Abstract

A fixation device comprises a first clamping member having an adjustable clamping collar and a first curved support portion attached to the adjustable clamping collar. The first clamping member is adapted to receive a digit. The first curved support portion is adapted to support an inferior surface of a proximal phalanx of the digit. A distal member is adjustably attachable to the first clamping member. The distal member has a second curved support surface adapted to support an inferior surface of a distal phalanx of the digit and a curved distal end adapted to apply a compressive force in a proximal direction to a distal end of the distal phalanx.

First claim

What is claimed is:

1. A fixation device, comprising:
a tube comprising a contractible tubular woven mesh configured to contract radially under longitudinal tension; and
at least one helical yarn or fiber fastened at or near a first end of the tube and woven helically through the mesh and extending from a second end of the tube opposite the first end of the tube, such that the yarn is capable of applying radial compression to the tube when placed under tension.

2. The fixation device of claim 1 , wherein the at least one helical yarn or fiber includes two opposing yarns or fibers extending in opposite directions around a circumference of the tube, such that the helical yarn or fiber is configured to cinch ends of the tube while applying compressive force to straighten a joint of a digit surrounded by the tube, when the helical yarn or fiber is pulled.

3. The fixation device of claim 1 , further comprising:
a plurality of sleeves arranged around an outer surface of the tube, the sleeves smaller in diameter than the tube; and
at least one rib removably insertable in at least a respective one of the plurality of sleeves, the at least one rib formed of a material that is more rigid than a material of the tubular woven mesh.
