Description
Technical field
A kind of dress be combined the utility model relates to PMVSD occluder device and bare bracket, for treating dissection of aorta
It sets, belongs to the field of medical instrument technology.
Background technique
Stanford Type B dissection of aorta (TBAD) is one of the danger disease in cardiovascular disease, and feature is that morbidity is unexpected,
Rapidly, it is high that acute stage disease sends out the death rate for development.The primary treatment regimen of TBAD is aorta pectoralis endovascular repair (TEVAR),
Principle is to block inner membrance tearing port using overlay film frame, improves true chamber perfusion, completely cuts off false chamber blood flow, promotes false intracavitary thrombus shape
At then promoting that true chamber expands and false chamber reduces, prevent false chamber Ectasia and rupture.
Good plugging effect may be implemented in descending aorta distal end in overlay film frame, but when tearing port is close to left clavicle
When lower arterial ostium, after overlay film frame normally discharges, blood flow normal flow direction left subclavian artery can be stopped, cause blood supply insufficiency,
Cause a series of complication.
Common plugging device is applied to the case of TBAD treatment, and there is also but when tearing port is open close to left subclavian artery
When, after plugging device implantation, upper disk surface can have the wind for causing blood vessel breakage, arterial hamorrhage always with left subclavian artery friction
Danger, and after plugging device implantation, arterial blood flow velocity quickly, washes away always plugging device, and plugging device is be easy to cause to shift.
Utility model content
The technical problems to be solved in the utility model is in aortic dissection, when tearing port moves under left clavicle
When arteries and veins is open, the friction of plugging device and left subclavian artery how is avoided, and how to avoid the displacement of plugging device.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of for treating dissection of aorta
Combination unit, it is characterised in that: including
For being discharged into aortic tunica intima tearing position, and the PMVSD occluder device being bonded with blood vessel；With

Preferably, the PMVSD occluder device is woven by nitinol alloy wire.
Preferably, the upper disk surface, be equipped with polyester choked flow film in lower disk.
Preferably, the lower wall face is symmetrical, and the lower steel bushing is set to the center of lower disk lower part.
Preferably, the lower steel bushing tail portion and the bottom of lower disk maintain an equal level.
Preferably, the bare bracket main body is woven or is cut by nickel-titanium alloy material.
Preferably, the bare bracket main body is equipped with for increasing the visual developing mark in art.
It is highly preferred that the developing mark is set to the both ends of the bare bracket.
Preferably, the bare bracket body surfaces are covered with the hydrophilic of the smoothness for increasing its biocompatibility and conveying
Coating.
The combination unit provided by the utility model for being used to treat dissection of aorta is in use, first by the method for intervention
PMVSD occluder device is discharged into aortic tunica intima tearing position, bare bracket main body is discharged to interventricular septum by intervention approach later
Plugging device implant site is bonded PMVSD occluder device further with blood vessel, reinforces plugging effect, while fixed interventricular septum
Plugging device avoids it from being displaced.
The utility model blocks tearing port using PMVSD occluder device, further fixes interventricular septum using bare bracket main body and seals
Stifled device is realized and is blocked completely.Apparatus structure is reasonable, is particularly suitable for the ventricular septal defects close to left subclavian artery, energy
Dissection of aorta tearing port close to left subclavian artery is safely and effectively blocked.
Compared with overlay film frame or Occluder is used alone close to the dissection of aorta of left subclavian artery, this is practical
It is novel to have the following beneficial effects:
1, the PMVSD occluder device design in the utility model can contact to avoid upper disk surface with left subclavian artery,
Under the premise of avoiding upper disk surface abrasion blood vessel from causing the risk of arterial hamorrhage, realizes and block completely；
2, in the utility model bare bracket main body use, fixed effect is played to PMVSD occluder device, is avoided between room
Every generation shifting phenomena under washing away of the plugging device in the faster arterial blood of flow velocity.
