Abstract: The present disclosure includes fixation devices, such as an orthopedic screw or implant, that comprises one or more porous elements or fenestrations to aid in osteo-integration of the fixation device. The fixation device may be additively manufactured using biocompatible materials such that the solid and porous aspects of the screw are fused together into a single construct. In yet another aspect, the fixation device comprises at least a portion or section incorporating a porous structure, which enables bony ingrowth through the porous section/portion of the screw, and thereby facilitates biocompatibility and improve mechanical characteristics. Methods for using the fixation device are also described herein.

Abstract: The present disclosure relates to embodiments of a patient-specific or patient-matched, customized apparatus for assisting in various surgical procedures. In varying embodiments, patient-specific guides may comprise multiple patient-specific surfaces for mating with the underlying patient anatomy and may further comprise one or more protrusions or projections for facilitating placement and attachment, at least temporarily, to the desired location of the patient's anatomy. The apparatus described herein are preferably used with cervical and/or certain thoracic levels of the human spine and may comprise single or multi-level guides for placement of instruments and/or implants during a variety of surgical procedures.

Abstract: A hydraulic machine has a first assembly and a second assembly movable in rotation relative to each other about an axis of rotation. The first assembly and the second assembly define an internal volume and are in contact along an interface. The interface between the first assembly and the second assembly is provided with a sealing element positioned in a housing connected to the internal volume via a first duct, and to the surrounding environment via a second duct. The first duct is provided with a sealing element adapted to isolate the housing from the internal volume, where a secondary cavity is formed in the first assembly or in the second assembly. The secondary cavity is connected to the housing and isolated from the internal volume.

Abstract: The rotating hydraulic machine (102) comprises: —a housing (10), —a shaft (20) movably mounted relative to the housing about an axis, —an apron (24) rigidly connected to the shaft and extending around at least a portion of the housing, —a cam (12) rigidly connected to either the housing or the shaft, —a cylinder block (42) rotationally connected to the other of either the housing or the shaft, the cylinder block comprising pistons capable of engaging with the cam to produce a relative rotation between the shaft and the housing, —first and second guide bearings (28) each bearing directly on the housing and the apron, and —at least a third guide bearing (37) bearing directly on the housing and the cylinder block.

Abstract: The invention relates to an assembly including a hydraulic apparatus having a rotor and a stator. The rotor is mounted so as to turn about a second rotation axis with respect to the stator and is secured to a device suitable for mounting a vehicle wheel. A pivot-pin element is intended to be mounted on an axle and is mounted so as to rotate about a first rotation axis with respect to the hydraulic apparatus. The stator is mounted so as to turn about the first rotation axis with respect to the axle. An air chamber is formed between the pivot-pin element and the hydraulic apparatus, the air chamber is connected to a distribution passage formed in the hydraulic apparatus. An axle passage is formed in the pivot-pin element so as to form a pneumatic passage between the pivot-pin element and the hydraulic apparatus.

Abstract: The invention relates to a hydraulic device including: a stator and a rotor, in which the rotor can rotate relative to the stator about a first axis of rotation; and a shaft mounted on the rotor such as to rotate therewith. The shaft has a wheel carrier provided at a proximal end thereof and designed to receive a rim and a tire. The shaft includes a through-channel extending from the proximal end to an opposing distal end. The hydraulic device includes an air chamber formed at the distal end of the shaft and connected to the through-channel. The through-channel and air chamber are produced such as to allow a flow of air in order to control the pressure of a tire.

Abstract: An assembly including a hydraulic device around a second axis of rotation by means of a proximal rolling-element bearing and a distal rolling-element bearing, the hydraulic device including a shaft, a multi-lobe cam, a cylinder block and a distributor, and a pivoting element adapted to be mounted on an axle, and movable in rotation relative to the hydraulic device around a first axis of rotation. Views along a plane defined by the second axis of rotation and the first axis of rotation, the proximal rolling-element bearing and the distal rolling-element bearing are positioned on either side of the first axis of rotation, in that the cylinder block is positioned between the first axis of rotation and the proximal rolling-element bearing.
