Abstract

An orthopedic device includes a posterior shell with ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect of the posterior shell. A dorsal shell is contoured to substantially correspond to the opening of the posterior shell. The dorsal shell includes a proximal member and a distal member hingedly connected to the proximal member via a hinge mechanism. A pump assembly receiving opening is defined in the proximal member of the dorsal shell and a raised portion extends longitudinally along an exterior surface of the dorsal shell. A plurality of clearance holes are defined in the first and second wing portions. An inflatable bladder is disposed at least in the ankle receiving portion of the posterior shell. A pump assembly is inserted through the pump assembly receiving opening and is in fluid communication with the inflatable bladder.

First claim

The invention claimed is:

1. An orthopedic device, comprising:
a posterior shell having ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to substantially correspond to the opening of the posterior shell, the dorsal shell including a proximal member and a distal member hingedly connected to the proximal member via a hinge mechanism;
a pump assembly receiving opening defined in the proximal member of the dorsal shell;
a raised portion formed in a single piece with the dorsal shell and extending longitudinally along an exterior surface of the dorsal shell;
a plurality of clearance holes defined in the first and second wing portions of the posterior shell;
an inflatable bladder disposed in at least the ankle receiving portion of the posterior shell; and
a pump assembly inserted through the pump assembly receiving opening, and in fluid communication with the inflatable bladder.

2. The orthopedic device of claim 1 , further comprising a plurality of clearance holes defined in the proximal and distal members of the dorsal shell.

3. The orthopedic device of claim 2 , wherein a first portion of the plurality of clearance holes in the dorsal shell are defined in the raised portion.

4. The orthopedic device of claim 3 , wherein a second portion of the plurality of clearance holes extend radially outward relative to the raised portion.

5. The orthopedic device of claim 1 , wherein the pump assembly receiving hole includes a tapered ridge extending around a periphery thereof.

6. The orthopedic device of claim 2 , wherein the pump assembly comprises a flexible bulb-shaped pump.

7. The orthopedic device of claim 1 , wherein the pump assembly receiving hole is defined in the raised portion.

8. The orthopedic device of claim 1 , further comprising a pressure relief valve located on the proximal member of the dorsal shell, and in fluid communication with the inflatable bladder.

9. The orthopedic device of claim 1 , wherein the inflatable bladder includes medial and lateral bladders.

10. The orthopedic device of claim 1 , wherein the inflatable bladder is disposed in a liner.

11. The orthopedic device of claim 1 , wherein the first and second wing portions define a pair of elongate slots extending longitudinally along a length of the posterior shell.

12. The orthopedic device of claim 1 , wherein the hinge mechanism comprises a pivot pin.

13. An orthopedic device, comprising:
a posterior shell having ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect thereof;
a plurality of clearance holes defined in the first and second wing portions of the posterior shell;
a dorsal shell contoured to substantially correspond to the opening of the posterior shell, the dorsal shell including a proximal member and a distal member hingedly connected to the proximal member;
a pump assembly receiving opening defined in the proximal member of the dorsal shell, and arranged to receive a pump assembly; and
a raised portion formed in a single piece with the dorsal shell and extending longitudinally along an exterior surface of the dorsal shell.

14. The orthopedic device of claim 13 , further comprising:
an inflatable bladder situated in at least the ankle receiving portion of the posterior shell; and
a pump assembly inserted through the pump assembly receiving opening, and in fluid communication with the inflatable bladder.

15. The orthopedic device of claim 14 , further comprising a liner disposed in the ankle and foot receiving portions of the posterior shell.

16. The orthopedic device of claim 15 , wherein the inflatable bladder is disposed within the liner.

17. The orthopedic device of claim 14 , wherein the pump assembly comprises a flexible bulb-shaped pump.

18. The orthopedic device of claim 13 , wherein the pump assembly receiving hole is defined in the raised portion.

19. An orthopedic device, comprising:
a posterior shell having ankle and foot receiving portions, and first and second wing portions forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to substantially correspond to the opening of the posterior shell, the dorsal shell including a proximal member and a distal member hingedly connected to the proximal member via a hinge mechanism;
a pump assembly receiving opening defined in the proximal member of the dorsal shell, the pump assembly receiving hole having a tapered ridge extending around a periphery thereof;
a plurality of clearance holes defined in the first and second wing portions of the posterior shell;
a raised portion formed in a single piece with the dorsal shell and extending longitudinally along an exterior surface of the dorsal shell;
an inflatable bladder disposed in at least the ankle receiving portion of the posterior shell; and
a pump assembly including a flexible bulb pump inserted through the pump assembly receiving opening, the pump assembly in fluid communication with the inflatable bladder.

20. The orthopedic device of claim 19 , wherein the raised portion has a varying lateral dimension.
