Spine stabilization devices, systems and methods are provided in which a single resilient member or spring is disposed on an elongate element that spans two attachment members attached to different spinal vertebrae. The elongate element passes through at least one of the two attachment members, permitting relative motion therebetween, and terminates in a stop or abutment. A second resilient member is disposed on the elongate element on an opposite side of the sliding attachment member, e.g., in an overhanging orientation. The two resilient members are capable of applying mutually opposing urging forces, and a compressive preload can be applied to one or both of the resilient members.

The at least one informational marker is determined to gather information about the location of the dental implant. Abutment dimensional information based on the three-dimensional image and the at least one informational marker is developed. Overmold rapid prototype dimensional information based on the three-dimensional image is developed. The overmold rapid prototype adapted to fit over the modified stone model is fabricated.

A biofunctional dental implant wherein a crown portion is connected to a root portion without the use of the conventional short screws, or the like. A flexible abutment projects upwardly from the root portion, and the crown portion is positioned in surrounding engagement with the flexible abutment. A threaded abutment post is advanced through the flexible abutment and into receipt by the root portion. The advancement of the abutment post through the flexible abutment generates an outward pushing force for causing a plurality of flexible splines of the abutment to bend outwardly and into engagement with an elastomeric cap of the crown portion for holding the crown portion atop the root portion. In one preferred embodiment, a replacement crown portion is detachably connected to an existing root portion by way of a removable abutment screw so as to enable a broken or worn crown portion to be removed and replaced without the need for a new surgery.

This prosthesis comprises a humeral or femoral component and an intermediate component. The concave surface of articulation of the humeral or femoral component is formed by a plate connected by a neck to a part of this component adapted to be anchored in the humeral or femoral medullary cavity. The intermediate component is provided with a member for retaining the humeral or femoral component in a position where the plate is in abutment against the first convex surface of the intermediate component. The retaining member defines a non-circular passage in which the neck is adapted to be displaced as a function of the movements of the humeral or femoral component with respect to the other components of the prosthesis. The retaining member defines with the first convex surface of articulation of the intermediate component a volume for receiving a part of the plate projecting radially with respect to the neck.

The invention relates to an orogastric catheter for a longitudinal gastrectomy. The object of the invention is to make available an orogastric catheter that represents an advantageous alternative to the poorly suited catheters used today and that facilitates the work of the surgeon. This novel orogastric catheter is characterized in that this distal part carries a balloon (25) which, in the inflated state, has a shape substantially matching that of the pyloric antrum (4), in such a way as to be able to be lodged in this pyloric antrum (4), the end of the inflated balloon (25) then being in abutment against the pylorus (5), and the distal end of the body of the catheter (20) for its part being in abutment against the pyloric antrum (4), while the part of the body (21) of the catheter (20) arranged above the inflated balloon (25) is wedged against the wall of the lesser curvature (6) of the stomach (1), thus making it possible to determine the position of the start of the closure resection line in the area of the pyloric antrum (4), to define the closure resection line, and to calibrate the pyloric antrum (4) and the gastric sleeve to be preserved.
