Patent number: 6676619Abstract: A method and apparatus for supporting a body part utilizes an external splint to form a brace. The splint includes an elongated sheath connected and an elongated support piece placed in the interior of the sheath. The support piece is formed of a stiff material and is shorter that the sheath in length so that it can move relative to the sheath. The support piece is preferably formed of a composite material. One or more splints may be used to form a brace. Here, a mounting piece secures the splint(s) and mounts on the body part. A casing may be used over the brace. Alternatively, the splints can be formed in the casing. The method then involves the steps of supporting the body part with the splint(s) and brace described above.Type: GrantFiled: February 23, 2001Date of Patent: January 13, 2004Inventor: Wayne R. Arden

The guard includes a reactive system impregnated into or coated onto a substrate, the system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure. A flexible pad is positioned on one side of the substrate along its length to provide a cushioning barrier between the hardened substrate and the protected bone of the athlete when the protective guard is in use.Type: GrantFiled: July 29, 1999Date of Patent: October 24, 2000Assignee: Parker Athletic Products, LLCInventor: Louis J.

Patent number: 6110137Abstract: An orthopaedic brace having a cuff formed as a single piece from bendable sheet material comprises a generally U-shaped frame having a center segment and two extensions projecting from the ends of the center segment in a common direction. The center segment has a reduced stiffness as compared to the extensions to permit the center segment to be more readily shaped to conform to the body part of a wearer. A molded one-piece covering, such as a thermoplastic material, forms a continuous covering surrounding portions of the cuff. The cuff may be fabricated by stamping it from a sheet of metal, such as aluminum, or a composite material. By forming the sheet such that it has a variable thickness along one edge thereof, the center segment may be formed by the portion of the sheet having reduced thickness, while the extensions may be formed from the remainder of the sheet.Type: GrantFiled: December 19, 1996Date of Patent: August 29, 2000Assignee: DJ Orthopedics, LLCInventors: Charles A. Bastyr, Joseph F. Nebolon

Patent number: 6110134Abstract: A low temperature synthetic splint/orthotic material having affixed thereto a layer of gel-like viscoelastic padding having a compressibility such that upon normal application of the padded splinting material to a body part exhibiting such as bony prominences, that the padding compresses but does not bottom out under normal usage whereby the bony prominence is supported over its extent along with the rest of the body part. In preferred embodiments a cover of fabric, foam or polymeric film is bonded over the viscoelastic padding to isolate body tissue from possible discomfort associated with some properties of the padding material.Type: GrantFiled: March 24, 1997Date of Patent: August 29, 2000Assignee: Smith & Nephew, Inc.Inventors: John N. Clark, Jr., Matthew J. Mercier

Patent number: 6106492Abstract: A carpal tunnel splint for being custom-fitted to a hand and wrist to be supported, and comprising an elongate, narrow flexible inner cushion layer for being placed on and conformed to the shape of the hand and wrist, an initially flexible intermediate layer overlying the inner cushion layer and an intermediate layer comprised of a fabric impregnated with a moisture-curable resin which hardens upon curing to form a rigid structure of the fabric which retains a shape into which it is molded during curing, thereby also holding the flexible inner cushion layer in a conforming shape against the hand and wrist. A flexible protective outer layer overlies the intermediate layer and is attached to the inner cushion layer for enclosing the intermediate layer and forming the inner layer, intermediate layer and outer layer into a single, integrated elongated, narrow splint structure.Type: GrantFiled: March 10, 1999Date of Patent: August 22, 2000Assignee: Smith & Nephew, Inc.Inventor: Thomas D.

Patent number: 6100206Abstract: The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour.Type: GrantFiled: November 4, 1997Date of Patent: August 8, 2000Assignee: 3M Innovative Properties CompanyInventors: Matthew T. Scholz, Jason L. Edgar, Andrew J. Callinan, Dean A. Ersfeld, Worku A. Mindaye

Patent number: 6077240Abstract: The present invention provides novel casting tapes incorporating water soluble liners. The liners of the present invention may be used for a number of purposes including: use as an interlayer film liner in a casting tape article to prevent undesirable resin pooling; use as an interlayer liner to lubricate a casting tape when immersed in water, use in a method of producing a decorative casting tape either by retarding layer-to-layer migration of a colored resin or by transferring a design preprinted on the liner to an adjacent casting tape; use as an interlayer liner in a casting tape article to prevent adhesion between adjacent layers of the article; and use as a release liner to facilitate removal of a roll of casting tape from its package. The liners employed in this invention are rapidly soluble in water and may be provided as a continuous or semi-continuous sheet structure.Type: GrantFiled: March 15, 1995Date of Patent: June 20, 2000Assignee: 3M Innovative Properties CompanyInventors: Matthew T.

Patent number: 6056713Abstract: This invention relates to a conformable ankle brace constructed of a heat moldable thermoplastic material that can be formed in place around a patient's injured ankle. The moldable thermoplastic material is shaped in a manner that produces medial and lateral extensions for covering the medial and lateral malleoli of a patient's foot. A concave recess is formed between the medial and lateral extensions to improve strength and reduce cracking of the thermoplastic brace. A non-stretchable strap holds the conformable ankle brace in position against the ankle and leg. A stretchable strap secures the medial and lateral extensions or splints in place over the medial and lateral malleoli. Strategically placed pads of hook-textured material, that mate with loop-type material on the fastening straps hold them in place on the ankle brace. Optionally, the moldable custom-fitted ankle brace can beheld in place with athletic tape.Type: GrantFiled: November 24, 1997Date of Patent: May 2, 2000Inventor: Melvin M. Hayashi
