  • Patent number: 6500146
    Abstract: Dilatation balloons and catheters including same are provided. The balloons are fabricated of a material such as a nylon or a polyamide material, and they have an inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatation or the like up to a maximum pre-bursting pressure application. The maximum pre-bursting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-bursting sizes.

  • Patent number: 5342305
    Abstract: The variable distention angioplasty balloon assembly, for insertion into a blood vessel, comprises an inner elongated, inflatable balloon having a distal portion, a proximal portion and an intermediate portion therebetween and defining therein a first chamber. The inner balloon has a first Young's modulus. The outer elongated, inflatable balloon has a distal portion, a proximal portion and an intermediate portion therebetween positioned around the inner balloon and defines between the balloons a second chamber. The outer balloon has a second Young's modulus. The inner balloon is substantially enclosed by the outer balloon, and the first Young's modulus of the inner balloon is less than the second Young's modulus of the outer balloon. The first chamber of the inner balloon and the second chamber of the outer balloon define a variable dilation structure for dilating an anatomical stricture.

  • Patent number: 4699157
    Abstract: A pacing catheter having improved torque control properties, including a polymeric tube having an electrically conductive torque member passing through the tube center. The torque member is tapered near the distal end where it is secured to a cup-shaped electrode adapted to fit over the distal end of the polymeric tube. The space between the polymeric tube and the torque member is filled with a polymeric or elastomeric material in fluid form such that a solid, but flexible, polymeric composition is formed which adheres to both the inside of the polymeric tube and the outside of the torque member. The solidified liquid polymeric material allows rotation force applied anywhere along the hollow outer tube to be directly transmitted to the central torque member.
