  • Patent number: 10470754
    Abstract: A method of treating a patient's joint having opposing joint surfaces includes providing an elongate member having a proximal end, a distal end and an expandable member near the distal end. The expandable member is positioned in the joint between the joint surfaces and expanded so as to separate the joint surfaces away from one another into a distracted position. The joint is manipulated while in the distracted position so that the joint is distracted and in flexion. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.

  • 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.
