Abstract

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.

Dependent claims

A medical instrument for distending a joint, the joint including a first joint surface and a second joint surface, the medical instrument comprising:

a tubular member having a proximal end and a distal end;
a lumen extending through the tubular member between the proximal and distal ends of the tubular member;
a distal opening of the lumen at the distal end the tubular member;
a proximal opening of the lumen at the proximal end of the tubular member;
at least one expandable unit in fluid communication with the distal opening such that the distal opening of the lumen fluidly communicates with the interior of the at least one expandable unit;
a tapered distal structure extending from the distal end of the tubular member, the tapered distal structure configured for penetrating capsular tissue;
a fluid movement device attachable to the proximal end of the lumen capable of establishing a fluid connection between the fluid movement device and the proximal opening of the lumen, and capable of establishing a fluid connection between the fluid movement device and the interior of the at least one expandable unit by fluid flow through the lumen and into the interior of the at least one expandable unit;
and
a handle attachable to the tubular member.
