  • Patent number: 9669194
    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: 8986339
    Abstract: A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.

  • Patent number: 8414528
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath pair is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath pair is removed by a health professional before placing the scaffold within the body.

  • Patent number: 8388573
    Abstract: A catheter configured for delivering an agent to a patient's vessel wall is described. The catheter includes an inflatable balloon substantially covered by a expandable cage such that when the inflatable balloon is inflated the expandable cage substantially surrounds an outer surface of the inflated balloon. The inflatable balloon is configured to be deployed within a lumen against a lumen wall and separated from the lumen wall by the expandable cage in an expanded state, and is adapted to provide an agent delivery to a treatment site, and the expandable cage is further collapsible and is removable from said lumen.

  • Publication number: 20130035638
    Abstract: An angioplasty assembly having a guidewire device for use in peripheral vascular and coronary angioplasty applications. The guidewire invention has one or more angioplasty devices mounted directly on the distal tip of the guidewire. In one embodiment the angioplasty device includes an angioplasty balloon. In another embodiment, the device includes a stent balloon with expandable stent, or a self-expanding stent, or combinations of these. Preferably, the guidewire is housed within a hypotube. Optionally, the hypotube may house a retractable piercing element with a distal loop 3 suitable for piercing a vessel wall. The guidewire allows an angioplasty procedure to be completed using a single device.
