Abstract
The invention relates to a novel muti-segment balloon dilatation catheter. The balloon dilatation catheter comprises a guide wire (1), an internal catheter (2), an outer catheter (3), balloon bodies (4) and developing rings (5), and is characterized in that the outer catheter (3) is equipped with a plurality of segments of the balloon bodies (4) which are coaxial with the guide wire (1); and the dilatated balloon bodies (4) are arranged according to the diameter from small to large size or from large to small size. By utilizing the diameter-graded muti-segment balloon dilatation catheter, a plurality of narrow blood vessels in the same blood vessel can be opened at the same time, and the balloon dilatation catheter has the characteristic of gradual change of diameter based on gradual change of inner diameter of the vessels, thus reducing discomfort feeling of a patient caused by a plurality of insertion of the catheter with single balloon; and meanwhile administration can be carried out at the same time, thus effectively improving the treatment efficiency.
Description
Technical field
The present invention relates to a kind of foley's tube, especially a kind of novel multisection type expansion of balloon catheter is applicable to the usefulness of percutaneous transluminal angio plasty and percutaneous transluminal coronary angioplasty.
Background technology
Foley's tube is a kind of instrument that is used for blood vessel internal shaping art, has been widely used in the clinical medicine of percutaneous transluminal angio plasty and percutaneous transluminal coronary angioplasty.It is under the guiding of medical imaging device, foley's tube is inserted the narrow positions of blood vessel with the percutaneous puncture technology, under proper intensive care, carry out balloon expandable and expand, make the narrow positions of blood vessel obtain expansion, thereby reach the purpose of recovering lumen diameter, accelerating blood circulation.Existing sacculus body all is arranged on the distal end of catheter body region, centers on a seal wire inflatable complete sacculus body on every side.In the use, when this sacculus body in human lesion vascular site migration process, in case when advancing to vascular site, because whole conduit is in case of bending with certain camber, since long with the distance that blood vessel touches, therefore can make the impelling ratio of conduit difficult.In addition, in case when patient's angiostenosis was between a few sections adjacent regions of same blood vessel, the foley's tube that generally uses can't disposablely be finished dilation therapy now, must repeatedly carry out this expansion operation.Obviously can bring more mental pressure and misery to the patient.
Therefore, how existing plain edition foley's tube is carried out necessary improvement, it can disposablely be expanded being positioned at same endovascular multistage narrow blood vessel simultaneously, and select suitable multisection type sacculus for use according to the prescription before the art, can help foley's tube in blood vessel, to realize the usefulness of fast moving again simultaneously because of gradual change internal diameter blood vessel gradual change diameter.
Summary of the invention
Purpose of the present invention is intended to: propose a kind of can either the expansion simultaneously being positioned at same endovascular multistage narrow blood vessel with a ball ductus bursae is disposable, and select the suitable multisection type sacculus because of gradual change internal diameter blood vessel gradual change diameter for use according to the prescription before the art.
This novel multisection type expansion of balloon catheter, comprise seal wire, inner catheter, outer catheter, sacculus and development ring, it is characterized in that: the utricule diameter after its expansion of the co-axial utricule of multistage that is provided with on the described outer catheter and seal wire is ascending, and perhaps descending state is arranged.
The quantity of described sacculus is at 1 ~ 10 section.
Described sacculus be shaped as spindle, elongated cylindrical, sphere or other irregular class spindles.
Described sacculus is thin-film material, fabric material, nonwoven cloth, perhaps is the compound of above-mentioned material.
The outer surface of described sacculus is decorated with hydrophilic coating, and described hydrophilic coating is a kind of in polyvinylpyrrolidone, polyethylene glycol oxide, Polyethylene Glycol, polypropylene glycol, polyacrylamide, the polyacrylic acid or their complex.
The outer surface of described sacculus is provided with medicine or medication coat.
This Diameter Gradual Change multisection type expansion of balloon catheter according to the technical scheme proposition, can not only snugly strut same blood vessel different inner diameters place simultaneously and have the narrow blood vessel in many places, reduce patient and use the discomfort sensation of having only repeatedly inserting of single foley's tube existence and bringing, and administration simultaneously, can effectively improve therapeutic efficiency.

The specific embodiment
The novel multisection type expansion of balloon catheter of this Diameter Gradual Change shown in Fig. 1 or 3, it is to the existing percutaneous transluminal angio plasty that generally uses and the inventive improvements of percutaneous transluminal coronary angioplasty foley's tube, and emphasis has considered that the internal diameter of blood vessel is the feature that gradual change changes.
The novel multisection type expansion of balloon catheter of this Diameter Gradual Change, comprise seal wire 1, inner catheter 2, outer catheter 3, sacculus body 4 and the ring 5 that develops, it is characterized in that: the multistage and the co-axial sacculus body 4 of seal wire that are provided with on the described outer catheter 3, sacculus body 4 diameters after it expands are ascending, and perhaps descending state is arranged.
Just diameter after the expansion of described sacculus body 4 is designed to gradual change, the 1st section sacculus be than the 2nd section, and the 3rd section ..., the n section, more and more thinner, perhaps more and more thicker; Also comprise irregular gradual change.When the one-part form gradual change sacculus that adopts as shown in Figure 1, the utricule diameter of two ends one end of the sacculus body 4 of this foley's tube is than the utricule slightly larger in diameter of the other end.
The quantity of described sacculus body 4 is at 1 ~ 10 section.
Described sacculus body 4 be shaped as spindle, elongated cylindrical, sphere or other irregular class spindle.
Described sacculus body 4 is thin-film material, fabric material, nonwoven cloth, perhaps is the compound of above-mentioned material.
The outer surface of described sacculus body 4 is decorated with hydrophilic coating, and described hydrophilic coating is a kind of in polyvinylpyrrolidone, polyethylene glycol oxide, Polyethylene Glycol, polypropylene glycol, polyacrylamide, the polyacrylic acid or their complex.
The outer surface of described sacculus 4 is provided with medicine or medication coat.
The percutaneous transluminal angio plasty sacculus of this novel Diameter Gradual Change multisection type and percutaneous transluminal coronary angioplasty sacculus, not only snugly struts the narrow blood vessel in many places simultaneously, and can also administration.
In order to solve the problems of the technologies described above, the percutaneous transluminal angio plasty sacculus of this novel Diameter Gradual Change multisection type and percutaneous transluminal coronary angioplasty sacculus are made of the sacculus of seal wire, conduit and face coat, and the sacculus of face coat scribbles hydrophilic and medicine.According to operation plan, select the sacculus of suitable hop count and suitable interval, and the external diameter thickness meets the characteristics of blood vessel thickness fully, in advance behind the sacculus percutaneous intravasation destination locations of Shou Suoing, behind inflation or the topping up body, every section sacculus of Diameter Gradual Change expands gradually, thereby snugly struts the narrow blood vessel in many places, and drug effect plays therapeutical effect at blood vessel.The hydrophilic coating of sacculus outer surface helps sacculus to move swimmingly in blood vessel.
