Abstract
The invention discloses a kind of vascular dissection breach plugging devices, belong to medical blood vessel intervention apparatus technical field.The present invention blocks problem for dissection of aorta distal end cut, provides a kind of dissection of aorta distal end cut plugging device, and anti-Hemostatic Oral Liquid pours in down a chimney from interlayer distal end breach into false chamber.The device includes that flexible bag, position fix and support component two parts, wherein flexible bag part is put into interlayer vacation chamber by interlayer distal end breach by interventional method, in it by conduit inject hydrogel etc. can liquid injection subsequently become and stablize the content of not flow regime and be filled, wherein position fixes and supports component other than interlayer distal end breach, the true chamber of aorta is with inner, for fixing flexible bag, prevent to shift.
Description
Technical field
The present invention relates to a kind of intravascular plugging devices, and in particular to a kind of dissection of aorta breach closure instrument.
Background technology
The aorta of human body is made of inner membrance, middle film and external mold, and dissection of aorta refers to aortic tunica intima breach occurs,
Middle film is torn under a variety of causes effect, and blood enters to form false chamber and extend under pressure.Dissection of aorta meeting
The normal blood supply for influencing aorta and bifurcated artery, is a kind of breakneck vascular diseases, and lethality is high.
The true chamber of blood vessel is often strutted by the method for intervention support or overlay film frame in clinic, compressing vacation chamber reaches treatment mesh
's.But when for extending to the more position of aortic bifurcation (such as the positions such as the arteria renalis, mesenteric artery), overlay film frame
Implantation is easy to block branch vessel entrance, influences branch vessel blood supply, becomes stubborn problem in clinic.At present for extension compared with
Long abdominal aneurvsm is generally only interlayer proximal part rent to be implanted into overlay film frame, and be not processed to interlayer distal end.
This processing the result is that there is blood in some patientss pours in down a chimney from interlayer distal end cut into interlayer vacation chamber and then oppressing true chamber
Phenomenon increases postoperative complications, causes suffering to patient.
Invention content
The technical problem to be solved by the present invention is to：A kind of dissection of aorta distal end cut plugging device, anti-hemostasis are provided
Liquid pours in down a chimney from interlayer distal end breach into false chamber.
In order to solve the above technical problem, the present invention provides a kind of dissection of aorta distal end cut plugging device, the dresses
It sets and fixes and supports component two parts including flexible bag, position, wherein flexible bag part passes through intervention by interlayer distal end breach
Method is put into interlayer vacation chamber, in by conduit inject hydrogel etc. can liquid injection subsequently become and stablize in not flow regime
Tolerant to be filled, wherein position fixes and supports component other than interlayer distal end breach, and the true chamber of aorta is with inner, for solid
Determine flexible bag, prevents to shift.
The flexible bag and position fix and support in the blood vessel interposing catheter that component can receive stock size, to lead to
Interventional method is crossed to be put at the breach of vascular dissection distal end.
The flexible bag outer surface can be designed to, with structures such as cellular, lint shapes, be conducive to more preferable sealing and surface
Form thrombus.
The flexible bag can be put into false intracavitary before injecting content by interlayer distal end breach, then by leading
After pipe injects content, gradually full flexible bag can be full of the false chamber of the irregular shape near interlayer breach, wait for content
It is formed to sufficiently sealed at the breach of interlayer distal end after gelled, anti-Hemostatic Oral Liquid is poured in down a chimney by interlayer distal end breach such as false chamber
It is interior.
The position, which fixes and supports component, can play the role of two aspects, one：The shape of true chamber is maintained after strutting
Shape prevents flexible bag from filling extruding of the process to true chamber, secondly：Prevent the flexible bag after implantation from being slipped toward proximal part.
The flexible bag need to meet biocompatibility requirement.
The position fixes and supports component, and overhead structure can be arranged, convenient for being more fixedly secured.
The plugging device is equipped with multiple agent localization points in close, distal end outer rim and flexible bag.
The present invention fixes and supports member two parts by flexible bag and position and constitutes.Flexible bag is after injecting content
It is mainly used for the closure of artery dissection distal end cut, anti-Hemostatic Oral Liquid pours in down a chimney into interlayer vacation chamber.Position fixes and supports structure
Part is mainly used for keeping the true chamber shape of artery and fixed flexible bag position.In addition, the anchor point arranged in the present invention can be helped
Conveying and injection content is helped to obtain the more preferably visual field and position detection accuracy under Angiography in the process.
Description of the drawings：
Fig. 1 is the structural diagram of the present invention, and wherein A is flexible bag compressive state, and B is compressed bag expanded state；
Fig. 2 is another design method that position fixes and supports component；
Fig. 3 is another design method that position fixes and supports component；
Wherein reference numeral is：Vascular wall 1, artery dissection 2, barb 3, position fix and support component 4, flexible bag 5, lead
Pipe 6.
Specific implementation mode：
The present invention is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention fixes and supports component 4 by flexible bag 5, position, injection catheter 6 is constituted, wherein elasticity
Bag 5 fixes and supports 4 side of component with position and is connected, and flexible bag 5 takes in the inside of injection catheter 6 when initial, and together with position
It fixes and supports component 4 and shrinks together and be put into interposing catheter.It is identical to fix and support that component 4 can be as shown in Figure 1 for position
The appearance that caliber, one end caliber expansion that also can be as shown in Figure 2 or Figure 3 or both ends caliber are expanded.It is seen by image in operation
Equipment is examined, the present invention is moved to the vessel segment where artery dissection cut through arterial system with interposing catheter, by injection catheter 6
End is put into artery dissection cut, and position, which is then fixed and supported component 4, expands, then by injection catheter 6 to flexible bag 5
The substances such as interior injection hydrogel (optional polyethylene glycol polyethylene glycol), content to be implanted becomes gel state
After withdraw from injection conduit 6, reach and fall Anomalistic space filling and sealing, anti-Hemostatic Oral Liquid on the inside of interlayer vacation chamber cut by cut
The purpose of stream.
