Abstract
The invention relates to a catheter with a strip saccule on the surface, which comprises a guide wire (11), an inner catheter (12), an outer catheter (13), a saccule body (A), strip bulges (14), concave channels (15) and a medicament coating (16), and is characterized in that: the surface of the outer catheter is provided with the saccule body formed by arranging and combining the strip bulges (14) and the concave channels (15) at intervals. The catheter with the strip saccule on the surface can carry more medicaments, ensures that the medicaments are difficult to fall off in the process of advancing, expanding and rubbing a vascular wall because the vascular wall is difficult to contact and rub the medicaments in the pits and concave channels on the surface, and can effectively improve treatment efficiency.
Description
Technical field
The present invention relates to a kind of foley's tube of face coat medicine, especially a kind of surperficial strip foley's tube 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 distal end of catheter body region, an inflatable complete sacculus body around the seal wire, smooth even curface coating medicine, play and carry or slow releasing function.In the use, the characteristics of smooth even curface caused the medication amount of coating few and also advance, expand and the process of the blood vessel wall that rubs in caducous shortcoming.
Therefore, how existing plain edition foley's tube is carried out necessary improvement, makes it can carry more medicine, and advance, expand and the process of the blood vessel wall that rubs in difficult drop-off.
Summary of the invention
Purpose of the present invention is intended to: propose a kind ofly can carry more medicine, simultaneously because of the blood vessel contact with rub off the medicine that the sacculus outer wall applies, make sacculus can advance, expand and the process of the blood vessel that rubs in difficult drop-off be coated in the foley's tube of the medicine on utricule surface.
This surperficial strip foley's tube comprises seal wire, inner catheter, outer catheter, sacculus body and medication coat, it is characterized in that: described sacculus body is the chamber type utricule that strip swells and the concavity gully combines alternately for the surface.
The strip protuberance quantity of described sacculus body is at 2 ~ 80.
Strip on described sacculus body protuberance presents and guidewire shaft strip in the same way distributes, perhaps be and the coaxial orthogonal round of guidewire shaft distributes, or the distribution of oblique strip, and assembly partly or completely.
Outer surface on the described sacculus body distributing a large amount of pits and projection.
The outer surface painting medicine or the medication coat of described sacculus body.Medicine not only is distributed in the concavity gully, also is distributed in a large amount of pits.
Each bar strip size of described sacculus can be identical, also can be different.
The outer contour of described sacculus body is shaped as spindle, elongated cylindrical, sphere or other irregular class spindles.
Described sacculus body is thin-film material, fabric material, nonwoven cloth, perhaps is the compound of above-mentioned material.
The outer surface of described sacculus body 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.
This surperficial strip foley's tube according to the technical scheme proposition, can not only carry more medicine, simultaneously again because the difficult medicine that contacts and rub off in concavity gully and the pit of blood vessel, make it possible to advance, expand and the process of the blood vessel wall that rubs in the difficult drop-off medicine, can effectively improve therapeutic efficiency.

The specific embodiment
This surperficial strip foley's tube as shown in the figure, it is to the existing percutaneous transluminal angio plasty that generally uses and the inventive improvements of percutaneous transluminal coronary angioplasty foley's tube.
This surperficial strip foley's tube comprises seal wire 11, inner catheter 12, outer catheter 13, sacculus body A, strip protuberance 14, concavity gully 15 and medication coat 16, it is characterized in that:
Described sacculus body A upper surface is the chamber type utricule that strip protuberance 14 and concavity gully 15 combine alternately.
The two ends of the sacculus body A that states are separately fixed on the outer catheter 13 that is divided into two-section.
The quantity of the strip protuberance 14 on the described sacculus body A is at 2 ~ 80.
The strip of described sacculus body A protuberance 14 and concavity gully 15 presents and 11 strips in the same way of seal wire distribute, perhaps be and the coaxial orthogonal round of guidewire shaft distributes, or the distribution of oblique strip, and assembly partly or completely.
Outer surface on the described sacculus body A distributing a large amount of pits and projection.
Strip on described sacculus body A protuberance 14 presents the assembly that the coaxial slanted bar shape with the guidewire shaft oblique distributes, and perhaps is the assembly with the coaxial cross-distribution of guidewire shaft oblique.
The outer surface painting medicine of described sacculus body A or medication coat 16; Described medication coat not only is distributed in the concavity gully, also is distributed in the pit on utricule surface.When this layout helps preventing that utricule from moving ahead in blood vessel, just break away from utricule because of friction no show area for treatment taking place with blood vessel.
Each bar strip size of described sacculus body A can be identical, also can be different.
Described sacculus body A is shaped as spindle, elongated cylindrical, sphere or other irregular class spindles.
Described sacculus body A is thin-film material, fabric material, nonwoven cloth, perhaps is the compound of above-mentioned material.
The outer surface of described sacculus body A 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.
This novel surface strip foley's tube, not only form concavity gully 15 between a large amount of pits by sacculus body A surface and the adjacent two strips protuberance 14 and carry more medicine, simultaneously again because the difficult medicine that contacts and rub off in the concavity gully 15 of blood vessel, make it possible to advance, expand and the process of the blood vessel wall that rubs in the whole medicines of difficult drop-off, therefore can effectively improve therapeutic efficiency.
In the use, according to operation plan, select suitable number and the suitable sacculus that carries drug weight, in advance behind the sacculus percutaneous intravasation destination locations of Shou Suoing, behind inflation or the topping up body, sacculus expands gradually, thereby struts the narrow blood vessel in many places, drug effect plays therapeutical effect at blood vessel, and a large amount of pits on surface and the medicine in the concavity gully 15 can continue the long period and not come off.The hydrophilic coating of sacculus outer surface helps sacculus to move swimmingly in blood vessel.
