Abstract: A connector for joining a first hollow structure to the side wall of a second hollow structure, the connector comprising a first component comprising an inner collar; a hollow body; and a graft mounted to the inner collar and forming a conduit through the hollow body and the inner collar; and a second component comprising an outer collar and a hollow body, the hollow body of the second component being sized for coaxial disposition over the hollow body of the first component so that the outer collar of the second component can be adjustably positioned relative to the inner collar of the first component and so that the conduit of the graft provides fluid communication between (i) the region beyond the inner collar, and (ii) the region beyond the hollow body of the first component.

Abstract: Apparatus for attaching a left ventricular assist device (LVAD) to a heart, the apparatus comprising: a connector conduit comprising: a distal end, a proximal end and a lumen extending between the distal end and the proximal end, wherein the distal end is configured to be inserted into a wall of the heart, and the proximal end is configured to receive the LVAD, whereby hemostasis is maintained during insertion of the connector conduit into the wall of the heart and during insertion of the LVAD into the proximal end of the connector conduit.

Abstract: A connector for joining a first hollow structure to the side wall of a second hollow structure, the connector comprising: a first component comprising: an inner collar for disposition within the interior of the second hollow structure, the inner collar having a toroidal configuration characterized by an outer perimeter and an inner perimeter, with the inner collar being flexible; a hollow body connected to the inner collar and upstanding therefrom, the hollow body of the inner collar being aligned with the inner perimeter of the inner collar; and a graft element mounted to the inner collar and forming a conduit extending through the hollow body and the inner perimeter of the inner collar, the graft being formed out of a fluid-retaining material; and a second component for disposition outside the second hollow structure, the second component comprising an outer collar and a hollow body connected to the outer collar, the outer collar having a toroidal configuration characterized by an outer perimeter and

Abstract: A bovine teat sanitizer includes a gun-like grip handle, trigger mechanism and control poppet valve connected to a pressurized sanitizing fluid supply. A fixed in-line teat cup sized to receive a predetermined volume of fluid from a proportioning valve sufficient for treating four teats of the bovine is connected to the handle. A toroidal overflow chamber receives displaced fluid from the cup when the cup captures and essentially seals a teat thus forcing sanitizing fluid into the teat strep canal and epidermis. The cup is lowered and displaced fluid from the overflow chamber returns to the cup cavity by gravity for use on the second and succeeding teats. A splash guard and teat guide snaps onto the cup and forms the chamber top and inner sides.

Abstract: An apparatus for mixing two fluids in precise proportions which includes a quantifying meter and a concentrate meter. The apparatus also includes apparatus connecting the quantifying meter and the concentrate meter to simultaneously operate the quantifying meter and concentrate meter. The quantifying meter includes a servo plunger that is elongated and further includes a piston and a sealing member. The piston and the sealing member are axially spaced and the quantifying meter also includes a servo piston having a central bore in which the servo plunger is disposed in coaxial relationship with the piston in sealing engagement with the central bore. The servo piston includes a pressure fluid entrance port and an axially spaced outlet bore.
