Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of intravascular stent system and application method.
Background technology
At present, angiocardiopathy turns into one of principal disease for threatening human health and life, and intravascular stent is as the heart
The critical treatment means of vascular diseases are widely used.Over the course for the treatment of, intravascular stent is implanted in the blood vessel of human body,
Reach the purpose for treating and preventing the vascular diseases such as hemadostewnosis, obstruction, aneurysm and interlayer.
Existing intravascular stent system generally includes radial expansion sacculus, is arranged in the sacculus dilating catheter of balloon center,
And it is wrapped in the radial expansion support of radial expansion sacculus outer surface.When vascular lesion is treated, center seal wire passes through sacculus
Dilating catheter, intravascular stent system reach target lesion position in blood vessel along center seal wire, then expand radial expansion sacculus by footpath
Discharged to telescope support at target lesion position.But because blood vessel is bifurcated, when two of bifurcated vessels or triple vessel disease
When, then need several supports being discharged into the blood vessel of lesion, existing structure need under X-ray machine, operate another seal wire from
Discharge by reaching another blood vessel in intravascular stent system, its operation difficulty is big, wastes time and energy, and positioning accuracy
Difference；Meanwhile when only having lesion in vascular bifurcation opening, radial expansion support is difficult that lesion locations are completely covered, for not shadow
Another branch vessel or protection branch vessel of no lesion are rung, then needs to be accurately positioned radial direction telescope support, and it is existing
Operating method be under X-ray machine, repeatedly with different throwings according to position operation positioning, its complex operation, positioning accuracy are poor.
Led in order to solve the above technical problems, providing a kind of reserve in Chinese utility model patent CN201320895986.4
The support of silk passage, it is provided with the reserved silk guide passage passed through for additional seal wire, and which obviating seal wire needs to pass through in the blood vessel
The problem of having discharged support complex operation, improve support positional accuracy.But the problem of presently, there are is to usually require treatment
Blood vessel all between 2~5 millimeters, narrow blood vessel that intravascular stent system passes through then needs to be less than 2 millimeters, therefore intravascular stent system
Unite smaller more easily by ensure effective treatment at vascular lesion position, therefore, in the case of the reserved silk guide passage of increase
How to manufacture small size intravascular stent system turns into urgent problem to be solved.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of service life and security
Height, and can be applied to the intravascular stent system and application method with seal wire reserved passageway of narrow and small blood vessel.
In order to solve the above technical problems, technical scheme proposed by the present invention is：
A kind of intravascular stent system, including radial expansion sacculus, the balloon expandable that is arranged in radial expansion balloon center are led
Pipe, and the radial expansion support of radial expansion sacculus outer surface is wrapped in, the radial expansion sacculus and radial expansion support
Between be enclosed with the seal wire reserved passageway passed through for additional seal wire, being provided with seal wire reserved passageway in the seal wire reserved passageway protects
Pipe and protection pipe filling member, the inwall of the seal wire reserved passageway are bonded with the seal wire reserved passageway protection pipe, the protection
Pipe filling member is filled in the seal wire reserved passageway protection pipe.
Further improvement as above-mentioned technical proposal：
The radial expansion support is provided with multiple through holes passed through for additional seal wire, the seal wire reserved passageway protection pipe
Seal wire through-Penetration portion corresponding with through hole is provided with, the seal wire through-Penetration portion is axial for through hole or along seal wire reserved passageway protection pipe
What is set runs through groove.
The seal wire reserved passageway protection pipe is seal pipe, and the seal pipe is provided with the thorn that entrance is punctured for additional seal wire
Broken portion.
The radial expansion sacculus and radial expansion support are stretched out in the one or both ends of the seal wire reserved passageway protection pipe.
The radially flexible sacculus of the seal wire reserved passageway protection pipe it is axial arranged, and led parallel to the balloon expandable
Pipe.
The radial cross-sectional shape of the seal wire reserved passageway protection pipe is ellipse, circular or polygon.
The protection pipe filling member can be along the axial movement of seal wire reserved passageway protection pipe.
The outer surface of the protection pipe filling member is bonded with the inner surface of the seal wire reserved passageway protection pipe, and the guarantor
The seal wire reserved passageway protection pipe is stretched out in the both ends or one end of pillar filling member.
Sink into be formed in radial expansion sacculus in the seal wire reserved passageway；Or seal wire reserved passageway is radial expansion branch
Frame is prominent and is formed；Or seal wire reserved passageway is caved in protrude with radial expansion support by radial expansion sacculus and is collectively forming.
A kind of application method of intravascular stent system described above, comprises the following steps：
(1) the protection pipe filling member in seal wire reserved passageway protection pipe is taken out；
(2) additional seal wire is passed out of seal wire reserved passageway protection pipe, by center seal wire from balloon expandable centre pipe
Pass；
(3) seal wire reserved passageway protection pipe is taken out；
(4) radial expansion sacculus and its contained radial expansion support are moved to correspondingly along center seal wire and additional seal wire
Vascular lesion position, carry out vascular lesion treatment.
Compared with prior art, the advantage of the invention is that：
The present invention is provided with seal wire reserved passageway protection pipe and protection pipe filling member, protection pipe filling in seal wire reserved passageway
Part is supported in seal wire reserved passageway protection pipe, which obviate seal wire reserved passageway and seal wire reserved passageway protection pipe production and
Caused compression, deformation and bending, ensure that the peace of intravascular stent system in the production and use process during before use
Full reliability；And after protection pipe filling member detaches, seal wire reserved passageway protection pipe can avoid hard and sharp keen guidewire tip from existing
By the infringement during the passage to radial expansion sacculus and radial expansion support, it effectively increases intravascular stent system
Service life and security.Meanwhile the inwall of seal wire reserved passageway is bonded with seal wire reserved passageway protection pipe, it causes in seal wire
The diameter of passage is allowed in reserved passageway production process as far as possible, so as to reduce the straight of seal wire reserved passageway to greatest extent
