5 is a cross-sectional view of a modified embodiment of the implanter of FIG.

6 is a partial cross-sectional view of yet another embodiment of an implanter according to the present invention having a supply mechanism for supplying a component to affect body fluids.

The present invention relates to an implanter and a method for introducing the same, which are to be located in a living body cavity. As is known, under certain circumstances it is desirable to mount the implanter in vivo in an animal body. Transplantation is particularly well known for cardiac disease, skeletal therapy, and dental care.

When implanted in a living body cavity with mucosal lining, it is difficult to firmly fix it there. Moreover, when the implanter is used for the purpose of influencing body fluids, there are problems related to the effect on body fluids and ancillary problems related to the distribution of body fluids.

Therefore, the main object of the present invention is to provide a novel implanter and its introduction and fixing method which solves the above problems and the like.

More specifically, it is an object of the present invention to provide a transplantation method and implanter without any difficulty associated with the presence of a mucosa located within the body cavity where the implanter will be installed.

It is another object of the present invention to provide a structure that realizes an extremely firm and stable fixation of the implanter in a desired place. Another object of the present invention is to provide an implanter having a mechanism capable of effectively affecting the state of body fluids.

According to the present invention, the mucous membrane in the body cavity receiving the implant is removed at least as much as the portion occupied by the implant. Moreover, when the implanter is in place, the barb of the implanter penetrates into the tissue, enabling a firm settlement of the implanter. The ingrown growth zone of the tissue is self-grabbing between the inner wall of the body cavity from which the mucous membrane has been removed and the implantation device, which promotes the inward growth of the tissue, thereby more firmly anchoring the implant, and thus between the implant and the inner wall of the body cavity. Leakage-free flow coupling of body fluids The implanter takes the form of a valve that allows fluid to circulate when placed in the body cavity, thereby adjusting the flow of body fluid. Furthermore, such valves can be associated with components to be injected into the body fluids to affect the body fluids. In this case, the valve may also be provided with a mechanism that can arbitrarily choose to terminate or sustain the influence of such components.

In addition, according to the present invention, the mucosal removal port for introducing the implant into the position to install the implant, and the inward growth promoting tool for tissues, for example, the form of the wire wound around the implanter or the porosity placed on the implant ( An implanter provided with a multi-layered deposition plate can be provided. It is also possible to provide barbs to such implants that can be inserted into the tissues of the body cavity to secure the bonds of the implants. For example, when the implanter is a valve, it can be located in the male vas deferens, for example, to regulate the circulation of semen that carries sperm. When the implanter takes the form of a valve, it can also be associated with a mechanism that supplies a component that affects the bodily fluid flowing through it, in which case one of the valves can be given such an influence or the other can be interrupted. It is made of structure.

Although the present invention has been described in detail the specific embodiment applied to the vas deferens, the method and the implanter of the present invention is not limited to this, remove the mucosal lining anywhere throughout the body, and the effect on the body fluid is desired, body cavity It can be applied where it is desirable to fix the implant.

For example, the implanter of the present invention is used to supply hormones to body fluids flowing through the organs, and according to the method of the present invention, it can be located in the arteries through which blood is distributed, thereby coagulating blood. It can also be used as a means for supplying a component such as an anticoagulant for preventing blood to the blood.

As another use of the implanter according to the present invention, for example, a component which prevents a heart attack or a component which is used in connection with the regulation of thyroid function of a living body is introduced into the blood.

As described above, it will be apparent that the implanter and the method for introducing the same according to the present invention have various and wide uses for the whole organism.

Hereinafter, the present invention will be described in detail with reference to the embodiment applied to the male vas deferens as an example.

FIG. 1 is a schematic cross-sectional view in which the implanter 12 according to the present invention is applied to the vas deferens 10, whereby the implanter 12 takes the form of a valve, in which a rotary valve element is located, The ruler rotates between both positions of the grid and interruption by a portion (not shown) coupled to the elongate element that is rotatable within the vertically extending pivotal extension of the central portion 14. This central portion 14 is connected to tubular portions 16 and 18 which are in a spherical hollow housing and form an inlet and an outlet for the valve 12.

The canon tube 10 has a hollow tube steel (or lumen) 20 having the mucosa 22 as an inner wall. The elongated tubular portions 16 and 18 of the valve terminate at the smooth and curved end portions 24 and 26, which are shown to prevent the open ends of the tubular portions 16 and 18 from becoming obstructed. As the slot is formed. In the example shown here, prior to the introduction of the implanter of the implanter, an incision 28 as shown is formed by a procedure of surgery suitable for the vas deferens, whereby the implanter is joined with the lumen 22.

As one of the features of the implanter according to the present invention, the coronal sections 16 and 18 have inward circumferences 30 and 32 of the tissue on their outer periphery, in the example shown for the formation of porous deposited plates. It is supposed to be.

For example, when gold is sprayed on the outer circumferential surfaces of the tubular portions 16 and 18 as a suitable spraying air to form an adhesive phase, that is, in this case the tissue inward growth spheres 30 and 32, Due to the high porosity of the phase, the vas deferens grow inward and easily intercalate into the holes of the inwardly growing means 30 and 32.

As another feature of the implanter according to the present invention, the tubular portions 16 and 18 are provided with the mucosa removal holes 34 and 36 in a fixed state.

The mechanisms 34 and 36 take the form of an annular element fixed to the outer circumferential surfaces of the tubular portions 16 and 18, respectively, and have a pointed portion in the direction of the outer axis, and the outer shaft freedom of this portion. The edge is located at the end of the pointed portion of the mucosa 34 and 36 as shown. Due to the presence of such instruments 34 and 36, the external free axis of the instruments 34 and 36 is introduced into the lumen 20 when the implanter 12 is introduced. At the same time, the mucosa layer 22 is automatically removed to have a state as shown in FIG.

Therefore, when the implanter 12 is introduced into the vas deferens 10, the mucosal layer is removed from the medial side of the vas deferent ingrowths 30 and 32, resulting in the ingrowth of the vasculature of the vas deferens 10 There is no mucosa layer 22 between the 30 and 32 and the vas deferral inner axial surfaces. This removal of the mucosal layer allows tissue to rapidly grow into the inlets of the inward growth spheres 30 and 32, resulting in a firm fixation of the implanter and the outside of the coronal sections 16 and 18. Body fluid binding to the side is achieved. In other words, the implanter is not only firmly positioned due to the above-described characteristics, but also contrary to the purpose of leaking semen transporting sperm by the liquid flow coupling to the outside of the valve. This will not be possible.

Therefore, when the valve is closed, the semen is impossible to flow under the valve along the inside of the vas deferens, and as a result, pregnancy is firmly prevented. However, if you want to restore your fertility again, just open the valve, body fluids flow freely through the valve, the sperm is transported to normal. As such, arbitrary control of pregnancy and birth control is implemented.

In the method of introducing the implanter as shown in FIG. 1, the surgeon cuts only a portion along the vas deferens, leaving a continuous conduit 38 for accommodating the implant. This has the advantage that the conduits that will accommodate the tubular portions 16 and 18 remain permanently connected to each other as a continuous conduit portion 38 without breaking the nerves extending through the conduit 38.

However, as shown in FIG. 2, the surgeon may break the vas deferens completely and separate them into two parts 10a and 10b. Also in this case, the implanter 12 is introduced in the same manner as described with respect to FIG. 1, but the pair of mucosa removal ports 40 and 42 are mucosa removal holes 34 and 36 in the case of FIG. It is almost equal to, but its outer free edge is formed in anomalous serrated shape and its tip is made of relatively sharp barbs 44 and 46, which are separated from each other in the conduit 10a and 10b, respectively. Easily invaded. The barbs 44 and 46 having such a configuration make it possible to firmly fix the introduced implanter, particularly in the case where the organs receiving the implanter are separated from each other like the second column. In addition, even in the case of FIG. 2, regardless of having the barbs 44 and 46, the outer free edge portions 40 and 42 effectively remove the mucosal inner layer 22 as mentioned in the case of FIG. To achieve.

3 and 4 show an embodiment similar to the embodiment of FIG. 1. The vas deferens 10 are restored to the covering tissue 44 ', and the implanter 46' is introduced through the long incision 42. The implanter 46 ′ of the example shown here is substantially the same as the implanter 12 described above, except that the elongated tubular portion 50 and 54 are different lengths from each other as shown, and the coronal portion 54. As shown in the figure, a plurality of nodes concavely sleepy are provided. The elongated valve section 58 extends from the cylindrical diameter portion 40 of the valve housing in which the central portion is spherical. The rotary valve element 52 is accommodated in the valve housing, and the rotary valve element 52 is disposed in the valve housing 52. The through hole 54 is formed. The same structure is, of course, also applied to the valve of FIG. 1 and FIG. The outside 48 of the valve section 58 is formed with a through hole 60 into which the handle 62 is inserted, as shown in FIGS. 3 and 4. The handle 62 can be lowered to the position indicated by the pros and cons of FIG. 4 when not in use. The through hole 54 is positioned across the axes of the tubular portions 50 and 54 in the blocked state as shown in FIG. 3, and the tubular portion and the axial direction are positioned in the opened state of the valve. Thus, by allowing the valve to be in the fully open state or the fully blocked state, it is possible to control the flow of semen that transports the sperm.

In this case, as the inward growth promoting mechanism of the tissue, for example, the fine wire of gold is wound around the tubular portions 50 and 54, and the windings 66 and 68 wound on the outer surface of the valve neck 40. ). Such windings of microwires create gaps of very little distance between the windings, and the inward growth of the tissues between the gaps is promoted. Thus, the implanters 46 ′ of FIGS. 3 and 4 also have the same advantages as the implanters of FIGS. 1 and 2. On the other hand, the valve element in the implanter of FIGS. 1 and 2 also has an internal configuration of a valve internal element having a through hole as described with reference to FIGS. 3 and 4.

In the embodiment shown in FIG. 5, the porous layer 70 is the same as the examples shown in FIGS. 3 and 4, except for the inward growth means made of the fine wire windings in the cases of FIGS. 3 and 4. It is apparent that the porous layer 70 has the same characteristics as the tissue inward growth spheres 30 and 32 in the example of FIG.

Materials used for this shall be substances which do not affect the body, ie gold or platinum. And the size of the composition should of course be small enough to be suitable for introduction into the body cavity.

6 shows another embodiment of the present invention, wherein the implanter is configured in the form of a valve having a tubular inlet and outlet 86 and 86 as schematically depicted, the cylindrical neck having a valve housing within the valve housing. The stand fixed to the rotary valve body 84 accommodated in the housing | casing is accommodated. In this case, however, the rotary valve body 84 not only has a through hole 82 but also has a V-shaped through hole 80 on a surface perpendicular to the axis of the through hole 82 as shown in the drawing. The inside of the V-shaped through hole 80 is connected to the reservoir 88 through the wick 92 as shown in the drawing, and a liquid suitable for the reservoir 88, for example, spermizing material in this case. The same thing as i) is accommodated in aqueous solution form, and this wick 92 supplies it to the V-shaped ball 80 by aspiration action. As illustrated in FIG. 6, the V-shaped ball 80 is in communication with the inside of the tubular portion 86, and the sperm 80 is incorporated into the semen through the wick 92 so that the sperm 80 is the tubular portion 63. ) Is prevented, and instead connected to the through hole 82, the flow of semen is not disturbed. Thus, according to the mechanism structure shown in FIG. 6, one state flows unaffected at any state without inhibiting the flow of body fluid in any state of the valve, and in another state, the influence of the chemical agent 90 Can be given.

Of course, the configuration as shown in FIG. 6 can be introduced into the implanter of FIG. 2, and the barbs and the like can be combined with the embodiments shown in FIGS. 3 to 6 in addition to the mucosa shown in FIG. It is obvious that it can be formed.

As described above, the implanter according to the present invention is described. As a specific embodiment, the implanter is introduced into and used in the vas deferens, and related to the control of pregnancy function. In order to achieve this, it is possible to apply the implant anywhere by removing the inner layer of the mucosa, and it will be appreciated that the principles of the present invention apply to any case of introducing the implant into the body cavity.

Moreover, the barbs as shown in FIG. 2 are highly effective for the firmness of the implantation, and in particular, when the body cavity is divided into two parts, a good effect is obtained.

In addition, the apparatus described in FIG. 6 is particularly effective in achieving the purpose of adding an influence component to the body fluid when it is desired to affect the body fluid.
