Abstract

A moldable ankle flexible brace is disclosed. The flexible ankle brace may include a heat-moldable, multi-layer leg support portion, a heat-moldable, multi-layer foot support portion, a pair of hinges connecting the leg support portion to the foot support portion, an opening for receiving a user's ankle, and a closure mechanism. The flexible ankle brace may include a middle layer that is substantially stiff at a temperature below about 130° F. and moldable at temperatures above 130° F. Also disclosed is a method of using a flexible ankle brace to treat an ankle. The method may include, for example, heating the brace to above 130° F. placing the heated brace on a patient's ankle and molding the brace to conform to the shape of the patient's ankle.

First claim

What is claimed is:

1. A flexible stabilizing ankle brace, comprising:
a heat-moldable, multi-layer leg support portion, the leg support portion comprising a tibial cuff and a selectively removable fibial cuff, wherein removal of the selectively removable fibial cuff forms an opening on a posterior of the heat-moldable, multilayer leg support portion for receiving a user's leg;
a heat-moldable, multi-layer foot support portion;
a pair of hinges connecting said tibial cuff of said leg support portion to said foot support portion; and
a closure mechanism configured to be positioned over the opening.

2. The brace of claim 1 , wherein said multi-layer leg support portion and said multi-layer foot support portion each comprise a middle layer, wherein said middle layer is substantially stiff at a temperature below about 130° F. and moldable at temperatures between about 130° F. and 220° F.

3. The brace of claim 2 , wherein said multi-layer leg support portion and said multi-layer foot support portion each further comprise an outer layer, said outer layer comprising a fabric selected from the group consisting of knit nylon spandex blend, knit polyester spandex blend, fabrics of nylon, polyester, lycra, and rubberized materials.

4. The brace of claim 3 , wherein said multi-layer leg support portion and said multi-layer foot support portion each further comprise an inner layer selected from the group consisting of a closed cell foam layer, an open cell foam layer, a gel layer, a soft polymer layer, an insulating fabric, a multilayer or lofted insulating fabric, and combinations thereof.

5. The brace of claim 4 , wherein said inner layer further comprises a chemical additive selected from the group consisting of an antimicrobial, skin lotion, and topical therapeutic agent.

6. The brace of claim 4 , wherein at least one of the pair of hinges comprises an elastomeric portion configured to provide the motion of the hinge.

7. The brace of claim 4 , wherein at least one of the pair of hinges comprises a locking mechanism configured to selectively couple with a body of the hinge, wherein the locking mechanism is configured to limit the motion of hinge when the locking mechanism is selectively coupled to the body of the hinge.

8. The brace of claim 4 , wherein at least one of the pair of hinges comprises an adjustable limiting mechanism configured to limit a range of motion of the hinge.

9. The brace of claim 8 , wherein the adjustable limiting mechanism comprises adjustable rods or adjustable pins extending through at least a portion of the hinge.

10. The brace of claim 1 , wherein the closure mechanism comprises at least one tightening strap that is anchorable to the leg support portion and actuatable to tighten the brace about the ankle from a loose state to a tightened state.

11. The brace of claim 10 , wherein said closure mechanism is positioned medially.

12. A method of stabilizing an ankle, comprising:
providing an ankle a flexible stabilizing ankle brace, comprising:
a heat-moldable, multi-layer a leg support portion,
a heat-moldable, multi-layer foot support portion,
a pair of hinges connecting said leg support portion to said foot support portion;
a locking mechanism configured to selectively couple with a body of at least one of the pair of hinges;
heating said ankle brace to between about 130° F. to about 220° F.;
applying said heated ankle brace to the ankle of a patient in need thereof such that a leg of the patient enters the ankle brace through a posterior opening in the ankle brace; and
coupling the locking mechanism to the body of at least one of the pair of hinges to limit motion of the hinge.

13. The method of claim 12 , wherein said multi-layer leg support portion and said multi-layer foot support portion each comprise a middle layer, wherein said middle layer is substantially stiff at a temperature below about 130° F. and moldable at temperatures between about 130° F. and 220° F.

14. The method of claim 13 , further comprising applying pressure to the heated leg support portion to mold the leg support portion to conform to a specific shape of a leg of the patient.

15. The method of claim 14 , further comprising applying pressure to the heated foot support portion to mold the foot support portion to conform to a specific shape of a foot of the patient.

16. The method of claim 15 , further comprising allowing the heated ankle brace to cool, and wherein the ankle brace is configured to retain its molded shape upon cooling.

17. The method of claim 16 , further comprising:
reheating the ankle brace to between about 130° F. to about 220° F. after it has cooled, thereby allowing it to become moldable;
reapplying applying pressure to the reheated leg support portion to mold the leg support portion to conform to a specific shape of a leg of the patient; and
applying pressure to the reheated foot support portion to mold the foot support portion to conform to a specific shape of a foot of the patient.

18. The method of claim 15 , further comprising manipulating the orientation of said brace to align the brace relative to said ankle.
