Abstract:

A power saw assembly including a base plate and having a powered blade assembly including a saw blade attached to the upper surface of the base plate. The powered blade assembly has at least one operating position for cutting material wherein the saw blade extends at least partially through a slot in said base plate. The power saw assembly further includes a fence assembly swivelable about a substantially vertical axis from a first position allowing the saw blade to cut through a piece of material at an angle of 90 degrees with respect to the length of the material, to other positions allowing the saw blade to cut through the material at angles other than 90 degrees with respect to the length of the material. The fence assembly is securable to the base plate at any position by clamping the fence assembly against the upper and lower surfaces of the base plate.

Abstract:

A percutaneous implant device is provided which is stable, biocompatible, substantially infection-free and provides a long-term port of entry into the body, the device having an easy-to-use, effective, contamination-resistant capping and valving system for the exchange of fluids into and out of the body. The device comprises a nonporous biocompatible conduit having an attached flange, the flange having a top and a bottom. In the preferred embodiment, at the top of the flange, where the flange and conduit connect, the conduit emerges from the flange, necks inwardly and then flares outwardly forming an hourglass configuration. Above this neck the conduit forms substantially a right-angle bend, the conduit then extending substantially parallel to the skin. The device is implanted in the body such that the flange is below the surface of the skin. The flange preferably is covered with a porous, biologically inert material which permits growth of connective tissue and vascularization.
