An anatomic, neck-locking femoral prosthesis for use in total hip replacement is described. The asymmetric device fundamentally comprises a shell with a hollow bell-shape, which is anchored on the outside of retention neck and the trochantic bed of the femur. The prosthesis is mechanically fastened during the operation and further biologically secured by in-growing bone around the neck and trochantic bed area through the side holes on the shell and by growing into its interior porous coating surface of implant thereafter. The loading force on the femoral head would be well distributed on the shell and directly conducted into the cortex bone of the femoral shaft through the shell. The prosthesis would provide a simple and safe replacement method of hip prosthesis for most patients, particularly benefit for younger patient who has a defective head of femur. Because of less changes in term of anatomic structure of femur, new device could eliminate most of side effects and complications, which appear in regular stem type prosthesis of THA and thereafter.

A method and for establishing a virtual private network (VPN) session for a priority request. The method and apparatus includes identifying a priority request from a plurality of VPN session request classes. Reserved bandwidth is allocated to the priority request if a nominally allocated bandwidth is insufficient to satisfy the priority request. Once the allocated bandwidth is assigned, admission control is applied to the priority request.

Described here is a mechanism for a flow control device comprising of a valve casing, a plurality of buffer chambers, an elongated stem, and an actuating mechanism. The valve casing includes an inlet flow passage, an outlet flow passage, a valve seat in between, and a barrel housing extended from the flow passage. The buffer chamber is partitioned from the barrel housing by a moveable valve member and is comprised of a first channel and a second channel. The second channel is defined as a pilot valve and functions to adjust the inside pressure of the chamber. The elongated stem comprises of a plug that couples together with a pilot valve port.

A ready-for-use surgical kit and a facilitated protocol for the implantation of acetabular prosthesis in hip replacement surgery have been introduced. In particularly, a ready-for-use package includes both a set of the artificial acetabular prosthesis and a set of specific reamer(s) with a predefined spherical cutting profile. According to a protocol, surgeon could accurately select a package including both a size of acetabular prosthesis and a corresponding finishing reamer according to a pre-measurement and bone condition of a respective patient, and then patient-specifically remedy a defected acetabulum into a full hemispherical form having a personalized dimension by the reamer(s) within the package during operation.

A spherical reamer comprises at least two cutting elements having a support member and at least one circumference cutting member built on it. The cutting member can be characterized by edge configuration, geometric parameters or further by positional parameters, respectively. All variations of the parameters above lead various types of the cutting elements and methods of assembling either reusable or disposable reamer including self-assembling or/and “One Size Cutting Element for Assembling Several Size of Reamers” in order to fit into the application need in the field.
