| 20210128337 | JOINT STABILIZATION DEVICE, PARTICULARLY FOR THE PATELLOFEMORAL JOINT - A joint stabilization device including at least support means positionable at the patellar portion of a leg of a patient; a sustaining element of elongated shape, having a first extremity and a second extremity opposite to each other, associated with the support means and positionable laterally to the patella of the patient; a first traction element and a second traction element associated with the first extremity and with the second extremity, respectively; and a first directing element and a second directing element which are associated with the sustaining element and interposed between the first extremity and the first traction element and between the second extremity and the second traction element respectively, wherein the first traction element and the second traction element are adapted to position the sustaining element in a predefined position, the first directing element and the second directing element being adjustable depending on the predefined position. | 2021-05-06 |
| 20210128338 | JOINT STABILIZATION GARMENTS - Technical garments including joint stabilization socks, sleeves, and other garments are disclosed. The exemplary garments disclosed herein include regions with material properties, such as tensile strengths, that are different from other regions of the garment. Particular regions of the exemplary garments include interwoven materials with substantially high tensile strengths for providing resistance/compression to targeted body parts (e.g., ankles, knees, shoulders, etc.) for preventing undesirable movement (e.g., that mimics medically-relevant taping patterns). In particular embodiments, the regions with higher tensile strengths are interwoven or integrated into a base material, such that the garment can be comfortably worn while also providing compression and support to targeted body parts. | 2021-05-06 |
| 20210128339 | ADJUSTABLE BOOT BRACE - An adjustable boot brace adapted to stretch and support an inflamed tissue and/or inflamed plantar fascia within a person's foot while healing. The adjustable boot brace includes an outer shell being formed from plastic, an inner padding formed from soft foam, a toe plate, and a hinge that pivotally connects the toe plate to the outer shell so a person can adjust the position and angle of their toes. Five hook and loop straps are used to position and hold the adjustable boot brace to a person's leg and foot, including two for a calf portion, two for a foot portion, and one for the toe plate. Furthermore, at least one adjustable hook and loop strap is used to hold the toe plate at a chosen angle with respect to the outer shell in order to stretch and support the inflamed tissue and/or inflamed plantar fascia within a person's foot while using the adjustable boot brace for healing. | 2021-05-06 |
| 20210128340 | DECOMPRESSION THERAPY TREATMENT SYSTEM - A treatment system includes an dressing having a decompression layer and an occlusive layer that secures the dressing about a treatment site, and defines a treatment chamber within which the decompression layer is positioned. Operation of an air displacement device fluidly coupled to the chamber causes the decompression layer to compress away from the tissue site, resulting in a pulling force being imparted onto the treatment site. This decompression of the tissue site increases the perfusion of blood and other fluids, and advantageously may reduce swelling at the treatment site. To increase the degree of lifting of the treatment site, the decompression layer is advantageously constructed to exhibit a parallel plate effect during use of the treatment system. For example, the decompression layer is constructed having a center of stiffness located closer to an outwardly-facing surface of the decompression layer than a tissue-facing surface of the decompression layer. | 2021-05-06 |
