Title
(EN) MATERIALS AND METHODS FOR PROTECTING AGAINST NEUROMAS
(FR) MATÉRIAUX ET PROCÉDÉS POUR LA PROTECTION CONTRE LES NÉVROMES
Abstract
(EN)
The subject invention provides devices and methods for alleviating discomfort associated with neuroma formation. The devices and methods of the invention effectively use the body's natural response of reconstructing implanted biomaterials to minimize the size of, isolate, and protect a neuroma. In preferred embodiments, the subject device is a cylindrical cap, wherein the internal chamber of the cylindrical cap physically partitions the nerve to enable an arrangement of nerve fibers (as opposed to haphazardly arranged nerve fibers often produced in neuromas). In addition, the cap's material remodels into a tissue cushion after implantation, which protects the neuroma from being stimulated and inducing pain.

La présente invention concerne des dispositifs et des procédés pour soulager l'inconfort associé à la formation de névrome. Les dispositifs et les procédés de l'invention utilisent efficacement la réponse naturelle du corps en reconstruisant les biomatériaux implantés pour minimiser la taille de l'isolat, et protéger contre un névrome. Dans des modes de réalisation préférés, le dispositif sujet est une capsule cylindrique, dans laquelle la chambre interne de la capsule cylindrique sépare physiquement le nerf pour permettre un arrangement des fibres nerveuses (par opposition aux fibres nerveuses disposées au hasard souvent produites dans les névromes). De plus, le matériau de la capsule est remodelé en un coussin de tissu après implantation, qui protège de la stimulation du névrome et de l'induction de la douleur.
