Definitions

  • the present invention relates to the angioplasty techniques as well as to tests on arteries having narrowed or occluded portions and more particularly to a device and a method to do arteriographies and angioplasties avoiding the injection of a contrasting medium in the vessel lumen. DESCRIPTION OF THE RELATED ART
  • Stenosis and artery blockage decrease the nourishing flow that reaches the tissues irrigated by the affected artery.
  • Tissue disorder caused by a decrease in irrigation may vary from necrosis of tissue to functional disorders caused by the decrease in the said flow.
  • secondary arteries balance the blockage of the main artery. Whenever the narrowing of the artery is treated due to the consequences of flow decrease, it should be decided whether to resort to surgery or to the dilation of the artery by making use of a balloon.
  • FIG. 1 is a side view including a detail of the cross-sectional view of a catheter in accordance with the device of the present invention
  • FIG. 1A is a cross-sectional view taken along line 1 A-1A of FIG. 1
  • FIG. 2 is a view similar to FIG. 1 of another embodiment of the device of the present invention
  • FIG. 2A is a cross-sectional view taken along line 2A-2A of FIG. 2
  • FIG. 3 is a view similar to FIG. 1 of another embodiment of the device of the present invention
  • FIG. 1 is a side view including a detail of the cross-sectional view of a catheter in accordance with the device of the present invention
  • FIG. 1A is a cross-sectional view taken along line 1 A-1A of FIG. 1
  • FIG. 2 is a view similar to FIG. 1 of another embodiment of the device of the present invention
  • FIG. 2A is a cross-sectional view taken along line 2A-2A of FIG. 2
  • FIG. 3 is a view similar to FIG. 1
  • FIG. 3 A is a cross-sectional view taken along line 3A-3A of FIG. 3;
  • FIG. 4 is a view similar to FIG. 1 of another embodiment of the device of the present invention;
  • FIG. 4A is a cross-sectional view taken along line 4A-4A of FIG. 4; and,
  • FIGS. 5 to 8 show the stages of a preferred embodiment of the present invention.
  • a catheter 1 is provided, the cross-sectional view of which in detail shows a first passage 2 that allows a guide wire 4 to run along the shaft 5 of the catheter, also providing a second passage 3 whereby the first elastomeric, thin walled and resistant, low profile diagnosis balloon 6 is inflated.
  • the material used for the said balloon may be latex, silicone, polyurethane or any other appropriate and elastomeric material whatsoever.
  • the guide wire 4 as well as the balloon 6 may be operated via operation means 7 and 8.
  • the balloon 6 is carried up to the narrowed portion of the artery, as detailed when referring to FIGS. 5 to 8, and filled with an appropriate contrast media, such as a radiopaque substance.
  • the balloon has a very thin but resistant wall, which, upon inflation, takes exactly the same form of the artery inner surface (luminogram) without deforming same.
  • the balloon 6 shall have the length required to view the desired portion of the artery.
  • the balloon may be inflated at a very low pressure thus not altering, as stated above, the contour of the artery under study.
  • This device allows a guide wire to run along the artery lumen. Owing to the fact that the balloon has a very low profile, same allows for the introduction thereof in the narrowed or occluded portion of the artery, which portion is crossed over by the guide wire.
  • the balloon 6 may be inflated at pressure of 1 to 3 atmospheres, and preferably at a pressure of approximately 2 atmospheres.
  • Diagnosis balloon 6, as previously described, can be formed of a variety of elastomeric materials such as silicone, latex, or polyurethane.
  • the elastomeric materials from which the diagnosis balloon 6 may be made are preferably ultra compliant, whereby they are capable of stretching, or expanding, up to more than 500% from their relaxed, or unstretched, state.
  • These diagnosis balloons 6, when inflated, as previously discussed, are capable of copying, or conforming to, the shape of the vessel, or artery, interior, without expanding or distending the artery, or vessel, itself.
  • the material from which the diagnosis balloon is made has an elongation property (percentage), before breaking, of from approximately 500% to 2,000% and preferably within the range of from approximately 800% to 1200%.
  • Examples of a suitable material for the manufacture of the diagnosis balloons are silicone elastomers, such as models MED-4120 and MED-4020, of NuSil Technology of Carpinteria, California. These elastomers have elongation properties of 1100% and 1000%.
  • dilation of the narrowing may then proceed by using a second expanding balloon located upon the catheter that carries the diagnosis balloon, as shown in the three embodiments of the present invention illustrated in FIGS. 2, 3, and 4.
  • the catheter la in FIG. 2 has a first passage 9 for the guide wire 4a to run, a second passage 10 that allows inflation of the diagnosis balloon 6a, similar to balloon 6 in FIG.
  • Catheter lb in FIG. 3 includes a first passage 13 for the guide wire 4b to run and a second passage 14 which allows the diagnosis balloon 6b to be inflated, which balloon is similar to balloons 6 and 6a; said catheter also includes a container that shelters a therapeutic or angioplasty balloon 12'.
  • the diagnosis balloon 6b carries the therapeutic balloon 12' within its lumen.
  • the therapeutic balloon 12' runs on the wire 4b and provides consistency to the diagnosis balloon 6b.
  • Catheter lc illustrated in FIG. 4 is similar to the one depicted in FIG.
  • the second balloons 12, 12' and 12" of the different embodiments of the present invention differ from diagnosis balloons 6 to 6c in that the former are not elastomeric for the purpose of achieving a great radial force allowing for the dilation of the narrowed artery.
  • the angioplasty balloon shall have a low profile and shall be inflated through an independent passage of the catheter, as illustrated in the case of the three passages of the pertinent embodiments.
  • diagnosis balloons 6, 6a, 6b, and/or 6c may be coated or doped with a radiopaque substance, such as barium, gold, platinum, or silver.
  • such a radiopaque substance may be mixed into the elastomeric material from which the diagnosis balloons are made.
  • the diagnosis balloons would thus be radiopaque, whereby the diagnosis balloon would not need to be expanded by the introduction of a contrast substance, but could rather be expanded with a non-radiopaque fluid, such as non-toxic gases, such as carbon dioxide, or by liquids such as water or other non-toxic liquid mixtures.
  • a radiopaque diagnosis balloon could be utilized in conjunction with an angioplasty balloon such as angioplasty balloons 12, 12' and/or 12", as previously described.
  • radiopaque diagnosis balloons may be inflated to conform to vessel, or artery, irregularities and narrowing. It is believed that a radiopaque diagnosis balloon will be useful in imaging ostial lesions, where a large vessel has branches, and where stenosis can occur at the junction of two vessels. Again, as with a diagnosis balloon filled with a contrast material, there is a significant clinical advantage since toxic radiopaque contrast media need not come into contact with living tissue. As regards another aspect of the present invention, a method is illustrated in FIGS.
  • the artery is punctured and a guide wire is introduced which crosses over narrowing or occlusion "E", as illustrated in FIG. 5.
  • This step is similar to any other angiographic procedure which may include angioplasty or not.
  • an introducer means of a suitable size is placed to allow the introduction of a diagnosis-therapeutic catheter.
  • the device is moved forward until the narrowing "E” is crossed over, placing the diagnosis balloon of the present invention all along the artery under study, as illustrated in FIG. 6.
  • the diagnosis balloon is filled with a contrasting substance at a very low pressure and the balloon is kept dilated.
  • the angiographic tests are accurately done and the catheter is placed in the right angle and location so as to achieve a better view of the narrowed portion of the artery.
  • the elastomeric balloon is deflated and the angioplasty balloon 12 is placed at the narrowing "E" level. Then, same is inflated for the purpose of dilating the injured portion of the artery.
  • the angioplasty balloon is deflated and the diagnosis elastomeric balloon is affixed in the right position, repeating the diagnosis steps for the purpose of confirming the effectiveness of the artery dilation attained. Should dilation be suitable, the proceeding shall be deemed to be finished; should dilation fail to be suitable, the proceeding shall be repeated.
  • a balloon having a different diameter may be affixed avoiding the initial system; a "stent" may alternatively be attached.
  • the very same non-elastomeric balloon that comprises the device may be used or else, another balloon with different features may be employed.
  • diagnosis balloons 6, 6a, 6b, and/or 6c have been made radiopaque, as previously described, the foregoing described method may also be conducted in the same manner, except that it would not be necessary to fill the radiopaque diagnosis balloon with a contrast substance.
  • the radiopaque balloon could be filled with a contrast substance at a very low pressure.
  • the angioplasty may be done without changing the device and an x-ray check-up may be done simultaneously as by inflating the elastomeric balloon again in order to confirm the effectiveness of the dilation as regards reduction of artery narrowing.
  • This procedure proves to be cost efficient since the amount of contrasting substance injected as well as the time consumed are reduced.
  • the contrast media is not injected directly into the artery, substances utilized do not need to be non-ionic. Both quality and volume of contrast media can be a source of decreasing costs in addition to the advantages enumerated in relation to decreasing risks to the patient.
