Brief introduction to the Figures
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figures 1-5 each show a medical device according to an example embodiment of the present invention; Figure 6 shows a sectional view of a medical device according to an example embodiment of the present invention in place in a user of the device; Figure 7 shows stages in a method of use of a medical device, according to an example embodiment of the present invention; and Figure 8 shows further stages in a method of use of a medical device, according to an example embodiment of the present invention.
Description of Example Embodiments
Referring now to Figure 1 there is shown a medical device 1 useful in the treatment of anal fissure. The device 1 comprises a conduit that runs between a first end 11 and a second end 12. In use, the conduit extends from the first end 11 which remains external to the body, through the anus. The second end 12 lies internal to the body. The conduit maintains a passageway there-through between first and second ends 11, 12. The passageway supports the anus, and prevents damage thereto by stretching on passage of faecal matter. Faecal matter is isolated from the walls of the anus to aid healing, as the second end 12 of the conduit engages the body by flexing outward and over to press against an internal surface the body in the anal canal or rectum. By flexing outward and over the second end 12 of the conduit can be made of a relatively soft elastic material so as not to damage tissues inside the body, while still forming an effective seal against the inside of the anal canal or rectum to inhibit passage of faecal matter down the outside of the conduit to the area of anal fissure.
The conduit maintains the anus open, with the device 1 arranged to stay in place until healing of the anal fissure has taken place. During this time the user of the device 1 will produce faecal matter, which can pass from the second end 12 of the conduit to the first end 11 of the conduit through the passageway. The passageway has an internal wall surface 13 over which faecal matter passes as it moves from the second end of the conduit 12 to the first end of the conduit 11. On the outside of the passageway is an external wall surface 14 which is the surface that engages the anus.
As the second end 12 of the conduit flexes outward and over, it is the an extension of the internal wall surface 13 of the passageway that curls over itself to press against an internal surface the body, at a ring-like contact region 15 shown in Figure 1. The second end of the conduit 12 curls over itself for example two times to press against an internal surface of the body. In curling over itself the second end of the conduit 12 ensures that the edge of the conduit where the internal and external wall surfaces 13, 14 meet does not produce a high pressing force on the body at its extremity. The edge is protected within the curled-over portion of the second end 12. There is circular symmetry of the conduit to match that of normal anatomy, but different side sectional profiles such as that shown in the embodiment of Figure 4, with a generally flattened upper end are envisaged.
As will be appreciated from the Figures, the conduit is relatively wider at the second end 12 than at the first end 11 so as to funnel faecal matter from the second end 12 to the first end 11. To aid the outward flexion the conduit can be formed to be relatively more flexible at the second end 12 than at the first end 11, either by material variation or variation in dimensions.
For example, the curl can be fabricated in to the second end 12. A gradation in the properties of the second end can conveniently comprise a continuous tapering gradation, the gradation extending from the second end 12 toward the portion of the conduit arranged in use to sit against the anal sphincter. In the embodiment of Figure 1, the line 16 indicates the end of the gradation in properties of the second end 12. Below the line 16 the conduit is relatively more rigid than the second end 12 is, to enable the part of the conduit which contacts the anus to resist collapse. A silicone rubber material may suitably be used for the conduit, with reinforcement structures provided, either of the same material or for example encased in the material to give the required mechanical strength.
The first end of the conduit 11 is provided with a sealing arrangement in the form of a cap 17. The cap 17 remains accessible outside the body when the conduit is positioned in use. The cap 17 is releasably attached to the first end of the conduit 11 and is used to prevent leakage of faecal matter from the conduit. When the user of the device 1 feels the urge to pass faecal matter the cap 17 can be removed to allow this to happen, and then replaced on the first end 11.
To hold the device in place securely, retaining means are provided. In the accompanying Figures the retaining means comprise straps 18. The straps 18 are arranged to be tied around the body of a user U of the device 1, as shown in Figure 8. Straps are suitably provided on both cap 17 and at the first end 11 of the conduit. In other embodiment the straps that are directly coupled to the device may be secured indirectly to the body of a user for example using a suitable garment, belt or other fixing arrangement worn on the body. In other embodiments, for example the devices 3, 5 and 6 of Figures 3, 5 and 6 respectively, the first end 11 of the conduit may be shaped to sit in the cleft in the buttocks to aid positioning and for comfort.
Figures 2 and 3 show devices 2, 3 according to further example embodiment, in which the conduit comprises secondary passageways 20. The secondary passageways 20 are arranged to allow communication between the second end 12 of the conduit and the first end of the conduit 11. The secondary passageways 20 are isolated from the passageway along their lengths, and in the example embodiments shown are located between the internal wall surface 13 and the external wall surface 14 of the passageway. The secondary passageways open out at the internal wall surface 13 at the second end of the conduit 12 at second openings 22 of the secondary passageways 20, and open out of the external wall surface 14 at the first end 11 of the conduit at first openings 21. As shown in Figure 3, a secondary passageway 21 is branched, with two second openings 22 coupled to a single first opening 21.
The first opening 21 comprises a suction attachment portion for coupling to a suction device, which in use may assist in removal of mucus, faecal matter or other material from within the body without disturbing the anus. Example embodiments comprising secondary passageways may comprise a second end 12 of the conduit which is arranged to press against the body other than by flexing over on itself.
Figure 1 shows a portion of the external wall 14 of the passageway that comprises a medication delivery portion 19 arranged in use to deliver medication to the anus. In use the medication delivery portion is arranged to rest against the anus, and typically contains a substrate from which medication can be delivered to the anal tissue. Example medications or combination may include antibiotics, analgesics, anaesthetics, and muscle relaxants.
Figures 7 and 8 illustrate a method of inserting the device 1, using an applicator 7. The device is supplied within the applicator 7, as shown in configuration of the left-most drawing of Figure 7. A plunger 8 is used to push the device 1 out of the applicator 7. As the device I exist the applicator 7 it progressively expands outwards by flexing, and curls at the second end 12 of the conduit. This process is illustrated in the configurations moving from left to right in Figure 7. The operations of Figure 7 by which the device 1 exits the applicator 7 are performed with the applicator 7 partially inserted into the body of a user. Figure 8 shows the insertion of a suitably lubricated applicator 7 in the upper left image, and the removal of the applicator 7 to leave the device 1 in place in the upper right image. The lowermost image of Figure 8 shows a front view of the straps 18 securing the device 1 in place.
The embodiments and methods described herein are relatively simple to construct and easy to use. By supporting the anus and reducing contamination and straining healing of anal fissures is facilitated. The device is easy to insert, and is arranged not to damage the internal surface tissues of the body. The device deals with passage of faecal matter and can be secured in place to avoid unwanted expulsion. By enabling suction to be applied through the device's secondary passageway additional flexibility in treatment is enabled, above any beyond the medication delivery that is made possible directly to the affected areas.
