Abstract
The utility model relates to a balloon for dilating vascular stenosis, in particular to a coronary artery dilation balloon matching with the structure of coronary artery, which aims at solving the problems that the common dilation balloons easily result in incomplete vascular dilation or vascular avulsion during vascular stenosis dilation due to uniform diameter which does not match with the normal physical anatomical structure of the coronary artery. The coronary artery dilation balloon comprises a balloon body, a distal terminal positioned at the distal end of the balloon body and a proximal terminal positioned at the proximal end of the balloon body; and the balloon body is a cylinder with the diameter gradually increasing, and the uniform increase of the diameter of the balloon within each 10mm length is 0.1mm-0.15mm. As the balloon body with the diameter gradual increase structure is coincident with normal physical anatomical structure of the coronary artery, the situations of incomplete vascular dilation occurred in the common dilation balloon which adopts the diameter of stenosis distal end or vascular avulsion caused by adopting the diameter of the stenosis proximal end can be avoided.
Description
Technical field
This utility model relates to a kind of dilating sacculus of blood vessel dilating stenotic lesion, relates in particular to a kind of coronary dilation sacculus that meets the coronary anatomy physiological property.
Background technology
At present, handling the used sacculus of coronary stenosis is the diameter homogeneous, does not meet the The normal anatomic and physiological of arteria coronaria just because of the diameter homogeneous of sacculus, just causes the balloon expandable vascular lesion that the generation of vascular tear situation is arranged constantly.In addition, when handling tortuous calcify lesion, because the homogeneity of balloon diameter; For preventing vascular tear, many " normally " blood vessel diameters with the pathological changes far-end are reference when choosing balloon diameter, so select the result of balloon diameter to be: the expansion of vascular lesion near-end is insufficient; The projection that is prone to remaining calcify lesion is in lumen of vessels, and when making follow-up propelling movement support, support is difficult to through maybe not passing through the vascular lesion near-end; The result who has caused so is: or use the large size sacculus again instead and expand again, or adopt other technologies such as two seal wires, so that support arrives assigned address; Like this, not only increased operation (meaning that doctor and patient has all increased the amount of radiation of accepting the X line, is unfavorable for healthy) consuming time; Also increased patient's financial burden; In addition, using the large size sacculus instead just has the possibility that causes vascular tear, brings due to the complication painful to the patient thus.
Summary of the invention
In order to solve the The normal anatomic and physiological structure that common dilating sacculus diameter homogeneous does not meet arteria coronaria; Cause the technical problem of the insufficient or vascular tear of vasodilation during the balloon expandable vascular lesion easily, this utility model provides a kind of coronary dilation sacculus that closes arteria coronaria The normal anatomic and physiological structure.
The technical scheme of this utility model:
A kind of coronary dilation sacculus; Form by utricule part, the proximal head that is positioned at the distal head of utricule far-end and is positioned at the utricule near-end; Its special feature is; Said utricule is that the even cumulative amount of utricule diameter is 0.1mm ~ 0.15mm in every 10mm length from the even cumulative drum of utricule far-end to utricule proximal diameter.
The beneficial effect of this utility model:
Compare with common dilating sacculus, the utricule of coronary dilation sacculus no longer is the drum of diameter homogeneous, but the utricule diameter is evenly cumulative from utricule far-end to utricule near-end, demonstrates the thick cylindrical structure of the thin near-end of far-end; This utricule structure is almost consistent with the The normal anatomic and physiological structure of arteria coronaria, has therefore effectively avoided adopting the common dilating sacculus of pathological changes distal diameter to cause vasodilation common dilating sacculus insufficient or employing pathological changes proximal diameter to cause the generation of vascular tear situation.
Description of drawings
Fig. 1 is a coronary dilation balloon configuration sketch map;
Among the figure, 1. utricule, 2. distal head, 3. proximal head.
The specific embodiment
In conjunction with Fig. 1 this utility model is described:
A kind of coronary dilation sacculus is made up of utricule 1 part cylindraceous, the proximal head 3 that is positioned at the distal head 2 of utricule 1 far-end and is positioned at utricule 1 near-end; The diameter of said utricule 1 is evenly cumulative from utricule 1 far-end to utricule 1 near-end, is cumulative standard with the even cumulative 0.1mm ~ 0.15mm of utricule 1 diameter in every 10mm length.Promptly compare with utricule 1 diameter of utricule 1 other positions, utricule 1 diameter of the utricule 1 diameter minimum of utricule 1 far-end and utricule 1 near-end is maximum.
The utricule 1 Diameter Gradual Change amplitude of the coronary dilation sacculus that this utility model provides is the true diameter that combines the arteria coronaria blood vessel that clinical coronary angiography showed; The Statistics Application method, thus find out the result that blood vessel diameter is drawn by the cumulative rule of blood vessel far-end to near-end.
In order to satisfy the blood vessel difference of Different Individual: in every 10mm length the scope of the even cumulative amount of utricule 1 diameter be 0.1mm between the 0.15mm, and utricule 1 diameter of the sacculus that all uses with routine of utricule 1 diameter of utricule 1 far-end is reference.
During use; Send into coronary dilation sacculus (meet basically vascular lesion before and after blood vessel diameter) to the vascular lesion place and implement the sacculus predilation along guiding seal wire (this seal wire has been delivered to the lesion vessels far-end) in the guiding catheter; Balloon expandable is withdrawn from the coronary dilation sacculus after accomplishing, and then sends into the support of corresponding size.
Claims (1)
1. coronary dilation sacculus; By utricule (1) partly, the proximal head (3) that is positioned at the distal head (2) of utricule (1) far-end and is positioned at utricule (1) near-end forms; It is characterized in that; Said utricule (1) is that the even cumulative amount of utricule (1) diameter is 0.1mm ~ 0.15mm in every 10mm length from the even cumulative drum of utricule (1) far-end to utricule (1) proximal diameter.
