Abstract: A system comprising a catheter having an expandable element, which when expanded, has an annular shape surrounding a passageway. The expandable element in the expanded state is rollable along at least a portion of the shaft of the catheter without slipping. The system may be used for delivering an object to a site in the body, retrieving an object from a body, removing debris and/or other particulate matter from a blood vessel, and distending and/or expanding a pathologically-involved region of a blood vessel wall.

Abstract: A device for effecting relative motion of movable components of a product within a closed sales display package translates a force exerted in one direction so that the force is applied in a second direction through buckling of a motion spring. The motion spring is two-dimensional, i.e., flat, and is oriented so that its flat surfaces face the direction of motion and so that its top and bottom edges are secured to opposite sides of a sales package. Pressure that is exerted vertically on the top and bottom edges of the spring causes the spring to buckle about a horizontal axis, thereby deflecting the flat surface of the spring in a horizontal direction that is perpendicular to both the vertical direction of force and the horizontal buckling axis. The motion spring is secured at its top and bottom vertical edges to the front and back, respectively, of the sales package. When the spring is to be used in conjunction with the rotatable toothbrush of U.S. Pat. Nos.

Abstract: An automatic self-inking, rubber-stamp device comprising a housing, ink pad, stamp plate and spring-loaded actuator. The device incorporates a guide pin integrally formed on the stamp plate and a cam formed on the housing wall which when the actuator is pressed down all act in coordination to turn the stamp plate over, from its resting position against the ink pad, to be pressed against the subject document. The device is further characterized by use of fewer components than in other products of the art, by its simplicity of construction and by its snap-together assembly thereby making it particularly suitable for automated and robotic assembly processes.

Abstract: The invention provides a toothbrush of the type having a plastic head and bristles terminating in the head and extending therefrom in an array, the toothbrush comprising an antibacterial composition embedded in pores created in the plastic head, which antibacterial composition is slowly releasable from the toothbrush into the buccal cavity during repeated use thereof during the life of the brush.
