CPC Class B33Y

A method for fitting a pre-existing standard helmet to the head of a user, the helmet includes an optronic device intended to be positioned in front of the eyes of the user, the method comprising: A) measuring the dimensions of the user's head, the dimensions of the head comprising a volume of the head and a position of the eyes, B) obtaining the dimensions of the helmet, the dimensions of the helmet including a volume of the helmet, C) defining a lining for the helmet so as to ensure the positioning of the optronic device in front of the user's eyes, the lining having a top face that is intended to be applied against an inner face of the helmet and a bottom face that is intended to be applied against the user's head, the lining having a flexible cellular structure, the manufacture of the lining being adapted to the dimensions of the head and to the dimensions of the helmet, D) manufacturing the lining as defined in step C), and E) placing the lining inside the helmet.

A method of manufacturing an elevator of a medical device comprises using an additive manufacturing method, forming a pivot portion at a proximal end of the elevator. The pivot portion tapers proximally such that a proximalmost end of the elevator is thinner than more distal portions of the pivot portion. The method further comprises using the additive manufacturing method, forming a body of the elevator that is distal to the pivot portion. The elevator body includes a surface configured to contact an instrument inserted in a working channel of the medical device.

A bone screw comprises a shaft defining a longitudinal axis and a minor diameter. The shaft including a core having an angled surface relative to the axis. The angled surface extending from the minor diameter adjacent a proximal portion of the shaft to a distal portion of the shaft, and a wall disposed about the angled surface. The wall including at least one thread having an external thread form. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

A custom tool for forming a dental restoration in a mouth of a patient. The custom tool includes a facial mold body for a patient-specific, customized fit with the facial side of at least one tooth of the patient, wherein the facial mold body includes a restorative portion, at least one aperture aligned with a portion of a surface of a tooth to be restored and at least one door having an inner surface forming a portion of the mold cavity encompassing missing tooth structure of the tooth to be restored, wherein the door mates with the aperture; a lingual mold body for a patient-specific, customized fit with the lingual side of the tooth of the patient, wherein the lingual mold body includes a restorative portion; wherein the facial mold body and lingual mold body are configured to interlock together; and wherein the facial mold body and lingual mold body are configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of at least one tooth to be restored.

The invention relates to a computer-implemented method for providing a holding splint for holding one or more restoration forms. The holding splint is configured for being arranged in a patient's oral cavity on a set of teeth comprising one or more teeth to be restored. The holding splint comprises one or more holding sections configured to hold the one or more restoration forms in order to shape restoration material applied onto one or more surfaces of the one or more teeth to be restored into a predefined form using the one or more restoration forms.
