A device for delivering an occlusive element includes an elongate pusher member having a lumen. A locking member is disposed within the lumen of the elongate pusher member. A moveable elongate releasing member is disposed within the lumen of the elongate pusher member. A filament is secured to the distal end of the elongate releasing member. The occlusive member is locked to the elongate releasing member when the filament passes through a securing member on the occlusive member and is pinched or wedged between the locking member and the elongate releasing member. The occlusive element is in an unlocked state when the elongate releasing member is retracted proximally relative to the elongate pusher member. The filament, along with the elongate releasing member, are retracted proximally until the filament is detached or uncoupled from the securing member of the occlusive member.

A cartilage replacement or repair prosthesis comprises a layer of streamlined elastomer elements, preferably in the form of spheres, supported in a matrix material so that the radially opposed surfaces of the spheres are positioned on opposite surfaces of the layer and make contact with the opposed surfaces of the femur and tibia and the forces exerted between these bones extend through the streamlined elements. The matrix material has a substantially lower resistance to deformation than the spheres to control the position of the spheres relative to one another without significantly restraining their load-responsive deformation under forces exerted between the femur and tibia. The layer, with its elastomeric inserts, is sufficiently thin and flexible to allow it to be rolled for arthroscopic insertion into a knee joint.

The invention provides a triaxial compression rheological test system capable of simulating an engineering geological environment, belonging to rock material compression experimental facilities. The remarkable characteristics of the invention are as follows: a test chamber in the triaxial compression rheological test system capable of simulating the engineering geological environment can depend on a normal rheological compression test device to realize the analogue simulation of the variations of a temperature field, a humidity field and a chemical field in the engineering geological environment by utilizing a humidifier, a heater and a fluid tank. The device fundamentally solves the problems of larger deviation of rock mechanics parameters obtained by a laboratory test and a field in-situ test and analogue simulation of a geotechnical wall-rock multi-field coupling environment. The test system has compact structure and low cost, is rather easy to install and dismount test pieces, detectors, pipelines and lead wires, and has stronger adaptability on the test pieces with different lithologies and sizes, thereby providing a set of complete technology and means for the study on the mechanical behavior of the wall-rock stability under a complex engineering geological condition.

Preferably, information is obtained from the users through plural interactive algorithms designed to sharpen and perfect patient selection, preferably throughout the life of each trial. This creates a global clinical-trial patient engagement, recruitment and retention marketplace, which is open to patents and all trial stakeholders.

The invention discloses a drilling tool for stimulating vibration of a drill column. The drilling tool comprises an upper shell, a lower shell and a poppet valve device, wherein an adapter is arranged at the upper end of the upper shell; a piston rod is arranged below the adapter in a sliding manner; a hollow piston rod runner is arranged on the piston rod; the upper end of the lower shell is fixedly connected with the lower end of the piston rod; a guide drive device is arranged inside the lower shell, and the poppet valve device is arranged below the guide drive device. When the drilling tool for stimulating vibration of the drill column is connected into the drill column to drill, a special valve system is driven by drilling fluid to generate hydraulic impact for driving the lower drill column to carry out periodic vibration in an axial direction, so that the phenomena of dragging and sticky slip generated in the drilling process of a high-friction torsional section can be eliminated, the contact state between the drill column and a well wall is improved, the upper drilling pressure and torque are effectively transmitted to a drill bit, and the penetration rate is increased.

The present fluid pumping method for micro-fluidic devices uses gas bubbles to move fluid by light beams. The light beams are emitted to the fluid near the gas bubble through an optically transparent cover and correspondingly heat the fluid in the micro channels. The liquid temperature variation changes the surface tension of the gas bubble near the heated fluid side, therefore, a pressure gradient between the end portions of the gas bubble generates accordingly. By moving the light beams, the moved pressure difference will be achieved, which will drive the gas bubbles and pump the fluid. Such a fluid pumping can simplify the structure of a micro-fluidic device and eliminate heat loss because of using a controllable light beam.

A shifting device (1) is provided for the mechanical coupling-free transmission of shift commands to an automatic transmission of a motor vehicle (shift-by-wire shifting), with at least one housing and/or one frame and one selector lever for the manual selection of shift commands for the vehicle transmission in at least one shift gate. The selector lever can be moved manually into at least four positions (P, R, N, D), pivotable about at least one shift axis. A transmission device(s) is provided for transmitting the shift commands without mechanical coupling with the vehicle transmission (shift bay wire). A parking brake, engaged in the P position, locks at least a transmission output shaft. A mechanical coupling (16) is provided between the selector lever (2) and the transmission of the vehicle. This mechanical coupling (16) activates the parking brake exclusively and automatically when the selector lever (2) is engaged in the P position and is automatically uncoupled from the selector lever when the selector lever (2) is pivoted out beyond the adjacent position.

A golf tee setter according to the present invention allows golfers to use a real tee on a practice mat to practice their swing in golf driving ranges as if they are actually practicing on real ground. The golf tee setter is configured to be placed in the rubber tee hole of the practice mat and has a slit formed in a tee holder to hold the tee in substantially vertical position in relation to the practice mat to place a golf ball on the tee. The slit has a plurality of flaps extending from front and rear inner walls of the slit. The flaps are made of a flexible material to absorb any tilting force of the golf tee and prevents the golf tee from ejecting from the golf tee setter. The golf tee setter includes a base portion which has a slightly larger diameter than the body of the tee holder to enable the tee holder to be inserted into the practice mat from the top surface instead of from the bottom surface. In addition, a cord tethers the golf tee and the golf tee setter for repeated use of the golf tee.
