Abstract

A tube assembly includes a tube for placement within a patient. The tube includes a lumen, a tip secured to a distal end portion of the tube, and a mounting supporting a camera and at least two fiber optic filaments. The mounting extends within the distal end portion of the tube. The tip may be secured at least partially within the lumen or abut and partially extend into the lumen, and the mounting may extend within the lumen. A camera and at least two fiber optic filaments may be supported by the mounting. The tip may be at least partially dissolvable. Once the assembly is positioned within the patient, the dissolvable portion of the tip is dissolved by gastrointestinal fluids thereby providing an unobstructed distal tube end for material to flow through.

Description

TUBE ASSEMBLIES
[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63/109,473, filed November 4, 2020, the disclosure of which is incorporated herein by reference.
FIELD OF THE INVENTION
[0002] This document relates generally to tube assemblies, and more specifically with temporary tubes for placement in a patient and tips used therewith.
BACKGROUND OF THE INVENTION
[0003] In the course of healthcare, temporary tubes are placed into the body. Such tubes placed internally within the body are generally supplied with a tip, sometimes referred to as a bolus, at least in part to facilitate the insertion process. Tips facilitate insertion by having an arcuate shape along at least a portion of an outer surface. Generally, the outer surface may have a rounded or bullet shaped distal portion which enhances gliding and bending along curved, fragile surfaces of the nasal airway, the pharynx, the esophagus, stomach and/or intestines for example.
[0004] Accommodating the need to facilitate the insertion process, however, can result in a design compromise. After insertion, a tip designed to facilitate insertion could prevent unobstructed flow of material(s) passing out of the end of the tube. A partial or complete change away from axial material or fluid flow is required to exit via a pathway around or through the tip. Due to this necessary change of direction, the tip may interfere with such flow and thus contribute to complications associated with the tube, for example, clogging. Accordingly, a need exists for a tube assembly including a tip designed to facilitate the insertion process and to limit any contribution to complications associated with the tube.

[0058] Reference will now be made in detail to the present described embodiments of the invention, examples of which are illustrated in the accompanying drawing figures, wherein like numerals are used to represent like elements.
DETAILED DESCRIPTION
[0059] Reference is now made to Figure 1 which partially illustrates a tube assembly 10 for placement of an enteral tube in a patient (P). Enteral tubes include, but are not limited to, nasogastric tubes, nasoduodenal tubes, oral gastric tubes, oral duodenal tube, and feeding tubes located distal to the duodenum. Alternatively, the tube assembly 10 may be utilized to place endotracheal tubes which are designed to reside in the patient’s trachea and enter the body through the mouth or the nose.
[0060] In the described embodiment, the tube assembly 10 includes a tube 12 having a distal end portion (generally designated numeral 14) for placement within the patient (P), and a tip 16 supported at the distal end portion of the tube. At least two optical fibers or fiber optical filaments 18, 20 extend through a lumen of the tube 12 and guide light from an external light source onto an area of the gastrointestinal, or GI, tract adjacent a camera 22. In the described embodiment, the external light source is a high intensity light emitting diode or LED which may be positioned adjacent an end of the at least two optical fibers 18, 20 utilizing a heat shrink sleeve or otherwise as is known in the art. Of course, other light sources may be utilized in alternate embodiments.
[0061 ] As shown in Figure 1, distal ends of the at least two optical fibers 18, 20 and the camera 22 are positioned at least partially within the tip 16. In the described embodiment, two optical fibers 18, 20 are utilized and the camera 22 and optical fibers are recessed a distance from an end or apex of the tip 12. Even more, the optical fibers 18, 20 are recessed farther than the camera 22 within the tip 12 to avoid light contamination across a lens of the camera. In other words, the optical fibers 18, 20 are supported such that a distal end of the camera 22 extends distally farther than distal ends of the optical fibers.
[0062] At least a distal portion of the tip 16 is generally round or dome-shaped to facilitate passage through the gastrointestinal tract. In the described embodiment, the dome-shaped distal portion 24 abuts an end of the tube 12, as shown in Figure 1. Alternatively, the tip may be formed such that a dome-shaped distal portion may be positioned a distance from the tube end 26. For example, an alternate tip embodiment could include a cylindrical section positioned between the tube end and the dome-shaped distal portion as described in more detail below.
[0063] A central aperture 28 defined by the dome-shaped distal portion 24 exposes the camera 22 and the optical fibers 18, 20 to ambient air or the gastrointestinal tract when inserted in the patient (P). In the described embodiment, the central aperture 28 is generally triangular in shape and vertices of the triangular shaped central aperture generally conform to different radii of the camera 22 and optical fibers 18, 20 as best shown in Figure 2.
[0064] As also shown in Figure 2, the central aperture 28 is sized such that vertices of the aperture extend beyond radii of the camera 22 and optical fibers 18, 20. In other embodiments, however, the central aperture 28 may be smaller such that the dome-shaped portion 24 of the tip 12 at least partially covers the camera 22 and/or optical fibers 18, 20. In other words, the radius of one or more of the central aperture vertices may be less than the radius of the camera 22 and/or optical fibers 18, 20.
[0065] While the term camera is utilized herein in a general sense, the camera 22 includes a housing 30 and an aperture 32 covered by a lens 34 as is known in the art. In the described embodiment, a cable 42 (shown in Figure 4) is connected to the camera 22 and extends through a rear wall 38 of the housing 30. In other embodiments, the camera may be wireless utilizing radio frequency transmitters/receivers, near field, or similar technology. Even more, the cable 42 may include a connector at its distal end for connection to a mating connector mounted on the rear wall 38 of the camera housing 30. Either way, images from the camera are provided external to the patient (P) whether via the cable 42 extending within/along the tube 12, or wirelessly, as will be described in more detail below. Power is also provided to the camera 22 via the cable 42 when utilized.
[0066] In the described embodiment, the camera 22 is positioned at least partially in the tip 16 and is removable through the lumen of the tube 12 after placement of the tube in the patient (P). Alternatively, the camera 22 may initially be positioned a sufficient distance from the dome-shaped portion 24 of the tip 12 to reside entirely within the lumen of the tube 12. The camera 22 may be a single use disposable camera or a multiple use camera suitable for cleaning and/or sterilization. In addition, the camera 22 may be contained in a disposable sheath (not shown) having an optically clear end positioned adjacent the camera lens 34. After placement of the tube 12 and removal of the camera 22, the sheath would be discarded and a new sheath utilized in a subsequent use of the camera.
[0067] As shown in Figure 3, industry standard connectors (not shown) may be located at a proximal end portion 36 of the tube 12. An electrical connector 38, for example, may be located separate from the tube 12 or attached at the proximal end portion thereof. The wiring harness 42 runs from the camera 22 to the proximal end portion 36 of the tube 12 where the connector 38 is located. In addition, a flexible, stylet 46 may be used via placement within the lumen of the tube 12 at the proximal end portion 36.
[0068] In the described embodiment, the camera 22, and fiber optic filaments 18, 20 are connected to an enclosure 88 located external to the tube 12 as shown schematically in Figure 4. As shown, the enclosure 88 contains a power supply or source 40, signal processing electronics 86 for operation of the camera 22, a light source (e.g., LEDs) 44, and a video display 90. The display 90 is attached to the enclosure 88 and processor 42 via a video output cable 92 for displaying images from the camera 22. In an alternate embodiment, the display or screen may be remotely positioned including, for example, on a handheld computing device, a smart phone, or other remote display that receives information from the processor via WIFI, Bluetooth, or other transmit and receive mechanisms. Even more, a recording device for recording the images from the camera may be used or at least portions of the signal processing electronics (e.g., a processor) may be located adjacent to the camera 22 in the distal end portion 14 of the tube 12 in alternate embodiments.
[0069] In the described embodiment, the camera cable 42, the stylet 46, and the at least two optical fibers 18, 20 extend centrally within the tube 12. In various alternate embodiments, one or more of the camera cable 42, stylet 46, and/or optical fibers 18, 20 may traverse the lumen of the tube 12 and/or be embedded within a side wall of the tube. The stylet 46 is provided to stiffen and guide the tube 12 during initial insertion. In the described embodiment, a nitinol wire (aka “a memory wire”) is used to create a deflection at the distal end portion 14 of the tube 12. Using the images provides by the camera 22, steering only requires the tip 16 of the tube 12 to bend in one direction since the tube can be rotated.
[0070] The nitinol material has the physical property of existing in one shape under normal circumstances, but will transform to a different configuration when an electrical voltage or current is applied thereto. For this application, the nitinol stylet would have a straight configuration as its norm or baseline. If the clinician desires the distal end portion 16 of the tube 12 to turn, an electrical current/voltage from the power supply 40 is applied to the nitinol wire and an end of the nitinol wire will take on its alternate or memory configuration of a bend. To do so, the clinician activates a switch or potentiometer (not shown) to send a current/voltage to the nitinol stylet 46 creating the variable deflection of the distal end portion 14.
[0071] In one alternate embodiment, two nitinol wires may be utilized with memory bends in differing directions to provide alternative steering options. In another alternate embodiment, the fiber optic filaments 18, 20 may be used to generate deflection of the distal end portion 14 of the tube 12 for steering.
[0072] In addition to the nitinol stylet 46 described, steering of the tube 12 may alternatively be provided by a two component stylet in which one wire remains stationary and the other moves linearly against the first wire. The stationary and moving wires are rigidly attached only at their proximal ends. An outer sheath or a series of connectors binds the two components together while allowing linear slide of the moving component. Thus, a deflection is created at the proximal end portion of the tube as the moving wire is advanced or withdrawn relative to the stationary wire.
[0073] In the described embodiment, the stylet 46 is attached in an aperture (not shown) in a proximal portion of a mounting 52 in a manner known in the art. In this manner, the stylet 46 may be used to withdraw the mounting 52, including the camera 22 and at least two optical fibers 18, 20, through the lumen of the tube 12 after placement in the patient (P). In this embodiment, the cable 42 for video signals as well as power would run parallel to or within the stylet 46. The cable 42 and stylet 46 may further be contained within a sheath which also includes or integrates with the camera 22.
[0074] As best shown in Figure 5, the camera 22 and distal ends of the at least two optical fibers 18, 20 are secured in relative positions within recesses or channels 48, 50 formed in the mounting 52. The recesses 48, 50 support the camera 22 and at least two optical fibers 18, 20 in a substantially triangular configuration.
[0075] As shown, the mounting 52 is generally cylindrical in shape to accommodate movement within the tube lumen. A groove or cutout 54 extends lengthwise along the mounting 52 and engages a corresponding ridge 56 as best shown in Figure 2. The ridge 56 is located within the tip 16, as shown in Figure 6, and extends at least partially along a portion or flange 60 of the tip 16 for properly orienting the mounting 52 relative the central aperture 28 of the tip 16. In this manner, the camera 22 and at least two optical fibers 18, 20 supported by the mounting 52 are oriented or aligned such that their triangular configuration aligns with the triangular central aperture 28 of the tip 16.
[0076] Returning to Figure 1, the mounting 52 is also shown proximally or distally located at least partially within the tip 16. A stop 58, shown in Figure 6, extends internally within the tip 16 and abuts the mounting 52 when the mounting is fully inserted thereby limiting an amount the mounting extends into the tip. In the described embodiment, the stop 58 partially defines the substantially central aperture 28 of the tip 16. Of course, the mounting 52 may extend varying distances into the tip 16 or may reside entirely within the lumen of the tube 12 as suggested above. The mounting 52 supporting the camera 22, and at least two optical fibers 18, 22 is releasably held in the tip 16 by a press or friction fit. In the described embodiment, the mounting 52 is partially inserted into the tip 16 at the time of manufacture and remains in this position until the tube 12 has been placed in its desired location within the gastrointestinal tract of the patient (P) as visually confirmed by the camera 22. Once positioned, the stylet 46 is pulled out of the tube 12 along with the mounting 52, camera 22, and at least two optical fibers 18, 20.
[0077] As shown in Figure 1, the tip 16 is secured to the distal end portion 14 of tube 12 by inserting or extending the portion or flange 60 of the tip 16 into the lumen of the tube 12. In the described embodiment, the flange 60 of the tip 16 is press or friction fit into the tube 12. Alternate embodiments ensure retention of the tip 16 by means of adhesives, the natural tackiness of the tip material, or other retention means known in the art. One or more ridges, rings, or other mechanical features known in the art may be positioned on a proximal portion of the tip 16 to provide retentive forces. Since a primary function of the tip 16 is tube insertion, the tip is made of a dissolvable material in the described embodiment.
[0078] In the described embodiment, the tip 16 is designed to remain intact to facilitate the insertion process and placement of the tube 12 and then dissolve away. This leaves an unobstructed distal opening in the tube 12 encompassing its full inner diameter and allowing fluid flow along the long axis of the tube without any change in direction. In order to dissolve away, the tip 16 comprises a material, or materials, which are soluble and suitable for human or animal consumption. One soluble material is a polymer marketed under the registered trademark Affinisol. Broadly speaking, any soluble material may be utilized. In addition to being soluble, the material or materials may include additional properties such as lubriciousness when exposed to a moist environment. More specifically, the tip material may be coated with a water activated lubricious coating to facilitate gliding during insertion.
[0079] As suggested above and best shown in Figure 1, the tip 16 is generally round or dome-shaped. In other words, the tip 16 includes a conical or bullet shaped distal contoured surface or face 24. In the described embodiment, an outer diameter of the tip 16 substantially corresponds to an outer diameter of the tube 12 creating a smooth outer surface at least at the butt joint. Limiting the outer diameter of the tip 16 in this manner enhances patient comfort and eases the insertion process particularly when moving through narrower portions of the gastrointestinal tract. While maintaining the outer diameter of the tip 16 to substantially correspond with the outer diameter of the tube 12 provides certain advantages, other embodiments may include an outer tip diameter that is larger than the outer diameter of the tube.
[0080] Even more alternate embodiments may utilize a partially dissolvable tip. For example, the flange 60 of the described tip 14, or portions thereof, may be dissolvable to ensure the tip is dislocated from the tube 12 leaving the unobstructed distal opening. The remaining portion of the tip 16 may not be dissolvable but would dislodge from the tube 12 and pass through the gastrointestinal tract of the patient (P). In other embodiments, varying portions of the tip may be dissolvable so long as the dissolvable portions are sufficient to ensure the tip is dislocated from the tube.
[00 1 ] Following placement of the tube 12, the tip 16 will reside in the gastrointestinal tract, typically, in the stomach (whether an enteral or gastrostomy tube) or small bowel. Both anatomic areas provide an aqueous environment which will lead to dissolution. In addition, fluids such as water or nutritional formulas moving through the tip central aperture/hole further expedite dissolution.
[0082] As illustrated in Figures 2 and 6, irrigation channels 62 are formed in or defined by the tip 16. Within the tip 16, fluid flow is obstructed from flowing out around the mounting 52 due to the tight fit between the mounting and the tip. Accordingly, the irrigation channels 62 provide the only pathway for fluids to flow. If the lens of the camera 22 becomes obscured by mucous or other material in the gastrointestinal tract, a fluid is placed into the tube lumen and directed across the camera lens via the irrigation channels 62. Further, if the development of an optical cavity is needed, air may be insufflated through the irrigation channels 62 using an irrigation fitting to enhance visualization.
[0083 ] As shown in Figure 7, end portions of the irrigation channels 62 include a surface 64 curved inward toward the central aperture 28 to duct fluid flow across distal ends of the camera 22 and fiber optic filaments 18, 20. The curved surface 64 utilizes capillary action or surface tension to direct the path of the fluid in the desired direction toward the camera 22. Further curvature along sidewalls 66 adjacent the camera 22 similarly direct the fluid flow toward the camera as best exemplified in Figure 2. Given the reliance on surface tension in the described embodiment, it is worth nothing that fluid flow for irrigation must be controlled to ensure the flow maintains contact with the irrigation channels along the desired path and does not simply spray straight out of the irrigation channels. In an alternate embodiment shown in Figure 8, a deflector 70 associated with each irrigation channel extends from a tip 68 to preclude fluid spray. As shown, an inner surface 72 of the deflector 70 is curved and substantially conforms to an inwardly curved surface 74 of end portions of the irrigation channels. As noted, the deflector 70 assures fluid flow across the camera 22. In such embodiments, an outer surface 76 of the deflector 70 may form a portion of the outer surface of the rounded tip.
[0084] In summary, numerous benefits result from a tube assembly 10 for placement in a patient (P) as illustrated in this document. The tube assembly 10 provides for tube placement with a direct method of visualization. In addition, the tube assembly 10 provides a sufficient amount of light within the pathway without excessive heat and provides for cleaning fluids and/or food debris from the camera lens to ensure proper visualization for the clinician during placement of the tube 12. Once positioned, the tube 12 is ready for fluid flow including water and/or enteral feeding formula. In certain embodiments, the tip 16 is dissolved and the lumen is sufficiently large to allow flow after removal of the camera 22 and fiber optic filaments 18, 20.
[0085] The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. For example, in a non-dissolvable tip embodiment of a tube assembly 94, a tip 96 includes a side vent 98. As best shown in Figure 9, the side vent 98 is defined by a central portion 100 of tip 96 and designed to discharge fluids into the patient (P). In the described alternate embodiment, a second vent 102 is positioned generally opposite the first vent 98 and a plug 104 is utilized to occlude both vents. Additional vents may be integrated into the tip 106 or the tube 106, however, to allow a higher flow rate of water, radiographic contrast media, nutritional formula, or other fluids as desired. Importantly, each vent creates a minimally restricted flow pathway for any fluids passing down the lumen of the tube 106. Hence, patients may receive nutritional formula as soon as the tube 106 has been placed into the gastrointestinal tract with no need to wait until a plug 104 has completely or partially dissolved.
[0086] As suggested above, the tube assembly 94 is supplied with the first and second vents 98, 102 occluded by a plug 104. As with other elements of the embodiments described herein, the plug 104 is press or friction fit into position within the central tip portion 100 resulting in the initial occlusion. While in this position, fluid traversing lengthwise within the tube 106 is diverted by the plug 104 through irrigation channels 108 in the tip 96. The irrigation channels 108 are substantially the same in form and function as the irrigation channels 62 described above in other embodiments.
[0087] As shown in Figure 10, the plug 104 defines a central aperture 110 through which a mounting 112 at least partially extends. The mounting 112 is substantially the same in form and function as the mounting 52 described above in other embodiments. Although the mounting 112 does not necessarily contact the plug 104, the mounting provides a further mechanism to maintain the plug in position within the tip 96 both prior to and during placement of the tube 106. Once positioned, the mounting 112, camera 114, and fiber optic filaments 116, 118 are withdrawn using an attached stylet (not shown) and the tube 106 is ready for fluid flow. [0088] In the described embodiment, the plug 104 is made of a dissolvable material. Specifically, the plug 104 is designed to remain intact to facilitate the insertion process and placement of the tube 106 and then dissolve away. This leaves the initially occluded first and second vents 98 and 102 in the tube 106 unobstructed allowing fluid flowing along the long axis of the tube to exit the tube. In order to dissolve away, the plug 104 comprises a material, or materials, which are soluble and suitable for human or animal consumption. One soluble material is a polymer marketed under the registered trademark Affinisol . Broadly speaking, any soluble material may be utilized.
[0089] As further shown in Figure 9, the plug 104 includes a first external surface 120 which substantially conforms to an exterior shape of central tip portion 100. In other words, the first external surface 120 substantially conforms to the first side vent 98. Similarly, a second external surface 122 of the plug 104 substantially conforms to an exterior shape of the central tip portion 100 or the second side vent 102.
[0090] In the described alternate embodiment, the tip 96 is permanently attached to a distal end of the tube 106. As shown in Figure 9, a connector 124 may be used to releasably connect the tip 96 to a fitting 126 on the tube 106. The fitting 126 may be any industry standard fitting. One suitable fitting is marketed under the registered trademark EnFit. In addition, the tip 96 may include a rounded distal portion 128 similar to that of tip 16. The rounded distal tip portion 128 may be similarly press fit into the central tip portion 100 or may be integrally formed/molded. In still other embodiments, the rounded distal tip portion 128 and/or the central tip portion 100 may be partially or entirely made of soluble material as described throughout.
[00 1] All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
