Abstract: Apparatuses and methods for holding and supporting an intravenous catheter are disclosed, wherein the catheter support apparatus is adjustable and can be removed easily and rapidly. The catheter support apparatus includes an elongate member comprising a first end, an opposed second end, and a central portion located between the first end and the second end; a foldable strip member attached to the first end of the elongate member and adapted for movement between an open and a closed position; an attachment element adapted for removeably securing the second end on the elongate member to the inside surface of the strip member; and a closure element adapted for removeably securing the strip member in a closed position wherein the inside surface of the strip member is adapted for slidably engaging and supporting a portion of the exposed segment of the catheter.

Abstract: An implantable dual chambered catheter device includes a first chamber and a second chamber integrally joined. The first chamber includes a hollow first elastomeric member contained within a first slotted outer housing. A first end of the first elastomeric member is fitted with a first end cap shaped and dimensioned to accept conventional catheter tubes and the second end of the first elastomeric member is closed. The second chamber includes a hollow second elastomeric member contained within a second slotted outer housing. A first end of the second elastomeric member is fitted with a second end cap shaped and dimensioned to accept conventional catheter tubes and the second end of the second elastomeric member is closed. Needle access to the first and second chambers of the implantable catheter device is through respective slots formed within the first and second outer housings.

Abstract: A hollow medical needle having a bevel face defining a needle tip and cutting surface that create a first incision. The needle additionally has a separate cutting blade extending outward from the needle. The blade is positioned adjacent the bevel face to create a second incision which intersects the first incision made by the bevel face cutting surface.

Abstract: An apparatus and method is provided for preparing a tight proximal contact between a tooth to be filled and an adjacent tooth. A tool head provides a first convex surface extending downwardly to a linear ridge. The head is divided into a pair of side-by-side fingers separated by a channel. The linear ridge defines the tip of each finger. The head is of a size to fit into a prepared cavity in a tooth. The head further provides a stepped surface, in opposition to the first convex surface, that extends downwardly to the linear ridge. Alternately, the head provides a second convex surface, in opposition to the first convex surface, that extends downwardly to the linear ridge. An elongated tool handle has a first and a second opposing bent ends. The first bent end has a 90.degree. bend, and the second bent end has a 45.degree. bend, such that the single tool may enable the formation of both distal and mesial contacts.
