摘要：
A device for accessing and distending a joint comprises a distraction structure having a generally tapered distal portion adapted to penetrate a tissue region and create an access space within a joint. The distraction structure also includes a lumen extending from a proximal surface to a distal portion. The device further includes a distention structure deployable through the lumen and adapted to exert a force between a first joint surface and a second joint surface and create a working space. The distention structure may, in some embodiments, include an elongate member having a proximal end, a distal end, and a lumen extending along at least a portion of the length of the elongate member, a first expandable region deployable from a first substantially collapsed position to a second substantially expanded position, the first expandable region adapted to exert a force between the first joint surface from the second joint surface.
