Description
Technical field
The utility model relates to medical instrument, especially a kind of local densification bracket.
Background technique
Aneurysm is Common Cardiovascular Disease, and lethality is high if rupture.With the development of interventional technique, encephalic
The appearance of bracket greatly improves the curative effect of interventional therapy intracranial aneurysm.Current clinically main support technology includes propping up
Frame secondary spring circle Embolization, blood flow guiding device implantation, etc..Bracket secondary spring circle embolism can change aneurysm neck
The hemodynamic state at place, " scaffold " for changing parent artery curvature, playing the role of vascular endothelial growth.Blood flow guiding
Device can change intra-arterial hemodynamic state and induce thrombosis in aneurysm.
But, the intravascular stent of the prior art still has some defects.
For example, in bracket secondary spring circle embolism interventional procedure, it is sometimes desirable to pass through bracket net by microtubular
Eye conveys spring ring to clog aneurysm cavity, and microtubular passes through the difficult of bracket gap and due to easily wearing out when operation
Vascular tissue, not only risk is higher, and cost is also higher.In addition, there are aneurysms to answer after bracket secondary spring circle Embolization
Hair, risk of rupture.
For another example, be change aneurysm cavity blood flow state induce tumor in thrombosis in favor of cure, it is desirable to bracket have compared with
High metal coverage rate.For example, clinically the Pipeline bracket of metal coverage rate 30% or so can be used to be intervened at present
Treatment.The metal coverage rate of intravascular stent described herein refers to: the metal covering area in bracket accounts for the ratio of the bracket gross area
Example.However, backbone metal coverage rate is higher, then its radial tension increases, and compliance is deteriorated；On the other hand, bracket has higher
Although metal coverage rate can effectively change dynamics of arterial flow state, the blood flow of even blocks perimeter blood vessel may be interfered
And additional injury is caused to patient.In addition, blood flow guiding device implantation surgery is expensive.

Detailed description of the invention
Fig. 1 is the structural schematic diagram of the local densification bracket of embodiment according to the present utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, described embodiment is only the utility model a part of the embodiment, rather than is all implemented
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment according to the present utility model provides a kind of local densification bracket, keeps being suitble to flexibility on the whole
Aneurysm region blood flow preferably can be prevented or reduce simultaneously to cure in favor of realizing.
Embodiment according to the present utility model provides a kind of local densification bracket, to contain the blood of aneurysm structure
Guan Zhong, comprising:
Close mesh portions, inner hollow, and extend to second end from first end and whole in a tubular form and there is circular section
Face, the close mesh portions pass through the webbed wall construction of metal wire knitted shape；
First thin mesh portions, form the tubular structure of inner hollow by metal wire knitted, from the close web frame
First end first free end with outward bell shape is extended outwardly to far from the center of the close web frame；
Second thin mesh portions, form the tubular structure of inner hollow by metal wire knitted, from the close web frame
Second end second free end with outward bell shape is extended outwardly to far from the center of the close web frame；
Wherein the tubular structure of the close mesh portions, the first thin mesh portions and the second thin mesh portions connects in inside
Logical, the metal coverage rate of the close mesh portions is 30% or more, the gold of the first thin mesh portions or the second thin mesh portions
Belonging to coverage rate is 15% or less.
In this way, at least part of close mesh portions is directed at aneurysm knot in the local densification bracket of the integral type
The opening is effectively closed at structure opening (that is, tumor neck is open), is dredged since the metal coverage rate of close mesh portions is greater than first and second
Mesh portions, thus its closure be higher than the first and second thin mesh portions, it is thus possible to preferably closing aneurysm structure, prevent or
The blood for reducing aneurysm cavity flows into favor of realizing and curing.
On the other hand, since close mesh portions need the width slightly larger than aneurysm structural openings only to realize that aneurysm mouth seals
It closes, thus the length of close mesh portions only accounts for lesser ratio in the total length of the local densification bracket of integral type, and its
Remaining part point (that is, first and second thin mesh portions) still keeps preferable flexibility since metal coverage rate is lower, makes the office
Portion's densification bracket still has preferable flexibility on the whole, easily enters focal area positioning.
Further, since the first and second thin mesh portions keep lower metal coverage rate, thus mesh with higher is close
Degree, so that the gap of the mesh reserved in its wall construction is enough that blood flow is allowed to pass through, thus in closing aneurysm structural openings
Blood flow will not be interfered to pass through the other blood vessels in periphery simultaneously.
In addition, the first and second thin mesh portions can make the local densification bracket of integral type fixed being suitble in the blood vessel
Position keeps its difficult to slide.
It should again be emphasized that due to the specially designed structure of the local densification bracket, thus in intervention operation not
The operation for needing to carry out to clog bracket mesh again with spring ring, can not only significantly reduce operating difficulty and risk, and can also
Enough reduce cost.
