Abstract
The invention relates to a drug eluting balloon. The drug eluting balloon comprises a balloon body, wherein the middle of the balloon body is cylindrical, the two ends of the balloon body are conical, one end of the balloon body is connected with a connecting pipe through a guide pipe, a plurality of pits are formed in the outer wall of the cylindrical middle portion of the balloon body, the elasticity modulus of each pit is smaller than the elasticity modulus of the balloon body, the elasticity modulus difference meets the conditions that the pits sink towards the interior of the balloon body when the balloon body is filled with no filing medium and the pits protrude towards the outside of the balloon body when the balloon body is filled with filling media, and by the adoption of the design, the superficial area of the balloon is increased, drug adhesion is improved, drugs are ejected in the form of a drug pill when the balloon expands, and it is guaranteed that drugs are released fully in a short time. According to the drug eluting balloon, a special structure is adopted, the drug loading capacity is improved based on a traditional drug balloon, and drugs are released fully through ejection; after the drug balloon is used, the defects of a drug support can be effectively overcome, a patient just needs to take duplex antiplatelet drugs conventionally in a short time, and the metal burden and the economical burden of the patient are greatly reduced.
Description
Technical field
The invention belongs to medicament elution technical field of tools, particularly relate to a kind of medicament elution sacculus.
Background technology
Over nearly 10 years, along with the appearance of bracket for eluting medicament, solve the problem of most sufferer clinically.But the formation of advanced thrombus and in-stent restenosis, slow-release medicine coating bracket makes endothelium healing time extend, comparatively limit to the process of Small vessel and bifurcation lesions and problem that Post operation need take the aspects such as duplex antiplatelet drug 1 year also seriously governs the clinical Benefit degree of bracket for eluting medicament.The appearance of medicinal balloon, successfully overcomes these defects of drug stent.Further, after drug application sacculus, patient only needs short time routine to take duplex antiplatelet drug, and this also significantly reduces the financial burden of patient.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of newtype drug eluting sacculus, amass by increasing balloon surface, strengthen medicine adhesive force, and by effect that medicine bullet formula is launched in balloon expandable process, guarantee medicine abundant release at short notice, and patient is after this sacculus of application, only need short time routine to take duplex antiplatelet drug, significantly reduce patient mental and material burden.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of medicament elution sacculus, comprise balloon body, cylindrical in the middle part of described balloon body, two ends coning, described balloon body one end is connected with connection tube by conduit, with some depressions on the outer wall of described balloon body cylindrical central part, the elastic modelling quantity of described depression is less than the elastic modelling quantity of balloon body, the elastic modulus difference of described depression and balloon body, when balloon body is not filled with filled media, described depression is to balloon body sunken inside, when balloon body is full of, described depression is protruded outside balloon body.
This special tectonic can add balloon surface and amass, and strengthens medicine adhesive force, and medicine bullet formula is launched in balloon expandable process, guarantee medicine abundant release at short notice.
What described balloon body adopted is quick seal wire switch mode.
Described conduit is bimetallic tube, and one deck of described bimetallic tube is communicated with balloon body and is connected contrast agent by connection tube, and another layer of described bimetallic tube is through balloon body two ends, for penetrating seal wire.
Described being recessed on balloon body outer wall is provided with some layers vertically, and every layer of depression is evenly arranged around balloon body axis.
Beneficial effect
The present invention adopts special tectonic, the basis of conventional medicament sacculus adds drug loading, and fully discharges medicine by ejection mode.Patient, after drug application sacculus, effectively can overcome the defect of drug stent, only needs short time routine to take duplex antiplatelet drug, significantly reduces patient mental and material burden.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figures 1 to 4, a kind of medicament elution sacculus, comprise balloon body 2, cylindrical in the middle part of described balloon body 2, two ends coning, described balloon body 2 one end is connected with connection tube 1 by conduit 3, with some depressions 4 on the outer wall of described balloon body 2 cylindrical central part, the elastic modelling quantity of described depression 4 is less than the elastic modelling quantity of balloon body 2, the elastic modulus difference of described depression 4 and balloon body 2, when balloon body 2 is not filled with filled media, described depression 4 is to balloon body 2 sunken inside, when balloon body 2 is full of, described depression 4 is protruded outside balloon body 2.
Which increase balloon surface to amass, strengthen medicine adhesive force, and by the effect that medicine bullet formula is launched in balloon expandable process, guarantee medicine abundant release at short notice.
What described balloon body 2 adopted is quick seal wire switch mode.
Described conduit 3 is bimetallic tube, and one deck of described bimetallic tube is communicated with balloon body 2 and is connected contrast agent by connection tube 1, and another layer of described bimetallic tube is through balloon body 2 two ends, for penetrating seal wire.
Described depression 4 is provided with some layers vertically on balloon body 2 outer wall, and every layer of depression 4 is evenly arranged around balloon body 2 axis.
In actual use, the medicine that medicinal balloon carries is recessed in balloon body 2 by depression 4, relative patient carries out coronary angiography, after confirming to need to carry out the coronary artery of medicinal balloon process, common sacculus is used to carry out predilation in lesion, after satisfied to vasodilation, medicinal balloon is inserted this Coronary Artery Lesions place, confirm location under DSA after, use the abundant dilator sacculus of compression pump, while balloon expandable, because balloon interior pressure increases, the depression 4 of medicinal balloon is fully expanded, medicine can be launched away, thus reach the effect of fully release medicine, reduce the loss of medicine, increase therapeutic effect.
