lumens of the valve 148.

[0038] The valve 148 includes a first arm 148A, a second arm 148B, a third arm 148C, and a fourth arm 148D. The first arm 148A, the second arm 148B, the third arm 148C, and the fourth arm 148D may be configured to be oriented in a manner similar to an "X" or cross. In some embodiments, one of the arms (e.g., the second arm 148B) may be omitted so that the valve 148 has a "Y" shape. As shown in Figures 3B and 3C, each of the first arm 148A, the second arm 148B, the third arm 148C, and the fourth arm 148D may have a separate lumen extending longitudinally through it. For example, the first arm 148A has a first lumen 152A, the second arm 148B has a second lumen 152B, the third arm 148C has a third lumen 152C, and the fourth arm 148D has a fourth lumen 152D. The lumens 152A, 152B, 152C, and 152D of each arm 148A, 148B, 148C, and 148D can be in fluid communication with each other. For example, the lumens 152A, 152B, 152C, and 152D can intersect at the joint 154 of the valve 148. For example, the central longitudinal axis of the first arm 148A may be substantially parallel or coaxial with the central longitudinal axis of the fourth arm 148D. The central longitudinal axis of the second arm 148B may be substantially parallel or coaxial with the third arm 148C.

[0039] The central longitudinal axis of the first arm 148A may generally extend upward. The proximal end of the first arm 148A may include a spike 150. The first arm 148A may further include a flange 156. The flange 156 may extend radially outward distal to the spike 150. The flange 156 may be configured, for example, to prevent excessive insertion of the spike 150 into the fluid container 144.

[0040] The fourth arm 148D may generally extend downward. In one example, the fourth arm 148D may be fluidically coupled to the reservoir 146 via a first connector 158. The first connector 158 may be any connector commonly used in the art for fluidly connecting two components. In one example, the first connector 158 may contact the surface of the fourth arm 148D to couple the fourth arm 148D to the reservoir 146. The first connector may be coupled to a first port 146A of the reservoir 146.

[0041] The reservoir 146 can be any flexible or rigid container configured to contain a fluid. For example, the reservoir 146 can be a bag or a bottle. The fluid can flow from the fluid container 144 into the reservoir 146 through the lumens 152A and 152D of the respective arms 148A and 148D.

[0042] The second arm 148B may extend in a first lateral direction away from the first arm 148A. The third arm 148C may extend in a second lateral direction away from the first arm 148A. The second lateral direction may be opposite to the first lateral direction. In this way, the second arm 148B and the third arm 148C may form an angle with respect to the first arm 148A. As shown in Figure 2, the angle between the second arm 148B and the third arm 148C is lateral with respect to the first arm 148A but not perpendicular to it. Alternatively, the second arm 148B and the third arm 148C may each be perpendicular to the first arm 148A. The second arm 148B and the third arm 148C may have the same or different angles with respect to the first arm 148A. In some embodiments, the opening 160 of the second arm 148B may be oriented so that the opening 160 of the second arm 148B faces distally. The opening 162 of the third arm 148C (shown in Figures 3B-3C) may be oriented so that the opening 162 of the third arm 148C faces proximal. In some embodiments, the opening 160 of the second arm 148B may face in the opposite direction to the opening 162 of the third arm 148C.

[0043] As shown in Figures 3A to 3C148, the valve adapter 164 may be coupled to the third arm 148C of the valve 148. Although the valve adapter 164 is not shown in Figure 2, it will be understood that the system 140 in Figure 2 may also include the valve adapter 164. Figure 3A is a front view of the valve 148 and valve adapter 164. Figures 3B and 3C are cross-sectional views of the valve 148 and valve adapter 164 in a first configuration (Figure 3B) and a second configuration (Figure 3C). The valve adapter 164 may be fixedly or detachably coupled to the third arm 148C of the valve 148. In some examples, the valve adapter 164 may be made of one or more flexible, expandable, and / or semi-rigid materials to enable attachment to the valve 148. For example, the valve adapter 164 may be coupled to the valve 148 via friction fit, snap fit, press fit, etc. Additionally or alternatively, the valve adapter 164 may be coupled to the valve 148 via one or more adhesives and / or mechanical fasteners (e.g., screws, rivets, set screws, etc.). The valve adapter 164 may include a combination of materials (e.g., some being rigid and others flexible), or in some embodiments, may be made entirely of rigid material. In other examples, the valve adapter 164 may be formed integrally with the valve 148.

[0044] As shown in Figures 3B and 3C, the valve adapter 164 may be coupled to the third arm 148C such that the lumen 166 of the valve adapter 164 is in fluid communication with the lumen 152C extending through the third arm 148C of the valve 148. For example, the third arm 148C may be inserted into the lumen 166 of the valve adapter 164, and the lumen 166 of the valve adapter 164 may have a wall that is formed to receive and mesh with the third arm 148C. The lumen 166 may open at its longitudinal end. The third arm 148C may be inserted into the first opening 168 of the first end 164A of the valve adapter 164. The second opening 170 may be at the second end 164B of the valve adapter 164 (opposite the first end 164A).

[0045] The channel 172 may extend through the wall 174 of the valve adapter 164 to the lumen 166, thereby opening the side of the lumen 166. Thus, the channel 172 may provide a side opening of the valve adapter 164 to the lumen 166. The channel 172 may extend longitudinally along the valve adapter 164 along a portion of its length. For example, the channel 172 may extend from the second opening 170 of the second end 164B, but not to the first opening 168 of the first end 164A. The channel 172 may facilitate the insertion of an instrument 120 (discussed in further detail below) into the lumen 166, and therefore into the lumen 152C of the third arm 148C. For example, the medical instrument 120 may be inserted into the lumen 166 of the valve adapter 164 via the channel 172 and / or via the second opening 170.

[0046] Referring to Figures 3B and 3C, the valve adapter 164 may include a gate 176. When the third arm 148C is inserted into the lumen 166, the gate 176 may be located between the opening 162 of the third arm 148C and the second opening 170 of the valve adapter 164. In a first configuration, such as shown in Figure 3B (where the medical device 120 is not inserted beyond the gate 176), the gate 176 may be configured to prevent fluid flow from the first opening 162 of the third arm 148C to the second opening 170 of the adapter 164. For example, as indicated by the curved arrow in the lumen 152C of the third arm 148C in Figure 3B, the fluid flow may be stopped and / or reversed by the gate 176.

[0047] The gate 176 may be made of a flexible material. For example, the gate 176 may be rubber, silicone, and / or flexible plastic configured to seal or prevent the flow of fluid within the valve adapter 164. In some embodiments, the gate 176 may extend across the entire width of the lumen 166 of the valve adapter 164 in the first configuration. As shown in Figures 3B and 3C, the gate 176 may have a first end 176A coupled to the wall of the valve adapter 164. The gate 176 may have a second free end 176B (not coupled to, for example, the wall of the adapter 164 or another element). In the first configuration, the free end 176B may be in contact with or abut against the wall of the adapter 164. The wall to which the free end 176B is in contact with or abut against may be, for example, the opposite wall from the wall to which the first end 176A is fixed. The first end 176A may be closer to the second opening 170 than the second end 176B. The second end 176B may extend across the diameter / width of the lumen 166, away from the second opening 170 and toward the first opening 162 of the lumen 166. In an alternative embodiment, the gate 176 may be a partition, a one-way fluid valve, a membrane, or another type of structure. The gate 176 may be, for example, an automatic sealing valve.

[0048] In the second configuration shown in Figure 3C, the medical device 120 can be inserted into the lumen 166 of the valve adapter 164 through the second opening 170 and / or channel 172. When the medical device 120 is inserted into the lumen 166 of the valve adapter 164, the gate 176 can be bent or deformed to accommodate the passage of the medical device 120. The gate 176 can be opened only to the extent that it allows the passage of the medical device 120 and can fit the medical device 120. The second end 176B can be spaced slightly away from the inner surface of the lumen 166 to accommodate the medical device 120. In this way, the gate 176 can be configured to allow the medical device 120 to be inserted through the valve adapter 164 into the opening 162 of the third arm 148C, while preventing fluid from flowing into the lumen 166 through the opening 160. In this way, the gate 176 can form a seal with respect to the medical device 120 in the second configuration. For example, the second end 176B may be configured to contact or abut the surface of the medical instrument 120. The curved arrow in Figure 3C indicates, for example, the fluid flow during or after the medical instrument 120 is inserted beyond the gate 176. As indicated by the arrow, the fluid flow may be stopped and / or reversed by the gate 176.

[0049] Referring again to Figure 2, the first end of the first conduit 178 may be connected to the reservoir 146, for example, via the second port 146B. Tube 180 may extend from the first conduit 178 into the reservoir 146. For example, tube 180 may be inserted into the reservoir 146 to facilitate the flow of fluid from the reservoir 146 to the first conduit 178. The second end of the first conduit 178 may include an adapter 182. The adapter 182 may be configured to connect to a pressure source (not shown) and / or an umbilical 7 (shown in Figure 1). Thus, the adapter 182 may be configured to allow the flow of fluid from the reservoir 146 through tube 180 and the first conduit 178 to the medical device 20. In this way, the fluid from the reservoir 146 may be used with the medical device 20, for example, to provide irrigation and / or lens cleaning.

[0050] In some examples, the second conduit 142 may be fluidly coupled to the second arm 148B via an opening 160. For example, the second conduit 142 may be inserted into the opening 160. Alternatively, the arm 148B may be inserted into the second conduit 142. The second conduit 142 may include a first branch 142A, a second branch 142B, and a third branch 142C. For example, the first branch 142A of the second conduit 142 may be fluidly coupled to the second arm 148B as described above. The first branch 142A may be divided into a second branch 142B and a third branch 142C, each of which may extend from the first branch 142A. The second branch 142B of the second conduit 142 may include an opening / port 143. The functions of the second branch 142B and port 143 will be discussed in more detail below. The end of the third branch 142C may be fluidly coupled to the medical device 20 in Figure 1. For example, the third branch 142C of the second conduit 142 may be inserted into or otherwise coupled to the opening 34 of the medical device 20. For example, a port defining the opening 34 may be inserted into the third branch 142C.

[0051] The first branch 142A, the second branch 142B, and the third branch 142C may be arranged so that the medical instrument 120 can proceed from the first branch 142A into the second branch 142C without being redirected to the third branch 142B. Similarly, the branches 142A, 142B, and 142C may be arranged so that the medical instrument 120 can proceed from the second branch 142C into the third branch 142C without being redirected to the first branch 142A. For example, the angle between the first branch 142A and the third branch 142C may be relatively open / straight. The angle between the second branch 142B and the third branch 142C may similarly be relatively open / straight. On the other hand, the angle between the second branch 142B and the first branch 142A may be relatively sharper (e.g., acute).

[0052] During use, the medical device 120 can be inserted into the valve 148 through the opening 162 of the third arm 148C. In some examples, a valve adapter 164 can be coupled to the third arm 148C of the valve 148. In such embodiments, the medical device 120 can first be inserted into the opening 170 and / or channel 172 of the valve adapter 164 and then into the valve 148 through the opening 162 of the third arm 148C. The medical device 120 could be, for example, a guidewire, a catheter, or any other medical device commonly used in the art and configured for insertion into a patient.

[0053] The medical device 120 may pass through the lumen 152C of the third arm 148C, through the joint 154 between arms 148A, 148B, 148C, and 148D, and enter the lumen 152B of the second arm 148B of the valve 148. In some examples, the medical device 120 may extend through the opening 160 of the second arm 148B and be inserted into the second conduit 142. In some embodiments, the medical device 120 may be inserted into the medical device 20 through an opening 34 (shown in Figure 1) connected to the conduit 142.

[0054] As the medical device 120 passes through the valve 148, fluid from the fluid container 144 may flow into the opening 150A of the spike 150 and through the lumen 152A of the first arm 148A. The fluid may flow through the joint 154 and into the lumen 152D of the fourth arm 148D on its way to the reservoir 146. As the fluid flows through the valve 148 and, in particular, through the joint 154, the fluid may flow over the medical device 120. In this way, the medical device 120 is wet or lubricated.

[0055] In a second configuration of the valve adapter 164 (Figure 3C), the gate 176 may be configured to remove excess fluid from the surface of the medical device 120 as, for example, the medical device 120 is pulled proximally and / or removed from the valve adapter 164. In this way, the gate 176 may have a squeegee effect on the surface of the medical device 120. For example, the free end 176B of the gate 176 may come into contact with the medical device 120 so that when the medical device 120 is pulled proximally and / or removed from the valve adapter 164, fluid from the surface of the medical device 120 is removed or pulled away by the gate 176. The fluid removed from the surface of the medical device 120 may then flow through the lumen 152C of the third arm 148C into the lumen 152D of the fourth arm 148D and into the reservoir 146.

[0056] When the medical device 120 is pulled proximally so that it is near the gate 176, the gate 176 may transition to the first configuration shown in Figure 3B. In this way, the gate 176 may be configured to transition between the first and second configurations one or more times throughout the procedure. For example, when the medical device 120 (or multiple medical devices 120) is inserted and / or removed multiple times throughout the course of the procedure, the gate 176 may be configured to transition between the first and second configurations shown in Figures 3B and 3C, respectively. Thus, the adapter 164 may be configured to prevent or limit the leakage of fluid to the outside of the valve 148 and the valve adapter 164.

[0057] After (and while) wetting the medical device 120 with fluid from the fluid container 144, any excess fluid may flow from the valve 148 into the reservoir 146. The excess fluid may fill the reservoir 146. The fluid from the reservoir 146 is used with the medical device 20. For example, the excess fluid may flow into the umbilical 7 of the medical device 20 via the tube 180. In this way, the excess fluid may be used, for example, to deliver fluid to target tissue via the medical device 20, or to clean the lens of the imaging device of the medical device 20.

[0058] Although not shown, in some embodiments the second arm 148B may include a second gate. The second gate may be configured similarly to the first gate 176. The second gate may be made of a flexible material and may extend throughout the second lumen 152B of the second arm 148B. The second gate may be configured to prevent or restrict the flow of fluid into and out of the second arm 148B and to allow a lubricated medical device 120 to enter the second arm 148B through or over the second gate. For example, the second gate may be configured to prevent or restrict the backflow of fluid from a medical device (e.g., medical device 20) fluidically coupled to the second arm 148B. Additionally or alternatively, the second gate may be configured to prevent or restrict the amount of fluid flowing from a fluid container 144 into the second arm 148B. Therefore, the second gate may be configured to allow the lubricated medical instrument 120 to pass through the second arm 148B, while preventing or limiting additional or excessive fluid flow into the second arm 148B.

[0059] In some examples, port 143 (Figure 2) may be configured to receive a medical device (e.g., medical device 120) so that the medical device 120 inserted into port 143 is not moistened by the moistening system 140. The medical device 120 may be inserted into port 143 and then into a third branch 142C of conduit 142 via a second branch 142B of conduit 142. The medical device 120 may then be inserted into opening 34 (Figure 1) via the third branch 142C.

[0060] One or more parts of the wetting system 140 may be reusable and / or disposable. For example, the fluid container 144 may be configured so that a user can fill or refill the fluid container 144 one or more times. In some embodiments, the valve 148 may be disposable or reusable. Additionally or alternatively, the reservoir 146 may be disposable or multi-purpose. For example, the reservoir 146 may be configured so that a user can remove the liquid captured by the reservoir 146 and reuse the reservoir 146. In this way, the components of the wetting system 140 may consist of one or more materials that can be sterilized.

[0061] Figure 4 illustrates a front view of an alternative wetting system 240. The wetting system 240 includes a fluid vessel 244, a reservoir 246, and an immersion vessel 284. The fluid vessel 244 may be in fluid communication with the reservoir 246 via the lumen of a first conduit 286. The first conduit 286 may extend between the fluid vessel 244 and the reservoir 246. The first conduit 286 may allow fluid flow from the fluid vessel 244 to the reservoir 246.

[0062] The fluid container 244 may have any or all of the features of the fluid container 144 shown in Figure 2. For example, the fluid container 244 may include a first port 244A and a second port 244B. The first port 244A may be configured to allow a user to pour fluid into or withdraw fluid from the fluid container 244. The second port 244B may be configured to allow fluid flow to the reservoir 246 when the second port 244B is punctured by a spike 250. The spike 250 may have any of the features of the spike 150 and may be configured to facilitate fluid connection between the fluid container 244 and the first conduit 286. The spike 250 may be connected to the proximal end of the first conduit 286 or may be formed integrally with the first fluid conduit 286. The flange 256 may have any of the characteristics of the flange 156, and may be configured, for example, to prevent excessive insertion of the spike 250 into the fluid container 244.

[0063] Reservoir 246 can be fluidically coupled to the first conduit 286, for example, by port 246A of reservoir 246. In this way, fluid from fluid container 244 can flow into reservoir 246 through the first conduit 286. Reservoir 246 may have any or all of the features of reservoir 146 described above with respect to Figure 2. For example, reservoir 246 may be any flexible or rigid container configured to contain fluid.

[0064] In some examples, the first end of the second conduit 278 may be connected to the reservoir 246. The tube 280 may extend from the second conduit 278 into the reservoir 246. The second end of the second conduit 278 may include an adapter 282 configured to connect to a pressure source (not shown) and / or the umbilical 7 of the medical device 20 (shown in Figure 1). The second conduit 278, tube 280, and / or adapter 282 may have any or all of the features of conduit 178, tube 180, and / or adapter 182, respectively, as described above with respect to Figure 2. During a procedure, the second conduit 278 may supply fluid from the reservoir 246 to the medical device 20, for example, for irrigation or lens cleaning.

[0065] The third conduit 288 may extend radially outward from a portion of the first conduit 286. The lumen of the third conduit 288 may be in fluid communication with the lumen of the first conduit 286. The third conduit 288 may be configured to allow fluid flow between the fluid container 244 and the immersion container 284, for example, via the first conduit 286 and the third conduit 288. The third conduit 288 may be fixedly or detachably coupled to the immersion container 284.

[0066] The third conduit 288 may include a stopper 290 positioned around the third conduit 288. The stopper 290 may be a clamp (e.g., a roller tube clamp), a valve, a clip, or any other mechanism used to control the flow of fluid through the third conduit 288. For example, in a first closed configuration, the stopper 290 may be configured to prevent the flow of fluid into the immersion vessel 284. In a closed configuration, the stopper 290 may exert an inward force on one or more sides of the third conduit 288. The stopper 290 may compress / compress the third conduit 288 so that multiple walls of the third conduit 288 come into contact with each other, thereby closing the lumen extending through the third conduit 288. In other words, the stopper 290 may clamp and close the third conduit 288. In a second open configuration, the stopper 290 may be configured to allow fluid to flow through the third conduit 288 into the immersion vessel 284. In the open configuration, the stopper 290 does not have to exert an inward force on the wall of the third conduit 288, or it may exert a force on the third conduit 288 that is too small to close the lumen of the third conduit 288. In some examples, the stopper 290 may be configured for manual operation by the user. In other examples, the stopper 290 may be electrically operated or operated via a control module (not shown). In such examples, the stopper 290 may be configured to open and / or close using an electrical input.

[0067] The immersion container 284 may be configured to hold or contain fluid from the fluid container 244. In some embodiments, the immersion container 284 may be permanently or detachably coupled to the reservoir 246 via a coupling 292. For example, the coupling 292 may be a clip or clamp configured to permanently or temporarily couple the immersion container 284 to the reservoir 246. The coupling 292 may hold the immersion container 284 in a desired configuration (e.g., upright). In some embodiments, the coupling 292 may include an adhesive or tacky material so that the coupling 292 can adhere to the reservoir 246 temporarily or permanently.

[0068] The immersion container 284 may have a shape similar to that of a test tube. For example, the immersion container 284 may have a first open end 284A and a second closed end 284B. Part (or all) of the immersion container 284 may have a substantially cylindrical shape.

[0069] The medical device 120 can be inserted into the immersion container 284 through the first open end 284A. By inserting the medical device into the immersion container 284, the medical device 120 can be moistened or lubricated with the fluid transferred from the fluid container 244 into the immersion container 284 through the first conduit 286 and the third conduit 288.

[0070] To use the wetting system 240, the user can first spike the second port 244B with the spike 250. With the stopper 290 on the third conduit 288 in the closed position, fluid can begin to flow from the fluid container 244 through the first conduit 286 into the reservoir 246. To fill the immersion container 284, the stopper 290 can be moved to the open position, thus allowing fluid to flow into the immersion container 284 through the third conduit 288. In this way, the immersion container 284 can be at least partially filled with fluid from the fluid container 244. With the stopper 290 in the open position, the flow of fluid from the fluid container 244 into the reservoir 246 can be reduced or stopped. Once the immersion container 284 is filled with the desired amount of fluid (e.g., to the desired level of the immersion container 284), the stopper 290 can be moved to the closed position, thus stopping the flow of fluid into the immersion container 284. With the stopper 290 in the closed position, fluid from the fluid container 244 can flow into the reservoir 246 without the fluid being diverted back to the immersion container 284. The fluid contained in the reservoir 246 can be used by the medical device 20, for example, to supply fluid to target tissue and / or to clean the lens of an imaging device. As described above, for example, the second conduit 278 can be fluidically coupled to the reservoir 246 and one or more parts of the medical device 20. The second conduit 278 can facilitate the flow of fluid from the reservoir 246 into the medical device 20.

[0071] With the immersion container 284 at least partially filled with fluid, the medical instrument 120 can be inserted into the immersion container 284 through the first open end 284A. In this way, the medical instrument 120 can be wetted or lubricated. The lubricated medical instrument 120 can then be inserted into the patient and / or into the working channel of the medical device 20, for example, through the opening 34 (shown in Figure 1).

[0072] Figure 5 shows another wetting system 340. The wetting system 340 may include a fluid container 344 and an immersion container 384. The fluid container 344 may have any or all of the features of the fluid container 144 described with reference to Figure 2 and / or the fluid container 244 described with reference to Figure 4. For example, the fluid container 344 may have a first port 344A and a second port 344B. One or both of the first port 344A and the second port 344B may have any or all of the characteristics described above with respect to the first port 144A and the second port 144B in Figure 2 and / or the first port 244A and the second port 244B in Figure 4. Although reservoirs similar to reservoirs 146 and 246 are not shown in Figure 5, it will be understood that the wetting system 340 may also include a reservoir (having any of the characteristics of reservoirs 146 and 246) coupled to the fluid vessel 144 (for example, via the first port 344A).

[0073] The immersion container 384 may be fluidically connected to the fluid container 344 via a conduit 386. For example, the first end 386A of the conduit 386 may be connected to the first (bottom) end 384B of the immersion container 384. The immersion container 384 may be similar to a small cup and may have any preferred shape (e.g., conical / frustoconical, bowl-shaped, cylindrical, etc.). As shown in Figure 5, the bottom end 384A of the immersion container may have approximately the same diameter / width as the conduit 386. Alternatively, the bottom end 384A of the immersion container 384 may be wider than the conduit 386. The bottom end 384A of the immersion container 384 may have an opening, as a result, the fluid may flow through the conduit 386 and through the opening in the bottom end 384A into the immersion container 384. In some examples, the opening in the bottom end 384A may extend across the entire diameter / width of the bottom end 384A. Alternatively, the opening at the bottom end 384A may extend only over a portion of the bottom end 384A. The opening at the bottom end 384A may have the same width as the lumen width of the conduit 386. The conduit 386 may be a separate element from the immersion vessel 384 and may be attached to the bottom end 384A of the immersion vessel 384. Alternatively, the conduit 386 may be coupled to the side of the immersion vessel 384, and the side wall of the immersion vessel 384 may have an opening for fluidly coupling the immersion vessel 384 to the conduit 386.

[0074] The immersion container 384 may have a second (upper) end 384B opposite the bottom end 384A. The second end 384B may be at least partially open (e.g., open across the diameter / width of the second end 384B). In some configurations, the second end 384B may include a removable cap or top configured to open and close over the opening of the second end 384B. For example, a user may open or remove the cap or top and insert the medical instrument 120 into the immersion container 384. Once the medical instrument is removed from the immersion container 384, the user may then close or replace the cap or top to prevent leakage from the immersion container 384. As shown in Figure 5, the walls of the immersion container 384 may be tapered radially outward from the bottom end 384A towards the second end 384B. However, such shapes are illustrative, and the immersion container 384 may have any preferred shape.

[0075] The second end 386B of the conduit 386 may include a needle 350 configured for insertion into the second port 344B, thus enabling fluid flow between the fluid container 344 and the immersion container 384. In some embodiments, the second port 344B may include self-sealing silicone configured to be punctured multiple times by the needle 350 without leakage. For example, the second port 344B may be configured similarly to the partition of an injection port commonly used in chemotherapy treatments. In other configurations, the needle 350 may be configured similarly to and / or have the properties of either the spike 150 and / or the spike 250. In such configurations, the second port 344B may have the properties of either the second port 144B and / or the second port 244B.

[0076] When the immersion container 384 is fluidically connected to the fluid container 344 via the conduit 386, fluid may begin to flow into the immersion container 384. The immersion container 384 may begin filling according to the principle of a connecting pipe. For example, the immersion container 384 may begin filling to the same level as the fluid in the fluid container 344. In this way, the fluids in both the immersion container 384 and the fluid container 344 may have the same fluid level.

[0077] The immersion container 384 may be detachably coupled to the fluid container 344 via a coupling 392. The coupling 392 may have any or all of the properties of the coupling 292 described above with respect to Figure 4. For example, the coupling 392 may be a clip or clamp configured to couple the immersion container 384 to the fluid container 346. In some embodiments, the coupling 392 may be detachably attached to the fluid container 344 and / or the immersion container 384 in Figure 4. In other embodiments, the coupling 392 may be fixedly coupled to the immersion container 384 and detachably coupled from the fluid container 344. In further embodiments, the coupling 392 may be fixedly connected to the fluid container 344 and detachably coupled from the immersion container 384. In some embodiments, the coupling 392 may include an adhesive or tacky material so that the coupling 392 can adhere to the fluid container 344. For example, either or both of the coupling 392 or the fluid container 344 may include an adhesive material.

[0078] The immersion container 384 can be coupled to the fluid container 344 at any location on the fluid container 344 (e.g., on the side of the fluid container 344). For example, the immersion container 384 can be positioned along the side of the fluid container 344 according to the current fluid level in the fluid container 344 and / or a desired fluid level within the immersion container 384. For example, the immersion container 384 can be positioned along the side of the fluid container 344 such that the second end 384B of the immersion container 384 is above the level of fluid contained in the fluid container 344, and the bottom end 384A is below the level of fluid contained in the fluid container 344. Thus, according to the principle of a connecting pipe, the fluid flows into the immersion container 384 but does not overflow from the second end 384B of the fluid immersion container 384. If the second end 384B is below the level of fluid contained in the fluid container 344, the immersion container 384 may be overfilled / overflow.

[0079] As the fluid level in the fluid container 344 increases or decreases (for example, by injecting fluid into the fluid container 344 via the first port 344A), the immersion container 384 can be repositioned on top of the fluid container 344. Specifically, as the fluid level in the fluid container 344 decreases, the immersion container 384 can be moved downward on top of the fluid container 344 so that the immersion container 384 is filled, as described above. As the fluid level in the container increases, the immersion container 384 can be moved upward relative to the fluid container 344 to prevent leakage. Thus, a desired fluid level in the immersion container 384 can be maintained.

[0080] Once the immersion container 384 is filled to the desired level, the medical device 120 can be inserted into the immersion container 384. For example, the distal end of the medical device 120 can be inserted into the immersion container 384 so that the distal end of the medical device 120 is moistened or lubricated. With the medical device 120 moistened, it can be inserted into the patient or medical device 20, for example, through the opening 34 (shown in Figure 1).

[0081] Figure 6 illustrates an alternative wetting apparatus 440. The wetting apparatus 440 may include a fluid container 444 and an immersion section 484. The fluid container 444 may have any or all of the features described above with respect to the fluid container 144 in Figure 2, the fluid container 244 in Figure 4, and / or the fluid container 344 in Figure 5, except as described below. For example, the fluid container 444 may be a bag or a bottle.

[0082] The immersion portion 484 may be formed integrally with the fluid container 444. In some examples, the immersion portion 484 may be formed from the same material as the fluid container 444. In other examples, the immersion portion 484 may be formed from a different material than the fluid container 444. As shown in Figure 6, the outer wall 484A of the immersion portion 484 may extend along at least a portion of the side surface of the fluid container 444. In some examples, the outer wall 484A of the immersion portion 484 may extend along the entire length of the side surface of the fluid container 444, for example, between the top and bottom of the fluid container 444. The immersion portion 484 may have an opening 484B at its upper end.

[0083] The wall 445 of the fluid container 444 may separate the immersion section 484 from the fluid container 444. For example, the wall 445 may define one of the walls of the fluid container 444 and the immersion section 484. The wall 445 does not have to extend along the entire length of the fluid container 444 so that an opening 449 is formed to allow fluid communication between the fluid container 444 and the immersion section 484. For example, as shown in Figure 6, the wall 445 may terminate above the bottom of the fluid container 444 / immersion section 484 so that the opening 449 is formed below the wall 445. Alternatively, the wall 445 may include an opening formed above the bottom of the wall 445. In some examples, the wetting device 440 may be a bag, and the wall 445 may be formed by fusing or joining the walls of the bag together. For example, the wall 445 may be formed by fusing two sides of the wetting device 440 using heat. Alternatively, the wall 445 may be formed using an adhesive. In this way, the two sides of the wetting device 440 can be fused or formed together to form the fluid container 444 and the immersion section 484. Alternatively, the fluid container 444, the immersion section 484, and the wall 445 can be formed by any suitable method (e.g., molding, removal manufacturing, or additive manufacturing).

[0084] In some examples, the fluid container 444 optionally includes a stopper 490. The stopper 490 may be located on or within the fluid container 444 to control the flow of fluid between the fluid container 444 and the immersion section 484. The stopper 490 may be a clamp, valve, clip, or any other mechanism used to control the flow of fluid from the fluid container 444 to the immersion section 484. In some examples, the stopper 490 may be a one-way valve configured to allow the flow of fluid to the immersion section 484 and to prevent the flow of fluid from the immersion section 484 to the fluid container 444. In examples having a stopper 490, the outer wall 484A may extend along a portion of the side of the fluid container 444 such that the opening 484B of the immersion section 484 is below the top surface of the fluid container 444.

[0085] In a first closed configuration, the stopper 490 may be configured to prevent the flow of fluid from the fluid container 444 into the immersion section 484. In a second open configuration, the stopper 490 may be configured to allow the flow of fluid from the fluid container 444 into the immersion section 484. In some examples, the stopper 490 may be configured for manual operation (opening / closing) by the user. In other examples, the stopper 490 may be operated electrically or via a control module (not shown). Thus, the stopper 490 may be configured to open and / or close using an electrical input.

[0086] In some examples, the port 444A of the fluid container 444 may be configured to be punctured by a spike 450 at the end of the conduit 486. Although not shown in Figure 6, the conduit 486 may be coupled to a reservoir having any of the reservoir characteristics described above. The fluid from the reservoir may be used during the medical procedure as described above. Alternatively, the reservoir may be omitted, and the fluid from the fluid container 444 may be delivered to the medical device 20 via the conduit 486 for use during the procedure.

[0087] To fill the immersion section 484 with fluid, the stopper 490 can be opened, thus allowing fluid to flow into the immersion section 484. The immersion section 484 is filled according to the principle of a connecting pipe. For example, the immersion section 484 can be filled until the fluid level in the immersion section 484 is the same as the fluid level in the fluid container 444. The amount of fluid in the immersion section 484 can be controlled, for example, via the stopper 490. For example, if the user wants less fluid in the immersion section 484, the stopper 490 can be closed, thus stopping the flow of fluid between the fluid container 444 and the immersion section 484. In this way, the amount of fluid in the immersion section 484 can be controlled. Alternatively, if the stopper 490 is omitted, fluid may flow automatically into the immersion section 484 and fill it up to the level of fluid in the fluid container 444. In such an alternative, the outer wall 484A of the immersion section 484 may extend along the side of the fluid container 444 such that the opening 484B of the immersion section 484 is above the liquid level in the fluid container 444. In this way, the fluid in the immersion section 484 can be filled to the same level as the fluid in the fluid container 444 without overflowing.

[0088] To lubricate the medical device 120, it may be inserted through the opening 484B of the immersion section 484. For example, the medical device 120 may be at least partially inserted into the immersion section 484 so that it is moistened. Once the medical device is moistened, it may be inserted into the patient or through the working channel of the medical device 20 (for example, through the opening 34), as described above with respect to Figure 1.

[0089] Figures 7A–7C illustrate alternative wetting systems 540 in the first configuration (Figure 7A), the second configuration (Figure 7B), and the third configuration (Figure 7C). The wetting system 550 includes a fluid vessel 544, a movable valve 548, and an immersion vessel 584. The fluid vessel 544 may have any or all of the features of the fluid vessel 144 described with reference to Figure 2, the fluid vessel 244 described with reference to Figure 4, the fluid vessel 344 described with reference to Figure 5, and / or the fluid vessel 444 described with reference to Figure 6. The immersion vessel may have any or all of the features of the immersion vessel 284 described with reference to Figure 4 and / or the immersion vessel 384 described with reference to Figure 5.

[0090] In some configurations, the immersion container 584 may include an opening 584A configured to receive at least a portion of a medical device (not shown). For example, during use, a portion of a medical device (not shown) may be inserted into the immersion container 584 through the opening 584A. Not shown, in some configurations, the immersion container 584 may be fixedly or detachably coupled to a fluid container 544, for example, via a coupling. For example, the coupling may have any or all of the characteristics of the coupling 292 and / or the coupling 392 described with reference to Figure 4 and / or Figure 5.

[0091] The first conduit 586 may extend between the fluid container 544 and the valve 548. Although not shown in Figures 7A to 7C, the first conduit 512 may have spikes or needles (having either of the spike or needle characteristics described above) or other structures for selectively connecting the first conduit 512 to the fluid container 544 (for example, to a port of the fluid container 544).

[0092] The second conduit 542 may extend from the valve 548 (for example, radially outward from the valve 548). Although not shown in Figures 7A to 7C, the second conduit 542 may be connected to a reservoir having any of the reservoir characteristics described above. The fluid from the reservoir may be used during medical procedures as described above. Alternatively, the reservoir may be omitted, and the second conduit 542 may extend to a medical device, such as the medical device 20 in Figure 1, and be fluidically connected to it.

[0093] The third conduit 588 may extend between the valve 548 and the immersion container 584 and connect them fluidly. As described above with respect to the immersion container 384, the immersion container 584 may have an opening connected to the third conduit 588 so that the third conduit 588 is in fluid communication with the third conduit 588. For example, as described above, the bottom of the immersion container 584 may include an opening connected to the third conduit 588. In an alternative example, the immersion container 584 may be omitted, and the third conduit 588 may be terminated at a free end. A separate cup, bottle, or other type of container may be filled with fluid flowing through the free end of the third conduit 588.

[0094] The valve 548 may include a lumen 551 that can define a path through which fluid can flow. As shown in Figures 7A–7C, the valve 548 may have a substantially circular or spherical shape, and the lumen 551 may have a curved path. The lumen 551 may extend from a first opening 551A on the surface of the valve 548 to a second opening 551B, also on the surface of the valve 548. In some examples, the central angle between the first opening 551A and the second opening 551B may be about 120 degrees.

[0095] In the first configuration, as shown in Figure 7A, each end of the lumen 551 can be aligned with the first conduit 512 and the second conduit 542. For example, the first opening 551A can be aligned with the first conduit 586, and the second opening 551B can be aligned with the second conduit 542. Thus, the valve 548 can be configured to allow fluid to flow from the fluid container 544 through the first conduit 586 and through the lumen 551 to the second conduit 542. In this way, fluid from the fluid container 544 can be delivered to a medical device (e.g., medical device 20). In the first configuration, since the lumen 551 is not aligned with the third conduit 588, fluid flow to the immersion container 584 is not permitted.

[0096] In a second configuration of the valve 548, as shown in Figure 7B, the lumen 551 can be aligned with a second conduit 542 and a third conduit 588. For example, the first opening 551A can be aligned with the second conduit 542, and the second opening 551B can be aligned with the third conduit 588. In the second configuration, fluid can be allowed to flow between the immersion vessel 584 and a reservoir or medical device (e.g., medical device 20). Since the immersion vessel may be above 584 and / or there may not be any pressure to move the fluid upward from the reservoir or medical device into the immersion vessel 584, in the second configuration, the fluid can flow from the immersion vessel 584 through the third conduit 588, through the lumen 551, and through the second conduit 542. In this way, the immersion vessel 584 can be emptied. In the configuration shown in Figure 7B, the fluid flow from the fluid container 544 can be stopped (not allowed).

[0097] In a third configuration of valve 548, as shown in Figure 7C, the lumen 551 can be aligned with the first conduit 512 and the third conduit 588. For example, the first opening 551A can be aligned with the third conduit 588, and the second opening 551B can be aligned with the first conduit 586. Thus, fluid can flow between the fluid container 544 and the immersion container 584. When the fluid level in the immersion container 584 is lower than the fluid level in the fluid container 544, the fluid can flow from the fluid container 544 into the first conduit 586, through the lumen 551, through the third conduit 588, and into the container 584, according to the principle of the connecting pipe as described above. In this way, the immersion container 584 can be filled with fluid from the fluid container 544.

[0098] Valve 548 may be configured to transition or move between each configuration (e.g., a first configuration, a second configuration, and a third configuration) by various mechanisms. For example, rotation of valve 548 (e.g., clockwise or counterclockwise) may transition valve 548 between each configuration. Additionally or alternatively, valve 548 may include one or more buttons, actuators, levers, etc., configured to transition valve 548 to each configuration. In some examples, valve 548 may be electrically operated. For example, valve 548 may be configured to transition between each configuration via an electrical input. The arrangements and types of valve 548 described above are merely illustrative, and as stated above, any suitable type of valve may be used to fluidically connect the conduits. Valve 548 and / or conduits 542, 586, 588 may include one-way valves to prevent fluid from flowing in directions other than those described herein. In some examples, valve 548 may be a two-way valve, and the second configuration in Figure 7B may be omitted.

[0099] An immersion container 584 may be filled to lubricate a medical device (not shown). For example, a valve 548 may be moved to a third configuration (Figure 7C) so that fluid from the fluid container 544 flows into the immersion container 584. Once the immersion container 584 contains a desired volume of liquid, the valve 548 may be moved to a first configuration (Figure 7A). Using the fluid in the immersion container 584, a medical device (not shown, but having any of the features of medical device 120) may be inserted into or immersed in the immersion container 584 so that a portion of the medical device is wet or lubricated. Once a desired length or portion of the medical device is wet, the medical device may be inserted into a patient and / or inserted through a working channel of a medical device (e.g., medical device 20 in Figure 1).

[0100] To fill a reservoir (not shown, but having any of the features of any of the reservoirs shown and described above), or to allow fluid to flow into a medical device 44a (e.g., medical device 20 in Figure 1), the valve 548 may be transitioned to a first configuration or may remain in a first configuration.

[0101] In some cases, the fluid from the immersion container 584 may need to be drained, or may be desired to be drained. In such cases, the valve 548 may be converted to a second configuration (Figure 7B). In the second configuration, the fluid is allowed to flow from the immersion container 584 through the valve 548 to, for example, a medical device and / or into a reservoir or disposal container.

[0102] Valve 548 can be moved multiple times between each configuration to achieve the desired result. For example, valve 548 can be moved from the first configuration (Figure 7A) to the third configuration (Figure 7C) once or more throughout the procedure to fill and / or replenish the immersion container 584. Similarly, valve 548 can be moved to the second configuration (Figure 7B) once or more throughout the procedure to drain the immersion container 584, for example. Once the immersion container 584 is drained, new fluid can be replenished in the immersion container 584 by moving the valve to the third configuration (Figure 7C). In this way, new fluid can be periodically supplied to the immersion container 584 so that medical devices (not shown) can be lubricated or moistened with the new fluid.

[0103] Figures 8A and 8B illustrate a front view (Figure 8A) and a side view (Figure 8B) of a portion of an exemplary wetting system 640. The wetting system 640 may include a fluid reservoir 681 coupled to a wetting module 663. A conduit 686 may extend from the top surface (or another surface) of the wetting module 663. The conduit 686 may be fluidically coupled to a fluid source (not shown). The fluid source may be a fluid container such as one of the fluid containers previously discussed herein (e.g., fluid container 144, fluid container 244, fluid container 344, fluid container 444, and / or fluid container 544). In some examples, the fluid source may be a pressurized fluid source.

[0104] Conduit 686 may be coupled to adapter 657. Adapter 657 may be configured to allow fluid flow from a fluid source (a) through conduit 686 to the wetting module 663, and (b) through a second conduit 642. Not shown, the second conduit 642 may be fluidically coupled to a medical device (e.g., medical device 20 in Figure 1) or a reservoir (having any features of any reservoir disclosed herein). In some examples, adapter 657 may be configured to allow fluid flow through other conduits (not shown) to adapt to fluid flow to multiple medical devices, for example.

[0105] The wetting module 663 may include a nozzle arm 665 and a base 669. The nozzle arm 665 and the base 669 may be connected via a bridge portion 667. For example, the nozzle arm 665 may extend laterally from the bridge portion 667 in a first direction. The base 669 may extend laterally from the bridge portion 667 in the same first direction. The nozzle arm 665 may be positioned above the base 669 and spaced apart from the base 669. In this way, a gap 671 may be formed between the nozzle arm 665 and the base 669. The bridge portion 667 may form a first side of the gap 671. Thus, the gap 671 may be C-shaped. For example, the gap 671 may be defined by the bottom surface of the nozzle arm 665, the top surface of the base 669, and the bridge portion 667. The gap 671 may be open on three sides, thus allowing the user to access the gap 671 from at least three sides of the moist module 663 (e.g., a first side, a second side, and a third side). In this way, the gap 671 may be configured to receive a medical instrument 120 (shown in Figure 8B).

[0106] In some examples, the absorbent material 673 may be placed between the nozzle arm 665 and the base 669, for example, in the gap 671. The absorbent material 673 may be a sponge-like material configured to retain moisture, for example. In this way, as fluid is delivered from the nozzle arm 665, any excess fluid can be retained by the absorbent material 673. In some examples, the absorbent material 673 may be located on the underside of the gap 671 (for example, on the upper surface of the base 669). In other examples, the absorbent material 673 may be on multiple sides of the gap 671, for example, along the surface of the bridge portion 667 and / or along the underside of the nozzle arm 665.

[0107] The nozzle arm 665 may be configured to supply fluid through a gap 671. For example, the nozzle arm 665 may be configured to spray and / or drip fluid through the gap 671. Excess fluid may be captured by a receptor 675 located in the base 669. In some examples, an absorbent material 673 may cover the receptor 675. The receptor 675 may be conical or funnel-shaped. For example, excess fluid from the nozzle arm 665 may be captured by the receptor 675. The receptor 675 may be fluidically coupled to a reservoir 681. The reservoir 681 may be fixedly or detachably coupled to the wetting module 663. In some examples, the reservoir 681 may be detachable so that, for example, the reservoir 681 may be emptied and / or replaced. In other examples, the reservoir 681 may be fixedly coupled to the wetting module 663. In such an example, reservoir 681 may include a port or drain so that reservoir 681 can be emptied or drained.

[0108] The wetting module 663 may include a controller 677 located on the rear surface of the wetting module 663. The controller 677 may be configured for one or more modes of fluid flow. For example, the controller 677 may, among other modes, control the amount of fluid delivered (e.g., sprayed or dripped), the intensity (e.g., pressure) of the fluid delivery, and the temperature of the fluid. In some examples, the controller 677 may be an on / off switch configured to allow or stop the fluid flow through the nozzle arm 665. The controller 677 may include an actuator (e.g., a knob, lever, button, switch, etc.). In some examples, the controller 677 may be operated manually. For example, a user may manually adjust the controller 677. In other examples, the controller 677 may be operated via electrical inputs. For example, a computer (not shown) may be configured to adjust the controller 677. In other examples, as described later, the controller 677 may automatically activate the flow in the nozzle arm 665 (e.g., based on sensing that a medical device 120 is below the nozzle arm 665).

[0109] As shown in Figure 8B, during use, a portion of the medical device 120 may be inserted through the gap 671. As the medical device 120 moves through the gap 671 and under the nozzle arm 665, fluid may be delivered from the nozzle arm 665 onto the surface of the medical device 120. The fluid may be sprayed or dripped onto the surface of the medical device 120. In this way, the surface of the medical device 120 may be moistened or lubricated. Additionally or alternatively, the medical device 120 may be moved along or through the absorbent material 673 so that the absorbent material 673 moistens the surface of the medical device 120.

[0110] Once the fluid is applied to a desired portion of the medical instrument 120 so that the medical instrument 120 is wetted or lubricated, the medical instrument 120 may be removed from the wetting module 663 and inserted into the patient or inserted through the working channel of a medical device (e.g., medical device 20 in Figure 1).

[0111] In some examples, the wetting module 663 may include one or more sensors 679. One or more sensors 679 may be motion sensors configured to detect, for example, when a medical device 120 passes through the gap 671. One or more sensors 679 may be electrically coupled to a controller 677. For example, when the medical device 120 passes through the gap 671, the sensor 679 may provide an electrical signal to the controller 677 to start the nozzle arm 665 to deliver fluid. When the medical device 120 is removed from the gap 671, the sensor 679 may be configured to provide an electrical signal to the controller 677 to stop the nozzle arm 665, and as a result, no more fluid is delivered.

[0112] Figure 9 illustrates a hoop 700. The hoop 700 includes a loop-shaped tube 701 held in place by a plurality of clips 702. The first end 701A of the tube 701 may include an adapter 704. The adapter 704 may define one or more lumens that can fluidly communicate with the lumens of the tube 701. The adapter 704 may be configured to be detachably or fixedly coupled to a fluid source (not shown). For example, the adapter 704 may include a shaft 705 and an arm 706. The arm 706 may extend substantially perpendicularly from the shaft 705. Alternatively, the arm 706 may extend from the shaft 705 at any preferred angle. The adapter 704, including the shaft 705 and the arm 706, may have a "T" shape. The arm 706 and the shaft 705 may each have lumens extending through them. The lumens of the arm 706 and the shaft 705 may fluidly communicate with each other. The arm 706 may include an opening 706A at its free end (the end of the arm not connected to the shaft 705). The opening 706A may provide access to the lumens of the arm 706.

[0113] The opening 706A may be selectively coupled to a fluid source (not shown). In some examples, the fluid source may be a syringe of fluid. The syringe may be coupled to the arm 706 of the adapter 704, so that water can be injected into the lumen of the adapter 704, and thus into the tube 701. In some examples, the adapter 704 may include a seal 707 at at least one end of the adapter 704. The seal 707 may be configured to prevent fluid from flowing out of the tube 701. In some configurations, the seal 707 may include an opening through which at least a portion of a medical device can extend. For example, the seal 707 is located between the arm 706 and the opening side of the shaft 705. The seal 707 may extend around the medical device 720 or at least partially enclose the medical device 720. In this way, the seal 707 may form a liquid-tight seal around the medical device 720.

[0114] 701 may include a cap 703 fixedly or detachably coupled to the second end 701B of the tube 701. The cap 703 may be configured to prevent fluid from leaking out of the tube 701. In this way, the medical device 720 can be wetted or lubricated before being removed from the tube 701. The cap 703 may include a pressure relief valve 709. For example, when a liquid is injected into the tube 701, the pressure relief valve 709 can release air trapped inside the tube 701. Once a desired volume of liquid has been injected into the tube 701, the cap 703 may be removed, and the wetted or lubricated medical device 720 can be removed from the tube 701.
