Abstract: A nerve regeneration device comprising a bioresorbable conduit and a matrix contained therein having elongate pores aligned with the longitudinal axis of the conduit. The matrix comprises collagen, fibronectin, laminin-1, and laminin-2, wherein the amount, by weight, of laminin-1 or laminin-2 is greater than the amount of fibronectin in the matrix.

Abstract: Head wearable devices and methods are disclosed where a head wearable device includes a headpiece including a headband and an occipital basket attached to the headband, and a first housing attached to the headband. A depth adjuster is attached to the first housing and configured to change, by controlling a distance between the occipital basket and the first housing, a depth of the headpiece. A second housing is attached to the occipital basket, and a headband adjuster is attached to the occipital basket to change a circumference of the headpiece by controlling a distance between respective opposing ends of the headband and the second housing.

Abstract: The present invention is directed to a nerve regeneration conduit including a resorbable tube having a matrix therein. The matrix is characterized by substantially parallel, axially aligned pores extending the length of the matrix. The matrix is formed by the axial freezing of a slurry having little or no significant radial thermal gradient during the freezing process. The matrix is used to bridge the gap between the severed ends of a nerve and provide a scaffold for nerve regeneration.

Abstract: The present invention is directed to an adherent resorbable matrix for use in surgical applications. The adherent resorbable matrix includes a biocompatible adherent material including chitosan.

Abstract: A headlight device includes a headband for encircling a head of a wearer, a padding system having a pad attached to at least a portion of the headband, the pad including a first layer and a second layer. The first layer includes a first cushioning material having a first durometer and or the second layer includes a second cushioning material having a second durometer, or the first layer is perforated in a first perforation pattern and or the second layer is perforated in a second perforation pattern.

Abstract: A head wearable device includes a headband, a housing attached to the headband, a luminaire, a duct system connecting the luminaire to the housing, a ball joint movably connecting the duct system to the luminaire, and an air moving device, which is adjacent to an exhaust of the housing and is configured to induce an air flow through an inlet in the luminaire through the ball joint, through the duct system, and out of the exhaust of the housing attached to the headband.

Abstract: Head wearable devices and methods are disclosed where a head wearable device includes a headpiece including a headband with a top strap, a first housing attached to an outer surface of the top strap of the headband, a depth adjuster attached to the first housing wherein the depth adjuster is configured to change a depth of the headpiece, and a headband adjuster configured to change a circumference of the headpiece.

Abstract: A head wearable device includes a headpiece, a housing attached to the headpiece, a luminaire attached to the headpiece, the luminaire including a luminaire housing and at least one light source located within the luminaire housing, a duct system connecting the luminaire to the housing, a ball joint rotatably connecting the duct system to the luminaire, and an air moving device configured to induce a cooling air flow through an inlet in the luminaire housing, through the heatsink, through the ball joint, through the duct system, and out of an exhaust in the housing attached to of the headpiece.
