    Abstract: Flexible high-pressure angioplasty balloons are disclosed herein which utilize an inflatable balloon positioned upon the catheter and a supporting structure secured over or along the catheter at a first location proximal to the balloon and at a second location distal to the balloon. Inflation of the balloon reconfigures the supporting structure to urge the first location and the second location towards one another thereby inhibiting longitudinal elongation of the balloon relative to the catheter. The supporting structure may surround, support, or otherwise extend over the entire length of the balloon and allows for the balloon to retain increased flexibility which enables the balloon to bend or curve even at relatively high inflation pressures.

  • Patent number: 8840743
    Abstract: Method for fabricating a balloon catheter including providing an inner tubular member having a distal section and a distal end with a lumen extending therein and forming a balloon having a distal leg with a first segment having a first diameter and a first wall thickness and a second segment having a second wall thickness. The second diameter is greater than the first diameter and the first wall thickness is greater than the second wall thickness. The distal end section of the inner tubular member can be positioned in the balloon and bonded to the first segment while reducing the diameter of the second segment. Method also provided for fabricating a multilayer balloon catheter including removing at least a portion of an outer layer from the distal leg of the balloon.

  • Publication number: 20140276406
    Abstract: The present disclosure is directed toward a semi-compliant to non-compliant, conformable balloon useful in medical applications. Conformable balloons of the present disclosure exhibit a low or insignificant straightening force when in a curved configuration and at inflation pressures greater than 4 atm. Balloons of the present disclosure are constructed of material that can compress along an inner length when the balloon is in a curved configuration. In further embodiments, balloons of the present disclosure can be constructed of material that sufficiently elongates along an outer arc when the balloon is in a curved configuration. As a result, medical balloons, in accordance with the present disclosure, when inflated in a curved configuration, exhibit kink-free configurations and do not cause a significant degree of vessel straightening.

  • Patent number: 8834414
    Abstract: This invention relates to a method that comprises the introduction of a catheter via left subclavian vein, advancing into the right atrium and then positioning it in the inferior vena cava, just at the cava-diaphragm junction, where it is anchored at its extreme; and thereafter an external inflation of a balloon positioned in said catheter takes place through a physiological solution to reach a diameter corresponding to half the diameter of the inferior vena cava, resulting in hemi-occlusion in the expiration phase (breath-out) and total occlusion for a short period during the inspiration phase (breath-in), regulating (normalizing) the venous return and decreasing the cardiac volume overload, as a treatment for heart failure. The invention also comprises hydromechanics devices to normalize the venous return in the circulatory system. Said venous return is increased in 90% of patients with heart failure.

  • Patent number: 8784470
    Abstract: The invention relates to a balloon catheter comprising a catheter tube, an inflatable balloon, the ends of which are attached to the catheter tube, and a stent attached around the balloon. The stent extends at least partly along the length of the balloon. In an uninflated state, at least the outside surface of the balloon not covered by the stent is provided with a relief structure which is substantially disappeared in an inflated state of the balloon. The invention also relates to a method for manufacturing such a balloon catheter.

  • Patent number: 8764705
    Abstract: A balloon and method of making a balloon catheter is provided. The balloon for the balloon catheter may be made by slicing through an integral dilation element on a parison (10). The parison may then be stretched to spread the slices to form wider gaps (20). The gaps define separate dilation element segments (14), which may make the balloon more flexible.

  • Patent number: 8747353
    Abstract: A method for manufacturing a balloon catheter assembly includes forming a balloon from a polymer selected from the group consisting of polyamide, polyether block amide, and polyethylene terephthalate, forming a plurality of pores in the polymer, and mounting the balloon onto a catheter shaft. The shaft is configured to supply a fluid to the balloon to inflate the balloon, and the pores are configured to prevent the fluid from passing through the balloon.

  • Patent number: 8721590
    Abstract: A device for interventional surgical or medical procedures is presented. The device is generally in the form of a balloon and is used to position itself or other working elements up against or through lumen walls in the body. The balloon is comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. The elastomeric component is fixedly attached to the flexible but relatively non-distensible component and together they form a pressure vessel that can be inflated within the lumens of the body.

  • Patent number: 8715229
    Abstract: A non-compliant medical balloon comprises a base balloon including a pair of spaced-apart, generally conical end sections and a generally cylindrical center section connected therebetween. A braided fabric sleeve surrounds at least a portion of the base balloon, wherein the sleeve is formed of at least three substantially inelastic fibers intertwined in such a way that no two of the three fibers are twisted exclusively around one another. The sleeve is permanently affixed to the outer surface of the base balloon so as to prevent excessive expansion of the base balloon when the base balloon is internally pressurized.
