Abstract: A containment case assembly, including a tray and closing lid, comprises an upper frame that is configured to support from one to a plurality of removable screw decks is described. The screw decks have a column of first openings into which removable silicon plugs or inserts are positioned. The removable inserts include indicia or labels that indicate to a user the size of a surgical screw that is positioned in a row of second openings that are aligned in the screw deck immediately adjacent to one of the first openings. The upper frame of the containment case also has an inlet provided with a series of adjacent indicia or labels that are spaced at regular millimeter intervals for use in verifying the length of a surgical screw. The upper frame is further provided with a series of regularly spaced openings that have progressively larger sizes. These openings enable a user to verify the diameter of a surgical screw.

Abstract: A guidewire is provided with first and second helical members at the distal end of the guidewire. The helical members enmesh with each other in a retracted state. The second helical member is extended from the first helical member by rotating a tubular member and core member relative to each other. This causes the first and second helical members to be driven apart from each other along a helical path defined by the engagement between helical members.

Abstract: A proximal fitting for a catheter is provided for manipulating a guide wire. The proximal fitting includes a first hub and a second hub that engage one another. A collet having a passage can be inserted into the passage of the first hub while being unable to pass through the passages of the first and second hubs. A first portion of the collet has a convex angular surface and a slot that extends radially from the passage in at least one direction. The convex angular surface of the collet interfaces with a concave angular surface on the first hub or the second hub thereby compressing the passage of the collet in response to the first and second hubs engaging one another.
