The subject matter of the invention is a three-dimensional molded body, in particular a milling blank, made of a polymerizable prosthetic material, which is suitable for milling machining by means of CNC and/or CAD/CAM, having a fracture toughness of greater than or equal to 1.9 Mpa.Math.m.sup.1/2 and a fracture work of greater than or equal to 900 J/m.sup.2. The milling blank preferably comprises core-shell particles modified by an elastic phase and is optionally based on a content of urethane (meth)acrylate polymerized into the polymer. Moreover, a subject matter of the invention is the use of the milling blanks for the production of at least parts of dental prosthetic parts, such as a prosthesis, artificial teeth, bridges, or of orthodontic appliances and instruments in medical field.

A method and process for providing three dimensional (3-D) virtual image of a patient in metaverse or 3-D hologram for surgical or other procedures, wherein the avatar of a medical practitioner, imitating the actions of the practitioner performing the procedure, can visually identify the organs and the location of the instruments in real-time inside patient. The image data stream generated in real time can be saved in a data base for later re-creation of the image. The re-creation of the image with spatial coordination and updating in time is usable as a review and a teaching/training tool. The implemented Metaverse provides all details collected and combined from the multiple imaging systems. It is usable as a diagnostic tool, a practice tool a teaching tool and real time direction and feedback tool by the medical community for procedures. The real-time image in Metaverse provides critical visual capabilities during procedures.

Bird carriers and methods of restraining birds are disclosed. Each bird carrier may include a torso support, one or more leg clamps, and a head support. The head support may further include a beak receiving passage such that at least a portion of the birds' beaks are exposed. The bird carriers may restrain one or both legs and heads of the birds while supporting their torsos. Restraining the legs and the heads of the birds while supporting their torsos may produce a calming effect such that the birds exhibit significantly reduced struggling in an attempt to free themselves from the carrier.

A surgical stacking needle for use in surgical procedures utilizing multiple filaments. The needle disclosed herein has an enlarged eye, relative to typical surgical needles, or has one or more eyes. Where the needle has a plurality of eyes, the multiple eyes are defined by one or more separators, providing strength to the needle and the eyes. The enlarged eye or the one or more eyes can be loaded with multiple filaments for use in surgical procedures. The needle may be straight, substantially straight, or curved.

An occlusion apparatus has a plastic ring with an opening at one point, encased in silicone, with a central opening of a first inside diameter, a silicone bladder in the circular, central opening, providing a hollow, semi-circular silicone ring, a mixture of sodium and potassium salts and polyacrylamide granules at a specific ration of materials enclosed in the silicone bladder, and two stirrups, one affixed on one side and the other opposite the first. The stirrups and the opening provide for spreading the apparatus by the stirrups to place the apparatus over a blood vessel, releasing the apparatus enclosing the blood vessel in the second inside diameter of the bladder, and wherein water passing through walls of the silicone bladder forms a hygroscopic gel that expands over time with further absorption of water, closing the second inside diameter of the silicone bladder, slowly occluding the blood vessel.

A system for treating a tissue of an animal patient. The system may include a display and input device, and at least one instrument chosen from an impulse stimulator instrument and an acoustic oscillator. The impulse stimulator is configured to apply a percussive massage including one or more force impulses. The impulse stimulator is further configured to measure a response of the tissue to one of the applied force impulses to assess a condition of the tissue. The acoustic oscillator is configured to apply an acoustic stimulation including one or more acoustic pulses to the tissue of the animal patient.

The invention relates to a balloon catheter device (1) for use in an aorta of a rabbit or a human being. The device (1) comprises a balloon catheter (2), a syringe (3), an actuator (4), a pressure sensor (5), a balloon retracting unit (6), a first control unit (7) and a second control unit (8). The balloon catheter (2) comprises a flexible tube (10) and a balloon (11) at a distal end (12) of the tube (10) and the syringe (3) comprises a chamber (16) containing a fluid, wherein the chamber (16) is connected to a proximal end of the tube (10). The actuator (4) is adapted for increasing/decreasing a volume of the fluid contained within the balloon (11). The pressure sensor (5) is adapted for sensing an inflation pressure of the balloon (11) and the balloon retracting unit (6) is adapted for retracting the balloon (11) out of the aorta. The first control unit (7) is adapted to receive pressure data representing the inflation pressure of the balloon (11) measured by the pressure sensor (5) and to control the actuator (4) depending on the received pressure data, such that the inflation pressure of the balloon (11) is kept stable at a predefined inflation pressure value, and the second control unit (8) is adapted to control the balloon retracting unit (6), such that the balloon (11) is retracted out of the aorta at a constant speed.
