  • Patent number: 10426453
    Abstract: A method for creating space in a joint formed at the convergence of two bones, the method comprising: applying force to a body part so as to separate the two bones from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state, whereby to distract the joint and create an intrajoint space; inserting an assembly of three balloons into the intrajoint space while the assembly of three balloons is in a contracted condition; expanding the assembly of three balloons within the intrajoint space; and reducing the force applied to the body part so that the joint is supported on the assembly of three balloons, with the two bones remaining separated from one another by a distance which is greater than the distance that they are normally separated from one another when the joint is in a healthy state.

An exterior surface of the inner tubular member defines a fluid flow port in fluid communication with the fluid lumen and located along a region of the inner tubular member. Catheter further includes an outer member having a distal section movable relative to the inner tubular member and having an interior surface. A piston balloon is coupled to the inner tubular member distal to the fluid flow port and is in fluid communication with the inflation lumen. A pressure chamber is in fluid communication with the fluid flow port. Fluid introduced through the inflation lumen inflates the piston balloon to seal against the interior surface and fluid introduced through the fluid flow port and into the pressure chamber applies a force to urge at least the distal section of the outer member in a proximal direction.

  • Patent number: 8486011
    Abstract: A balloon of a balloon catheter is inflated with a liquid inflating medium by a syringe through a flow line. Air in the flow line and the balloon is displaced into a return line. The balloon is deflated by drawing the liquid inflating medium from the balloon along with the air in the return line into the syringe where the air is trapped in the syringe. The balloon is reinflated and deflated by the syringe until the level of air in the liquid inflating medium has been reduced to a predefined level. A first non-return valve and a second non-return valve are provided in the flow and return lines, so that the liquid inflating medium is prevented from flowing from the balloon to the syringe in the flow line and from the syringe to the balloon in the return line.

  • Patent number: 8463359
    Abstract: An expandable member for characterizing a three-dimensional space within a mammalian body is described. The expandable member is delivered to a target region in a deflated state where it is expanded by inflation of the member. Sensory transducers that contact the member relay sensory information generated when the member is in an expanded state to a microprocessor located outside the body. Using the sensory information, a data-driven picture that characterizes the three-dimensional space within the body is created with a microprocessor. The apparatus is useful in preparation for minimally invasive surgical therapy.
