The present disclosure relates to systems, devices and methods for maintaining catheter patency, and more particularly, systems, devices and method for maintaining patency of indwelling vascular access catheters.
Indwelling catheters are used, either alone or in combination with implantable medical devices (such as, but not limited to, implantable access ports) to provide access to the vasculature of a host for delivery of materials (e.g., drugs) and/or for removal/replacement of materials (e.g., blood). Over time, in-growth and clotting may clog indwelling catheters, either reducing fluid flow or completely preventing fluid flow through the catheter.
One method of trying to maintain patency of the catheter includes flushing the catheter with saline or other fluid agents, but these approaches may have only limited success. Once in-growth has begun, the efficacy of flushing alone may become limited, and clogging may ensue. Moreover, material removed from the catheter by the flushing may deposited into the vasculature of the host, particularly elsewhere in the circulatory system.
Features and advantages of the claimed subject matter will be apparent from the following detailed description of some example embodiments consistent therewith, which description should be considered with reference to the accompanying drawings, wherein:
It may be appreciated that the present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The invention(s) herein may be capable of other embodiments and of being practiced or being carried out in various ways. Also, it may be appreciated that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting as such may be understood by one of skill in the art.
Throughout the present description, like reference numerals and letters indicate corresponding structure throughout the several views, and such corresponding structure need not be separately discussed. Furthermore, any particular feature(s) of a particular exemplary embodiment may be equally applied to any other exemplary embodiment(s) of this disclosure as suitable. In other words, features between the various exemplary embodiments described herein are interchangeable as suitable, and not exclusive.
By way of a general overview, the present disclosure may feature systems, devices, and/or methods for maintaining patency of an indwelling medical system. The systems, devices, and/or methods according to at least one embodiment of the present disclosure include a patency system having an elongated shaft and one or more cleaners configured to be at least partially disposed within the indwelling medical system. The cleaners are configured to dislodge debris (e.g. in-growth) forming within the indwelling medical system (e.g., a lumen of an indwelling catheter and/or a vascular access port), and may include one or more cleaners, such as one or more brushes, augers, jets, protrusions and strands. The patency system may optionally include one or more balloons, movable seals and/or valves configured to seal against a portion of the indwelling medical system, such as the indwelling catheter, to prevent dislodged debris from entering into the host's circulatory system or elsewhere in the indwelling catheter. The patency system may also optionally include one or more flushing sources and/or vacuum sources to facilitate the removal of dislodged debris from the indwelling medical system.
The patency system according to the present disclosure may be used to maintain the patency of an indwelling medical system. Referring now to
Optionally, the indwelling medical system 1 may include a second medical device, such as in the form of a vascular access port 5 coupled to a second end 6 of the indwelling vascular access catheter 2.
Examples of the indwelling medical systems, and tools for use therewith, may include, but are not limited to, those described in U.S. patent application Ser. No. 10/890,909, filed Jul. 13, 2004; U.S. patent application Ser. No. 11/234,497, filed Oct. 4, 2005; U.S. patent application Ser. No. 14/231,392, filed Mar. 31, 2014; U.S. Patent Application Ser. No. 61/974,807, filed Apr. 3, 2014; U.S. Pat. Nos. 5,906,596; 6,527,754; 7,803,143; 7,803,143; 7,811,266; and 8,377,034, all of which are incorporated herein by reference, to the extent they are consistent with the present disclosure.
While the indwelling medical system 1 illustrated in
For ease of explanation, the patency system will be described in combination with an indwelling medical system 1 having an indwelling catheter 2. As such, the patency system may be referred to as a catheter patency system and the indwelling medical system may be referred to as an indwelling catheter system. It should be appreciated, however, that the patency system according to the present disclosure may be used to maintain the patency of any indwelling medical system and/or medical device with or without a catheter.
As can be seen, in-growth, hereinafter referred to as debris 7, which may include clotting such as fibrin and coagulum, may form within a portion of the indwelling medical system 1 such as, but not limited to, lumen 8. More particularly, the debris 7 may form on the interior surface 9 of the lumen 8 anywhere along the length thereof (i.e. the vascular access port 5 and/or the indwelling catheter 2). The debris 7, if left untreated, may reduce and/or prevent fluid flow through the lumen 8 of the indwelling medical system 1, and may possibly break loose and enter the host's vasculature. The patency system disclosed herein may be used to remove at least a portion of the debris 7 at any location along the lumen 8 of the indwelling medical system 1, particularly the lumen 8 of either the vascular access port 5 and/or the indwelling catheter 2.

According to one embodiment, one or more portions of the elongated body 14 (e.g., the proximal section P, distal section D, and intermediate section I) may have different flexibilities, pushablities, and/or kink resistances. For example, the proximal section P may be more rigid compared to the intermediate section I, and the intermediate section I may be more rigid compared to the distal section D. The distal section D may be the most flexible. One or more of the sections P, I, D may include, for example, a spiral reinforcement and/or different materials to allow the flexibility, pushability, and kink resistance to be customized and/or selected along the length of the elongated body 14.
The distal section D may optionally include a distal end tip 21 configured to reduce and/or eliminate the potential of the tip 21 from becoming caught in and/or damaging the indwelling catheter system 1, particularly the lumen 8, as the catheter patency system 10 is advanced into and through the lumen 8 of the indwelling catheter system 1. For example, the tip 21 may include a resiliently deformable portion configured to deflect the tip 21 as the catheter patency system 10 is advanced through the lumen 8. According to one embodiment, the tip 21 may include a balloon and/or may have a rounded configuration.
The proximal section P of the elongated body 14 may include a handle 16. The handle 16 may facilitate the gripping of the elongated body 14 by a user (e.g., a surgeon, clinician) when advancing the elongated body 14 of the catheter patency system 10 into and/or out of the lumen 8 of the indwelling catheter system 1 and/or rotating the catheter patency system 10 about the longitudinal axis L. The handle 16 may include, but is not limited to, a T-handle, an area with increased friction (gripability). The handle 16 may also provide a stop member which contacts against the indwelling catheter system 1 to prevent the tip 21 of the catheter patency system 10 from extending into the vasculature (e.g. lumen 4 of the blood vessel). Alternatively (or in addition), the proximal section P may include a coupler portion 18,
As discussed herein, the catheter patency system 10 also includes at least one cleaner 12. While the cleaner 12 is illustrated as being located on at least a portion of the distal section D, it should be appreciated that this is for illustrative purposes only and that one or more of the cleaners 12 may be located along any portion (including the entire length) of the elongated body 14.
According to one embodiment, the cleaner 12 may include one or more cleaning members, such as brushes 24. The brushes 24 may be arranged in any configuration. The configuration may include one or more rows of cleaning elements, such as one or more rows of bristles 26, which may be arranged such that the bristles 26 extending longitudinally along a length of the distal section D. The one or more rows of bristles 26 may also be arranged in a circular (ring) configuration, a spiral configuration and/or a helical configuration. The bristles 26 may be configured to extend generally radially outwardly from the elongated body 14 as protrusions, and may be arranged to provide bumps and/or ridges. The bristles 26 may be formed of the same of different materials. For example, the bristles 26 may include different materials to adjust the stiffness and/or friction.
The bristles 26 may extend radially outwardly from the elongated body 14 (i.e., the radial length R) such that the bristles 26 generally engage and/or contact against a portion of the interior surface 9 (
According to one embodiment, the bristles 26 may be configured to be arranged in an expanded position (e.g., as generally illustrated in
As may be appreciated, the catheter patency system 10 may be more easily advanced within the lumen 8 of the indwelling catheter system 1 while in the collapsed position compared to the expanded position. Additionally, the catheter patency system 10, when in the collapsed position, is less likely to inadvertently dislodge debris 7 from the lumen 8 of the indwelling catheter system 1 while being advanced into the lumen 8 of the indwelling catheter system 1 (i.e., when the elongated body 14 of the catheter patency system 10 is advanced in the direction generally opposite to arrow A in
According to one embodiment, the bristles 26 may be configured to easily bend, collapse, fold, or otherwise move towards the elongated body 14 into the collapsed position as the catheter patency system 10 is advanced into the lumen 8 of the indwelling catheter system 1, and extend radially outwardly into the expanded position when the catheter patency system 10 is advanced out of the lumen 8 of the indwelling catheter system 1 (e.g., withdrawn from the indwelling catheter patency system 10 generally in the direction of arrow A in
According to another embodiment, the catheter patency system 10 may include a position selector 28 (

To remove debris 7, the catheter patency system 10 may be rotated as described herein. The rotation of the auger 30 causes debris 7 to be dislodged from the interior surface 9 of the indwelling catheter system 1. Additionally, rotation of the auger 30 causes dislodged debris 7 to be urged proximally (e.g., generally away from the distal section D and generally towards the proximal section P), thereby reducing and/or eliminating the potential for dislodged debris 7 to exit the indwelling catheter system 1 and enter into the host's circulatory system or be lodged elsewhere in the indwelling catheter system 1.
With reference to
According to yet another embodiment as shown in
It should be appreciated that the catheter patency system 10 is not limited to each individual type of cleaner 12 described herein. Additionally, the catheter patency system 10 may include a plurality of cleaners 12. For example, as shown in

In practice, elongated body 14 of the catheter patency system 10 may be advanced into the lumen 8 of the indwelling catheter system 1 while the balloon 40 is deflated (or at least partially deflated). To remove debris 7, the balloon 40 may be inflated via the inflation lumen 38 such that the balloon 40 contacts the interior surface 9 of the lumen 8 of the indwelling catheter system 1 as generally illustrated in
According to at least one embodiment, the balloon 40 may generally form a seal with the interior surface 9 of the lumen 8 to thereby preventing dislodged debris 7 from exiting the indwelling catheter system 1 and entering into the host's circulatory system. The catheter patency system 10 may be advanced generally in the direction of arrow A and/or rotated about is longitudinal axis L while within the lumen 8 of the indwelling catheter system 1 (e.g., using with the handle 16 (

In practice, the cannulated balloon shaft 42 (and optionally the balloon 40) may be at least partially received within the lumen 38 of the catheter patency system 10 may be advanced into the lumen 8 of the indwelling catheter system 1. The balloon 40 may optionally be deflated (or at least partially deflated). To remove debris 7, the balloon 40 may be inflated via a lumen 43 of the cannulated balloon shaft 42 such that the balloon 40 is advanced outwardly from the elongated body 14, for example, beyond the tip 21. The inflated balloon 40 may contact the interior surface 9 of the lumen 8 of the indwelling catheter system 1 such that the balloon 40 generally forms a seal with the interior surface 9, thereby preventing dislodged debris 7 from exiting the indwelling catheter system 1 and entering into the host's circulatory system. The elongated body 14 and the cleaner 12 of the catheter patency system 10 may be advanced generally in the direction of arrow A and/or rotated about is longitudinal axis L while within the indwelling catheter system 1 (e.g., using with the handle 16 (

Any of the catheter patency systems 10 described herein may be inserted into an external communication channel (e.g., but not limited to, a needle extending through the host's skin from an access port) and advanced within the indwelling catheter system 1. Alternatively (or in addition), any of the catheter patency systems 10 described herein may be inserted through the host's skin and into the indwelling catheter system 1 (e.g., an access port) using a needle.
Alternatively (or in addition), any of the catheter patency systems 10 described herein may be indwelling within the indwelling catheter system 1 until it is used (and optionally reused, removed, and/or replaced). For example, one embodiment of an indwelling catheter system 1 is generally illustrated in
A catheter patency system 10 consistent with the present disclosure may be disposed at least partially within the lumen 8 of the indwelling catheter system 1 and the patency port 69. The patency port 69 may be configured to allow a user (e.g., a surgeon, clinician, host) to gain access to the catheter patency system 10 such that the user can operate the catheter patency system 10 to dislodge debris 7 as described herein. For example, the patency port 69 may be coupled to a portion of the access port 66 and/or the lumen 8 (e.g., by way of a coupler or seal 75) such that the catheter patency system 10 may be disposed therein and the patency port 69 is generally sealed from the access port 66. The patency port 69 may also include a needle 76 configured to selectively extend and retract through the user's skin 70 such that the user can gain access to (e.g., grasp) the catheter patency system 10 and operate the catheter patency system 10 as described herein.
It should be appreciated that any of the features described herein may be combined. For example, any of the cleaners, lumens, balloons or elongated shafts in any of the embodiments described herein may be combined with any of the cleaners, lumens, balloons, elongated shafts in any other embodiments.
