  • Publication number: 20080139980
    Abstract: A vibrostimulation device for slidingly communicating with tactile receptors in a human body. The device comprises an elongate vibrator module and a handle component configured for releasably engaging and rotationally communicating with the vibrator module. The vibrator module comprises a vibrating end portion containing therein an electrically controllable vibratory apparatus interconnected by a resilient shock-absorbing coupler to a power supply module. The resilient shock-absorbing coupler is configured to extend the vibrating portion away from the power supply module at an acute angle. The handle component comprises a base portion configured for releasably engaging and rotationally cooperating with the power supply module of the vibrator module, a vertical member pivotably cooperating with the base portion, and a cantilevered upper portion extending outward from the vertical portion.

  • Publication number: 20050079070
    Abstract: A kinetic pump and method of pumping a liquid comprising providing an acceleration tube for the acceleration of a liquid contained therein by an introduced high-pressure vapor or gas, receiving the liquid from the acceleration tube with a compressed-air surge tank, admitting the liquid from the acceleration tube into the compressed-air surge tank via a check valve, draining the liquid from the compressed-air surge tank from an outlet, and adding additional liquid to the acceleration tube via an inlet, wherein during each first half cycle of the method, the vapor or gas forces the liquid to accelerate in the acceleration tube, whereby a portion of the liquid is forced into the compressed-air surge tank, and wherein during each second half cycle of the pump, the vapor or gas is substantially removed from the acceleration tube and the liquid flows back to its original location and the additional liquid is added to the liquid.

  • Patent number: 5403278
    Abstract: Hematomas and false aneurysms can be treated using a device and method which locate and the provide access to the hematoma or aneurysm. Hemostatic material is then introduced into the hematoma or aneurysm through a new puncture in such a fashion that the hemostatic material does not project into a blood vessel. This can be done by passing a guide wire through a hollow needle, removing the needle, passing a dilator over the guide wire, passing a sheath over the dilator, and then removing the dilator and passing hemostatic material through the sheath into the hematoma or false aneurysm.

  • Patent number: 5028695
    Abstract: The invention concerns a process for the manufacture of collagen membranes for medical applications, in which process the collagen raw materials obtained from cattle or pig collagen are mechanically freed of fatty residues and treated with diluted alkali and acids and, if need be, enzymes. It is thoroughly washed between these steps to thus clean the collagen raw material eliminating the accompanying contamination. It is then processed further while obtaining a collagen matrix with a dry weight of approximately 25% by weight. Thus obtained are collagen membranes, in which the original integral cohesion remains and with which a fast hemostatic effect is achieved; said membranes are also extremely flexible and they adhere well to the surface of a wound.
