The thing is, the introduction of the catheter into the body from the groin artery with roots thigh and 'monitor, folding the distal portion only positioned as near the affected area that elicit an aneurysm or the like, within the catheter Z insert in the folded state a given with a cylindrical artificial blood vessel with a recoverable elastic, while feeding transportable to a predetermined position near the affected area using lotus transportable device and the traction device, to release from the catheter at that position by the this, and an artificial blood vessel can be positioned in the blood vessel portion component that caused the aneurysm or the like. However, in such documents, in order to transport the artificial blood vessel, a relatively small diameter tube which Koirusupuri ring is continuously provided on the deformability. A tip, a side window portion provided in the vicinity of the front end portion of the tube are used a pair of strap loops is formed on the intermediate fixed both end portions in the vicinity of the side window, the carrier device comprising a wire. Tokyo and is moved freely 揷入 into the tube. However, in conveying apparatus having such a configuration, because the tube is operated part is the ratio ^ target diameter, hand source operating force may not easily and have it inconvenient transmitted to the distal end of Ju some further , the tube is said to have a deformability, because of a relatively small diameter, there is also a risk want broken songs on the way.

To solve the above problems, it is conceivable thick to Rukoto the diameter of the tube, Then since a state tube which is 揷通 in artificial blood vessel being folded, folded artificial blood vessel is bulky inevitably produce a new disadvantage that put away.

On the other hand, the conventional conveyor, although elastic has to be bent by an external force, what is configured forms a linear shape unless an external force so as to bend freely in the free direction is customary . Therefore, as or curved affected part is the object point, the introduction path in the middle is curved affected part when such forms straight can be adapted simultaneously to the shape of the shape and the affected area of ​​the path various characteristics are not provided, the introduction of the course is may become a thing of the resistance big, transplant conditions have also had a problem that tends to be inadequate. Disclosure of the Invention

In order to solve the above problems, the present invention is conveyor der connexion of transplantation device comprising comprising a separable operating rod against integrally transportable and transplantation device with transplantation fixtures , and Toku徵 by further comprising an auxiliary operating rod, which can transmit directly the operation force applied to the exterior of 'Re proximal side to said control rod to the distal end of the operating rod.

The capturing specific embodiment of the auxiliary operating rod, said a pipe member disposed at a position exterior to near the tip portion of the operating rod, the operating force is built in this pipe member applied to the base end pipe which is composed of a tube for transmitting near the tip end of the operating rod through a member thereof.

More specifically, like the pipe member, and the large-diameter tip, is made to constitute a base end portion fine-diameter base end portion which is made by consecutively provided housed in said tube of its It is.

Further, the lock mechanism, constructed from a base end portion of the pipe member and the locking element among selectively locking the operating rod, an outer locking element selectively locking and the tube proximal end portion of the pipe member what you are is valid.

In order to effectively achieve both the flexible bending state of the auxiliary operating rod in reinforcing the body against the operating rod is intended pipes member is made of metal, it is desirable that the tube is made of resin.

The operating rod comprises a tubular element forming the two shed-to each other, a tube connecting element for connecting the these two tubular element while forming an opening between the two tube elements, Wataru between both tube elements ; and a connexion 揷通 capable wire, thereby immerses again tip the wire after engaging the transplantation device at its distal end is exposed from the opening moved relative to the tubular element into the opening Accordingly, if one intends to tethered be conveyed integrally between the transplantation device of the wire and the tube element, previously formed a cup-shaped space which opens toward the forward tip portion of the auxiliary operating rod it is advantageous that fitted the 'tip connecting portion between the tube element and the tube coupling element proximally. Further, when the operating rod is of the above structure, the connecting portion between the tube element and the tube connecting element proximal, previously formed a cup-shaped space open mouth toward the rear, the coupling may also be inserted into the distal end portion of the auxiliary operating rod in portion, further, the distal end portion of the auxiliary operating rod, to substantially the same diameter as the rear end portion of the connecting portion between the tubular element and the tube connecting element proximal and advance, with respect to the rear end of its, the tip portion of the auxiliary operating rod close to or may abut. As a preferred embodiment of the conveying device to be applied to the case where the affected part is curved, be comprised comprises a separable operating rod against integrally transportable and portability instrument with transplantation device, the configure operating rod and an auxiliary operating lever of a material having a bendable elasticity, and the least also one of the distal end of these operations 杆又 the catching aid Misao Saku杆, and those forming a predetermined shape with no external forces Te, there may be mentioned those tip side auxiliary operating lever on the outside of the operating rod is configured by covering so as to be out.

Desirable embodiments of the operating rod and an auxiliary operating rod, a curved shape in a state where the top end of the operating rod is not applying an external force, and that to name a substantially linear shape in a state in which the leading end side of the Tosuke operating lever is not applying an external force, the operation each distal end of the rod and the auxiliary operating lever is, it may include those that form a curved shape in a state where both not apply external force.

In this case, transplantation device is, which forms a bend in shape when reconstituted in a predetermined position, it is desirable that the intended curved shape match Ryakugo the operating rod to its curved shape.

Further, as a preferred embodiment, transplantation device is, which is transported by the folding or condition is provided an elastic member in site located Xiaowan side when restoring encourage contraction of the instrument body mention may be made of things.

Furthermore, transplantation device may be one provided with a branch to a site you positioned greater curvature side when restoring.

'As preferred form of the operating rod and an auxiliary operating rod, a substantially linear shape in a state where the top end of the operating rod is not applying an external force, the distal end side of the auxiliary operating rod external force' what to name a curved shape with no added it can be mentioned.

More transporter becomes extremely useful when applied to the artificial blood vessel is one particularly transplantation device.

If it is carrying device transplantation device according to the present invention, since it comprises an auxiliary operating lever for assisting the operating rod, the operating rod is be one but because fragile is a flow Rekishiburu, transported to the target position because until it is the this conveying operation force through the auxiliary operating rod without relying on the strength of the operating 杆自 body directly to the distal end of the operating rod, the operating rod is effectively prevented want earthenware pots inconvenience bent halfway transportation can.

The coupling state of if separable for the transportable and operating rod integrally with the operating rod of the auxiliary steering Saku杆 via a locking mechanism provided on the base end side, an auxiliary operating rod and the operating rod the can you are sure, auxiliary operation 扦 will release the connection at any time through the operation at the base end side when no longer needed, the auxiliary operating rod can be retracted.

On the other hand, the auxiliary operating rod, a pipe member disposed at a position exterior of the distal end portion of the operating rod, the operating rod through a pipe member operating force applied to the proximal end side by continuously provided in the pipe member if constructed from a tube for transmitting the tip portion, Ki out to transmit the operating force while reinforcing the front end portion near the operating rod by sheathing the pipe member, also separately tube to the pipe member for transmitting the construction and operation force to the pipe member, as compared with the case of pulling out the pipe member having the strength to remain the base end side of that, employing a flexible pipe member with a flexible part in the middle of the operation force transmission it is possible to perform routing in the body suitably with.

In that case, the pipe member, and the large-diameter tip and keep the ones formed by composed of a small diameter of a base end portion which is housed in it by building the tube at its proximal end, a simple composed, if possible on which can effectively prevent the bending and the reinforcement near the tip of the operating rod to more reliable, the pipe member within the body, hence, the flexible bending state of the auxiliary operating rod Close.

The configuration of the locking mechanism, the base end portion of the pipe member and the locking element inner selectively locking the operating rod, an outer locking element which selectively mouth click a and the tube proximal end portion of the pipe member them if the auxiliary 'pipe member constituting the operation punch can be Rukoto a connection to the operating rod of the switch Yubu both the more reliable, also by operating the two locking elements, saving them as necessary also can be easily intends butterfly.

Further, a pipe member to one made of metal, if the tube made of tree butter, can maintain the strength of the connecting portion between the operating rod and Tosuke operating rod, further, the base end side of the auxiliary operating rod while ensuring flexible bending characteristics operation force applied to it it is possible to transmit up to the tip of more suitably operating rod.

Et al is, when the operating rod is connected between the two tubes elements tube coupling element, you are to engage the selective transplantation device with their wires are 揷通 therein, One suited forward tip portion of the auxiliary operating rod in advance to form a cup-like space you open, if fitted to the distal end portion to the connecting portion between the tubular element and the tube connecting element proximal, the base end side near the connecting portion between those proximal end side of the tubular element and the tube coupling element bends can be effectively prevented. If the operating lever is Ru der having a structure described above, previously formed a cup-shaped space which is open towards the rear in the connection portion between the tubular element and the tube connecting element proximal, auxiliary operation in this connection portion even those were 揷入 the tip of the rod, also, the tip portion of the auxiliary operating rod, the rear end portion. Tohopo same diameter of the connecting portion between the tubular element and the tube connecting element proximal and advance, with respect to its rear end, even those that the tip portion of the auxiliary steering Saku杆 in contact proximity or equivalent, the same effects as described above.

Further, transportation devices transplantation device is composed of a material having a bendable and operating rod and Tosuke operating rod elasticity, a and these operations 杆又 less and also one of the front end side of the auxiliary operating rod ', the external force and those forming a predetermined shape with no added, as long as the distal end side auxiliary operating lever on the outside of the operating rod is constructed over the earthenware pots by the possible out, assisting the distal end side of the operating rod Misao rod in the state that houses the tip side, the operating rod is being corrected into a shape having the auxiliary operating rod capturing, when the distal end side of the auxiliary operating rod capturing the tip side of the operating rod is protruded forward is , the operating rod is released to be bound by co operating rod capturing regains a predetermined shape to be given inherent. Therefore, the operating rod, while the shape suitable for fixing to the target site of transplantation device, in such a case the shape of the operation "is not suitable for routing the introduction path in the body, capturing aid operation rod by temporarily accommodate the operating rod inside the auxiliary operating rod a shape suitable for passage of the introduction path and the delivery of the operating rod in the introduction path to the target site of that in appropriate can do.

It distal end side of the operating rod is name a curved shape with no external force is applied, the distal end side of the auxiliary operating lever is as long as a substantially linear shape when no external force is applied, to accommodate the operating rod inside the auxiliary operating rod in it are state, the operating rod is to hold the substantially linear shape unless applied is to an external force correction to the auxiliary operating rod, it is easy to feed operation, further, the introduction passage is prevented that the bending characteristics is biased to a specific direction whereas it can respond suitably be curved to various directions indefinitely, when feeding the operating rod to the outside of the auxiliary operating rod, the regain curved operating rod is that is given originally. Therefore, the curve degree, if in correspondence to the degree of curvature of the affected area in order to previously arranged, Te cowpea to be advanced only this operating rod from the front of the affected, fed suitably a transplantation device to the affected area be able to. Operating rod a substantially linear shape in a state where the top side is not applying an external force, the front end side of the auxiliary operating lever is as long as it forms a curved shape in the absence of an external force, to accommodate the operating rod inside the auxiliary operating rod in a state where there, the operating rod is to retain a curved shape unless applied is to an external force correction to the auxiliary operating rod, it is matched the curved shape to the curvature when the introduction path to the patient part is curved if it, whereas it is possible to preferably perform the introduction, when the sending out of the co-operating rod catching the operating rod, the operating rod regain the original given by. are substantially linear shape. Therefore, the curved front of the affected part, the affected area itself if such forms a linear shape, by advancing only steering Saku杆 from the front of the affected part, can be suitably feeding the transplantation device to the affected area .

Each distal end of the operating rod and an auxiliary operating lever are both in a state in which no external force is applied, as long as it forms a curved shape, the curved introduction path to the affected area, although the affected area itself is curved again, the curvature of the affected area the degree and the direction of curvature introduction passage-Re applied to the case such that different and useful.

Transplantation device is, which to name a curved shape upon reconstitution with a predetermined position, if in the one operating rod to its curved shape of the curved shape that substantially matches the curved shape of the operating rod, transplantation device a curved shape, by leaving substantially to conform to the curved shape of the affected part to be'll both advance transplantation, after sending the affected area before or al operating rod, causing interference fixing or in the transplantation device into the affected mutually It can Rukoto to perform extremely smoothly without.

Moreover, if the projections 2 0 b Z l of the luer lock part 20 b Z and is disengaged from the spiral groove 2 0 b X l free the tubing 2 2, the tube while leaving the pipe member 2 1 at that position advancing the 2 2 only 'is possible.

On the other hand, the traction device 1 4, as shown in FIG. 9, the point number of the cord 2 9 are two in correspondence to the number of hook portions 9 after the artificial blood vessels 1, component auxiliary operating rod except that no a, Ru der those having the same structure as the conveying device 1 3.

Specifically, those containing the wire 2 7 into the tube 2 6, the auxiliary end wire ring 7 after the rear end side to the wire 2 7 slide out once from the opening 2 8 provided in the tube 2 6 part are previously attached by engaging the hook portions 9 after that has been provided, by pulling back the tube 2 6, the rear auxiliary end wire ring 7 and engage and hold the front Symbol carrying an artificial blood vessel 1 the device 1 3 is capable of pulling in the opposite direction.

Next, a description provides procedures for folding the artificial blood vessel 1 of the above-described configuration.

First, by locking the locking mechanism 2 0, the operating rod '1 8 and auxiliary operating lever 1 9, i.e., the operation lever 1 8 and the pipe member 2 1 of the proximal end portion 2 1 B, the base end portion 2 1 B and a tube 2 2 in a state which enables the transport one body to, insert the conveying device 1 3 in the artificial blood vessel 1, .4 pieces of cord 2 4 each split point of the artificial blood vessel 1 6 a, 6 b, 6 c, 6 d and dividing point 6 b, 6 c, 6 d, passed through a hook 8 before forming a loop which is provided in advance attached to four locations of the intermediate position 6 a, in Figure 6 as shown, Ru successively hooked loop 2 4 a of the cord 2 4 to the distal end 2 5 a of the wire 2 5 exposed from the opening 2 3 of carrier device 1 3. Thereafter, by the pushing wire 2 5 of the tip 2 5 a again operating rod 1 8 distal end side of the tubular element 1 in 8 A of connexion, the artificial blood vessel 1, as shown in FIG. 7, the transport instrumentation coffer 1 3 via the front hook 8 and strap 2 4 fitted state is anchored to the carrier device 1 3. At this time, the tip 2 2 a of the tube 2 2 is positioned on the base end side than the rear end of the artificial blood vessel 1, as shown in Figure 6. This is because when the artificial blood vessel 1 is 揷通 the tube 2 2 in its inner space, bulky when folded, it is not possible to achieve a more compact folded state. Therefore, when the less compact is in the folded state is not required, the tube 2 2 its tip 2 2 a may be previously advanced to a position where it comes into contact with the large-diameter portion 2 1 A of the pipe member 2 1. If so this, coupled with the large diameter portion 2 1 A and tube 2 2 becomes stronger.

Next, as shown in FIG. 9, the conveying device 1 3 similarly to 牽 drawing device 1 4 was inserted into the artificial blood vessel 1, two straps 2 9 each portion hooked after artificial blood vessel 1 in that state 9 through to. mooring and towing device 1 4 and artificial blood vessel 1.

Thus, as shown in the first 0 Figure ~ first 2 figure, 揷入 with funnel-shaped tube 3 0 and Pinse Tsu DOO 3 3 artificial blood tube 1 to cartridges 3 1. Although the figure is inserted an artificial blood vessel 1 to the cartridge 3 in 1 using tweezers 3 3, user without a tweezers to 揷入 folding the artificial blood vessel 1 give the proper shape by hand it is also possible. Hereinafter, specifically how to 揷入 using tweezers 3 3.

First, as shown in the first 0 Figure, two points opposite (e.g. 6 a, 6 c) is forwardly across the out axis of the split point 6 a vascular prosthesis 1, 6 b, 6 c, 6 d headed so that the top of the chevron, i.e., while Ategai the tweezers 3 3 along a base line passing through these division points 6 a, 6 c, 揷 the distal end side of the artificial blood vessel 1 to the funnel-shaped tube 3 0 you type. It as locations picked by tweezers 3 3, i.e., cartridges 3 1 while dividing point 6 a, 6 c before capturing co-ring end wire 6 of the artificial blood vessel 1 is flatly collapsed as brute close together whereas encapsulated into priority basis within, split point 6 b, 6 d except it is restricted the driven and 攛接 the inner periphery of the tapered surface of the funnel-shaped tube 3 0. Therefore, the division point 6 a forward, 6 c becomes the top of the mountain when the front auxiliary-ring end wire 6 is led to the vicinity of one end 3 1 a of the cartridges 3 1, other [delta]. Split point 6 b, 6 d becomes the bottom of the valley-shaped, before capturing auxiliary end wire ring 6 is Ru bent regular wavy as a whole. Furthermore, other-rings end wire 2, 5, 5 A, 6, 7 is also bent into a wave shape in the same phase. At this time, the division point 6 a, 6 b, 6 c, 6 d and dividing point 6 b, 6 c, 6 d, 6 ^ hooking portion 8 before four locations formed in the middle of the 0, Yamagata tinge toward the front It will be positioned on top of the. At this time, the pull one over. Parts 8 is not shown in the first 0 Figure, as shown in the first FIG. 1 and the first 2 figures, mooring the transport equipment 1 3 via the cord 2 4 located in the state. At this time, through the front hook portion 8 of the artificial blood vessel '1 by introducing different, lace from cartridges 3 1 side as required, the by connexion artificial blood vessel 1 to the pulling this string cartridge 3 1 it is also effective to draw the.

Next, lotus transportable to an artificial blood vessel 1 is folded as described above within the eye position, that is, the affected area 3 4. First, as shown in the first 4 figures, the body through femoral artery of the base F of the foot, as well as introducing the catheter 1 2 comprising a sealing mechanism 1 2 a proximally aneurysm its tip position, such as in the vicinity of the affected area 3 4, which elicited. 'Then, by pushing the cap 3 1 a which had been attached to cartridges 3 1 shows a first 0 Figure catheter 1 2, the catheter 1 through the cartridges 3 1 wherein said seal mechanism 1 2 a 2 proximal and continuously to the liquid-tight, perform feed operation for the carrier device 1 3, the artificial blood vessel 1 folded moved from cartridges 3 1 to the catheter 1 2 continues further to the affected area 3 4 headed forge ahead. During this time the situation is described in detail in supra literature {P CT / JP 9 6/0 1 34 7 (International Publication No. W09 6 Bruno 3 6 3 8 7)}.

At this time, can be performed by operating the tubing 2 2 phi base end side of the auxiliary operating lever 1 9 extends outside the body, the traction device 1 4 will follow moves incidental to the movement of the artificial blood vessel 1 . During this, the proximal end 1 4 a of B click mechanism 2 0 and traction device 1 4 provided on the base end 1 3 a conveying device 1 3 maintains a position extending to the outside through the sealing mechanism 1 2 a there. Also, the locking element 2 0 a, and the outer-locking elements 2 0 b among constituting the locking mechanism 2 0 is locked, is conveyed integrally with the auxiliary operating lever 1 9 and the operating rod 1 8. Therefore, the operation force applied to the tube 2 2 of the base end side is transmitted directly to the vicinity of the distal end portion 1 8 a of the operating rod 1 8 through the pipe member 2 1 of the proximal end portion 2 1 B.

As of optional these operations, and through the inner lock element 2 0 a and the outer locking element 2 0 b lock Organization 2 0, if necessary, the pipe member 2 1 and the operating lever 1 8 or pipe section, Ru can also be unlocked with the wood 2 1 and the tube 2 2. That is, as in the case of passing the curved parts of the body, when it is desired flexibility to have a auxiliary operating lever 1 9, the pipe member 2 1 and the tube 2 2 via the outer locking element 2 0 b unlock, Ru possible der that is retracted only tube 2 2 performs delivery operation only in the pipe member 2 1. Further, when it is desired to relatively move the pipe member 2 1 to the operating lever 1 8, it is also possible to unlock the two via the inner locking element 2 0 a.

If the artificial blood vessel 1 is disposed at the target position, as in the first 4 Figure-first 5 view, while holding the artificial blood vessel 1 in its position via the carrier device 1 3, retract the catheter 1 2 It is, to release the artificial blood vessel 1 from the catheter 1 2. Oite this back and forth, if necessary traction device using the 1 4 towing artificial, towards the rear of the vessel 1, can be the adjustment of installation position.

The first 6 Figure Consequently, the artificial blood vessel 1. Indicates a state was found was in close contact with the vessel. FIG at end wire ring 2, 3, 5, 5 A, the 6 or the like is not restored to a true circle, the vessel being driven by the ring-shaped linear portions 2 a beating, 3, 5, 5 A , in which shows a state in which the 6 and the like are raised slightly of the expansion operation. Finally, pull the wire 2 5 in conveying apparatus 1 3 proximal 1 3 a, further by pulling the base end 1 4 a of the wire 2 7 of the traction device 1 4, engagement of the artificial blood vessel 1 to release the finally taken out of the body of the carrier device 1 3 and the traction device 1 4. This makes it possible to implantation into purpose unit 'position serving the affected area 3 4 artificial blood vessel 1 is completed. As described above, this embodiment is not able to complete the implantation into the affected 3 4 artificial blood vessel 1, the artificial blood vessel 1 is effective as a means for preventing blockage of blood vessels in the affected area 3 4 restored after transplantation It will function in.

The artificial blood vessel 1, if allowed to attached in a state of engaging the carrier device 1 3 consisting of operating rod 1 8 及 beauty wire 2 5 As shown in advance Figure 6 detachably, user each time carrying since labor for set the device 1 3 to the artificial blood vessel 1 can be omitted, as possible out be subjected to immediate use to 掙入 the catheter 1 2 in situ.

On the other hand, carrier device 1 3 of the artificial blood vessel 1, since it comprises an auxiliary operating lever 1 9 for co capturing operating rod 1 8, also operating rod 1 8 be one but because fragile is flexible, until transported to the target position can tell the operating rod 1 8 directly operating force near the tip of the operating rod 1 8 without relying on the strength of itself through the auxiliary operating lever 1 9, the operating rod 1 8 bent on the way transportation the and would inconvenience Ru can be effectively prevented.

Furthermore, since the separable against integrally transportable 且 one operating rod 1 8 auxiliary operating lever 1 9 together with the operation lever 1 8 via the lock mechanism 2 0 provided on the base end side 1 3 a, auxiliary the connection state between the steering Saku杆 1 9 and the operating lever 1 8 can you are sure, the auxiliary operating lever 1 9 releases the connection at any time through the operation on the base end 1 3 a when no longer needed an auxiliary operating lever 1 9 can be retracted Te.

On the other hand, an auxiliary operating lever 1 9, the operating rod 1 8 tip 1 8 a and the pipe member 2 1 disposed at a position that may be fitted in, by connexion group to continuously provided in the pipe member 2 1 constitute an operating force is found in addition to the end side from the tube 2 2 which is transmitted to the distal end portion 1 8 a vicinity of the operating rod 1 8 through the pipe member 2 1 tare Runode, externally fitted to the pipe member 2 1 the can and child transmitting the operating force while reinforcing the front end portion near the operating rod 1 8, also transmitting the pipe member 2 separately Ju Bed 2 2 to 1 continuously provided to the operating force on the pipe member 2 1 to reason, as compared with the case where pulling out the pipe member 2 1 with a strength it proximally, the lead in the body to adopt a flexible path I flop member 2 1 with a flexible part in the middle operating force it can be suitably carried out.

Further, the pipe member 2 1, and the large diameter portion 2 1 A of the tip, a small diameter is housed in the large diameter portion 2 1 A of the proximal end and provided continuously become side the tube 2 in the 2 base part 2 1 constructed from a B ', the locking mechanism 2 0, and the locking element 2 0 a inner selectively locking the pipe member 2 1 a proximal end portion and the operating rod 1 8, the pipes member 2 1 since the structure and an outer locking element 2 0 b for selectively locking the proximal end and the tube 2 2, the pipe member 2 1, Ji, Interview "Bed 2 2 twin side constituting the auxiliary operating lever 1 9 the operating lever 1 can the child a connection to 8 more reliable ones, also by operating the two locking element 2 0 a, 2 O b, and the this easily performed even these release as needed it can.

Further, the pipe member 2 1 and the one made of metal, the tube 2 2 Since the made of resin, it is possible to maintain the strength of the connecting portion between the auxiliary operating rod 1 9 capturing the operation lever 1 8 and further, that Do can be transmitted to the vicinity of the distal end of the auxiliary operating lever 1 9 proximal to more suitably operating rod 1 8 operating force applied.

Further, since the fitted pipe member 2 1 constituting the auxiliary operating lever 1 9 catching the connecting part between the tube elements 1 8 B and the tube connecting element 1 8 C proximal, their base end Chu near-elements 1 8 B and the tube connecting element 1 8 base end side of the connecting portion is C, it is possible to effectively prevent the region indicated by symbol X is bent in Figure 8, for example.

In addition, as described above, and those made of three cylindrical bodies tubes connecting element 1 8 C, since than the center of the cylinder to the other are the long, both tubular element 1 8 A, 1 when using 8 B by bending, the tube connecting element 1 8 C and the tubes elements 1 8 a, 1 8 without excessive force is applied to the connecting portion 1 8 c of B, and the connecting portion 1 8 in c around will be the tube connecting element 1 8 C overall elasticity length 'smoothly changes in the longitudinal direction, as possible out to ensure the natural curved state between the tube elements 1 8 a, 1 8 B.

The present invention is not limited to the above embodiments, without departing from the scope of the present invention, various modifications are possible.

For example, transporter 1 1 3, as shown in the first FIG. 7, the rearward junction of the operating rod 1 1 8 the proximal end side of the tubular element 1 1 8 B and tubes connecting element 1 1 8 C headed covered with a cup-shaped cylindrical body 1 1 8 BB you opening, the cylindrical body 1 1 8 BB inner empty Tosuke operating lever 1 1 9 of the pipe member 1 2 1 of the distal end portion 1 2 1 a of even those of 揷入 configurations not good.

As long as such a configuration, the connecting portion and the strength of the vicinity of the operating rod 1 1 8 and the auxiliary operating lever 1 1 9 it is possible to Totsuyo by cylindrical body 1 1 8 BB, above Examples same effect as is obtained.

In addition, carrier 2 1 3, as shown in the first FIG. 8, the tube elements 2 1 8 on the base end side of the operation lever 2 1 8 B and tubing connecting element 2 1 8 connecting portion 2 1 of the C and 8 c, it may be of the auxiliary operating lever 2 1 9 of the pipe member 2 2 1 tip 2 2 1 is brought close to the a configuration. Be of such a configuration, the same operation and effect as the above embodiment can be obtained. In this case, not necessarily for the tip 2 2 1 eighth pipe member 2 2 1 need not be a large diameter, it is not necessary to use a special pipe member 2 2 1.

Of course, the auxiliary operating rod to assist the operating rod, for example in the first embodiment is constituted from the pipe member 2 1 and the tube 2 2 which only the pipe member 2 1 optionally or only tubing 2 2 in can also be configured. That it uses what is called a so-called balloon catheter tube 2 2 are possible. Moreover, the carrying device, but it may also be one that is constituted only by wires to be 揷通 its inner periphery and the operating rod without a cord. In that case, leave form larger form the front hook portion of the artificial blood vessel, the front hook it suffices engage the wire.

<Second Embodiment>

Next, a second embodiment of the present invention will be described with reference to the first 9 FIG-second 9 FIG.

Basic artificial blood vessel 1 and that occasion Ri fold how to apply this embodiment is of the substantially same manner as in Example, the introduction of the catheter 1 2 to the discharge from the catheter 1 2 at the target position process was carried out while holding folded by the holding means 1 1 artificial blood tube 1 as shown in the second FIG. 7, in that so as to release the holding state of the holding means 1 1 after release, the It differs from the first embodiment.

The explanation below focuses on the differences from, the description of mediation in particular does not require parts of the described common portions will be omitted as appropriate.

The holding means 1 1, the encapsulant 1 5, and a linear body 1 6 for holding the encapsulant 1 5 in a cylindrical shape.

Specifically, encapsulant 1 5, those artificial blood vessel 1 order to encapsulate are those that telescopic braided in a mesh shape as shown the warp and weft in the first 9 figures, and it serves as a Ryakutaira face manner in a deployed state. Each intersection of warp and weft are woven by the intersection respectively, in which the eye to be formed between the intersection to realize the expansion of the dressing 1 5 entire vertical and horizontal directions by stretching.

On the other hand, linear body 1 6 is intended flexible being made of nickel titanium alloy, heavy as the whole edge portions of the encapsulant 1 5 as shown in the second 0 Figure is schematic tubular engaged, it is to hold the the envelope material 1 5 into a cylindrical shape by 揷通 the linear body 1 6 as stitching between the polymerized edges 1 5 a, 1 5 b like a dashed line.

Then, the inside of the encapsulant 1 5 of the holding means 1 1, with the tubular member 3 3 1 having a funnel-shaped tube 3 3 0 at one end as shown in the second 1 figure collapsed artificial blood vessel 1 in that to accommodate.

That is, first encapsulant 1 5 while holding the tubular by the striatum 1 6, tapered surfaces 3 3 a tip that has been previously inserted into the tubular member 3 3 1 As shown in the second 1 Figure the encapsulant 1 5 Guide member 3 3 2 of the distal end that having a 2 a so on are fitted. to covered state to the outer periphery of the tubular member 3 3 1 as shown in the second 2 Figure . Then, as shown in the second 3 Figure, along the tapered ¾ funnel-shaped tube 3 3 0 揷入 folding the artificial blood vessel 1 from one end 3 3 1 a side of the cylindrical member 3 3 1. Further, in order to move the human E vessel 1 with the tubular member 3 3 within 1 uses a luck transportable device 1 3.

In this case, as in the first embodiment, split point 6 a vascular prosthesis 1, 6 b, 6 c, 6 d 2 points 6 you opposed by sandwiching an inner axis of a, 6 c forward so that the top of the mountain toward and 窣引 toward the distal end side of the artificial blood vessel 1 forward by transport So匱 1 3. Thus, before the auxiliary-ring end wire 6 dividing point forward 6 a, 6 c becomes the top of the chevron, other. Division point 6 b, 6 d becomes the bottom of the valley-shaped, as a whole It is bent in a regular wavy. Further, it bent other-ring end wire 2, 5, 5 A, 6, 7 also folded in a wave of the same phase. At this time, the division point 6 a, 6 b, 6 c, 6 d and dividing point 6 b, 6 c, 6 d, 6 a hook portion 8 before four locations formed in the middle of the Yamagata forward It will be located intermediate the bottom of the top and valley. In this manner, loaded with second 3 encapsulated as shown in FIG, folded force Tori Tsu di 3 3 artificial blood vessel 1 on the inner periphery of 1 corresponding to the mounting position of the timber 1 5.

Thereafter, in the cartridge 3 3 1 at the other end 3 3 1 b, and a portion of the packaging material 1 5 and the artificial blood vessel 1 such as pinched fingers simultaneously in a position indicated by the second 4 in the arrow p mutually restrained, the cartridges 3 3 1 in this state is retracted relative to their restraining portion, a relatively encapsulant 1 5 and artificial blood vessel 1 to be withdrawn simultaneously from cartridges 3 3 1 Therefore, it charged the artificial blood vessel 1 sequentially inside the 披包 material 1 5. Then, by extracting the full cartridges 3 3 1 As finally shown in 2 5 Figure, the artificial blood vessel 1 is accommodated in the dressing 1 in 5 in a state folded folding.

The second 6 figure shows the artificial blood vessel 1 folded Ri folding the holding means 1 1 as described above.

Next, the body of the eye position of the formed artificial blood vessel 1 as described above, namely the introduction procedure to implant in transported to the affected area 3 4 will be described.

First, as shown in the second FIG. 7, for example, is introduced to the catheter 1 2 from femoral artery of the base F of the foot becomes a sealing mechanism 1 2 a proximally into the body, the tip artery positioned in the vicinity of the affected area 3 4 that caused the aneurysm or the like. Their to be introduced into the catheter 1 within 2 artificial blood vessel 1 folded by the holding means 1 1 the carrying device 1 3 and the traction device 1 4. To, by operating the tube 2 2 of the base end side of the auxiliary operating lever 1 9 capturing that extends outside the body, it performs shift operation against the carrier device 1 3, with bands traction device 1 4 artificial blood vessel 1 It transported to the affected area 3 4 aimed in a state obtained by. At this time, one end 1 6 a linear body 1 6 holding means 1 1, carrying So脣 1 3 of the base end 1 3 locking mechanism provided in a 2 0 and Yasushi引 device 1 4 of the base end 1 4 a is through the sealing mechanism 1 2 a extends from the body.

More specifically, as in the first embodiment, while locking the lock mechanism 2 0, transporting the artificial blood vessel 1 to the vicinity of the affected area 3 4 by conveying apparatus 1 3. Thereafter, releasing an artificial blood vessel 1 from the force catheters 1 2. The artificial blood vessel 1, Runode are also retained a folded state by the holding means 1 1 after release, it is not always necessary to release at a predetermined position, after release, the carrier device 1 3 optionally the traction device 1 4 it is possible to perform the positional adjustment with.

If the artificial blood vessel 1 is disposed in the proper position, as shown in the second 8 figure pulled out encapsulant 1 5 linear body 1 6 that holds the holding means 1 1.

Specifically, first, to release the encapsulant 1 5, constraint against the artificial blood vessel 1 by pulling one end 1 6 a linear body 1 6 and the respective portions of the artificial blood tube 1 is expanded by sequentially 弹性It is restored to the state of close contact with the inner wall of the blood vessels of the affected part 3 4. The second 9 FIG This result is shows the state in which the artificial blood vessel 1 was brought into close contact with the vessel. Finally, as in the first embodiment, by pulling the wire 2 5 of conveying device 1 3 and the wire 2 7 of the traction device 1 4, to release the engagement between the artificial blood vessel 1, transporter gamma 3 and finally taken out of the body of the traction device 1 4. This makes it possible to implantation into the target site serving the affected area 3 4 artificial blood vessel 1 is completed. The encapsulant 1 5 dissociated left in place along with the artificial blood vessel 1 ', it may be removed only linear body 1 6, taken from the body to go to separately capture 披包 material 1 5 as needed it is also possible.

As described, according to the above method, the artificial blood vessel 1 becomes to function effectively as a means to prevent blockage of blood vessels in the affected area 3 4 restored after transplantation, the same effect as the first embodiment achieve the. Furthermore, since the state is retained folding the artificial blood vessel 1 by the encapsulant 1 5, it is possible to more reliably prevent the deformation of the middle transport the artificial blood vessel 1. Moreover, even if the tying artificial blood vessel 1 the same, if vMedia.Creating surrounds the entire artificial blood vessel 1 with encapsulating material 1 5 as this locally convex occurs in folded outer surface of the artificial blood vessel 1 Hateful. Therefore, it is possible to minimized the resistance during transportation, yet ,, artificial because it caused to expand dressing 1 5 in the affected area 3 4 serving the target position, the surrounding vascular prosthesis 1 is folded is wide open returning operation to the predetermined shape of the vessel 1 can also be carried out promptly.

Also, if folding the artificial blood vessel 1 thus advance by the holding means 1 1, every use, since the work of folding folding the artificial blood vessel 1 is not necessary, the task of installing the catheter 1 2 artificial blood vessel 1 rapidly it is possible to perform in.

Furthermore, employs a method by sewing in linear body 1 6 holds the dressing 1 5 in a tubular shape, it may expand the particular good connexion encapsulant 1 5 unplugging draw a linear body 1 6 so can be easily held in a state wound with encapsulant 1 5, Furthermore, the holding state of the packaging material 1 5 by hand in unplug pulling leading the linear body 1 6 in the longitudinal direction it can be directly released by a relatively small resistance to. Furthermore, it is possible to reliably perform release operation according even from a remote location.
