摘要:
Devices and methods are disclosed for providing access to a central compartment of a hip joint. The devices can access the central compartment by distracting all or a portion of the labrum. The labrum can be distracted by advancing a device underneath the bottom edge of the labrum, and using the device to further distract the labrum. Some devices can move underneath the labrum to provide a gap for other devices to access the central compartment.

摘要:
A method for creating space in a joint, the method comprising: applying force to a body part so as to distract the joint and create an intrajoint space; inserting an expandable member into the intrajoint space while the expandable member is in a contracted condition; expanding the expandable member within the intrajoint space; and reducing the force applied to the body part so that the joint is supported on the expandable member.

A joint-spacing balloon catheter comprising: a shaft having a distal end and a proximal end; first and second balloons mounted to the distal end of the shaft, the first balloon being disposed distal to, and spaced from, the second balloon, with the portion of the shaft between the first and second balloons being flexible; and a handle attached to the proximal end of the shaft.
