Abstract: A foam dispensing apparatus which includes a foamable liquid container and a foam generating device for mixing a gas with a foamable liquid. The foam generating device has a plurality of passages through which pressurized gas flows simultaneously with foamable liquid into the foam generating chamber past a flow restrictor. The passages are formed by a plurality of vertical flutes or horizontal grooves in one of the members.

Abstract: A foam producing device for the alternative dispensing of foams or liquids comprising a porous element comprising a partially gas permeable wall, a gas distribution plenum, a gas entry port in fluid connection with said plenum; a second wall opposite the outer surface of said gas permeable wall; a mixing chamber comprising at one end, the proximal end, a small annular opening between said gas permeable and second wall, comprising an orifice for the uniform distribution of foamable liquid therethrough into said chamber and at the distal end an exit port for the discharge of foams or liquids from said chamber said chamber being tapered, or not, as required; a liquid distribution plenum for the uniform distribution of said foamable liquids to said orifice and a liquid entry port in fluid connection, through a conduit, with said plenum wherein said plenum and a source of foamable liquid are in fluid connection through a conduit therebetween; with the proviso that only the portion of said gas permeable wall betwee

Abstract: Foaming device for mixing gas and foamable liquid in a container having a tube and cap configuration which enables the dispensing of foam from the container without need for squeezing or deforming the container.

Abstract: A surgical staple remover comprises first and second handle elements pivotally connected to each other. The front portion of the first handle element terminates in a pair of outwardly extending anvil sections having outside surfaces that diverge away from each other in the front to rear direction so that different size staples may be received thereon until the staples contact the diverging outside surfaces thereof. A blade section on the front portion of the second handle element is constructed and arranged for movement toward and away from the anvil sections, and the blade section has a lower concavely curved staple engaging edge. The curved edge engages a staple on the anvil sections with a downward and rearward force to produce a U-shaped bend in the crown of the staple to thereby facilitate its removal.

Abstract: A ligator device has handles which are linked to a center slide to make the same move rearwardly when the handles are squeezed together. A pair of jaws surround the front of the slide top and bottom and are connected to it so as to open when the handles are released and close when the handles are squeezed. The forward ends of the jaws carry anvils which, when closed, squeeze ligating clips shut which are supplied from a magazine.
